As a Red Hat 3scale API Management administrator, there are general configuration options available to you in your installation or account to adjust settings.

1.1. Configuring a valid login session length
Copy link

As a Red Hat 3scale API Management administrator, you can configure a valid login session length for the Admin Portal and the Developer Portal so there is a limit for maximum timeout and inactivity.

To implement a valid login session length you must set USER_SESSION_TTL to seconds. For example 1,800 seconds is 30 minutes. If the value is null, that is, not set, or is set to an empty string, the session default length is for 2 weeks.

Prerequisites

  • A 3scale account with administrator privileges.

Procedure

  1. Update the USER_SESSION_TTL value in the system-app secret in seconds: 

    $ oc patch secret system-app -p '{"stringData": {"USER_SESSION_TTL": "'1800'"}}'

This section describes operations and scaling tasks of a Red Hat 3scale API Management 2.15 installation.

Prerequisites

To carry out 3scale operations and scaling tasks, perform the steps outlined in the following sections:

2.1. Redeploying APIcast
Copy link

You can test and promote system changes through the 3scale Admin Portal.

Prerequisites

  • A deployed instance of 3scale On-premises.
  • You have chosen your APIcast deployment method.

By default, APIcast deployments on OpenShift, both embedded and on other OpenShift clusters, are configured to allow you to publish changes to your staging and production gateways through the 3scale Admin Portal.

To redeploy APIcast on OpenShift:

Procedure

  1. Make system changes.
  2. In the Admin Portal, deploy to staging and test.
  3. In the Admin Portal, promote to production.

By default, APIcast retrieves and publishes the promoted update once every 5 minutes.

If you are using APIcast on the Docker containerized environment or a native installation, configure your staging and production gateways, and indicate how often the gateway retrieves published changes. After you have configured your APIcast gateways, you can redeploy APIcast through the 3scale Admin Portal.

To redeploy APIcast on the Docker containerized environment or a native installations:

Procedure

  1. Configure your APIcast gateway and connect it to 3scale On-premises.
  2. Make system changes.
  3. In the Admin Portal, deploy to staging and test.
  4. In the Admin Portal, promote to production.

APIcast retrieves and publishes the promoted update at the configured frequency.

2.2. Scaling up 3scale API Management On-premise
Copy link

As your APIcast deployment grows, you may need to increase the amount of storage available. How you scale up storage depends on which type of file system you are using for your persistent storage.

If you are using a network file system (NFS), you can scale up your persistent volume (PV) using this command: 

$ oc edit pv <pv_name>
Copy to Clipboard Toggle word wrap

If you are using any other storage method, you must scale up your persistent volume manually using one of the methods listed in the following sections.

Procedure

  1. Back up the data on your existing persistent volume.
  2. Create and attach a target persistent volume, scaled for your new size requirements.
  3. Create a pre-bound persistent volume claim, specify: The size of your new PVC (PersistentVolumeClaim) and the persistent volume name using the volumeName field.
  4. Restore data from your backup onto your newly created PV.

  5. Modify your deployment configuration with the name of your new PV: 

    $ oc edit deployment/system-app
    Copy to Clipboard Toggle word wrap
  6. Verify your new PV is configured and working correctly.
  7. Delete your previous PVC to release its claimed resources.

Procedure

  1. Back up the data on your existing persistent volume.
  2. Shut down your 3scale pods.
  3. Create and attach a target persistent volume, scaled for your new size requirements.
  4. Restore data from your backup onto your newly created PV.

  5. Create a pre-bound persistent volume claim. Specify:

    1. The size of your new PVC
    2. The persistent volume name using the volumeName field.
  6. Deploy your amp.yml.
  7. Verify your new PV is configured and working correctly.
  8. Delete your previous PVC to release its claimed resources.

The key deployment configurations to be scaled for 3scale are:

  • APIcast production
  • Backend listener
  • Backend worker
2.2.3.1. Scaling via the OCP
Copy link

Via OpenShift Container Platform (OCP) using an APIManager CR, you can scale the deployment configuration either up or down.

To scale a particular deployment configuration, use the following:

  • Scale up an APIcast production deployment configuration with the following APIManager CR: 

    apiVersion: apps.3scale.net/v1alpha1
kind: APIManager
metadata:
  name: example-apimanager
spec:
  apicast:
    productionSpec:
      replicas: X
    Copy to Clipboard Toggle word wrap

  • Scale up the backend listener, backend worker, and backend cron components of your deployment configuration with the following APIManager CR: 

    apiVersion: apps.3scale.net/v1alpha1
kind: APIManager
metadata:
  name: example-apimanager
spec:
  backend:
    listenerSpec:
      replicas: X
    workerSpec:
      replicas: Y
    cronSpec:
      replicas: Z
    Copy to Clipboard Toggle word wrap

  • Set the appropriate environment variable to the desired number of processes per pod.

    • PUMA_WORKERS for backend-listener pods: 

      $ oc set env deployment/backend-listener --overwrite PUMA_WORKERS=<number_of_processes>
      Copy to Clipboard Toggle word wrap

    • UNICORN_WORKERS for system-app pods: 

      $ oc set env deployment/system-app --overwrite UNICORN_WORKERS=<number_of_processes>
      Copy to Clipboard Toggle word wrap
2.2.3.2. Vertical and horizontal hardware scaling
Copy link

You can increase the performance of your 3scale deployment on OpenShift by adding resources. You can add more compute nodes as pods to your OpenShift cluster, as horizontal scaling or you can allocate more resources to existing compute nodes as vertical scaling.

Horizontal scaling

You can add more compute nodes as pods to your OpenShift. If the additional compute nodes match the existing nodes in your cluster, you do not have to reconfigure any environment variables.

Vertical scaling

You can allocate more resources to existing compute nodes. If you allocate more resources, you must add additional processes to your pods to increase performance.

Note

Avoid the use of computing nodes with different specifications and configurations in your 3scale deployment.

2.2.3.3. Scaling up routers
Copy link

As traffic increases, ensure your Red Hat OCP routers can adequately handle requests. If your routers are limiting the throughput of your requests, you must scale up your router nodes.

2.3. Operations troubleshooting
Copy link

This section explains how to configure 3scale audit logging to display on OpenShift, and how to access 3scale logs and job queues on OpenShift.

This enables all logs to be in one place for querying by Elasticsearch, Fluentd, and Kibana (EFK) logging tools. These tools provide increased visibility on changes made to your 3scale configuration, who made these changes, and when. For example, this includes changes to billing, application plans, application programming interface (API) configuration, and more.

Prerequisites

  • A 3scale 2.15 deployment.

Procedure

Configure audit logging to stdout to forward all application logs to standard OpenShift pod logs.

Some considerations:

  • By default, audit logging to stdout is disabled when 3scale is deployed on-premises; you need to configure this feature to have it fully functional.
  • Audit logging to stdout is not available for 3scale hosted.

2.3.2. Enabling audit logging
Copy link

3scale uses a features.yml configuration file to enable some global features. To enable audit logging to stdout, you must mount this file from a ConfigMap to replace the default file. The OpenShift pods that depend on features.yml are system-app and system-sidekiq.

Prerequisites

  • You must have administrator access for the 3scale project.

Procedure

  1. Enter the following command to enable audit logging to stdout: 

    $ oc patch configmap system -p '{"data": {"features.yml": "features: &default\n  logging:\n    audits_to_stdout: true\n\nproduction:\n  <<: *default\n"}}'
    Copy to Clipboard Toggle word wrap

  2. Export the following environment variable: 

    $ export PATCH_SYSTEM_VOLUMES='{"spec":{"template":{"spec":{"volumes":[{"emptyDir":{"medium":"Memory"},"name":"system-tmp"},{"configMap":{"items":[{"key":"zync.yml","path":"zync.yml"},{"key":"rolling_updates.yml","path":"rolling_updates.yml"},{"key":"service_discovery.yml","path":"service_discovery.yml"},{"key":"features.yml","path":"features.yml"}],"name":"system"},"name":"system-config"}]}}}}'
    Copy to Clipboard Toggle word wrap

  3. Enter the following command to apply the updated deployment configuration to the relevant OpenShift pods: 

    $ oc patch deployment system-app -p $PATCH_SYSTEM_VOLUMES

$ oc patch deployment system-sidekiq -p $PATCH_SYSTEM_VOLUMES
    Copy to Clipboard Toggle word wrap

2.3.3. Configuring logging for Red Hat OpenShift
Copy link

When you have enabled audit logging to forward 3scale application logs to OpenShift, you can use logging tools to monitor your 3scale applications.

For details on configuring logging on Red Hat OpenShift, see the following:

2.3.4. Accessing your logs
Copy link

Each component’s deployment configuration contains logs for access and exceptions. If you encounter issues with your deployment, check these logs for details.

Follow these steps to access logs in 3scale:

Procedure

  1. Find the ID of the pod you want logs for: 

    $ oc get pods
    Copy to Clipboard Toggle word wrap

  2. Enter oc logs and the ID of your chosen pod: 

    $ oc logs <pod>
    Copy to Clipboard Toggle word wrap

    The system pod has two containers, each with a separate log. To access a container’s log, specify the --container parameter with the system-provider and system-developer pods: 

    $ oc logs <pod> --container=system-provider

$ oc logs <pod> --container=system-developer
    Copy to Clipboard Toggle word wrap

2.3.5. Checking job queues
Copy link

Job queues contain logs of information sent from the system-sidekiq pods. Use these logs to check if your cluster is processing data. You can query the logs using the OpenShift CLI: 

$ oc get jobs
Copy to Clipboard Toggle word wrap 
$ oc logs <job>
Copy to Clipboard Toggle word wrap

2.3.6. Preventing monotonic growth
Copy link

To prevent monotonic growth, 3scale schedules by default, automatic purging of the following tables:

  • user_sessions

    Clean up is triggered once a week and deletes records older than two weeks.

  • audits

    Clean up is triggered once a day and deletes records older than three months.

  • log_entries

    Clean up triggered once a day and deletes records older than six months.

  • event_store_events

    Clean up is triggered once a week and deletes records older than a week.

With the exception of the above listed tables, the following table requires manual purging by the database administrator:

  • alerts

Additional resources

You can enable the Red Hat 3scale API Management monitoring using Prometheus and Grafana operators. Prometheus is an open-source monitoring and alerting tool designed to collect and analyze metrics from applications and infrastructure in real time. Grafana is an open-source analytics and visualization platform used to display and monitor real-time data from various sources in customizable dashboards.

Important

  • With the deprecation of Grafana 4 on OpenShift 4.16 and later, the instructions are split into two sections:

    • For OpenShift 4.15 and earlier.
    • For OpenShift 4.16 and later.
  • Grafana 5 is available on OpenShift 4.14 or later and supported by the 3scale 2.15 operator; using Grafana 5 is recommended when possible.
  • Red Hat support for Prometheus and Grafana is limited to the configuration recommendations provided in Red Hat product documentation.
  • The 3scale operator creates monitoring resources, but does not prevent modification of those resources.
  • You must install the 3scale operator and Prometheus operator in the same namespace or use cluster-wide operators.

The steps for migrating from Grafana 4 to Grafana 5 are also covered.

Prerequisites

  • The 3scale operator is installed.

  • The Prometheus operator is installed from the OperatorHub. You can use the Prometheus operator for creating and managing Prometheus instances. It provides the Prometheus custom resource definition (CRD) required by 3scale monitoring.

    The following Prometheus operator version is compatible with 3scale depending on your version of OpenShift Container Platform (OCP):

    • Latest Prometheus community operator with OCP 4.15 or earlier.
    • Latest Prometheus community operator with OCP 4.16 or later.

  • The Grafana operator is installed from the OperatorHub. You can use the Grafana operator for creating and managing Grafana instances. It provides the GrafanaDashboard CRD required by 3scale monitoring.

    The following Grafana operator versions are compatible with 3scale depending on your version of OCP:

    • Grafana community operator 4 with OCP 4.15 or earlier.
    • Grafana community operator 5 with OCP 4.16 or later.
Important

If your cluster is exposed on the Internet, make sure to protect the Prometheus and Grafana services.

This section describes how to enable monitoring of a 3scale instance, so that you can view the Grafana dashboards.

Configure Grafana and Prometheus for OpenShift Container Platform (OCP) versions up to 4.15. This guide walks through setting up these tools to monitor your 3scale environment, ensuring you get real-time insights and data visualization.

Additional resources

Webhooks is a feature that facilitates automation, and is also used to integrate other systems based on events that occur in 3scale. When specified events happen within the 3scale system, your applications will be notified with a webhook message. As an example, by configuring webhooks, you can use the data from a new account signup to populate your Developer Portal.

4.1. Overview of webhooks
Copy link

A webhook is a custom HTTP callback triggered by an event selected from the available ones in the Webhooks configuration window. When one of these events occurs, the 3scale system makes an HTTP or HTTPS request to the URL address specified in the webhooks section. With webhooks, you can configure the listener to invoke some desired behavior such as event tracking.

The format of the webhook is always the same. It makes a post to the endpoint with an XML document of the following structure: 

<?xml version="1.0" encoding="UTF-8"?>
<event>
  <type>application</type>
  <action>updated</action>
  <object>
    THE APPLICATION OBJECT AS WOULD BE RETURNED BY A GET ON THE ACCOUNT MANAGEMENT
    API
  </object>

    Gives you the subject of the event such as application, account, and so on.

  • <action>

    Specifies what has been done, by using values such as updated, created, deleted.

  • <object>

    Constitutes the XML object itself in the same format that is returned by the Account Management API. To check this, you can use our interactive ActiveDocs.

If you need to provide assurance that the webhook was issued by 3scale, expose an HTTPS webhook URL and add a custom parameter to your webhook declaration in 3scale. For example: https://your-webhook-endpoint?someSecretParameterName=someSecretParameterValue. Decide on the parameter name and value. Then, inside your webhook endpoint, check for the presence of this parameter value.

4.2. Configuring webhooks
Copy link

Procedure

  1. Select Account Settings from the Dashboard menu, then navigate to Integrate > Webhooks.

  2. Indicate the behavior for webhooks. There are two options:

    • Webhooks enabled: Select this checkbox to enable or disable webhooks.

    • Actions in the admin portal also trigger webhooks: Select this checkbox to trigger a webhook when an event happens.

      Consider the following:

      • When making calls to the internal 3scale APIs configured with the triggering events, use an access token; not a provider key.
      • If you leave this checkbox cleared, only actions in the Developer Portal trigger webhooks.
  3. Specify the URL address for notification of the selected events when they trigger.
  4. Select the events that will trigger the callback to the indicated URL address.

Once you have configured the settings, click Update webhooks settings to save your changes.

4.3. Troubleshooting webhooks
Copy link

If you experience an outage for your listening endpoint, you can recover failed deliveries. 3scale will consider a webhook delivered if your endpoint responds with a 200 code. Otherwise, it will retry 5 times with a 60 seconds gap. After any recovery from an outage, or periodically, you should run a check and if applicable clean up the queue. You can find more information about the following methods in ActiveDocs:

  • Webhooks list failed deliveries.
  • Webhooks delete failed deliveries.

5.3. Importing services
Copy link

Import services from a CSV file by specifying the following fields in the order specified below. Include these headers in your CSV file: 

service_name,endpoint_name,endpoint_http_method,endpoint_path,auth_mode,endpoint_system_name,type
Copy to Clipboard Toggle word wrap

You need the following information:

  • A 3scale admin account: {3SCALE_ADMIN}

  • The domain your 3scale instance is running on: {DOMAIN_NAME}

    • If you are using hosted APICast this is 3scale.net
  • The access key of your account: {ACCESS_KEY}
  • The CSV file of services, for example: examples/import_example.csv

Import the services by running:

Example

$ podman run -v $PWD/examples/import_example.csv:/tmp/import_example.csv registry.redhat.io/3scale-amp2/toolbox-rhel9:3scale2.15 3scale import csv --destination=https://{ACCESS_KEY}@{3SCALE_ADMIN}-admin.{DOMAIN_NAME} --file=/tmp/import_example.csv
Copy to Clipboard Toggle word wrap

This example uses a Podman volume to mount the resource file in the container. It assumes that the file is available in the current $PWD folder.

5.4. Copying services
Copy link

Create a new service based on an existing one from the same account or from another account. When you copy a service, the relevant ActiveDocs are also copied.

You need the following information:

  • The service id you want to copy: {SERVICE_ID}
  • A 3scale admin account: {3SCALE_ADMIN}

  • The domain your 3scale instance is running on: {DOMAIN_NAME}

    • If you are using hosted APICast this is 3scale.net
  • The access key of your account: {ACCESS_KEY}
  • The access key of the destination account if you are copying to a different account: {DEST_KEY}
  • The name for the new service: {NEW_NAME}

Example

$ podman run registry.redhat.io/3scale-amp2/toolbox-rhel9:3scale2.15 3scale copy service {SERVICE_ID} --source=https://{ACCESS_KEY}@{3SCALE_ADMIN}-admin.{DOMAIN_NAME} --destination=https://{DEST_KEY}@{3SCALE_ADMIN}-admin.{DOMAIN_NAME} --target_system_name={NEW_NAME}
Copy to Clipboard Toggle word wrap

Note

If the service to be copied has custom policies, make sure that their respective custom policy definitions already exist in the destination where the service is to be copied. To learn more about copying custom policy definitions check out the Copying a policy registry

5.5. Copying service settings only
Copy link

You can bulk copy the service and proxy settings, metrics, methods, application plans, application plan limits, as well as mapping rules from a service to another existing service.

You need the following information:

  • The service id you want to copy: {SERVICE_ID}
  • The service id of the destination: {DEST_ID}
  • A 3scale admin account: {3SCALE_ADMIN}

  • The domain your 3scale instance is running on: {DOMAIN_NAME}

    • If you are using hosted APICast this is 3scale.net
  • The access key of your account: {ACCESS_KEY}
  • The access key of the destination account: {DEST_KEY}

Additionally, you can use the optional flags:

  • The -f flag to remove existing target service mapping rules before copying.
  • The -r flag to copy only mapping rules to target service.
Note

The update command has been removed and replaced by the copy command.

The following example command does a bulk copy from one service to another existing service: 

$ podman run registry.redhat.io/3scale-amp2/toolbox-rhel9:3scale2.15 3scale copy [opts] service --source=https://{ACCESS_KEY}@{3SCALE_ADMIN}-admin.{DOMAIN_NAME} --destination=https://{DEST_KEY}@{3SCALE_ADMIN}-admin.{DOMAIN_NAME} {SERVICE_ID} {DEST_ID}
Copy to Clipboard Toggle word wrap

5.6. OpenAPI Authentication
Copy link

By implementing OpenAPI authentication with the 3scale toolbox, you can ensure that only authorized users have access to your APIs, safeguard sensitive data, and efficiently manage API usage. This approach will reinforces your API infrastructure and fosters trust among developers and consumers.

Note

Only one top-level security requirement is supported; operation-level security requirements are not supported.

Supported security schemes: apiKey and oauth2 with any flow type.

For the apiKey security scheme type:

  • The credentials location is read from the OpenAPI in field of the security scheme object.
  • Auth user key is read from the OpenAPI name field of the security scheme object.

Partial example of OpenAPI 3.0.2 with apiKey security requirement:

openapi: "3.0.2"
security:
  - petstore_api_key: []
components:
  securitySchemes:
    petstore_api_key:
      type: apiKey
      name: api_key
      in: header
      ...
Copy to Clipboard Toggle word wrap

For the oauth2 security scheme type:

  • The credentials location is hard-coded to headers.
  • OpenID Connect Issuer Type defaults to rest. You can be override this using the --oidc-issuer-type=<value> command option.
  • OpenID Connect Issuer is not read from OpenAPI. Since 3scale requires that the issuer URL must include a client secret, the issue must be set using this --oidc-issuer-endpoint=<value> command option.
  • OIDC AUTHORIZATION FLOW is read from the flows field of the security scheme object.

Partial example of OpenAPI 3.0.2 with oauth2 security requirement:

openapi: "3.0.2"
security:
    - petstore_oauth:
      - write:pets
      - read:pets
  components:
    securitySchemes:
      petstore_oauth:
        type: oauth2
        flows:
          clientCredentials:
            tokenUrl: http://example.org/api/oauth/dialog
            scopes:
              write:pets: modify pets in your account
              read:pets: read your pets
              ...
Copy to Clipboard Toggle word wrap

When OpenAPI does not specify any security requirements:

  • The product is considered as an Open API.
  • The default_credentials 3scale policy is added. Note: This is also called as anonymous_policy.
  • You require the command --default-credentials-userkey. Note: The command fails if is not provided.

5.7. Importing OpenAPI definitions
Copy link

To create a new service or to update an existing service, you can import the OpenAPI definition from a local file or a URL. The default service name for the import is specified by the info.title in the OpenAPI definition. However, you can override this service name using --target_system_name=<NEW NAME>. This will update the service name if it already exists, or create a new service name if it does not.

The import openapi command has the following format: 

$ 3scale import openapi [opts] -d <destination> <specification>
Copy to Clipboard Toggle word wrap

The OpenAPI <specification> can be one of the following:

  • /path/to/your/definition/file.[json|yaml|yml]
  • http[s]://domain/resource/path.[json|yaml|yml]

Example

$ podman run -v $PWD/my-test-api.json:/tmp/my-test-api.json registry.redhat.io/3scale-amp2/toolbox-rhel9:3scale2.15 3scale import openapi [opts] -d=https://{DEST_KEY}@{3SCALE_ADMIN}-admin.{DOMAIN_NAME} /tmp/my-test-api.json
Copy to Clipboard Toggle word wrap

Command options

The import openapi command options include:

-d --destination=<value>
3scale target instance in format: http[s]://<authentication>@3scale_domain.
-t --target_system_name=<value>
3scale target system name.
--backend-api-secret-token=<value>
Custom secret token sent by the API gateway to the backend API.
--backend-api-host-header=<value>
Custom host header sent by the API gateway to the backend API.

For more options, see the 3scale import openapi --help command.

OpenAPI import rules

The supported security schemes are apiKey and oauth2 with any OAuth flow type.

The OpenAPI specification must be one of the following:

  • Filename in the available path.
  • URL from where toolbox can download the content. The supported schemes are http and https.
  • Read from stdin standard input stream. This is controlled by setting the - value.

The following additional rules apply when importing OpenAPI definitions:

  • Definitions are validated as OpenAPI 2.0 or OpenAPI 3.0.
  • All mapping rules from the OpenAPI definition are imported. You can view these in API > Integration.
  • All mapping rules in the 3scale product are replaced.
  • Only methods included in the OpenAPI definition are modified.
  • All methods that were present only in the OpenAPI definition are attached to the Hits metric.
  • To replace methods, the method names must be identical to the methods defined in the OpenAPI definition operation.operationId by using exact pattern matching.
Note

The toolbox will add a default_credentials policy, which is also known as an anonymous_policy, if it is not already in the policy chain. The default_credentials policy will be configured with the userkey provided in an optional parameter --default-credentials-userkey.

OpenAPI 3.0 provides a way to specify security for your API using its security schemes and security requirements features. For more information, see the official Swagger Authentication and Authorization documentation.

OpenAPI 3.0 limitations

The following limitations apply when importing OpenAPI 3.0 definitions:

  • Only the first server.url element in the servers list is parsed as a private URL. The server.url element’s path component will be used as the OpenAPI’s basePath property.
  • The toolbox will not parse servers in the path item and servers in the operation objects.
  • Multiple flows in the security scheme object not supported.

You can use the toolbox import command to import an OpenAPI definition and create a 3scale backend API. The command line option --backend enables this feature. 3scale uses the OpenAPI definition to create and store a backend and its private base URL, as well as its mapping rules and methods.

Prerequisites

  • A user account with administrator privileges for a 3scale 2.15 On-Premises instance.
  • An OAS document that defines your API.

Procedure

  • Use the following format to run the import command to create a backend: 

    $ 3scale import openapi -d <remote> --backend <OAS>
    Copy to Clipboard Toggle word wrap
  • Replace <remote> with the URL for the 3scale instance in which to create the backend. Use this format: http[s]://<authentication>@3scale_domain

  • Replace <OAS> with the /path/to/your/oasdoc.yaml.

    Expand
    Table 5.1. Additional OpenAPI definition options
    OptionsDescription

    -o --output=<value>

    The output format. Can be either JSON or YAML.

    --override-private-base-url=<value>

    3scale reads the backend’s private endpoint from the OpenAPI definition’s servers[0].url field. To override the setting in that field, specify this option and replace <value> with the private base URL of your choice. When the OpenAPI definition does not specify a value in the servers[0].url field, and you do not specify this option in the import command, execution fails.

    --prefix-matching

    Use prefix matching instead of strict matching on mapping rules derived from OpenAPI operations.

    --skip-openapi-validation

    Skip OpenAPI schema validation.

    -t --target_system_name=<value>

    Target system name is a unique key in your tenant. System name can be inferred from the OpenAPI definition, however you can override that with your own name by using this parameter.

5.9. Managing remote access credentials
Copy link

To facilitate working with remote 3scale instances, you can use the 3scale toolbox to define the remote URL addresses and authentication details to access those remote instances in a configuration file. You can then refer to these remotes using a short name in any toolbox command.

The default location for the configuration file is $HOME/.3scalerc.yaml. However, you can specify another location using the THREESCALE_CLI_CONFIG environment variable or the --config-file <config_file> toolbox option.

When adding remote access credentials, you can specify an access_token or a provider_key:

  • http[s]://<access_token>@<3scale-instance-domain>
  • http[s]://<provider_key>@<3scale-instance-domain>

5.9.1. Adding remote access credentials
Copy link

The following example command adds a remote 3scale instance with the short <name> at <url>: 

$ 3scale remote add [--config-file <config_file>] <name> <url>
Copy to Clipboard Toggle word wrap

Example

$ podman run --name toolbox-container registry.redhat.io/3scale-amp2/toolbox-rhel9:3scale2.15 3scale remote add instance_a https://123456789@example_a.net

$ podman commit toolbox-container toolbox
Copy to Clipboard Toggle word wrap

This example creates the remote instance and commits the container to create a new image. You can then run the new image with the remote information included. For example, the following command uses the new image to show the newly added remote: 

$ podman run toolbox 3scale remote list
instance_a https://example_a.net 123456789
Copy to Clipboard Toggle word wrap

Other toolbox commands can then use the newly created image to access the added remotes. This example uses an image named toolbox instead of registry.redhat.io/3scale-amp2/toolbox-rhel9:3scale2.15.

Warning

Storing secrets for toolbox in a container is a potential security risk, for example when distributing the container with secrets to other users or using the container for automation. Use secured volumes in Podman or secrets in OpenShift.

5.18. Exporting products
Copy link

You can export a 3scale product definition in yaml format so that you can import that product into a 3scale instance that has no connectivity with the source 3scale instance. You must set up a 3scale product before you can export that product. See Creating new products to test API calls.

When two 3scale instances have network connectivity, use the toolbox 3scale copy command when you want to use the same 3scale product in both 3scale instances.

Description

When you export a 3scale product, the toolbox serializes the product definition in yaml format that adheres to the Product and Backend custom resource definitions (CRDs).

For more information, see Using the 3scale API Management operator to configure and provision 3scale.

Along with the basic information for the product, the output yaml includes:

  • Backends that are linked to the product.
  • Metrics, methods and mapping rules for linked backends.
  • Limits and pricing rules defined in application plans.
  • Metrics and methods that are referenced by limits and pricing rules.

Exporting a product is a read-only operation. In other words, it is safe to repeatedly export a product. The toolbox does not change the product being exported. If you want to, you can modify the yaml output before you import it into another 3scale instance.

Exporting a 3scale product is intended for the following situations:

  • There is no connectivity between the source and destination 3scale instances. For example, there might be severe network restrictions that prevent running the toolbox 3scale copy command when you want to use the same product in more than one 3scale instance.
  • You want to use Git or some other source control system to maintain 3scale product definitions in yaml format.

The 3scale toolbox export and import commands might also be useful for backing up and restoring product definitions.

Format

Use this format for running the export command: 

$ 3scale product export [-f output-file] <remote> <product>
Copy to Clipboard Toggle word wrap

The export command can send output to stdout or to a file. The default is stdout. To send output to a file, specify the -f or --file option with the name of a .yaml file.

Replace <remote> with a 3scale provider account alias or URL that is associated with the 3scale instance from which you are exporting the product. For more information about specifying this, see Managing remote access credentials.

Replace <product> with the system name or 3scale ID of the product that you want to export. This product must be associated with the 3scale provider account that you specified. You can find a product’s system name in the 3scale Admin Portal on the product’s Overview page. To obtain a product’s 3scale ID, run the toolbox 3scale services show command.

Example

The following command exports the petstore product from the 3scale instance associated with the my-3scale-1 provider account and outputs it to the petstore-product.yaml file: 

$ 3scale product export -f petstore-product.yaml my-3scale-1 petstore

Exporting and piping to Product CRs

When you run the export command you can pipe the output to create a product custom resource (CR). Which 3scale instance contains this CR depends on the following:

  • If the threescale-provider-account secret is defined, the 3scale operator creates the product CR in the 3scale instance identified by that secret.
  • If the threescale-provider-account secret is not defined, then if there is a 3scale instance installed in the namespace that the new product CR would be in, the 3scale operator creates the product CR in that namespace.
  • If the threescale-provider-account secret is not defined, and if the namespace that the new product CR would be in does not contain a 3scale instance, then the 3scale operator marks the product CR with a failed status.

Suppose that you run the following command in a namespace that contains a threescale-provider-account secret. The toolbox pipes the petstore CR to the 3scale instance identified in the threescale-provider-account secret: 

$ 3scale product export my-3scale-1 petstore | oc apply -f -

5.19. Importing products
Copy link

To use the same 3scale product in more than one 3scale instance when the source and destination 3scale instances do not have network connectivity, export a 3scale product from one 3scale instance and import it into another 3scale instance. To import a product, run the toolbox 3scale product import command.

When two 3scale instances have network connectivity, use the toolbox 3scale copy command when you want to use the same 3scale product in both 3scale instances.

Description

When you import a 3scale product, the toolbox expects a serialized product definition in .yaml format that adheres to the Product and Backend custom resource definitions (CRDs). You can obtain this .yaml content by running the toolbox 3scale product export command or by manually creating the .yaml formatted product definition.

If you exported the product, the imported definition contains what was exported, which can include:

  • Backends that are linked to the product.
  • Metrics, methods and mapping rules for linked backends.
  • Limits and pricing rules defined in application plans.
  • Metrics and methods that are referenced by limits and pricing rules.

If you want to, you can modify exported .yaml output before you import it into another 3scale instance.

The import command is idempotent. You can run it any number of times to import the same product and the resulting 3scale configuration remains the same. If there is an error during the import process, it is safe to re-run the command. If the import process cannot find the product in the 3scale instance, it creates the product. It also creates any metric, method, or backend that is defined in the .yaml definition and that it cannot find in the 3scale instance.

Importing a 3scale product is intended for the following situations:

  • There is no connectivity between the source and destination 3scale instances. For example, there might be severe network restrictions that prevent running the toolbox 3scale copy command when you want to use the same product in more than one 3scale instance.
  • You want to use Git or some other source control system to maintain 3scale product definitions in .yaml format.

The 3scale toolbox export and import commands might also be useful for backing up and restoring product definitions.

Format

Use this format for running the import command: 

$ 3scale product import [<options>] <remote>
Copy to Clipboard Toggle word wrap

The import command takes .yaml input from stdin or from a file. The default is stdin.

You can specify these options:

  • -f or --file followed by a file name obtains input from the .yaml file that you specify. This file must contain a 3scale product definition that adheres to the 3scale Product and Backend CRDs.
  • -o or --output followed by json or yaml outputs the report that lists what was imported in the format that you specify. The default output format is json.

Replace <remote> with a 3scale provider account alias or URL associated with the 3scale instance into which you want to import the product. For more information about specifying this, see Managing remote access credentials.

Example

The following command imports the product that is defined in petstore-product.yaml into the 3scale instance associated with the my-3scale-2 provider account. By default, the report of what was imported is in .json format. 

$ 3scale product import -f petstore-product.yaml my-3scale-2
Copy to Clipboard Toggle word wrap

The import command outputs a report that lists the imported items, for example: 

api:
  product_id: 2555417888846

    backend_01:
      backend_id: 73310

5.20. Export and import a product policy chain
Copy link

You can export or import your product’s policy chain to or from yaml or json content. In a command line, reference the product by its id or system value. You must set up a 3scale product before you can export or import a product’s policy chain. See: Creating new products to test API calls.

Features of the export command

  • The command is a read-only operation for remote products.
  • The command will write its output by default to the standard output stdout. The -f flag can be used to write the command’s output to a file.
  • Command output formats are in either json or yaml. Note that the default format is yaml.

Features of the the import command:

  • The command will read input from standard input or stdin. When -f FILE flag is set, input will be read from a file. When -u URL flag is set, input will be read from the URL.
  • The imported content can be either yaml or json. You do not need to specify the format because the toolbox automatically detects it.
  • The existing policy chain is overwritten with the newly imported one. SET semantics are then implemented.
  • All content validation is delegated to the 3scale API.

5.21. Copying API backends
Copy link

Create a copy of the specified source API backend on the specified 3scale system. The target system is first searched by the source backend system name by default:

  • If a backend with the selected system name is not found, it is created.
  • If a backend with the selected system name is found, it is replaced. Only missing metrics and methods are created, while mapping rules are entirely replaced with the new ones.

You can override the system name using the --target_system_name option.

Copied components

The following API backend components are copied:

  • Metrics
  • Methods
  • Mapping rules: these are copied and replaced.

Procedure

  • Enter the following command to copy an API backend: 

    $ 3scale backend copy [opts] -s <source_remote> -d <target_remote> <source_backend>
    Copy to Clipboard Toggle word wrap

    The specified 3scale instance can be a remote name or a URL.

    Note

    You can copy a single API backend only per command. You can copy multiple backends using multiple commands. You can copy the same backend multiple times by specifying a different --target_system_name name.

Use following options when copying API backends: 

Options
    -d --destination=<value>             3scale target instance: URL or
                                         remote name (required).
    -s --source=<value>                  3scale source instance: URL or
                                         remote name (required).
    -t --target_system_name=<value>      Target system name: defaults to
                                         source system name.

  • If a product with the selected system-name is not found, it is created.
  • If a product with the selected system-name is found, it is updated. Only missing metrics and methods are created, while mapping rules are entirely replaced with the new ones.

You can override the system name using the --target_system_name option.

Copied components

The following API product components are copied:

  • Configuration and settings
  • Metrics and methods
  • Mapping rules: these are copied and replaced.
  • Application plans, pricing rules, and limits
  • Application usage rules
  • Policies
  • Backends
  • ActiveDocs

Procedure

  • Enter the following command to copy an API product: 

    $ 3scale product copy [opts] -s <source_remote> -d <target_remote> <source_product>
    Copy to Clipboard Toggle word wrap

    The specified 3scale instance can be a remote name or a URL.

    Note

    You can copy a single API product only per command. You can copy multiple products using multiple commands. You can copy the same product multiple times by specifying a different --target_system_name name.

Use following options when copying API products: 

Options
    -d --destination=<value>             3scale target instance: URL or
                                         remote name (required).
    -s --source=<value>                  3scale source instance: URL or
                                         remote name (required).
    -t --target_system_name=<value>      Target system name: defaults to
                                         source system name.

5.23. Troubleshooting issues with SSL and TLS
Copy link

This section explains how to resolve issues with Secure Sockets Layer/Transport Layer Security (SSL/TLS).

If you are experiencing issues related to self-signed SSL certificates, you can download and use remote host certificates as described in this section. For example, typical errors include SSL certificate problem: self signed certificate or self signed certificate in certificate chain.

Procedure

  1. Download the remote host certificate using openssl. For example: 

    $ echo | openssl s_client -showcerts -servername self-signed.badssl.com -connect self-signed.badssl.com:443 2>/dev/null | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > self-signed-cert.pem
    Copy to Clipboard Toggle word wrap

  2. Ensure that the certificate is working correctly using curl. For example: 

    $ SSL_CERT_FILE=self-signed-cert.pem curl -v https://self-signed.badssl.com
    Copy to Clipboard Toggle word wrap

    If the certificate is working correctly, you will no longer get the SSL error. If the certificate is not working correctly, try running the curl command with the -k option (or its long form, --insecure). This indicates that you want to proceed even for server connections that are otherwise considered insecure.

  3. Add the SSL_CERT_FILE environment variable to your 3scale commands. For example: 

    $ podman run --env "SSL_CERT_FILE=/tmp/self-signed-cert.pem" -v $PWD/self-signed-cert.pem:/tmp/self-signed-cert.pem registry.redhat.io/3scale-amp2/toolbox-rhel9:3scale2.15 3scale service list https://{ACCESS_KEY}@{3SCALE_ADMIN}-admin.{DOMAIN_NAME}
    Copy to Clipboard Toggle word wrap

    This example uses a Podman volume to mount the certificate file in the container. It assumes that the file is available in the current $PWD folder.

    An alternative approach would be to create your own toolbox image using the 3scale toolbox image as the base image and then install your own trusted certificate store.

Additional resources

An API provider gives access to the APIs managed through the 3scale Admin Portal. You then deploy the API backends in many environments. API backend environments include the following:

  • Different environments used for development, quality assurance (QA), staging, and production.
  • Different environments used for teams or departments that manage their own set of API backends.

A Red Hat 3scale API Management product represents a single API or subset of an API, but it is also used to map and manage different API backend environments.

To find out about mapping API environments for your 3scale product, see the following sections:

6.1. Product per environment
Copy link

This method uses a separate 3scale Product for each API backend environment. In each product, configure a production gateway and a staging gateway, so the changes to the gateway configuration can be tested safely and promoted to the production configuration as you would with your API backends. 

Production Product => Production Product APIcast gateway => Production Product API upstream
Staging Product => Staging Product APIcast gateway => Staging Product API upstream
Copy to Clipboard Toggle word wrap

Configure the product for the API backend environment as follows:

Development environment

  • Create development backend

    • Name: Dev
    • Private Base URL: URL of the API backend

  • Create Dev product

    • Production Public Base URL: https://dev-api-backend.yourdomain.com
    • Staging Public Base URL: https://dev-api-backend.yourdomain.com
    • Add Dev Backend with a backend path /

QA environment

  • Create QA backend

    • Name: QA
    • Private Base URL: URL of the API backend

  • Create QA product

    • Production Public Base URL: https://qa-api-backend.yourdomain.com
    • Staging Public Base URL: https://qa-api-backend.yourdomain.com
    • Add QA Backend with a backend path /

Production environment

  • Create production backend

    • Name: Prod
    • Private Base URL: URL of the API backend

  • Create Prod product

    • Production Public Base URL: https://prod-api-backend.yourdomain.com
    • Staging Public Base URL: https://prod-api-backend.yourdomain.com
    • Add production Backend with a backend path /

6.2. 3scale API Management On-premises instances
Copy link

For 3scale On-premises instances, there are multiple ways to set up 3scale to manage API back-end environments.

  • A separate 3scale instance for each API back-end environment
  • A single 3scale instance that uses the multitenancy feature

In this approach, a separate 3scale instance is deployed for each API back-end environment. The benefit of this architecture is that each environment will be isolated from one another, therefore there are no shared databases or other resources. For example, any load testing being done in one environment will not impact the resources in other environments.

Note

This separation of installations has benefits as described above, however, it would require more operational resources and maintenance. These additional resources would be required on the OpenShift administration layer and not necessarily on the 3scale layer.

In this approach a single 3scale instance is used but the multitenancy feature is used to support multiple API back ends.

There are two options:

  • Create a 1-to-1 mapping between environments and 3scale products within a single tenant.

  • Create a 1-to-1 mapping between environments and tenants with one or more products per tenant as required.

    • There would be three tenants corresponding to API back-end environments - dev-tenant, qa-tenant, prod-tenant. The benefit of this approach is that it allows for a logical separation of environments but uses shared physical resources.
Note

Shared physical resources will ultimately need to be taken into consideration when analyzing the best strategy for mapping API environments to a single installation with multiple tenants.

6.3. 3scale API Management mixed approach
Copy link

The approaches described in 3scale API Management On-premises instances can be combined. For example:

  • A separate 3scale instance for production.
  • A separate 3scale instance with separate tenant for non-production environments in dev and qa.

6.4. 3scale API Management with APIcast gateways
Copy link

For 3scale On-premises instances, there are two alternatives to set up 3scale to manage API backend environments:

  • Each 3scale installation comes with two built-in APIcast gateways, for staging and production.
  • Deploy additional APIcast gateways externally to the OpenShift cluster where 3scale is running.

6.4.1. APIcast built-in default gateways
Copy link

When APIcast built-in gateways are used, the API back end configured using the above approaches described in 3scale API Management with APIcast gateways will be handled automatically. When a tenant is added by a 3scale Master Admin, a route is created for the tenant in production and staging built-in APIcast gateways. See Understanding multitenancy subdomains

  • <API_NAME>-<TENANT_NAME>-apicast-staging.<WILDCARD_DOMAIN>
  • <API_NAME>-<TENANT_NAME>-apicast-production.<WIDLCARD_DOMAIN>

Therefore, each API back-end environment mapped to a different tenant would get its own route. For example:

  • Dev <API_NAME>-dev-apicast-staging.<WILDCARD_DOMAIN>
  • QA <API_NAME>-qa-apicast-staging.<WILDCARD_DOMAIN>
  • Prod <API_NAME>-prod-apicast-staging.<WILDCARD_DOMAIN>

6.4.2. Additional APIcast gateways
Copy link

Additional APIcast gateways are those deployed on a different OpenShift cluster than the one on which 3scale instance is running. There is more than one way to set up and use additional APIcast gateways. The value of environment variable THREESCALE_PORTAL_ENDPOINT used when starting APIcast depends on how the additional APIcast gateways are set up.

A separate APIcast gateway can be used for each API back-end environment. For example: 

DEV_APICAST -> DEV_TENANT ; DEV_APICAST started with THREESCALE_PORTAL_ENDPOINT = admin portal for DEV_TENANT
QA_APICAST -> QA_TENANT ; QA_APICAST started with THREESCALE_PORTAL_ENDPOINT = admin portal for QA_APICAST
PROD_APICAST -> PROD_TENANT ; PROD_APICAST started with THREESCALE_PORTAL_ENDPOINT = admin portal for PROD_APICAST
Copy to Clipboard Toggle word wrap

The THREESCALE_PORTAL_ENDPOINT is used by APIcast to download the configuration. Each tenant that maps to an API backend environment uses a separate APIcast gateway. The THREESCALE_PORTAL_ENDPOINT is set to the Admin Portal for the tenant containing all the product configurations specific to that API backend environment.

A single APIcast gateway can be used with multiple API back-end environments. In this case, THREESCALE_PORTAL_ENDPOINT is set to the Master Admin Portal.

Additional resources

This topic explains the concepts of the API lifecycle with Red Hat 3scale API Management and shows how API providers can automate the deployment stage using Jenkins Continuous Integration/Continuous Deployment (CI/CD) pipelines with 3scale toolbox commands. It describes how to deploy the sample Jenkins CI/CD pipelines, how to create a custom Jenkins pipeline using the 3scale shared library, and how to create a custom pipeline from scratch:

7.1. Overview of the API lifecycle stages
Copy link

The API lifecycle describes all the required activities from when an API is created until it is deprecated. 3scale enables API providers to perform full API lifecycle management. This section explains each stage in the API lifecycle and describes its goal and expected outcome.

The following diagram shows the API provider-based stages on the left, and the API consumer-based stages on the right:

API lifecycle stages
View larger image
API lifecycle stages
Note

Red Hat currently supports the design, implement, deploy, secure, and manage phases of the API provider cycle, and all phases of the API consumer cycle.

7.1.1. API provider cycle
Copy link

The API provider cycle stages are based on specifying, developing, and deploying your APIs. The following describes the goal and outcome of each stage:

Expand
Table 7.1. API provider lifecycle stages
StageGoalOutcome

1. Strategy

Determine the corporate strategy for the APIs, including goals, resources, target market, timeframe, and make a plan.

The corporate strategy is defined with a clear plan to achieve the goals.

2. Design

Create the API contract early to break dependencies between projects, gather feedback, and reduce risks and time to market (for example, using Apicurio Studio).

A consumer-focused API contract defines the messages that can be exchanged with the API. The API consumers have provided feedback.

3. Mock

Further specify the API contract with real-world examples and payloads that can be used by API consumers to start their implementation.

A mock API is live and returns real-world examples. The API contract is complete with examples.

4. Test

Further specify the API contract with business expectations that can be used to test the developed API.

A set of acceptance tests is created. The API documentation is complete with business expectations.

5. Implement

Implement the API, using an integration framework such as Red Hat Fuse or a development language of your choice. Ensure that the implementation matches the API contract.

The API is implemented. If custom API management features are required, 3scale APIcast policies are also developed.

6. Deploy

Automate the API integration, tests, deployment, and management using a CI/CD pipeline with 3scale toolbox.

A CI/CD pipeline integrates, tests, deploys, and manages the API to the production environment in an automated way.

7. Secure

Ensure that the API is secure (for example, using secure development practices and automated security testing).

Security guidelines, processes, and gates are in place.

8. Manage

Manage API promotion between environments, versioning, deprecation, and retirement at scale.

Processes and tools are in place to manage APIs at scale (for example, semantic versioning to prevent breaking changes to the API).

7.1.2. API consumer cycle
Copy link

The API consumer cycle stages are based on promoting, distributing, and refining your APIs for consumption. The following describes the goal and outcome of each stage:

Expand
Table 7.2. API consumer lifecycle stages
StageGoalOutcome

9. Discover

Promote the API to third-party developers, partners, and internal users.

A developer portal is live and up-to-date documentation is continuously pushed to this developer portal (for example, using 3scale ActiveDocs).

10. Develop

Guide and enable third-party developers, partners, and internal users to develop applications based on the API.

The developer portal includes best practices, guides, and recommendations. API developers have access to a mock and test endpoint to develop their software.

11. Consume

Handle the growing API consumption and manage the API consumers at scale.

Staged application plans are available for consumption, and up-to-date prices and limits are continuously pushed. API consumers can integrate API key or client ID/secret generation from their CI/CD pipeline.

12. Monitor

Gather factual and quantified feedback about API health, quality, and developer engagement (for example, a metric for Time to first Hello World!).

A monitoring system is in place. Dashboards show KPIs for the API (for example, uptime, requests per minute, latency, and so on).

13. Monetize

Drive new incomes at scale (this stage is optional).

For example, when targeting a large number of small API consumers, monetization is enabled and consumers are billed based on usage in an automated way.

7.2. Deploying the sample Jenkins CI/CD pipelines
Copy link

API lifecycle automation with 3scale toolbox focuses on the deployment stage of the API lifecycle and enables you to use CI/CD pipelines to automate your API management solution. This topic explains how to deploy the sample Jenkins pipelines that call the 3scale toolbox:

7.2.1. Sample Jenkins CI/CD pipelines
Copy link

The following samples are provided in the Red Hat Integration repository as examples of how to create and deploy your Jenkins pipelines for API lifecycle automation:

These samples use a 3scale Jenkins shared library that calls the 3scale toolbox to demonstrate key API management capabilities. After you have performed the setup steps in this topic, you can install the pipelines using the OpenShift templates provided for each of the sample use cases in the Red Hat Integration repository.

Important

The sample pipelines and applications are provided as examples only. The underlying APIs, CLIs, and other interfaces leveraged by the sample pipelines are fully supported by Red Hat. Any modifications that you make to the pipelines are not directly supported by Red Hat.

Setting up a 3scale Hosted environment is required by all of the sample Jenkins CI/CD pipelines.

Note

The SaaS - API key, Multi-environment, and Semantic versioning sample pipelines use 3scale Hosted only. The Hybrid - open and Hybrid - OIDC pipelines also use 3scale On-premises. See also Setting up your 3scale On-premises environment.

Prerequisites

Procedure

  1. Log in to your 3scale Hosted Admin Portal console.
  2. Generate a new access token with write access to the Account Management API.

  3. Save the generated access token for later use. For example: 

    $ export SAAS_ACCESS_TOKEN=123...456
    Copy to Clipboard Toggle word wrap

  4. Save the name of your 3scale tenant for later use. This is the string before -admin.3scale.net in your Admin Portal URL. For example:

           -p PRIVATE_BASE_URL="http://$BEER_CATALOG_HOSTNAME" \
           -p NAMESPACE="$TOOLBOX_NAMESPACE" |oc create -f -
    Copy to Clipboard Toggle word wrap

  2. Deploy the sample as follows: 

    $ oc start-build saas-usecase-apikey
    Copy to Clipboard Toggle word wrap

Additional resource

The following limitations apply in this release:

OpenShift support
The sample pipelines are supported on OpenShift 3.11 only. OpenShift 4 is currently not supported. For more information about supported configurations, see the Red Hat 3scale API Management Supported Configurations page.
Updating applications
  • You can use the 3scale application apply toolbox command for applications to both create and update applications. Create commands support account, plan, service, and application key.
  • Update commands do not support changes to account, plan, or service. If changes are passed, the pipelines will be triggered, no errors will be shown, but those fields will not be updated.
Copying services
When using the 3scale copy service toolbox command to copy a service with custom policies, you must copy the custom policies first and separately.

This section provides best practices for creating a custom Jenkins pipeline that uses the 3scale toolbox. It explains how to write a Jenkins pipeline in Groovy that uses the 3scale Jenkins shared library to call the toolbox based on an example application. For more details, see Jenkins shared libraries.

Important

Red Hat supports the Jenkins pipeline samples provided in the Red Hat Integration repository.

Any modifications made to these pipelines are not directly supported by Red Hat. Custom pipelines that you create for your environment are not supported.

Prerequisites

Procedure

  1. Add the following to the beginning of your Jenkins pipeline to reference the 3scale shared library from your pipeline: 

    #!groovy

library identifier: '3scale-toolbox-jenkins@master',
   retriever: modernSCM([$class: 'GitSCMSource',
     remote: 'https://github.com/rh-integration/3scale-toolbox-jenkins.git'])
    Copy to Clipboard Toggle word wrap

  2. Declare a global variable to hold the ThreescaleService object so that you can use it from the different stages of your pipeline. 

    def service = null
    Copy to Clipboard Toggle word wrap

  3. Create the ThreescaleService with all the relevant information: 

    stage("Prepare") {
  service = toolbox.prepareThreescaleService(
     openapi: [ filename: "swagger.json" ],
     environment: [ baseSystemName: "my_service" ],
     toolbox: [ openshiftProject: "toolbox",

    • openapi.filename is the path to the file containing the OpenAPI specification.
    • environment.baseSystemName is used to compute the final system_name, based on environment.environmentName and the API major version from the OpenAPI specification info.version.
    • toolbox.openshiftProject is the OpenShift project in which Kubernetes jobs will be created.
    • toolbox.secretName is the name of the Kubernetes secret containing the 3scale toolbox configuration file, as shown in Installing the 3scale API Management toolbox and enabling access.
    • toolbox.destination is the name of the 3scale toolbox remote instance.
    • applicationPlans is a list of application plans to create by using a .yaml file or by providing application plan property details.

  4. Add a pipeline stage to provision the service in 3scale: 

    stage("Import OpenAPI") {
  service.importOpenAPI()
  echo "Service with system_name ${service.environment.targetSystemName} created !"
}
    Copy to Clipboard Toggle word wrap

  5. Add a stage to create the application plans: 

    stage("Create an Application Plan") {
  service.applyApplicationPlans()
}

  7. Add a stage to run your integration tests. When using APIcast Hosted instances, you must fetch the proxy definition to extract the staging public URL: 

    stage("Run integration tests") {
  def proxy = service.readProxy("sandbox")
  sh """set -e +x
  curl -f -w "ListBeers: %{http_code}\n" -o /dev/null -s ${proxy.sandbox_endpoint}/api/beer -H 'api-key: ${service.applications[0].userkey}'

7.4. Creating pipelines using a Jenkinsfile
Copy link

This section provides best practices for writing a custom Jenkinsfile from scratch in Groovy that uses the 3scale toolbox.

Important

Red Hat supports the Jenkins pipeline samples provided in the Red Hat Integration repository.

Any modifications made to these pipelines are not directly supported by Red Hat. Custom pipelines that you create for your environment are not supported. This section is provided for reference only.

Prerequisites

Procedure

  1. Write a utility function to call the 3scale toolbox. The following creates a Kubernetes job that runs the 3scale toolbox: 

    #!groovy

def runToolbox(args) {
  def kubernetesJob = [
    "apiVersion": "batch/v1",
    "kind": "Job",
    "metadata": [
      "name": "toolbox"
    ],
    "spec": [
      "backoffLimit": 0,
      "activeDeadlineSeconds": 300,
      "template": [
        "spec": [
          "restartPolicy": "Never",
          "containers": [
            [
             "name": "job",
             "image": "registry.redhat.io/3scale-amp2/toolbox-rhel9:3scale2.15",
             "imagePullPolicy": "Always",
             "args": [ "3scale", "version" ],
             "env": [
               [ "name": "HOME", "value": "/config" ]
             ],
             "volumeMounts": [
               [ "mountPath": "/config", "name": "toolbox-config" ],
               [ "mountPath": "/artifacts", "name": "artifacts" ]
              ]
            ]
          ],
          "volumes": [
            [ "name": "toolbox-config", "secret": [ "secretName": "3scale-toolbox" ] ],
            [ "name": "artifacts", "configMap": [ "name": "openapi" ] ]
          ]
        ]
      ]
    ]
  ]

  kubernetesJob.spec.template.spec.containers[0].args = args

  sh "rm -f -- job.yaml"
  writeYaml file: "job.yaml", data: kubernetesJob

  sh """set -e
  oc delete job toolbox --ignore-not-found
  sleep 2
  oc create -f job.yaml
  sleep 20 # Adjust the sleep duration to your server velocity
  """

  def logs = sh(script: "set -e; oc logs -f job/toolbox", returnStdout: true)
  echo logs
  return logs
}
    Copy to Clipboard Toggle word wrap

    Kubernetes object template

    This function uses a Kubernetes object template to run the 3scale toolbox, which you can adjust to your needs. It sets the 3scale toolbox CLI arguments and writes the resulting Kubernetes job definition to a YAML file, cleans up any previous run of the toolbox, creates the Kubernetes job, and waits:

    • You can adjust the wait duration to your server velocity to match the time that a pod needs to transition between the Created and the Running state. You can refine this step using a polling loop.
    • The OpenAPI specification file is fetched from a ConfigMap named openapi.
    • The 3scale Admin Portal hostname and access token are fetched from a secret named 3scale-toolbox, as shown in Installing the 3scale API Management toolbox and enabling access.
    • The ConfigMap will be created by the pipeline in step 3. However, the secret was already provisioned outside the pipeline and is subject to Role-Based Access Control (RBAC) for enhanced security.

  2. Define the global environment variables to use with 3scale toolbox in your Jenkins pipeline stages. For example:

    3scale Hosted

    def targetSystemName = "saas-apikey-usecase"
def targetInstance = "3scale-saas"
def privateBaseURL = "http://echo-api.3scale.net"
def testUserKey = "abcdef1234567890"
def developerAccountId = "john"
    Copy to Clipboard Toggle word wrap

    3scale On-premises

    When using self-managed APIcast or an on-premises installation of 3scale, you must declare two more variables: 

    def publicStagingBaseURL = "http://my-staging-api.example.test"
def publicProductionBaseURL = "http://my-production-api.example.test"
    Copy to Clipboard Toggle word wrap

    The variables are described as follows:

    • targetSystemName: The name of the service to be created.
    • targetInstance: This matches the name of the 3scale remote instance created in Installing the 3scale API Management toolbox and enabling access.
    • privateBaseURL: The endpoint host of your API backend.
    • testUserKey: The user API key used to run the integration tests. It can be hardcoded as shown or generated from an HMAC function.
    • developerAccountId: The ID of the target account in which the test application will be created.
    • publicStagingBaseURL: The public staging base URL of the service to be created.
    • publicProductionBaseURL: The public production base URL of the service to be created.

  3. Add a pipeline stage to fetch the OpenAPI specification file and provision it as a ConfigMap on OpenShift as follows: 

    node() {
 stage("Fetch OpenAPI") {
   sh """set -e
   curl -sfk -o swagger.json https://raw.githubusercontent.com/microcks/api-lifecycle/master/beer-catalog-demo/api-contracts/beer-catalog-api-swagger.json
   oc delete configmap openapi --ignore-not-found
   oc create configmap openapi --from-file="swagger.json"
   """
 }
    Copy to Clipboard Toggle word wrap

  4. Add a pipeline stage that uses the 3scale toolbox to import the API into 3scale:

    3scale Hosted

    stage("Import OpenAPI") {
  runToolbox([ "3scale", "import", "openapi", "-d", targetInstance, "/artifacts/swagger.json", "--override-private-base-url=${privateBaseURL}", "-t", targetSystemName ])
}
    Copy to Clipboard Toggle word wrap

    3scale On-premises

    When using self-managed APIcast or an on-premises installation of 3scale, you must also specify the options for the public staging and production base URLs: 

    stage("Import OpenAPI") {
  runToolbox([ "3scale", "import", "openapi", "-d", targetInstance, "/artifacts/swagger.json", "--override-private-base-url=${privateBaseURL}", "-t", targetSystemName, "--production-public-base-url=${publicProductionBaseURL}", "--staging-public-base-url=${publicStagingBaseURL}" ])
}
    Copy to Clipboard Toggle word wrap

  5. Add pipeline stages that use the toolbox to create a 3scale application plan and an application: 

    stage("Create an Application Plan") {
  runToolbox([ "3scale", "application-plan", "apply", targetInstance, targetSystemName, "test", "-n", "Test Plan", "--default" ])
}

stage("Create an Application") {
  runToolbox([ "3scale", "application", "apply", targetInstance, testUserKey, "--account=${developerAccountId}", "--name=Test Application", "--description=Created by Jenkins", "--plan=test", "--service=${targetSystemName}" ])
}
    Copy to Clipboard Toggle word wrap 
    stage("Run integration tests") {
  def proxyDefinition = runToolbox([ "3scale", "proxy", "show", targetInstance, targetSystemName, "sandbox" ])
  def proxy = readJSON text: proxyDefinition
  proxy = proxy.content.proxy

  sh """set -e
  echo "Public Staging Base URL is ${proxy.sandbox_endpoint}"
  echo "userkey is ${testUserKey}"
  curl -vfk ${proxy.sandbox_endpoint}/beer -H 'api-key: ${testUserKey}'
  curl -vfk ${proxy.sandbox_endpoint}/beer/Weissbier -H 'api-key: ${testUserKey}'
  curl -vfk ${proxy.sandbox_endpoint}/beer/findByStatus/available -H 'api-key: ${testUserKey}'
  """
}
    Copy to Clipboard Toggle word wrap

  6. Add a stage that uses the toolbox to promote the API to your production environment. 

    stage("Promote to production") {
  runToolbox([ "3scale", "proxy", "promote", targetInstance,  targetSystemName ])
}
    Copy to Clipboard Toggle word wrap

Additional resources

As a Red Hat 3scale API Management administrator, you can use the 3scale operator to configure 3scale services and provision 3scale resources. You use the operator in the OpenShift Container Platform (OCP) user interface. Using the operator is an alternative to configuring and provisioning 3scale in the Admin Portal or by using the 3scale internal API.

When you use the 3scale operator to configure a service or provision a resource the only way to update that service or resource is to update its custom resource (CR).

Note

In the Admin Portal, services and resources are visible, but do not make updates there. Likewise, do not make updates using the internal 3scale API to update services and resources. Making updates using methods other than a CR will cause the operator to revert changes, keeping the configuration unchanged.

This chapter includes details about how operator application capabilities work and how to use the operator to deploy custom resources:

Additionally, there is information about the limitations of capabilities when using the 3scale operator.

8.1. General prerequisites
Copy link

To configure and provision 3scale by using the 3scale operator, these are the required elements:

The 3scale operator contains these featured capabilities:

  • Allows interaction with the underlying Red Hat 3scale API Management solution.
  • Manages the 3scale application declaratively using custom resources from OpenShift.

The diagram below shows 3scale entities and relations that are eligible for management using OpenShift custom resources in a declarative way. Products contain one or more backends. At the product level, you can configure applications, application plans, as well as mapping rules. At the backend level, you can set up metrics, methods and mapping rules for each backend.

3scale entities and relations eligible for management using OpenShift custom resources.

3scale entities and relations eligible for management using OpenShift custom resources.

The 3scale operator provides custom resource definitions and their relations, which are visible in the following diagram.

3scale entities and relations eligible for management using OpenShift custom resources.

Using OpenShift Container Platform (OCP) in your newly created tenant, you will deploy your first 3scale product and backend with the minimum required configuration.

Prerequisites

The same installation requirements as listed in General prerequisites, with these considerations:

  • The 3scale account can be local in the working OpenShift namespace or a remote installation.
  • The required parameters from this account are the 3scale Admin Portal URL address and the access token.

Procedure

  1. Create a secret for the 3scale provider account using the credentials from the 3scale Admin Portal. For example: adminURL=https://3scale-admin.example.com and token=123456. 

    $ oc create secret generic threescale-provider-account --from-literal=adminURL=https://3scale-admin.example.com --from-literal=token=123456
    Copy to Clipboard Toggle word wrap

  2. Configure the 3scale backend with the upstream API URL:

    1. Create a YAML file with the following content: 

      apiVersion: capabilities.3scale.net/v1beta1
kind: Backend
metadata:
  name: backend1
spec:
  name: "Operated Backend 1"
  systemName: "backend1"
  privateBaseURL: "https://api.example.com"
      Copy to Clipboard Toggle word wrap

    2. Create a custom resource: 

      $ oc create -f backend1.yaml
      Copy to Clipboard Toggle word wrap

  3. Configure the 3scale product:

    1. Create a product with all the default settings applied to the previously created backend: 

      apiVersion: capabilities.3scale.net/v1beta1
kind: Product
metadata:
  name: product1
spec:
  name: "OperatedProduct 1"
  systemName: "operatedproduct1"
  backendUsages:
    backend1:
      path: /
      Copy to Clipboard Toggle word wrap
      • Once you create the file, the operator will confirm if the step was successful.
      • For more details about the fields of the Product CR and possible values, see the Product CRD Reference.

    2. Create a custom resource: 

      $ oc create -f product1.yaml
      Copy to Clipboard Toggle word wrap

      Additionally, you can update an existing product CRD to link to a backend: 

      $ oc apply -f product.yaml
      Copy to Clipboard Toggle word wrap

  4. Created custom resources will take a few seconds to populate your 3scale instance. To confirm when resources are synchronized, you can choose one of these alternatives:

    • Verify the status field of the object.

    • Use the oc wait commands: 

      $ oc wait --for=condition=Synced --timeout=-1s backend/backend1

$ oc wait --for=condition=Synced --timeout=-1s product/product1
      Copy to Clipboard Toggle word wrap

8.4. Promoting a product’s APIcast configuration
Copy link

Using the 3scale operator, you can promote the product’s APIcast configuration to staging or production. The ProxyConfigPromote custom resource (CR) promotes the latest APIcast configuration to the staging environment. Optionally, you can configure the ProxyConfigPromote CR to promote to the production environment as well.

Note
  • ProxyConfigPromote objects only take effect when created. After creation, any updates on them are not reconciled.
  • proxyConfigPromote only processes the promotion of configurations if there are actual configuration changes. If no changes are detected, proxyConfigPromote will enter an error state. In this state, an error message will be displayed on the Custom Resource (CR), and the user must manually remove the CR, even if it is marked for deletion.

Prerequisites

The same installation requirements as listed in General prerequisites, including:

Procedure

  1. Create and save a YAML file with the following content: 

    apiVersion: capabilities.3scale.net/v1beta1
kind: ProxyConfigPromote
metadata:
  name: proxyconfigpromote-sample
spec:
  productCRName: product1-sample
    Copy to Clipboard Toggle word wrap

    To promote the APIcast configuration to the production environment, set the optional field spec.production to true: 

    apiVersion: capabilities.3scale.net/v1beta1
kind: ProxyConfigPromote
metadata:
  name: proxyconfigpromote-sample
spec:
  productCRName: product1-sample
  production: true
    Copy to Clipboard Toggle word wrap

    To delete the ProxyConfigPromote object after a successful promotion, set the optional field spec.deleteCR to true: 

    apiVersion: capabilities.3scale.net/v1beta1
kind: ProxyConfigPromote
metadata:
  name: proxyconfigpromote-sample
spec:
  productCRName: product1-sample
  deleteCR: true
    Copy to Clipboard Toggle word wrap

  2. To check the status condition of the file, type the following command: 

    $ oc get proxyconfigpromote proxyconfigpromote-sample -o yaml
    Copy to Clipboard Toggle word wrap

    1. The output should show the status is Ready or Failed: 

      apiVersion: capabilities.3scale.net/v1beta1
kind: ProxyConfigPromote
metadata:
  name: proxyconfigpromote-sample
spec:
  productCRName: product1-sample
status:
  conditions:
    - lastTransitionTime: '2023-09-05T07:15:11Z'
      message: >-
        3scale product has been successfully promoted, any further interactions
        with this CR (apart from deletion) won't be applied
      status: 'True'
      type: Ready
  latestStagingVersion: 1
  productId: '7'
      Copy to Clipboard Toggle word wrap 
      apiVersion: capabilities.3scale.net/v1beta1
kind: ProxyConfigPromote
metadata:
  name: proxyconfigpromote-sample
spec:
  productCRName: product1-sample
status:
  conditions:
    - lastTransitionTime: '2023-09-05T07:48:08Z'
      message: >-
        cannot promote to production as no product changes detected. Delete this
        proxyConfigPromote CR, then introduce changes to configuration, and then
        create a new proxyConfigPromote CR
      status: 'True'
      type: Failed
  latestProductionVersion: 1
  latestStagingVersion: 1
  productId: '6'
      Copy to Clipboard Toggle word wrap
      Note

      If you do not make changes in the proxy configuration, you get a Failed output status of the ProxyConfigPromote CR with one the following messages:

      • When promoting to stage: cannot promote to staging as no product changes detected. Delete this proxyConfigPromote CR, then introduce changes to configuration, and then create a new proxyConfigPromote CR.
      • When promoting to production: cannot promote to production as no product changes detected. Delete this proxyConfigPromote CR, then introduce changes to configuration, and then create a new proxyConfigPromote CR.

      Follow the instruction in the message to complete your procedure.

  3. Create the custom resource: 

    oc create -f proxyconfigpromote-sample.yaml
    Copy to Clipboard Toggle word wrap

    • For the given example, the output would be: 

      proxyconfigpromote.capabilities.3scale.net/proxyconfigpromote-sample created
      Copy to Clipboard Toggle word wrap

Additional resources

An OpenAPI custom resource (CR) is one way to import an OpenAPI Specification (OAS) document that you can use for ActiveDocs in the Developer Portal. The OAS is a standard that does not tie you to using one particular programming language for your APIs. Humans and computers can more easily understand the capabilities of the API product without source code access, documentation, or network traffic inspection.

Prerequisites

  • A user account with administrator privileges for a 3scale 2.15 On-Premises instance.
  • An OAS document that defines your API.
  • An understanding of how an OpenAPI CR links to a tenant.
  • apiKey and openIdConnect/oauth2 are the supported security schemes.

OpenID Connect and OAuth2 limitations

To configure 3scale in the OpenAPI specification, you must provide the following data in the OpenAPI custom resource (CR):

  • OpenID Connect (OIDC) issuerType:

    • Define the issuer type, which defaults to rest. You can override this parameter in the OpenAPI CR.

  • Define the issuerEndpoint, as a plain value URL, or the issuerEndpointRef secret with the issuerEndpoint URL.

  • Flows Object:

    • When you define the oauth2 security scheme, the OpenAPI document includes the flows. However, when the security scheme is OpenID Connect, the OpenAPI document does not provide the flows. In this case, the OpenAPI CR can provide them.

Deploy an OpenAPI custom resource (CR) so that you can create 3scale backends and products.

Note

The operator reads only the content in the secret. The operator does not read the field name in the secret.

Prerequisites

You understand How the 3scale operator identifies the tenant that a custom resource links to.

Procedure

  1. Define a secret that contains an OAS document. For example, you might create the myoasdoc1.yaml with this content: 

    openapi: "3.0.2"
info:
  title: "some title"
  description: "some description"
  version: "1.0.0"
paths:
  /pet:
    get:
      operationId: "getPet"
      responses:
        405:
          description: "invalid input"
    Copy to Clipboard Toggle word wrap

  2. Create the secret. For example: 

    $ oc create secret generic myoasdoc1 --from-file myoasdoc1.yaml

secret/myoasdoc1 created
    Copy to Clipboard Toggle word wrap

  3. Define your OpenAPI CR. Be sure to specify a reference to the secret that contains your OAS document. For example, you might create the myopenapicr1.yaml file: 

    apiVersion: capabilities.3scale.net/v1beta1
kind: OpenAPI
metadata:
  name: myopenapicr1
spec:
  openapiRef:
    secretRef:
      name: myoasdoc1
    Copy to Clipboard Toggle word wrap

  4. Create the resource you just defined. For example: 

    $ oc create -f myopenapicr1.yaml
    Copy to Clipboard Toggle word wrap

    For the given example, the output would be: 

    $ openapi.capabilities.3scale.net/myopenapicr1 created
    Copy to Clipboard Toggle word wrap

Knowledge of the OpenAPI custom resource definition (CRD) deployment features will help you with configuration of the 3scale product, backend, and the subsequent creation of ActiveDocs for the Developer Portal.

  • The OAS document can be read from the following:

    • The Kubernetes secret.
    • The URL in both http and https formats.
  • In an OAS document, the info.title setting must not exceed 215 characters. The operator uses this setting to create OpenShift object names, which have length limitations.
  • Only the first servers[0].url element in a server list is parsed as a private URL. The OpenAPI Specification (OAS) uses its basePath component of servers[0].url element.
  • The OpenAPI CRD supports a single top level security requirement, however it does not support operational level security.
  • The OpenAPI CRD supports the apiKey and the openIdConnect/oauth2 security schemes.

Additional resources

The import rules specify how the OpenAPI Specification (OAS) works with 3scale when you are setting up an OpenAPI document for your 3scale deployment.

Product name

The default product system name is taken from the info.title field in the OpenAPI document. To override the product name in an OpenAPI document, specify the spec.productSystemName field in an OpenAPI custom resource (CR).

Private base URL

The private base URL is read from the OpenAPI CR servers[0].url field. You can override this by using the spec.privateBaseURL field in your OpenAPI CR.

3scale methods

Each operation that is defined in the imported OpenAPI document translates to one 3scale method at the product level. The method name is read from the operationId field of the operation object.

3scale mapping rules

Each operation that is defined in the imported OpenAPI document translates to one 3scale mapping rule at the product level. Previously existing mapping rules are replaced by those imported with the OpenAPI CR.

In an OpenAPI document, the paths object provides mapping rules for verb and pattern properties. 3scale methods are associated accordingly to the operationId.

The delta value is hard-coded to 1.

By default, Strict matching policy is configured. Matching policy can be switched to Prefix matching using the spec.PrefixMatching field of the OpenAPI CRD.

Authentication

Just one top level security requirement is supported. Operation level security requirements are not supported.

The supported security scheme is apiKey.

The apiKey security scheme type:

  • credentials location will be read from the OpenAPI document in field of the security scheme object.
  • Auth user key will be read from the OpenAPI document name field of the security scheme object.

The following is a partial example of OAS 3.0.2 with apiKey security requirement: 

openapi: "3.0.2"
security:
  - petstore_api_key: []
components:
  securitySchemes:
    petstore_api_key:
      type: apiKey
      name: api_key
      in: header
Copy to Clipboard Toggle word wrap

When the OpenAPI document does not specify any security requirements, the following applies:

  • The product authentication will be configured for apiKey.
  • credentials location will default to 3scale value As query parameters (GET) or body parameters (POST/PUT/DELETE).
  • The Auth user key defaults to 3scale value user_key.

3scale Authentication Security can be set using the spec.privateAPIHostHeader and the spec.privateAPISecretToken fields of the OpenAPI CRD.

ActiveDocs

No 3scale ActiveDoc is created.

3scale product policy chain

The 3scale policy chain is the default one 3scale creates.

3scale deployment mode

By default, the configured 3scale deployment mode will be APIcast 3scale managed. However, when the spec.productionPublicBaseURL or the spec.stagingPublicBaseURL, or both fields are present in an OpenAPI CR, the product’s deployment mode is APIcast self-managed.

Example of a OpenAPI CR with custom public base URL: 

apiVersion: capabilities.3scale.net/v1beta1
kind: OpenAPI
metadata:
  name: openapi1
spec:
  openapiRef:
    url: "https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml"
  productionPublicBaseURL: "https://production.my-gateway.example.com"
  stagingPublicBaseURL: "https://staging.my-gateway.example.com"
Copy to Clipboard Toggle word wrap

8.6.4. Configuring OpenID Connect and OAuth2
Copy link

Red Hat 3scale API Management requires additional information not included in the OpenAPI Specification (OAS). You must provide this information in the OpenAPI custom resource (CR), specifically the following:

  • OpenID Connect Issuer Type

    Defaults to rest, but it can be overridden from the OpenAPI CR.

  • OpenID Connect Issuer Endpoint Reference (Secret)

    3scale requires that the issuer URL includes a client secret.

  • Flows object

    When the security scheme is OAuth2, the flows are provided by the OpenAPI document. However, for the OpenID Connect (OIDC) security scheme, the OpenAPI document does not provide the flows.

    There are 4 flows parameters for OIDC only:

    • standardFlowEnabled
    • implicitFlowEnabled
    • serviceAccountsEnabled
    • directAccessGrantsEnabled.

OIDC issuer secret

  • You have previously setup Issuer Client. RHSSO/keycloak realm and client are using it in the secret example.
  • issuerEndpoint format is https://<client-id>:<client-secret>@<host>:<port>/auth/realms/<realm-name>. The format is described in the 3scale Portal/Products page - AUTHENTICATION SETTINGS - OpenID Connect Issuer.
  • The <client-secret> value is taken from the Issuer Client in Realm/Clients/ClientID/Credentials/Secret.

Procedure

  1. Create the secret, for example, my-secret.yaml, with the following content: 

    kind: Secret
apiVersion: v1
metadata:
  name: my-secret
  namespace: 3scale-test
data:
  issuerEndpoint: https://3scale-zync:some-secret@keycloak-rhsso-test.example.com/auth/realms/petstore
type: Opaque
    Copy to Clipboard Toggle word wrap

  2. Apply the secret with the following command: 

    $ oc apply -f my-secret.yaml
    Copy to Clipboard Toggle word wrap

  3. Create the OpenAPI CR for OIDC and OAuth2, for example, openapi-example.yaml, with the following content: 

    apiVersion: capabilities.3scale.net/v1beta1
kind: OpenAPI
metadata:
  generation: 1
  name: openapi-example
spec:
  openapiRef:
    url: "https://example.com/petstore.yaml"
  privateAPISecretToken: "xxxx"
  oidc:
    issuerType: keycloak
    issuerEndpointRef:
      name: my-secret
    jwtClaimWithClientID: azp
    jwtClaimWithClientIDType: plain
    authenticationFlow:
      standardFlowEnabled: true
      implicitFlowEnabled: true
      serviceAccountsEnabled: true
      directAccessGrantsEnabled: true
    gatewayResponse:
      errorStatusAuthFailed: 403
    Copy to Clipboard Toggle word wrap

  4. Apply the OpenAPI CR for OIDC and OAuth2 with the following command: 

    $ oc apply -f <openapi-cr-file>.yaml
    Copy to Clipboard Toggle word wrap
Note
  • The OIDC field is optional in the OpenAPI CR, applicable only for OpenID Connect.
  • issuerEndpointRef should reference a secret containing the issuerEndpoint

Table 8.1. OIDC specification field description

Field

Required

Description

issuerType

no

Valid values: [keycloak, rest]. Defaults to rest.

issuerEndpoint

no

issuerEndpoint can be defined in issuerEndpointRef or as plain value. The format of this endpoint is determined on your OpenID provider setup. For Red Hat single sign-on: https://<client-id>:<client-secret>@<host>:<port>/auth/realms/<realm-name>

issuerEndpointRef

no

The secret that contains issuerEndpoint.

jwtClaimWithClientID

no

JSON Web Token (JWT) Claim with ClientID that contains the clientID. Defaults to azp.

jwtClaimWithClientIDType

no

jwtClaimWithClientIDType sets to process the ClientID Token Claim value as a string or as a liquid template. Valid values: plain, liquid. Defaults to plain.

authenticationFlow

no

Flows object: When the security scheme is OAuth2, the flows are provided by the OpenAPI document. However, for the OIDC security scheme, the OpenAPI document does not provide the flows. In that case, the OpenAPI CR can provide those. There are 4 flows parameters for OIDC only: standardFlowEnabled, implicitFlowEnabled, serviceAccountsEnabled, directAccessGrantsEnabled.

gatewayResponse

no

Specifies custom gateway response on errors. See GatewayResponseSpec.

  • Define the issuerEndpointRef or issuerEndpoint in OIDC specification, however you can define both fields.
  • If issuerEndpoint plain value is defined in the CR, it will be used as precedence over issuerEndpointRef secret.

  • The format of issuerEndpoint is determined on your OpenID Provider setup:

    • In the 3scale Admin Portal, navigate to [Your_product_name] > Integration > Settings. Under Authentication, click the OpenID Connect Issuer option. Check the OpenID Connect Issuer Type.

      • The following is an OpenAPI CR example where issuerEndpoint is defined both as plain value and in secret. The plain value is used: 

        apiVersion: capabilities.3scale.net/v1beta1
kind: OpenAPI
metadata:
  generation: 1
  name: openapi-example
spec:
  openapiRef:
    url: "https://example.com/petstore.yaml"
  oidc:
    issuerType: keycloak
    issuerEndpoint: https://3scale-zync:some-secret@keycloak-rhsso-test.example.com/auth/realms/petstore
    issuerEndpointRef:
      name: my-secret
    jwtClaimWithClientID: azp
    jwtClaimWithClientIDType: plain
    authenticationFlow:
      standardFlowEnabled: true
      implicitFlowEnabled: true
      serviceAccountsEnabled: true
      directAccessGrantsEnabled: true
        Copy to Clipboard Toggle word wrap

  • If the OpenAPI CR specification is OIDC, but the securitySchemes type in OAS is oauth2, then the CR OIDC Authentication Flows parameters will be ignored, and Product OIDC Authentication Flows will be set to match oauth2 flows as defined in OAS:

    • standardFlowEnabled is true if OAuth2 authorizationCode is defined
    • implicitFlowEnabled is true if OAuth2 implicit is defined
    • serviceAccountsEnabled is true if OAuth2 clientCredentials is defined

    • directAccessGrantsEnabled is true if OAuth2 password is defined

      An example of OAS securitySchemes definition that allows selection of all Product OIDC Authentication Flows. Note: Define OIDC in the OpenAPI CR: 

      securitySchemes:
  myOauth:

Additional resources

You can deploy an OpenAPI custom resource that imports an OAS document from a URL that you specify. You can then use this OAS document as the foundation for ActiveDocs for your API in the Developer Portal.

Prerequisites

  • If you are creating an OpenAPI custom resource that does not link to the default tenant in the 3scale instance that is in the same namespace then the namespace that will contain the OpenAPI CR contains a secret that identifies the tenant that the OpenAPI CR links to. The name of the secret is one of the following:

    • threescale-provider-account
    • User defined

    This secret contains the URL for a 3scale instance and a token that contains credentials for access to one tenant in that 3scale instance.

Procedure

  1. In your OpenShift account, navigate to Operators > Installed operators.
  2. Click the 3scale operator.
  3. Choose the YAML tab.

  4. Create an OpenAPI custom resource (CR). For example: 

    apiVersion: capabilities.3scale.net/v1beta1
kind: OpenAPI
metadata:
  name: openapi1
spec:
  openapiRef:
    url: "https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml"
  providerAccountRef:
    name: mytenant
    Copy to Clipboard Toggle word wrap
  5. Click Save. It takes a few seconds for the 3scale operator to create the OpenAPI CR.

Verification

  1. In OpenShift, in the 3scale Product Overview page, confirm that the Synced condition is marked as True.
  2. Go to your 3scale account.
  3. Confirm that the OAS document is present. For the example above, you would see a new OAS document named openapi1.

Red Hat 3scale API Management ActiveDocs are based on API definition documents that define RESTful web services that conform to the OpenAPI Specification. An ActiveDoc custom resource (CR) is one way to import an OpenAPI Specification (OAS) document that you can use for ActiveDocs in the Developer Portal. The OAS is a standard that does not tie you to using one particular programming language for your APIs. Humans and computers can more easily understand the capabilities of the API product without source code access, documentation, or network traffic inspection.

Prerequisites

  • A user account with administrator privileges for a 3scale 2.15 On-Premises instance.

  • An OAS document that defines your API.

    • OAS 3.0.2 is the only supported version with the ActiveDocs custom resource definition (CRD).
  • An understanding of how an ActiveDoc CR links to a tenant.

Deploy an ActiveDoc custom resource (CR) so that you can create 3scale backends and products.

Note

The operator reads only the content in the secret. The operator does not read the field name in the secret. For example, data is structured in key: value pairs, where value represents the content of a file and key is the file name. The file name is ignored by the operator in this context of ActiveDoc CRD. The operator reads only the content of the file.

Prerequisites

  • You understand How the 3scale API Management operator identifies the tenant that a custom resource links to.

  • Define a secret that contains an OAS (OpenAPI Specification) document. For example, you might create the myoasdoc1.yaml with this content: 

    openapi: "3.0.2"
info:
  title: "some title"
  description: "some description"
  version: "1.0.0"
paths:
  /pet:
    get:
      operationId: "getPet"
      responses:
        405:
          description: "invalid input"
    Copy to Clipboard Toggle word wrap

Procedure

  1. Create the secret. For example: 

    $ oc create secret generic myoasdoc1 --from-file myoasdoc1.yaml

secret/myoasdoc1 created
    Copy to Clipboard Toggle word wrap

  2. Define your ActiveDoc CR. Be sure to specify a reference to the secret that contains your OAS document. For example, you might create the myactivedoccr1.yaml file: 

    apiVersion: capabilities.3scale.net/v1beta1
kind: ActiveDoc
metadata:
  name: myactivedoccr1
spec:
  name: "Operated ActiveDoc From secret"
  activeDocOpenAPIRef:
    secretRef:
      name: myoasdoc1
    Copy to Clipboard Toggle word wrap

  3. Create the resource you just defined. For example: 

    $ oc create -f myactivedoccr1.yaml
    Copy to Clipboard Toggle word wrap

    For the given example, the output would be: 

    $ activedoc.capabilities.3scale.net/myactivedoccr1 created
    Copy to Clipboard Toggle word wrap

Verification

  1. Log in to your Red Hat OpenShift Container Platform (OCP) administrator account.
  2. Navigate to Operators > Installed Operators.
  3. Click Red Hat Integration - 3scale.
  4. Click the Active Doc tab.
  5. Confirm that the OAS document is present. For the example above, you would see a new OAS document named myactivedoccr1.

The ActiveDoc custom resource definition (CRD) concerns product documentation in the OpenAPI document format for developers. Knowledge of the ActiveDoc CRD deployment features help you with the creation of ActiveDocs for the Developer Portal.

  • An ActiveDoc CR, can read and OpenAPI document from either of the following:

    • Secret.
    • A URL in either http or https format
  • Optionally, you can link the ActiveDoc CR with a 3scale product using the productSystemName field. The value must be the system_name of the 3scale product’s CR.
  • You can publish or hide the ActiveDoc document in 3scale using the published field. By default, this is set to be hidden.
  • You can skip OpenAPI 3.0 validation using the skipSwaggerValidations field. By default, the ActiveDoc CR is validated.

Additional resources

You can deploy an ActiveDoc custom resource (CR) that imports an OAS (OpenAPI Specification) document from a URL that you specify. You can then use this OAS document as the foundation for ActiveDocs for your API in the Developer Portal.

Prerequisites

Procedure

  1. In your OpenShift account, navigate to Operators > Installed operators.
  2. Click the 3scale operator.
  3. Click the Active Doc tab.

  4. Create an ActiveDoc CR. For example: 

    apiVersion: capabilities.3scale.net/v1beta1
kind: ActiveDoc
metadata:
  name: myactivedoccr1
spec:
  openapiRef:
    url: "https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml"
  providerAccountRef:
    name: mytenant
    Copy to Clipboard Toggle word wrap

  5. Optional. For self-managed APIcast, in the ActiveDoc CR, set the productionPublicBaseURL and stagingPublicBaseURL fields to the URLs for your deployment. For example: 

    apiVersion: capabilities.3scale.net/v1beta1
kind: ActiveDoc
metadata:
  name: myactivedoccr1
spec:
  openapiRef:
    url: "https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml"
  productionPublicBaseURL: "https://production.my-gateway.example.com"
  stagingPublicBaseURL: "https://staging.my-gateway.example.com"
    Copy to Clipboard Toggle word wrap
  6. Click Save. It takes a few seconds for the 3scale operator to create the ActiveDoc CR.

Verification

  1. Log in to your Red Hat OpenShift Container Platform (OCP) administrator account.
  2. Navigate to Operators > Installed Operators.
  3. Click Red Hat Integration 3scale.
  4. Click the Active Doc tab.
  5. Confirm that the OAS document is present. For the example above, you would see a new OAS document named myactivedoccr1.

You can use a CustomPolicyDefinition custom resource definition (CRD) to configure your custom policy in a 3scale product from the Admin Portal.

When the 3scale operator finds a new CustomPolicyDefinition custom resource (CR), the operator identifies the tenant that owns the CR as described in How the 3scale API Management operator identifies the tenant that a custom resource links to.

Prerequisites

Procedure

  1. Define a CustomPolicyDefinition CR and save it in, for example, the my-apicast-custom-policy-definition.yaml file: 

    apiVersion: capabilities.3scale.net/v1beta1
kind: CustomPolicyDefinition
metadata:
  name: custompolicydefinition-sample
spec:
  version: "0.1"
  name: "APIcast Example Policy"
  schema:
    name: "APIcast Example Policy"
    version: "0.1"
    $schema: "http://apicast.io/policy-v1/schema#manifest#"
    summary: "This is just an example."
    configuration:
      type: object
      properties: {}

8.12. Deploying a tenant custom resource
Copy link

A Tenant custom resource (CR) is also known as the Provider Account.

When you deploy an APIManager CR you are using the 3scale operator to deploy 3scale. A default 3scale installation includes a default tenant ready to be used. Optionally, you can create other tenants by deploying Tenant CR.

Prerequisites

Procedure

  1. Navigate to the OpenShift project in which 3scale is installed. For example, if the name of the project is my-3scale-project, run the following command: 

    $ oc project my-3scale-project
    Copy to Clipboard Toggle word wrap

  2. Create a secret that contains the password for the 3scale admin account for the new tenant. In the definition of the Tenant CR, set the passwordCredentialsRef attribute to the name of this secret. In the example of a Tenant CR definition in step 4, ADMIN_SECRET is the placeholder for this secret. The following command provides an example of creating the secret: 

    $ oc create secret generic ecorp-admin-secret --from-literal=admin_password=<admin password value>
    Copy to Clipboard Toggle word wrap

  3. Obtain the 3scale master account hostname. When you deploy 3scale by using the operator, the master account has a fixed URL with this pattern: master.${wildcardDomain}

    If you have access to the namespace where 3scale is installed, you can obtain the master account hostname with this command: 

    $ oc get routes --field-selector=spec.to.name==system-master -o jsonpath="{.items[].spec.host}"
    Copy to Clipboard Toggle word wrap

    In the example of a Tenant CR definition in step 4, MASTER_HOSTNAME is the placeholder for this name.

  4. Create a file that defines the new Tenant CR.

    In the definition of the Tenant CR, set the masterCredentialsRef.name attribute to system-seed. You can perform tenant management tasks only by using the 3scale master account credentials, preferably an access token. During deployment of an APIManager CR, the operator creates the secret that contains master account credentials. The name of the secret is system-seed.

    If 3scale is installed in cluster wide mode, you can deploy the new tenant in a namespace that is different from the namespace that contains 3scale. To do this, set masterCredentialsRef.namespace to the namespace that contains the 3scale installation.

    The following example assumes that 3scale is installed in cluster wide mode. 

    apiVersion: capabilities.3scale.net/v1alpha1
kind: Tenant
metadata:
  generation: 3
  name: <ecorp_tenant>
  namespace: <namespace_in_which_to_create_tenant-CR>
spec:
  email: admin@ecorp.com
  masterCredentialsRef:
    name: system-seed
    namespace: <namespace-where-3scale-is-deployed>
  organizationName: ECorp
  passwordCredentialsRef:
    name: <admin_secret>
    namespace: <namespace_in_which_to_create_tenant-CR>
  systemMasterUrl: https://<master_hostname>
  tenantSecretRef:
    name: <tenant_secret>
    namespace: <namespace_in_which_to_create_tenant-CR>
  username: tenant2FromCR1
    Copy to Clipboard Toggle word wrap

  5. Create the Tenant CR. For example, if you saved the previous example CR in the mytenant.yaml file, you would run: 

    $ oc create -f mytenant.yaml
    Copy to Clipboard Toggle word wrap

    As a result of this command:

    • The operator deploys a tenant in the 3scale installation pointed to by the setting of the spec.systemMasterUrl attribute.

    • The 3scale operator creates a secret that contains credentials for the new tenant. The name of the secret is the value you specified for the tenantSecretRef.name attribute. This secret contains the new tenant`s admin URL and access token.

      As a reference, this is an example of the secret that the operator creates: 

      apiVersion: v1
kind: Secret
metadata:
  name: <tenant_secret>
type: Opaque
stringData:
  adminURL: https://my3scale-admin.example.com:443
  token: "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
      Copy to Clipboard Toggle word wrap
    • You can now deploy Product, Backend, OpenAPI, DeveloperAccount, and DeveloperUser CRs that link to your new tenant.

Extending the capabilities of a Tenant CR

You can set the following optional parameters in your 3scale Tenant via the Tenant CR:

  • fromEmail
  • supportEmail
  • financeSupportEmail
  • siteAccessCode

Procedure

  1. Update the tenant info parameters in your 3scale Tenant via the Tenant CR: 

    apiVersion: capabilities.3scale.net/v1alpha1
kind: Tenant
metadata:
  generation: 3
  name: <ecorp_tenant>
  namespace: <namespace_in_which_to_create_tenant-CR>
spec:
  email: admin@ecorp.com
  masterCredentialsRef:
    name: system-seed
    namespace: <namespace-where-3scale-is-deployed>
  organizationName: ECorp
  passwordCredentialsRef:
    name: <admin_secret>
    namespace: <namespace_in_which_to_create_tenant-CR>
  systemMasterUrl: https://<master_hostname>
  tenantSecretRef:
    name: <tenant_secret>
    namespace: <namespace_in_which_to_create_tenant-CR>
  username: <tenant2FromCR1>
  fromEmail: <tenant2FromCR1>@ecorp.com
  supportEmail: <tenant2Support>@ecorp.com
  financeSupportEmail: <tenant2FinanceSupport>@ecorp.com
  siteAccessCode: <abc123>
    Copy to Clipboard Toggle word wrap

  2. Apply the change to the Tenant CR: 

    $ oc apply -f mytenant.yaml
    Copy to Clipboard Toggle word wrap
Deleting a Tenant CR

Do not delete a tenant in the Admin Portal if you deployed that tenant with a Tenant CR. If you do, the operator creates another tenant by using the CR for the tenant that you tried to delete.

To delete a deployed Tenant CR, you can specify the name of the file that contains the resource definition, for example: 

$ oc delete -f mytenant.yaml
Copy to Clipboard Toggle word wrap

Alternatively, you can run the oc delete command, specify the name in the Tenant CR and also specify the tenant’s namespace. For example: 

$ oc delete tenant.capabilities.3scale.net mytenant -n mynamespace
Copy to Clipboard Toggle word wrap

When you delete a tenant, the 3scale operator does the following:

  • Hides the tenant from the 3scale installation.
  • Deletes the deployed CRs that the tenant owns.
  • Marks the tenant to be deleted after 15 days.

After you delete a tenant, you cannot recover it. You have 15 days to back up any resources that the tenant owned and you can do this only in the Admin Portal. After 15 days, 3scale deletes the tenant. To comply with data protection laws, some data is kept for future reference.

Additional resources

As a 3scale administrator, you can use custom resources (CRs) to deploy developer accounts that group together individual developer users. These accounts let you organize and manage developer access to 3scale-managed APIs in the Developer Portal.

A tenant can contain any number of developer accounts and each developer account links to exactly one tenant. A developer account can contain any number of developer users and each developer user links to exactly one developer account. The tenant plan determines any limits on how many developer accounts you can create and how many developer users can be grouped in each developer account.

To use developer custom resources, 3scale must have been installed by the 3scale operator. You can deploy developer custom resources in only the namespace that contains the 3scale operator. Deployment of developer custom resources is an alternative to managing developers by using the 3scale Admin Portal or the 3scale internal API.

Important

When you create developer accounts or developer users by deploying custom resources you cannot use the Admin Portal or the internal 3scale API to update those developer accounts or developer users. It is important to be aware of this because after you deploy a developer CR, the Admin Portal displays the new developer account or new developer user in its Accounts page. If you try to use the Admin Portal or API to update a developer account or developer user that was deployed with a CR, the 3scale operator reverts the changes to reflect the deployed CR. This is a limitation that is expected to be removed in a future release. You can, however, use the Admin Portal or API to delete a developer account or developer user that you created by deploying a CR.

8.13.1. Prerequisites
Copy link

  • 3scale was installed by the 3scale operator.
  • Access token with read and write permissions in the Account Management API scope, which provides administrator privileges for 3scale.

When you use the 3scale operator to install 3scale you can deploy DeveloperAccount and DeveloperUser custom resources (CRs). These custom resources let you create and update accounts for developer access to 3scale-managed APIs in the Developer Portal.

To deploy a new DeveloperAccount CR, you must also deploy a DeveloperUser CR for a user who has the admin role. The procedure provided here is for deploying a new DeveloperAccount CR. After you deploy a DeveloperAccount CR, the procedure for updating or deleting it is the same as for any other CR.

You can deploy custom resources only in the namespace that contains the 3scale operator.

Prerequisites

  • An understanding of how the 3scale API Management operator identifies the tenant that a custom resource links to.

  • If you are creating a DeveloperAccount CR that does not link to the default tenant in the 3scale instance that is in the same namespace, then the namespace that will contain the DeveloperAccount CR contains a secret that identifies the tenant that the DeveloperAccount CR links to. The name of the secret is one of the following:

    • threescale-provider-account
    • User defined

    This secret contains the URL for a 3scale instance and a token that contains credentials for access to one tenant in that 3scale instance.

  • You have the username, password, and email address for at least one developer user who will have the admin role in the new DeveloperAccount CR.

Procedure

  1. In the namespace that contains the 3scale operator, create and save a resource file that defines a secret that contains the user name and password for a developer user who will have the admin role in the new developer account resource. For example, the myusername01.yaml file might contain: 

    apiVersion: v1
kind: Secret
metadata:
  name: myusername01
stringData:
  password: "123456"
    Copy to Clipboard Toggle word wrap

  2. Create the secret. For example: 

    $ oc create -f myusername01.yaml
    Copy to Clipboard Toggle word wrap

    For the given example, the output would be: 

    $ secret/myusername01 created
    Copy to Clipboard Toggle word wrap

  3. Create and save a .yaml file that defines a DeveloperUser CR for a developer who has the admin role. This DeveloperUser CR is required for the 3scale operator to deploy a new DeveloperAccount CR. For example, the developeruser01.yaml file might contain: 

    apiVersion: capabilities.3scale.net/v1beta1
kind: DeveloperUser
metadata:
  name: developeruser01
spec:
  username: myusername01
  email: myusername01@example.com
  passwordCredentialsRef:
    name: myusername01
  role: admin
  developerAccountRef:
    name: developeraccount1
  providerAccountRef:
    name: mytenant
    Copy to Clipboard Toggle word wrap

    In a DeveloperUser CR:

    • The developer user account name, user name, and email must be unique in the tenant that the containing DeveloperAccount links to.
    • The developer account name that you specify here must match the name of the DeveloperAccount CR that you are deploying in this procedure. It does not matter whether you create the DeveloperAccount CR before or after you create this DeveloperUser CR.
    • The tenant that a DeveloperUser CR links to must be the same tenant that the specified DeveloperAccount CR links to.

  4. Create the resource you just defined. For example: 

    $ oc create -f developeruser01.yaml
    Copy to Clipboard Toggle word wrap

    For the given example, the output would be: 

    $ developeruser.capabilities.3scale.net/developeruser01 created
    Copy to Clipboard Toggle word wrap

  5. Create and save a .yaml file that defines a DeveloperAccount CR. In this .yaml file, the spec.OrgName field must specify an organization name. For example, the developeraccount01.yaml file might contain: 

    apiVersion: capabilities.3scale.net/v1beta1
kind: DeveloperAccount
metadata:
  name: developeraccount01
spec:
  orgName: Ecorp
  providerAccountRef:
    name: mytenant
    Copy to Clipboard Toggle word wrap

  6. Create the resource you just defined. For example: 

    $ oc create -f developeraccount01.yaml
    Copy to Clipboard Toggle word wrap

    For the given example, the output would be: 

    $ developeraccount.capabilities.3scale.net/developeraccount01 created
    Copy to Clipboard Toggle word wrap

Next steps

It takes a few seconds for the 3scale operator to update the 3scale configuration to reflect new or updated custom resources. To check whether the operator is propagating custom resource information successfully, check the DeveloperAccount CR status field or run the oc wait command, for example: 

$ oc wait --for=condition=Ready --timeout=30s developeraccount/developeraccount1
Copy to Clipboard Toggle word wrap

In case of failure, the custom resource’s status field indicates if the error is transient or permanent, and provides an error message that helps fix the problem.

Notify any new developer users that they can log in to the Developer Portal. You might also need to communicate their log-in credentials.

You can update a deployed DeveloperAccount CR in the same way that you update any other custom resource. For example, in the OpenShift project that contains the tenant that owns the DeveloperAccount CR that you want to update, you would run the following command to update the devaccount1 CR: 

$ oc edit developeraccount devaccount1
Copy to Clipboard Toggle word wrap

When you use the 3scale operator to install 3scale you can deploy DeveloperUser custom resources (CRs) for managing developer access to 3scale-managed APIs in the Developer Portal. The procedure provided here is for deploying a new DeveloperUser CR. After you deploy a DeveloperUser CR, the procedure for updating or deleting it is the same as for any other CR.

You can deploy CRs only in the namespace that contains the 3scale operator.

Prerequisites

  • An understanding of how the 3scale operator identifies the tenant that a custom resource links to.

  • There is at least one deployed DeveloperAccount CR that contains at least one deployed DeveloperUser CR for a user who has the admin role. If you are creating a DeveloperUser CR that does not link to the default tenant in the 3scale instance that is in the same namespace, then the namespace that will contain the DeveloperUser CR contains a secret that identifies the tenant that the DeveloperUser CR links to. The name of the secret is one of the following:

    • threescale-provider-account
    • User defined

    This secret contains the URL for a 3scale instance and a token that contains credentials for access to one tenant in that 3scale instance.

  • For a new DeveloperUser CR, you have that developer’s username, password, and email address.

Procedure

  1. In the namespace that contains the 3scale operator, create and save a resource file that defines a secret that contains the username and password for a developer user. For example, the myusername02.yaml file might contain: 

    apiVersion: v1
kind: Secret
metadata:
  name: myusername02
stringData:
  password: "987654321"
    Copy to Clipboard Toggle word wrap

  2. Create the secret. For example: 

    $ oc create -f myusername02.yaml
    Copy to Clipboard Toggle word wrap

    For the given example, the output would be: 

    $ secret/myusername02 created
    Copy to Clipboard Toggle word wrap

  3. Create and save a .yaml file that defines a DeveloperUser CR. In the spec.role field, specify admin or member. For example, the developeruser02.yaml file might contain: 

    apiVersion: capabilities.3scale.net/v1beta1
kind: DeveloperUser
metadata:
  name: developeruser02
spec:
  username: myusername02
  email: myusername02@example.com
  passwordCredentialsRef:
    name: myusername02
  role: member
  developerAccountRef:
    name: developeraccount1
  providerAccountRef:
    name: mytenant
    Copy to Clipboard Toggle word wrap

    In a DeveloperUser CR:

    • The developer username (specified in the metadata.name field), the username, and email must be unique in the tenant that the containing DeveloperAccount links to.
    • The developerAccountRef field must specify the name of a deployed DeveloperAccount CR.
    • The tenant that a DeveloperUser CR links to must be the same tenant that the specified DeveloperAccount CR links to.

  4. Create the resource you just defined. For example: 

    $ oc create -f developefuser02.yaml
    Copy to Clipboard Toggle word wrap

    For the given example, the output would be: 

    $ developeruser.capabilities.3scale.net/developeruser02 created
    Copy to Clipboard Toggle word wrap

Next steps

It takes a few seconds for the 3scale operator to update the 3scale configuration to reflect new or updated custom resources. To check whether the operator is propagating custom resource information successfully, check the DeveloperUser CR status field or run the oc wait command, for example: 

$ oc wait --for=condition=Ready --timeout=30s developeruser/developeruser02
Copy to Clipboard Toggle word wrap

In case of failure, the custom resource’s status field indicates if the error is transient or permanent, and provides an error message that helps fix the problem.

Notify any new developer users that they can log in to the Developer Portal. You might also need to communicate their log-in credentials.

You can update a deployed DeveloperUser CR in the same way that you update any other custom resource.

You can delete a 3scale developer entity by deleting the custom resource (CR) that manages it. When you delete a DeveloperAccount CR the 3scale operator also deletes any DeveloperUser CRs that link to the deleted DeveloperAccount CR.

Important

The only way to delete a developer account or developer user defined by a custom resource is to follow the procedure described here. Do not use the Admin Portal nor the 3scale API to delete a developer entity that was deployed as a custom resource.

Prerequisites

  • 3scale administrator permissions or an OpenShift role that has delete permissions in the namespace that contains the custom resource you want to delete. To confirm that you can delete a particular custom resource, run the oc auth can-i delete command. For example, if the name in the DeveloperAccount CR is devaccount1, run this command: 

    $ oc auth can-i delete developeraccount.capabilities.3scale.net/devaccount1 -n my-namespace
    Copy to Clipboard Toggle word wrap
  • The DeveloperAccount or DeveloperUser CR to be deleted links to a valid tenant.

Procedure

  • In the OpenShift project that contains the tenant that the custom resource links to, run the oc delete command to delete a DeveloperAccount or DeveloperUser CR. For example, if you deployed a DeveloperAccount CR that was defined in the devaccount1.yaml file, you would run the following command: 

    $ oc delete -f devaccount1.yaml
    Copy to Clipboard Toggle word wrap

    Alternatively, you can run the oc delete command and specify the name of the CR as specified in its definition. For example: 

    $ oc delete developeraccount.capabilities.3scale.net/devaccount1
    Copy to Clipboard Toggle word wrap

In Red Hat 3scale API Management 2.15, 3scale operator contains these limitations with capabilities:

  • Single sign-on (SSO) authentication for the Admin Portal.
  • SSO authentication for the Developer Portal.
  • 3scale operator CRD holding OAS3 does not reference as source of truth for 3scale product configuration.

Note

Red Hat 3scale API Management backup and restore is deprecated and no longer the focus of development. Refer to OpenShift APIs for Data Protection information and instructions.

This section provides you, as the administrator of a 3scale installation, the information needed to:

  • Set up the backup procedures for persistent data.
  • Perform a restore from backup of the persistent data.

In case of issues with one or more of the MySQL databases, you will be able to restore 3scale correctly to its previous operational state.

9.1. Prerequisites
Copy link

  • A 3scale 2.15 instance. For more information about how to install 3scale, see Installing 3scale API Management on OpenShift.

  • An OpenShift Container Platform 4.x user account with one of the following roles in the OpenShift cluster:

    • cluster-admin
    • admin
    • edit
Note

A user with an edit cluster role locally binded in the namespace of a 3scale installation can perform backup and restore procedures.

The following contains information about how to set up the backup procedures for persistent data, perform a restore from backup of the persistent data. In case of a failure with one or more of the MySQL databases, I will then be able to restore 3scale correctly to its previous operational state.

9.2. Persistent volumes and considerations
Copy link

Persistent volumes

In a 3scale API Management deployment on OpenShift:

  • A persistent volume (PV) provided to the cluster by the underlying infrastructure.
  • Storage service external to the cluster. This can be in the same data center or elsewhere.

Considerations

The backup and restore procedures for persistent data vary depending on the storage type in use. To ensure the backups and restores preserve data consistency, it is not sufficient to backup the underlying PVs for a database. For example, do not capture only partial writes and partial transactions. Use the database’s backup mechanisms instead.

Some parts of the data are synchronized between different components. One copy is considered the source of truth for the data set. The other is a copy that is not modified locally, but synchronized from the source of truth. In these cases, upon completion, the source of truth should be restored, and copies in other components synchronized from it.

9.3. Using data sets
Copy link

This section explains in more detail about different data sets in the different persistent stores, their purpose, the storage type used, and whether it is the source of truth.

The full state of a 3scale deployment is stored across the following Deployment objects and their PVs:

Expand
NameDescription

system-mysql

MySQL database (mysql-storage)

system-storage

Volume for Files

backend-redis

Redis database (backend-redis-storage)

system-redis

Redis database (system-redis-storage)

9.3.1. Defining system-mysql
Copy link

system-mysql is a relational database which stores information about users, accounts, APIs, plans, and more, in the 3scale Admin Console.

A subset of this information related to services is synchronized to the Backend component and stored in backend-redis. system-mysql is the source of truth for this information.

9.3.2. Defining system-storage
Copy link

system-storage stores files to be read and written by the System component.

They fall into two categories:

  • Configuration files read by the System component at run-time
  • Static files, for example, HTML, CSS, JS, uploaded to system by its CMS feature, for the purpose of creating a Developer Portal
Note

System can be scaled horizontally with multiple pods uploading and reading said static files, hence the need for a ReadWriteMany (RWX) PersistentVolume.

9.3.3. Defining backend-redis
Copy link

backend-redis contains multiple data sets used by the Backend component:

  • Usages: This is API usage information aggregated by Backend. It is used by Backend for rate-limiting decisions and by System to display analytics information in the UI or via API.
  • Config: This is configuration information about services, rate-limits, and more, that is synchronized from System via an internal API. This is not the source of truth of this information, however System and system-mysql is.
  • Queues: This is queues of background jobs to be executed by worker processes. These are ephemeral and are deleted once processed.

9.3.4. Defining system-redis
Copy link

system-redis contains queues for jobs to be processed in background. These are ephemeral and are deleted once processed.

Important

Prevent record creation by scaling down pods like system-app or disabling routes.

In the commands and snippets examples that follow, replace ${DEPLOYMENT_NAME} with the name you defined when you created your 3scale deployment.

Note

Ensure the output includes at least a pair of braces {} and is not empty.

Procedure

9.5.4.1. Operator-based deployments
Copy link
Note

Follow the instructions under Deploying 3scale API Management using the operator, in particular Deploying the APIManager CR to redeploy your 3scale instance.

Procedure

  1. Store the number of replicas, by replacing ${DEPLOYMENT_NAME} with the name you defined when you created your 3scale deployment: 

    ZYNC_SPEC=`oc get APIManager/${DEPLOYMENT_NAME} -o json | jq -r '.spec.zync'`
    Copy to Clipboard Toggle word wrap

  2. Scale down the zync Deployment to 0 pods: 

    $ oc patch APIManager/${DEPLOYMENT_NAME} --type merge -p '{"spec": {"zync": {"appSpec": {"replicas": 0}, "queSpec": {"replicas": 0}}}}'
    Copy to Clipboard Toggle word wrap

  3. Copy the zync database dump to the zync-database pod: 

    $ oc cp ./zync-database-backup.gz $(oc get pods -l 'deployment=zync-database' -o json | jq '.items[0].metadata.name' -r):/var/lib/pgsql/
    Copy to Clipboard Toggle word wrap

  4. Decompress the backup file: 

    $ oc rsh $(oc get pods -l 'deployment=zync-database' -o json | jq -r '.items[0].metadata.name') bash -c 'gzip -d ${HOME}/zync-database-backup.gz'
    Copy to Clipboard Toggle word wrap

  5. Restore zync database backup file: 

    $ oc rsh $(oc get pods -l 'deployment=zync-database' -o json | jq -r '.items[0].metadata.name') bash -c 'psql zync_production -f ${HOME}/zync-database-backup'
    Copy to Clipboard Toggle word wrap

  6. Restore to the original count of replicas: 

    $ oc patch APIManager/${DEPLOYMENT_NAME} --type json -p '[{"op": "replace", "path": "/spec/zync", "value":'"$ZYNC_SPEC"'}]'
    Copy to Clipboard Toggle word wrap

    • If the output of following command does not contain the replicas key: 

      $ echo $ZYNC_SPEC
      Copy to Clipboard Toggle word wrap

    • Then, run the following additional command to scale up zync: 

      $ oc patch deployment/zync -p '{"spec": {"replicas": 1}}'
      Copy to Clipboard Toggle word wrap

By restoring 3scale, you will restore backend-redis and system-redis. These components have the following functions:

*backend-redis: The database that supports application authentication and rate limiting in 3scale. It is also used for statistics storage and temporary job storage. *system-redis: Provides temporary storage for background jobs for 3scale and is also used as a message bus for Ruby processes of system-app pods.

The backend-redis component

The backend-redis component has two databases, data and queues. In default 3scale deployment, data and queues are deployed in the Redis database, but in different logical database indexes /0 and /1. Restoring data database runs without any issues, however restoring queues database can lead to duplicated jobs.

Regarding duplication of jobs, in 3scale the backend workers process background jobs in a matter of milliseconds. If backend-redis fails 30 seconds after the last database snapshot and you try to restore it, the background jobs that happened during those 30 seconds are performed twice because backend does not have a system in place to avoid duplication.

In this scenario, you must restore the backup as the /0 database index contains data that is not saved anywhere else. Restoring /0 database index means that you must also restore the /1 database index since one cannot be stored without the other. When you choose to separate databases on different servers and not one database in different indexes, the size of the queue will be approximately zero, so it is preferable not to restore backups and lose a few background jobs. This will be the case in a 3scale Hosted setup you will need to therefore apply different backup and restore strategies for both.

The `system-redis`component

The majority of the 3scale system background jobs are idempotent, that is, identical requests return an identical result no matter how many times you run them.

The following is a list of examples of events handled by background jobs in system:

  • Notification jobs such as plan trials about to expire, credit cards about to expire, activation reminders, plan changes, invoice state changes, PDF reports.
  • Billing such as invoicing and charging.
  • Deletion of complex objects.
  • Backend synchronization jobs.
  • Indexation jobs, for example with searchd.
  • Sanitisation jobs, for example invoice IDs.
  • Janitorial tasks such as purging audits, user sessions, expired tokens, log entries, suspending inactive accounts.
  • Traffic updates.
  • Proxy configuration change monitoring and proxy deployments.
  • Background signup jobs,
  • Zync jobs such as single sign-on (SSO) synchronization, routes creation.

If you are restoring the above list of background jobs, 3scale’s system maintains the state of each restored job. It is important to check the integrity of the system after the restoration is complete.

After restoring backend-redis a sync of the Config information from system should be forced to ensure the information in backend is consistent with that in system, which is the source of truth.

These steps are intended for running instances of backend-redis.

This document describes how to configure reCAPTCHA for Red Hat 3scale API Management On-premises to protect against spam.

Prerequisites

  • An installed and configured 3scale On-premises instance on a supported OpenShift version.
  • Get a site key and the secret key for reCAPTCHA v2. See the Register a new site web page.
  • Add the Developer Portal domain to an allowlist if you want to use domain name validation.

To configure reCAPTCHA for 3scale, perform the steps outlined in the following procedure:

To configure reCAPTCHA for spam protection, you have two options to patch the secret file that contains the reCAPTCHA. These options are in the OpenShift Container Platform (OCP) user interface or using the command line interface (CLI).

Procedure

  1. OCP 4.x: Navigate to Project: [Your_project_name] > Workloads > Secrets.

  2. Edit the system-recaptcha secret file.

    The PRIVATE_KEY and PUBLIC_KEY from the reCAPTHCA service must be in base64 format encoding. Transform the keys to base64 encoding manually.

Note

The CLI reCAPTCHA option does not require base64 format encoding.

  • CLI: Type the following command: 

    $ oc patch secret/system-recaptcha -p '{"stringData": {"PUBLIC_KEY": "public-key-from-service", "PRIVATE_KEY": "private-key-from-service"}}'
    Copy to Clipboard Toggle word wrap

Post-procedure steps

  • Redeploy the system pod after you have completed one of the above options.

  • In the 3scale Admin Portal, turn on spam protection against users that are not signed:

    1. Navigate to Audience > Developer Portal > Spam Protection.

    2. Select one of the following options:

      • Always

        reCAPTCHA will always appear when a form is presented to a user who is not logged in.

      • Suspicious only

        reCAPTCHA is only shown if the automated checks detect a possible spammer.

      • Never

        Turns off Spam protection.

After system-app has redeployed, the pages that use spam protection on the Developer Portal will show the reCAPTCHA I’m not a robot checkbox.

Important

The threescale-wasm-auth module for integration with OpenShift Service Mesh is deprecated. It is no longer supported starting from Service Mesh 3. While it remains available in earlier versions, anticipate its future decommissioning and avoid relying on it for new deployments. For more details, see the unsupported add-on configurations in Service Mesh 3.

The threescale-wasm-auth module is a WebAssembly module that plugs into Service Mesh and enables it to authorize the incoming requests with Red Hat 3scale API Management. It expands on Service Mesh capabilities and offers full API management capabilities, including authentication, analytics, and billing for your microservices.

Service Mesh focuses on the infrastructure layer with features like traffic management, service discovery, load balancing, and security. API management focuses on creating, publishing, and managing APIs.

Together, Service Mesh and 3scale can improve the reliability, scalability, security, and performance of your microservices and APIs.

Note

The threescale-wasm-auth module runs on integrations of 3scale 2.11 or later with Red Hat OpenShift Service Mesh 2.1.0 or later.

Prerequisites

Cluster administrators on OpenShift Container Platform (OCP) can configure the threescale-wasm-auth module to authorize HTTP requests to 3scale through the WasmPlugin custom resource. The Service Mesh then injects the module into sidecars, exposing the host services and allows you to use the module to process proxy requests.

From a 3scale perspective, the threescale-wasm-auth module serves as a gateway and replaces APIcast when integrating with Service Mesh. This means some of the APIcast features cannot be used, notably policies and staging and production environments.

You can use the example Bookinfo application from Service Mesh to demonstrate the procedure of configuring Service Mesh with 3scale.

Procedure

  1. Deploy Bookinfo application:

  2. Verify that the application is available: 

    $ export GATEWAY_URL=$(oc -n istio-system get route istio-ingressgateway -o jsonpath='{.spec.host}')

$ curl -I "http://$GATEWAY_URL/productpage"
HTTP/1.1 200 OK

11.2. Creating a product in 3scale API Management
Copy link

A product is a customer-facing API that can redirect or use multiple internal APIs, called backends. When using 3scale with Service Mesh, backends are not used. The link between a product and the private base URL is made in the mesh. For this reason, only the product is needed.

Procedure

  1. Create a new product, application plan, and application. See Creating new products to test API calls.

  2. Change deployment to Istio:

    • Navigate to [Your_product_name] > Integration > Settings.
    • Change Deployment to Istio.
    • Click Update Product to update configuration.

  3. Promote the configuration:

    • Navigate to [Your_product_name] > Integration > Configuration.
    • Click Update Configuration.
Important

Create the ServiceEntry custom resource (CR) and DestinationRule CR in the service-mesh/istio-system namespace or the bookinfo namespace. It should be in a namespace containing ServiceMeshControlPlane.

To reach 3scale from Service Mesh you must configure both tenant and backend URLs as an external service through the ServiceEntry CR and the DestinationRule CR. This enables the threescale-wasm-auth module to access both backend, which handles request authorization, and system, from which the product configuration is fetched.

ServiceEntry is needed to allow requests to the service from within the Service Mesh, and DestinationRule is there to configure a secure connection for 3scale services.

11.3.1.1. Adding a tenant URL to Service Mesh
Copy link

Procedure

  1. Collect system tenant URLs:

    • This is a URL of the 3scale Admin Portal you used to create the product.

  2. Create ServiceEntry for system: 

    oc apply -n <bookinfo> -f -<<EOF
apiVersion: networking.istio.io/v1beta1
kind: ServiceEntry
metadata:
  name: <service_entry_threescale_system>
spec:

  ports:
  - number: 443
    name: https
    protocol: HTTPS

11.4. Adding backend URL to Service Mesh
Copy link

By incorporating the 3scale backend URL into your Service Mesh setup, you can establish a secure communication channel between your microservices and the 3scale backend. The integration enables the implementation of authentication, analytics, and billing features for managing APIs in the Service Mesh environment. The backend can be accessed externally using the exposed route and internally using the OpenShift service.

Procedure

  1. Collect backend URLs:

    • For 3scale Hosted, the backend URL is: su1.3scale.net

    • For 3scale On-premises, fetch the URL using the following command: 

      $ oc get -n <3scale_namespace> route backend --template="{{.spec.host}}"
      Copy to Clipboard Toggle word wrap

  2. Create ServiceEntry for backend: 

    oc apply -n <bookinfo> -f -<<EOF
apiVersion: networking.istio.io/v1beta1
kind: ServiceEntry
metadata:
  name: <service_entry_threescale_backend>
spec:
  hosts:
  - <backend_hostname>
  ports:
  - number: 443
    name: https
    protocol: HTTPS
  location: MESH_EXTERNAL
  resolution: DNS
EOF
    Copy to Clipboard Toggle word wrap

  3. Create DestinationRule for backend: 

    oc apply -n <bookinfo> -f -<<EOF
apiVersion: networking.istio.io/v1beta1
kind: DestinationRule
metadata:
  name: <destination_rule_threescale_backend>
spec:
  host: <backend_hostname>
  trafficPolicy:
    tls:
      mode: SIMPLE
      sni: <backend_hostname>
EOF
    Copy to Clipboard Toggle word wrap
Note

The following procedure is an alternative to Adding backend URL to service mesh.

To have the threescale-wasm-auth module authorize requests against 3scale, the module must have access to 3scale services. You can do this within Red Hat OpenShift Service Mesh by applying an external ServiceEntry object and a corresponding DestinationRule object for TLS configuration to use the HTTPS protocol.

The custom resources (CRs) set up the service entries and destination rules for secure access from within Service Mesh to 3scale for the backend and system components of the Service Management API and the Account Management API. The Service Management API receives queries for the authorization status of each request. The Account Management API provides API management configuration settings for your services.

Procedure

  1. Create ServiceEntry for Backend: 

    oc apply -n <bookinfo> -f -<<EOF
apiVersion: networking.istio.io/v1beta1
kind: ServiceEntry
metadata:
  name: <service_entry_threescale_backend>
spec:

11.6. Creating a WasmPlugin custom resource
Copy link

Service Mesh provides a custom resource definition (CRD) to specify and apply Proxy-WASM extensions to sidecar proxies, known as the WasmPlugin. Service Mesh applies the custom resource (CR) to the set of workloads that require HTTP API management with 3scale.

Procedure

  1. Identify the OpenShift Container Platform (OCP) namespace, for example the bookinfo project, on your Service Mesh deployment that you will apply this module to.

  2. Obtain pull secret with registry.redhat.io credentials.

    • Create the new pull secret resource in same namespace as the WasmPlugin.

  3. You must declare the namespace where the threescale-wasm-auth module is deployed, alongside a selector to identify the set of applications the module will apply to. The following example is the YAML format for the CR for threescale-wasm-auth module: 

    apiVersion: extensions.istio.io/v1alpha1
kind: WasmPlugin
metadata:
  name: <threescale_wasm_plugin_name>
 namespace: <namespace>
spec:
  url: oci://registry.redhat.io/3scale-amp2/3scale-auth-wasm-rhel8:0.0.3

        timeout: 5000
      token: <access_token>

    backend:
      name: backend
      upstream:
        name: outbound|<backend_port>||<backend_host>
        url: <backend_url>

              keys:
                - user_key
          - header:
              keys:
                - user_key
    Copy to Clipboard Toggle word wrap
    • The spec.pluginConfig field varies depending on the application. All other fields persist across multiple instances of this custom resource.
    • This particular WasmPlugin spec.pluginConfig is configured with user_key authentication provided in a query string.

    • Explanations:

      • name

        Specifies the unique name or identifier for the WasmPlugin within 3scale.

      • namespace

        Namespace of the workload.

      • imagePullSecret

        The name of the pull secret you created in step 2.

      • selector

        Workload label selector. Use the productpage of the bookinfo project.

      • backend-port

        Depends on which 3scale you are using. See Adding 3scale URLs to Service Mesh. For example, internal 3scale uses port 80 and the external 3scale uses port 443.

      • backend-host and system-host

        Use the same hosts you used in Adding 3scale URLs to Service Mesh.

      • system-url and backend-url

        Use their respective hosts and add a protocol. For example, https://<system-host>.

      • access-token

        Access token to the system tenant.

      • product_id

        The ID of the product you would like to use. If you want multiple products, define multiple products under the services section.

    • After you have the module configuration in spec.pluginConfig and the rest of the custom resource, apply them with the oc apply command: 

      $ oc apply -f threescale-wasm-auth-bookinfo.yaml

OIDC

Apart from the WasmPlugin itself, for OpenID Connect (OIDC) to work, you also need an additional custom resource called RequestAuthentication. When you apply the RequestAuthentication, it configures Envoy with a native plugin to validate JWT tokens. The proxy validates everything before running the module, so any requests that fail do not make it to the 3scale WebAssembly module. 

apiVersion: security.istio.io/v1beta1
kind: RequestAuthentication
metadata:
  name: jwt-example
  namespace: <bookinfo>
spec:

11.7. Testing the configured API
Copy link

You can verify the effectiveness of your API configuration by conducting an authentication check when making calls to your application. By thoroughly testing the authentication mechanism, you can ensure that only authorized requests are processed, maintaining the security and integrity of your application.

Procedure

  1. Try a call to the Bookinfo application with the WasmPlugin applied. It should be rejected as we did not include any authentication: 

    $ export GATEWAY_URL=$(oc -n istio-system get route istio-ingressgateway -o jsonpath='{.spec.host}')

$ curl -I "http://$GATEWAY_URL/productpage"
HTTP/1.1 403
    Copy to Clipboard Toggle word wrap

  2. Retrieve user key for authentication:

    • Navigate to [Your_product_name] > Applications > Listings.
    • Select your application.
    • Look for Authentication > User Key.

  3. Try the call again with user key present. 

    $ curl -I "http://$GATEWAY_URL/productpage?user_key=$USER_KEY"
HTTP/1.1 200 OK
    Copy to Clipboard Toggle word wrap

  4. Verify that the hit was registered in metrics.

    • Navigate to [Your_product_name] > Analytics > Traffic.
    • You should see your calls registered.

The WasmPlugin custom resource spec provides the configuration that the Proxy-WASM module reads from.

The spec is embedded in the host and read by the Proxy-WASM module. Typically, the configurations are in the JSON file format for the modules to parse. However, the WasmPlugin resource can interpret the spec value as YAML and convert it to JSON for consumption by the module.

If you use the Proxy-WASM module in stand-alone mode, you must write the configuration using the JSON format. Using the JSON format means using escaping and quoting where needed within the host configuration files, for example Envoy. When you use the WebAssembly module with the WasmPlugin resource, the configuration is in the YAML format. In this case, an invalid configuration forces the module to show diagnostics based on its JSON representation to a sidecar’s logging stream.

Important

The EnvoyFilter custom resource (CR) is not a supported API, although it can be used in some 3scale Istio adapter or Service Mesh releases. Using the EnvoyFilter CR is not recommended. Use the WasmPlugin API instead of the EnvoyFilter CR. If you must use the EnvoyFilter CR, you must specify the spec in JSON format.

The architecture of the 3scale WebAssembly module configuration depends on the 3scale account and authorization service, and the list of services to handle.

Prerequisites

The prerequisites are a set of minimum mandatory fields in all cases:

  • For the 3scale account and authorization service: the backend-listener URL.
  • For the list of services to handle: the service IDs and at least one credential look up method and where to find it.
  • You will find examples for dealing with userkey, appid with appkey, and OpenID Connect (OIDC) patterns.
  • The WebAssembly module uses the settings you specified in the static configuration. For example, if you add a mapping rule configuration to the module, it will always apply, even when the 3scale Admin Portal has no such mapping rule. The rest of the WasmPlugin resource exists around the spec.pluginConfig YAML entry.

The api top-level string from the 3scale WebAssembly module defines which version of the configuration the module will use.

Note

A non-existent or unsupported version of the api object renders the 3scale WebAssembly module inoperable.

The api top-level string example

apiVersion: extensions.istio.io/v1alpha1
kind: WasmPlugin
metadata:
  name: <threescale_wasm_plugin_name>
  namespace: <bookinfo>
spec:
  pluginConfig:
    api: v1
...
Copy to Clipboard Toggle word wrap

The api entry defines the rest of the values for the configuration. The only accepted value is v1. New settings that break compatibility with the current configuration or need more logic that modules using v1 cannot handle will require different values.

The system top-level object specifies how to access the 3scale Account Management API for a specific account. The upstream field is the most important part of the object. The system object is optional, but recommended unless you are providing a fully static configuration for the 3scale WebAssembly module. The latter is an option if you do not want to provide connectivity to the system component of 3scale.

When you provide static configuration objects in addition to the system object, the static ones always take precedence.

authorities

An array of strings, each one representing the Authority of a URL to match. These strings accept glob patterns supporting the asterisk (*), plus sign (+), and question mark (?) matchers.

Yes

credentials

An object defining which kind of credentials to look for and where.

Yes

mapping_rules

An array of objects representing mapping rules and 3scale methods to hit.

Optional

The credentials object is a component of the service object. credentials specifies which kind of credentials to be looked up and the steps to perform this action.

All fields are optional, but you must specify at least one, user_key or app_id. The order in which you specify each credential is irrelevant because it is pre-established by the module. Only specify one instance of each credential.

user_key

This is an array of lookup queries that defines a 3scale user key. A user key is commonly known as an API key.

Optional

app_id

This is an array of lookup queries that define a 3scale application identifier. Application identifiers are provided by 3scale or by using an identity provider like Red Hat single sign-on, Red Hat build of Keycloak or OpenID Connect (OIDC). The resolution of the lookup queries specified here, whenever it is successful and resolves to two values, it sets up the app_id and the app_key.

Optional

app_key

This is an array of lookup queries that define a 3scale application key. Application keys without a resolved app_id are useless, so only specify this field when app_id has been specified.

Optional

The lookup query object is part of any of the fields in the credentials object. It specifies how a given credential field should be found and processed. When evaluated, a successful resolution means that one or more values were found. A failed resolution means that no values were found.

Arrays of lookup queries describe a short-circuit or relationship: a successful resolution of one of the queries stops the evaluation of any remaining queries and assigns the value or values to the specified credential-type. Each query in the array is independent of each other.

A lookup query is made up of a single field, a source object, which can be one of a number of source types. See the following example: 

apiVersion: extensions.istio.io/v1alpha1
kind: WasmPlugin
metadata:
  name: <threescale_wasm_plugin_name>
spec:
  pluginConfig:
    ...
    services:
    - credentials:
        user_key:
          - <source_type>: <object>
          - <source_type>: <object>
          ...
        app_id:
          - <source_type>: <object>
          ...
        app_key:
          - <source_type>: <object>
          ...
    ...
Copy to Clipboard Toggle word wrap

A source object exists as part of an array of sources within any of the credentials object fields. The object field name, referred to as a source-type is any one of the following:

  • header: The lookup query receives HTTP request headers as input.
  • query_string: The lookup query receives the URL query string parameters as input.
  • filter: The lookup query receives filter metadata as input.

All source-type objects have at least the following two fields:

Expand
Table 11.6. source-type object fields
NameDescriptionRequired

keys

An array of strings, each one a key, referring to entries found in the input data.

Yes

ops

An array of operations that perform a key entry match. The array is a pipeline where operations receive inputs and generate outputs on the next operation. An operation failing to provide an output resolves the lookup query as failed. The pipeline order of the operations determines the evaluation order.

Optional

path

Shows the path in the metadata used to look up data. However, it is not required when header or query_string source type is used, but it is required when the filter source-type is used.

Optional

When a key matches the input data, the rest of the keys are not evaluated and the source resolution algorithm jumps to executing the operations (ops) specified, if any. If no ops are specified, the result value of the matching key, if any, is returned.

Operations provide a way to specify certain conditions and transformations for inputs you have after the first phase looks up a key. Use operations when you need to transform, decode, and assert properties, however they do not provide a mature language to deal with all needs and lack Turing-completeness.

A stack stored the outputs of operations. When evaluated, the lookup query finishes by assigning the value or values at the bottom of the stack, depending on how many values the credential consumes.

Each element in the ops array belonging to a specific source type is an operation object that either applies transformations to values or performs tests. The field name to use for such an object is the name of the operation itself, and any values are the parameters to the operation, which could be structure objects, for example, maps with fields and values, lists, or strings.

Most operations attend to one or more inputs, and produce one or more outputs. When they consume inputs or produce outputs, they work with a stack of values: each value consumed by the operations is popped from the stack of values and initially populated with any source matches. The values outputted by them are pushed to the stack. Other operations do not consume or produce outputs other than asserting certain properties, but they inspect a stack of values.

Note

When resolution finishes, the values picked up by the next step, such as assigning the values to be an app_id, app_key, or user_key, are taken from the bottom values of the stack.

There are a few different operations categories:

  • decode

    These transform an input value by decoding it to get a different format.

  • string

    These take a string value as input and perform transformations and checks on it.

  • stack

    These take a set of values in the input and perform multiple stack transformations and selection of specific positions in the stack.

  • check

    These assert properties about sets of operations in a side-effect free way.

  • control

    These perform operations that allow for modifying the evaluation flow.

  • format

    These parse the format-specific structure of input values and look up values in it.

All operations are specified by the name identifiers as strings.

The mapping_rules object is part of the service object. It specifies a set of REST path patterns and related 3scale metrics and count increments to use when the patterns match.

You need the value if no dynamic configuration is provided in the system top-level object. If the object is provided in addition to the system top-level entry, then the mapping_rules object is evaluated first.

mapping_rules is an array object. Each element of that array is a mapping_rule object. The evaluated matching mapping rules on an incoming request provide the set of 3scale methods for authorization and reporting to the APIManager. When multiple matching rules refer to the same methods, there is a summation of deltas when calling into 3scale. For example, if two rules increase the Hits method twice with deltas of 1 and 3, a single method entry for Hits reporting to 3scale has a delta of 4.

The mapping_rule object is part of an array in the mapping_rules object.

The mapping_rule object fields specify the following information:

  • The HTTP request method to match.
  • A pattern to match the path against.
  • The 3scale methods to report along with the amount to report. The order in which you specify the fields determines the evaluation order.
Expand
Table 11.7. mapping_rule object fields
NameDescriptionRequired

method

Specifies a string representing an HTTP request method, also known as verb. Values accepted match the any one of the accepted HTTP method names, case-insensitive. A special value of any matches any method.

Yes

pattern

The pattern to match the HTTP request’s URI path component. This pattern follows the same syntax as documented by 3scale. It allows wildcards, use of the asterisk (*) character, using any sequence of characters between braces such as {this}.

Yes

usages

A list of usage objects. When the rule matches, all methods with their deltas are added to the list of methods sent to 3scale for authorization and reporting.

Embed the usages object with the following required fields:

  • name: The method system name to report. Note: name is case sensitive.
  • delta: For how much to increase that method by.

Yes

last

Whether the successful matching of this rule should stop the evaluation of more mapping rules.

Optional Boolean. The default is false

The following example is independent of existing hierarchies between methods in 3scale. That is, anything run on the 3scale side will not affect this. For example, the Hits metric might be a parent of them all, so it stores 4 hits due to the sum of all reported methods in the authorized request and calls the 3scale Authrep API endpoint.

The example below uses a GET request to a path, /products/1/sold, that matches all the rules.

All usages get added to the request the module performs to 3scale with usage data as follows:

  • Hits: 1
  • products: 2
  • sales: 1

You will spend most of your time applying configuration steps to obtain credentials in the requests to your services.

The following are credentials examples, which you can modify to adapt to specific use cases.

You can combine them all, although when you specify multiple source objects with their own lookup queries, they are evaluated in order until one of them successfully resolves.

The following example looks up a user_key in a query string parameter or header of the same name: 

credentials:
  user_key:
    - query_string:
        keys:
          - user_key

    - query_string:
        keys:
          - app_key
Copy to Clipboard Toggle word wrap

11.9.3. Authorization header
Copy link

A request includes an app_id and app_key in an authorization header. If there is at least one or two values outputted at the end, then you can assign the app_key.

The resolution here assigns the app_key if there is one or two outputted at the end.

The authorization header specifies a value with the type of authorization and its value is encoded as Base64. This means you can split the value by a space character, take the second output and then split it again using a colon (:) as the separator. For example, if you use this format app_id:app_key, the header looks like the following example for credential: 

aladdin:opensesame: Authorization: Basic YWxhZGRpbjpvcGVuc2VzYW1l
Copy to Clipboard Toggle word wrap

You must use lowercase header field names as shown in the following example: 

credentials:
  app_id:
    - header:
        keys:
          - authorization
        ops:
          - split:
              separator: " "
              max: 2
          - length:
              min: 2
          - drop:
              head: 1
          - base64_urlsafe
          - split:
              max: 2
  app_key:
    - header:
        keys:
          - app_key
Copy to Clipboard Toggle word wrap

The previous example use case looks at the headers for an authorization:

  1. It takes its string value and split it by a space, checking that it generates at least two values of a credential-type and the credential itself, then dropping the credential-type.

  2. It then decodes the second value containing the data it needs, and splits it by using a colon (:) character to have an operations stack including first the app_id, then the app_key, if it exists.

    1. If app_key does not exist in the authorization header then its specific sources are checked. For example, the header with the key app_key in this case.
  3. To add extra conditions to credentials, allow Basic authorizations, where app_id is either aladdin or admin, or any app_id being at least 8 characters in length.

  4. app_key must contain a value and have a minimum of 64 characters as shown in the following example: 

    credentials:
  app_id:
    - header:
        keys:
          - authorization
        ops:
          - split:
              separator: " "
              max: 2
          - length:
              min: 2
          - reverse
          - glob:
            - Basic
          - drop:
              tail: 1
          - base64_urlsafe
          - split:
              max: 2
          - test:
              if:
                length:
                  min: 2
              then:
                - strlen:
                    max: 63
                - or:
                    - strlen:
                        min: 1
                    - drop:
                        tail: 1
          - assert:
            - and:
              - reverse
              - or:
                - strlen:
                    min: 8
                - glob:
                  - aladdin
                  - admin
    Copy to Clipboard Toggle word wrap
  5. After picking up the authorization header value, you get a Basic credential-type by reversing the stack so that the type is placed on top.
  6. Run a glob match on it. When it validates, and the credential is decoded and split, you get the app_id at the bottom of the stack, and potentially the app_key at the top.

  7. Run a test: if there are two values in the stack, meaning an app_key was acquired.

    1. Ensure the string length is between 1 and 63, including app_id and app_key. If the key’s length is zero, drop it and continue as if no key exists. If there was only an app_id and no app_key, the missing else branch indicates a successful test and evaluation continues.

The last operation, assert, indicates that no side-effects make it into the stack. You can then modify the stack:

  1. Reverse the stack to have the app_id at the top.

    1. Whether or not an app_key is present, reversing the stack ensures app_id is at the top.

  2. Use and to preserve the contents of the stack across tests.

    Then use one of the following possibilities:

    • Make sure app_id has a string length of at least 8.
    • Make sure app_id matches either aladdin or admin.

11.9.4. OpenID Connect (OIDC) use case
Copy link

For Service Mesh and the 3scale Istio adapter, you must deploy a RequestAuthentication as shown in the following example, filling in your own workload data and jwtRules: 

apiVersion: security.istio.io/v1beta1
kind: RequestAuthentication
metadata:
  name: jwt-example
  namespace: <bookinfo>
spec:
  selector:
    matchLabels:
      app: <productpage>
  jwtRules:
  - issuer: >-
      "<url>/auth/realms/<realm_name>"
    jwksUri: >-
      "<url>/auth/realms/<realm_name>/protocol/openid-connect/certs"
Copy to Clipboard Toggle word wrap

When you apply the RequestAuthentication, it configures Envoy with a native plugin to validate JWT tokens. The proxy validates everything before running the module, so any requests that fail do not make it to the 3scale WebAssembly module.

When a JWT token is validated, the proxy stores its contents in an internal metadata object, with an entry whose key depends on the specific configuration of the plugin. This use case gives you the ability to look up structure objects with a single entry containing an unknown key name.

The 3scale app_id for OIDC matches the OAuth client_id. This is found in the azp or aud fields of JWT tokens.

To get app_id field from Envoy’s native JWT authentication filter, see the following example: 

credentials:
  app_id:
    - filter:
        path:
          - envoy.filters.http.jwt_authn
          - "0"
        keys:
          - azp
          - aud
        ops:
          - take:
              head: 1
Copy to Clipboard Toggle word wrap

The example instructs the module to use the filter source type to look up filter metadata for an object from the Envoy-specific JWT authentication native plugin. This plugin includes the JWT token as part of a structure object with a single entry and a pre-configured name. Use 0 to specify that you will only access the single entry.

The resulting value is a structure for which you will resolve two fields:

  • azp: The value where app_id is found.
  • aud: The value where this information can also be found.

The operation ensures only one value is held for assignment.

11.9.5. Picking up the JWT token from a header
Copy link

Some setups might have validation processes for JWT tokens, where the validated token would reach this module via a header in JSON format.

To get the app_id, see the following example: 

credentials:
  app_id:
    - header:
        keys:
          - x-jwt-payload
        ops:
          - base64_urlsafe
          - json:
            - keys:
              - azp
              - aud
          - take:

Additional resources

This guide aims to help you identify and fix the cause of issues with your API infrastructure.

API Infrastructure is a lengthy and complex topic. However, at a minimum, you will have three moving parts in your Infrastructure:

  1. The API gateway
  2. 3scale
  3. The API
3scale Gateway Flowchart
View larger image
3scale Gateway Flowchart

Errors in any of these three elements result in API consumers being unable to access your API. However, it is difficult to find the component that caused the failure. This guide gives you some tips to troubleshoot your infrastructure to identify the problem.

Use the following sections to identify and fix common issues that may occur:

12.1. Common integration issues
Copy link

There are some evidences that can point to some very common issues with your integration with 3scale. These will vary depending on whether you are at the beginning of your API project, setting up your infrastructure, or are already live in production.

12.1.1. Integration issues
Copy link

The following sections attempt to outline some common issues you may see in the APIcast error log during the initial phases of your integration with 3scale: at the beginning using APIcast Hosted and prior to go-live, running the self-managed APIcast.

12.1.1.1. APIcast Hosted
Copy link

When you are first integrating your API with APIcast Hosted on the Service Integration screen, you might get some of the following errors shown on the page or returned by the test call you make to check for a successful integration.

  • Test request failed: execution expired

    Check that your API is reachable from the public internet. APIcast Hosted cannot be used with private APIs. If you do not want to make your API publicly available to integrate with APIcast Hosted, you can set up a private secret between APIcast Hosted and your API to reject any calls not coming from the API gateway.

  • The accepted format is protocol://address(:port)

    Remove any paths at the end of your APIs private base URL. You can add these in the "mapping rules" pattern or at the beginning of the API test GET request.

  • Test request failed with HTTP code XXX

    • 405: Check that the endpoint accepts GET requests. APIcast only supports GET requests to test the integration.
    • 403: Authentication parameters missing: If your API already has some authentication in place, APIcast will be unable to make a test request.
    • 403: Authentication failed: If this is not the first service you have created with 3scale, check that you have created an application under the service with credentials to make the test request. If it is the first service you are integrating, ensure that you have not deleted the test account or application that you created on signup.
12.1.1.2. APIcast self-managed
Copy link

After you have successfully tested the integration with APIcast self-managed, you might want to host the API gateway yourself. Following are some errors you may encounter when you first install your self-managed gateway and call your API through it.

  • upstream timed out (110: Connection timed out) while connecting to upstream

    Check that there are no firewalls or proxies between the API Gateway and the public Internet that would prevent your self-managed gateway from reaching 3scale.

  • failed to get list of services: invalid status: 403 (Forbidden)

    Check that the Access Token that you used in the THREESCALE_PORTAL_ENDOINT value is correct and that it has the Account Management API scope. Verify it with a curl command: curl -v "https://example-admin.3scale.net/admin/api/services.json?access_token=<YOUR_ACCESS_TOKEN>"

    It should return a 200 response with a JSON body. If it returns an error status code, check the response body for details.

    This error indicates that the Public Base URL has not been configured properly. You should ensure that the configured Public Base URL is the same that you use for the request to self-managed APIcast. After configuring the correct Public Base URL:

    • Ensure that APIcast is configured for "production" (default configuration for standalone APIcast if not overriden with THREESCALE_DEPLOYMENT_ENV variable). Ensure that you promote the configuration to production.
    • Restart APIcast, if you have not configured auto-reloading of configuration using APICAST_CONFIGURATION_CACHE and APICAST_CONFIGURATION_LOADER environment variables.

Following are some other symptoms that may point to an incorrect APIcast self-managed integration:

  • Mapping rules not matched / Double counting of API calls: Depending on the way you have defined the mapping between methods and actual URL endpoints on your API, you might find that sometimes methods either don’t get matched or get incremented more than once per request. To troubleshoot this, make a test call to your API with the 3scale debug header. This will return a list of all the methods that have been matched by the API call.
  • Authentication parameters not found: Ensure your are sending the parameters to the correct location as specified in the Service Integration screen. If you do not send credentials as headers, the credentials must be sent as query parameters for GET requests and body parameters for all other HTTP methods. Use the 3scale debug header to double-check the credentials that are being read from the request by the API gateway.

12.1.2. Production issues
Copy link

It is rare to run into issues with your API gateway after you have fully tested your setup and have been live with your API for a while. However, here are some of the issues you might encounter in a live production environment.

12.1.2.1. Availability issues
Copy link

Availability issues are normally characterised by upstream timed out errors in your nginx error.log; example: 

upstream timed out (110: Connection timed out) while connecting to upstream, client: X.X.X.X, server: api.example.com, request: "GET /RESOURCE?CREDENTIALS HTTP/1.1", upstream: "http://Y.Y.Y.Y:80/RESOURCE?CREDENTIALS", host: "api.example.com"

If you are experiencing intermittent 3scale availability issues, following may be the reasons for this:

  • You are resolving to an old 3scale IP that is no longer in use.

    The latest version of the API gateway configuration files defines 3scale as a variable to force IP resolution each time. For a quick fix, reload your NGINX instance. For a long-term fix, ensure that instead of defining the 3scale backend in an upstream block, you define it as a variable within each server block; example: 

    server {
  # Enabling the Lua code cache is strongly encouraged for production use. Here it is enabled
  .
  .
  .
  set $threescale_backend "https://su1.3scale.net:443";
    Copy to Clipboard Toggle word wrap

    When you refer to it: 

    location = /threescale_authrep {
  internal;
  set $provider_key "YOUR_PROVIDER_KEY";

  proxy_pass $threescale_backend/transactions/authrep.xml?provider_key=$provider_key&service_id=$service_id&$usage&$credentials&log%5Bcode%5D=$arg_code&log%5Brequest%5D=$arg_req&log%5Bresponse%5D=$arg_resp;
}
    Copy to Clipboard Toggle word wrap

  • You are missing some 3scale IPs from your whitelist. Following is the current list of IPs that 3scale resolves to:

    • 75.101.142.93
    • 174.129.235.69
    • 184.73.197.122
    • 50.16.225.117
    • 54.83.62.94
    • 54.83.62.186
    • 54.83.63.187

    • 54.235.143.255

      The above issues refer to problems with perceived 3scale availability. However, you might encounter similar issues with your API availability from the API gateway if your API is behind an AWS ELB. This is because NGINX, by default, does DNS resolution at start-up time and then caches the IP addresses. However, ELBs do not ensure static IP addresses and these might change frequently. Whenever the ELB changes to a different IP, NGINX is unable to reach it.

      The solution for this is similar to the above fix for forcing runtime DNS resolution.

      1. Set a specific DNS resolver such as Google DNS, by adding this line at the top of the http section: resolver 8.8.8.8 8.8.4.4;.
      2. Set your API base URL as a variable anywhere near the top of the server section. set $api_base "http://api.example.com:80";
      3. Inside the location / section, find the proxy_pass line and replace it with proxy_pass $api_base;.

12.1.3. Post-deploy issues
Copy link

If you make changes to your API such as adding a new endpoint, you must ensure that you add a new method and URL mapping before downloading a new set of configuration files for your API gateway.

The most common problem when you have modified the configuration downloaded from 3scale will be code errors in the Lua, which will result in a 500 - Internal server error such as: 

curl -v -X GET "http://localhost/"

You can see the nginx error.log to know the cause, such as:

The above section gives you a an overview of the most common, well-known issues that you might encounter at any stage of your 3scale journey.

If all of these have been checked and you are still unable to find the cause and solution for your issue, you should proceed to the more detailed section on Identifying API request issues. Start at your API and work your way back to the client in order to try to identify the point of failure.

12.2. Handling API infrastructure issues
Copy link

If you are experiencing failures when connecting to a server, whether that is the API gateway, 3scale, or your API, the following troubleshooting steps should be your first port of call:

12.2.1. Can we connect?
Copy link

Use telnet to check the basic TCP/IP connectivity telnet api.example.com 443

  • Success 
telnet echo-api.3scale.net 80
Trying 52.21.167.109...
Connected to tf-lb-i2t5pgt2cfdnbdfh2c6qqoartm-829217110.us-east-1.elb.amazonaws.com.

  • Failure 
telnet su1.3scale.net 443
Trying 174.129.235.69...
telnet: Unable to connect to remote host: Connection timed out
Copy to Clipboard Toggle word wrap

12.2.2. Server connection issues
Copy link

Try to connect to the same server from different network locations, devices, and directions. For example, if your client is unable to reach your API, try to connect to your API from a machine that should have access such as the API gateway.

If any of the attempted connections succeed, you can rule out any problems with the actual server and concentrate your troubleshooting on the network between them, as this is where the problem will most likely be.

12.2.3. Is it a DNS issue?
Copy link

Try to connect to the server by using its IP address instead of its hostname e.g. telnet 94.125.104.17 80 instead of telnet apis.io 80

This will rule out any problems with the DNS.

You can get the IP address for a server using dig for example for 3scale dig su1.3scale.net or dig any su1.3scale.net if you suspect there may be multiple IPs that a host may resolve to.

NB: Some hosts block `dig any`

12.2.4. Is it an SSL issue?
Copy link

You can use OpenSSL to test:

  • Secure connections to a host or IP, such as from the shell prompt openssl s_client -connect su1.3scale.net:443

    Output:

12.3. Identifying API request issues
Copy link

To identify where an issue with requests to your API might lie, go through the following checks.

12.3.1. API
Copy link

To confirm that the API is up and responding to requests, make the same request directly to your API (not going through the API gateway). You should ensure that you are sending the same parameters and headers as the request that goes through the API gateway. If you are unsure of the exact request that is failing, capture the traffic between the API gateway and your API.

If the call succeeds, you can rule out any problems with the API, otherwise you should troubleshoot your API further.

12.3.2. API Gateway > API
Copy link

To rule out any network issues between the API gateway and the API, make the same call as before — directly to your API — from your API gateway server.

If the call succeeds, you can move on to troubleshooting the API gateway itself.

12.3.3. API gateway
Copy link

There are a number of steps to go through to check that the API gateway is working correctly.

12.3.3.1. Is the API gateway up and running?
Copy link

Log in to the machine where the gateway is running. If this fails, your gateway server might be down.

After you have logged in, check that the NGINX process is running. For this, run ps ax | grep nginx or htop.

NGINX is running if you see nginx master process and nginx worker process in the list.

Following are some common errors you might see in the gateway logs, for example in error.log:

  • API gateway can’t connect to API 

    upstream timed out (110: Connection timed out) while connecting to upstream, client: X.X.X.X, server: api.example.com, request: "GET /RESOURCE?CREDENTIALS HTTP/1.1", upstream: "http://Y.Y.Y.Y:80/RESOURCE?CREDENTIALS", host: "api.example.com"
    Copy to Clipboard Toggle word wrap

  • API gateway cannot connect to 3scale 

    2015/11/20 11:33:51 [error] 3578#0: *1 upstream timed out (110: Connection timed out) while connecting to upstream, client: 127.0.0.1, server: , request: "GET /api/activities.json?user_key=USER_KEY HTTP/1.1", subrequest: "/threescale_authrep", upstream: "https://54.83.62.186:443/transactions/authrep.xml?provider_key=YOUR_PROVIDER_KEY&service_id=SERVICE_ID&usage[hits]=1&user_key=USER_KEY&log%5Bcode%5D=", host: "localhost"
    Copy to Clipboard Toggle word wrap

12.3.4. API gateway > 3scale API Management
Copy link

Once you are sure the API gateway is running correctly, the next step is troubleshooting the connection between the API gateway and 3scale.

If you are using NGINX as your API gateway, the following message displays in the nginx error logs when the gateway is unable to contact 3scale. 

2015/11/20 11:33:51 [error] 3578#0: *1 upstream timed out (110: Connection timed out) while connecting to upstream, client: 127.0.0.1, server: , request: "GET /api/activities.json?user_key=USER_KEY HTTP/1.1", subrequest: "/threescale_authrep", upstream: "https://54.83.62.186:443/transactions/authrep.xml?provider_key=YOUR_PROVIDER_KEY&service_id=SERVICE_ID&usage[hits]=1&user_key=USER_KEY&log%5Bcode%5D=", host: "localhost"
Copy to Clipboard Toggle word wrap

Here, note the upstream value. This IP corresponds to one of the IPs that the 3scale product resolves to. This implies that there is a problem reaching 3scale. You can do a reverse DNS lookup to check the domain for an IP by calling nslookup.

For example, because the API gateway is unable to reach 3scale, it does not mean that 3scale is down. One of the most common reasons for this would be firewall rules preventing the API gateway from connecting to 3scale.

There may be network issues between the gateway and 3scale that could cause connections to timeout. In this case, you should go through the steps in troubleshooting generic connectivity issues to identify where the problem lies.

To rule out networking issues, use traceroute or MTR to check the routing and packet transmission. You can also run the same command from a machine that is able to connect to 3scale and your API gateway and compare the output.

Additionally, to see the traffic that is being sent between your API gateway and 3scale, you can use tcpdump as long as you temporarily switch to using the HTTP endpoint for the 3scale product (su1.3scale.net).

Ensure you have the resolver directive added to your nginx.conf.

For example, in nginx.conf: 

http {
  lua_shared_dict api_keys 10m;
  server_names_hash_bucket_size 128;
  lua_package_path ";;$prefix/?.lua;";
  init_by_lua 'math.randomseed(ngx.time()) ; cjson = require("cjson")';

  resolver 8.8.8.8 8.8.4.4;
Copy to Clipboard Toggle word wrap

You can substitute the Google DNS (8.8.8.8 and 8.8.4.4) with your preferred DNS.

To check DNS resolution from your API gateway, call nslookup as follows with the specified resolver IP: 

nslookup su1.3scale.net 8.8.8.8
;; connection timed out; no servers could be reached
Copy to Clipboard Toggle word wrap

The above example shows the response returned if Google DNS cannot be reached. If this is the case, you must update the resolver IPs. You might also see the following alert in your nginx error.log: 

2016/05/09 14:15:15 [alert] 9391#0: send() failed (1: Operation not permitted) while resolving, resolver: 8.8.8.8:53
Copy to Clipboard Toggle word wrap

Finally, run dig any su1.3scale.net to see the IP addresses currently in operation for the 3scale Service Management API. Note that this is not the entire range of IP addresses that might be used by 3scale. Some may be swapped in and out for capacity reasons. Additionally, you may add more domain names for the 3scale service in the future. For this you should always test against the specific address that are supplied to you during integration, if applicable.

If you want to check the request your API gateway is making to 3scale for troubleshooting purposes only you can add the following snippet to the 3scale authrep location in nginx.conf (/threescale_authrep for API Key and App\_id authentication modes): 

body_filter_by_lua_block{
  if ngx.req.get_headers()["X-3scale-debug"] == ngx.var.provider_key then
    local resp = ""
    ngx.ctx.buffered = (ngx.ctx.buffered or "") .. string.sub(ngx.arg[1], 1, 1000)
    if ngx.arg[2] then
      resp = ngx.ctx.buffered
    end

    ngx.log(0, ngx.req.raw_header())
    ngx.log(0, resp)
  end
}
Copy to Clipboard Toggle word wrap

This snippet will add the following extra logging to the nginx error.log when the X-3scale-debug header is sent, e.g. curl -v -H 'X-3scale-debug: YOUR_PROVIDER_KEY' -X GET "https://726e3b99.ngrok.com/api/contacts.json?access_token=7c6f24f5"

This will produce the following log entries: 

2016/05/05 14:24:33 [] 7238#0: *57 [lua] body_filter_by_lua:7: GET /api/contacts.json?access_token=7c6f24f5 HTTP/1.1

Copy to Clipboard Toggle word wrap

The first entry (2016/05/05 14:24:33 [] 7238#0: *57 [lua] body_filter_by_lua:7:) prints out the request headers sent to 3scale, in this case: Host, User-Agent, Accept, X-Forwarded-Proto and X-Forwarded-For.

The second entry (2016/05/05 14:24:33 [] 7238#0: *57 [lua] body_filter_by_lua:8:) prints out the response from 3scale, in this case: <error code="access_token_invalid">access_token "7c6f24f5" is invalid: expired or never defined</error>.

Both will print out the original request (GET /api/contacts.json?access_token=7c6f24f5) and subrequest location (/threescale_authrep) as well as the upstream request (upstream: "https://54.83.62.94:443/transactions/threescale_authrep.xml?provider_key=REDACTED&service_id=REDACTED&usage[hits]=1&access_token=7c6f24f5".) This last value allows you to see which of the 3scale IPs have been resolved and also the exact request made to 3scale.

12.3.5. 3scale API Management
Copy link

It is also possible that 3scale is available but is returning an error to your API gateway which would prevent calls going through to your API. Try to make the authorization call directly in 3scale and check the response. If you get an error, check the #troubleshooting-api-error-codes[Error Codes] section to see what the issue is.

You can also turn on the 3scale debug headers by making a call to your API with the X-3scale-debug header, example:

curl -v -X GET "https://api.example.com/endpoint?user_key" X-3scale-debug: YOUR_SERVICE_TOKEN

This will return the following headers with the API response: 

X-3scale-matched-rules: /, /api/contacts.json
< X-3scale-credentials: access_token=TOKEN_VALUE
< X-3scale-usage: usage[hits]=2
< X-3scale-hostname: HOSTNAME_VALUE
Copy to Clipboard Toggle word wrap
12.3.5.3. Check the integration errors
Copy link

You can also check the integration errors on your Admin Portal to check for any issues reporting traffic to 3scale. See https://YOUR_DOMAIN-admin.3scale.net/apiconfig/errors.

One of the reasons for integration errors can be sending credentials in the headers with underscores_in_headers directive not enabled in server block.

12.3.6. Client API gateway
Copy link

Try directing a browser to the IP address (or domain name) of your gateway server. If this fails, ensure that you have opened the firewall on the relevant ports.

If possible, try to connect to the API gateway from the client using one of the methods outlined earlier (telnet, curl, etc.) If the connection fails, the problem lies in the network between the two.

Otherwise, you should move on to troubleshooting the client making the calls to the API.

12.3.7. Client
Copy link

If a request is not returning the expected result, test with a different HTTP client. For example, if you are calling an API with a Java HTTP client and you see something wrong, cross-check with cURL.

You can also call the API through a proxy between the client and the gateway to capture the exact parameters and headers being sent by the client.

12.3.7.2. Inspect the traffic sent by client
Copy link

Use a tool like Wireshark to see the requests being made by the client. This will allow you to identify if the client is making calls to the API and the details of the request.

12.4. ActiveDocs issues
Copy link

Sometimes calls that work when you call the API from the command line fail when going through ActiveDocs.

To enable ActiveDocs calls to work, we send these out through a proxy on our side. This proxy will add certain headers that can sometimes cause issues on the API if they are not expected. To identify if this is the case, try the following steps:

12.4.1. Use petstore.swagger.io
Copy link

Swagger provides a hosted swagger-ui at petstore.swagger.io which you can use to test your Swagger spec and API going through the latest version of swagger-ui. If both swagger-ui and ActiveDocs fail in the same way, you can rule out any issues with ActiveDocs or the ActiveDocs proxy and focus the troubleshooting on your own spec. Alternatively, you can check the swagger-ui GitHub repo for any known issues with the current version of swagger-ui.

We recommend to not whitelist IP address for clients using your API. The ActiveDocs proxy uses floating IP addresses for high availability and there is currently no mechanism to notify of any changes to these IPs.

12.4.3. Call the API with incorrect credentials
Copy link

One way to identify whether the ActiveDocs proxy is working correctly is to call your API with invalid credentials. This will help you to confirm or rule out any problems with both the ActiveDocs proxy and your API gateway.

If you get a 403 code back from the API call (or from the code you have configured on your gateway for invalid credentials), the problem lies with your API because the calls are reaching your gateway.

12.4.4. Compare calls
Copy link

To identify any differences in headers and parameters between calls made from ActiveDocs versus outside of ActiveDocs, run calls through services such as APItools on-premise or Runscope. This will allow you to inspect and compare your HTTP calls before sending them to your API. You will then be able to identify potential headers and/or parameters in the request that could cause issues.

12.5. Logging in NGINX
Copy link

For a comprehensive guide on this, see the NGINX Logging and Monitoring docs.

12.5.1. Enabling debugging log
Copy link

To find out more about enabling debugging log, see the NGINX debugging log documentation.

12.6. 3scale error codes
Copy link

To double-check the error codes that are returned by the 3scale Service Management API endpoints, see the 3scale API Documentation page by following these steps:

  1. Click the question mark (?) icon, which is in the upper-right corner of the Admin Portal.
  2. Choose 3scale API Docs.

The following is a list HTTP response codes returned by 3scale, and the conditions under which they are returned:

  • 400: Bad request. This can be because of:

    • Invalid encoding
    • Payload too large
    • Content type is invalid (for POST calls). Valid values for the Content-Type header are: application/x-www-form-urlencoded, multipart/form-data, or empty header.

  • 403:

    • Credentials are not valid
    • Sending body data to 3scale for a GET request
  • 404: Non-existent entity referenced, such as applications, metrics, etc.

  • 409:

    • Usage limits exceeded
    • Application is not active
    • Application key is invalid or missing (for app_id/app_key authentication method)
    • Referrer is not allowed or missing (when referrer filters are enabled and required)
  • 422: Missing required parameters

Most of these error responses will also contain an XML body with a machine readable error category and a human readable explanation.

When using the standard API gateway configuration, any return code different from 200 provided by 3scale can result in a response to the client with one of the following codes:

  • 403
  • 404
