Chapter 2. Installing 3scale on OpenShift

1. Create an Identity and Access Management (IAM) policy with the following minimum permissions:

   {
       "Version": "2012-10-17",
       "Statement": [
           {
               "Effect": "Allow",
               "Action": "s3:ListAllMyBuckets",
               "Resource": "arn:aws:s3:::*"
           },
           {
               "Effect": "Allow",
               "Action": "s3:*",
               "Resource": [
                   "arn:aws:s3:::targetBucketName",
                   "arn:aws:s3:::targetBucketName/*"
               ]
           }
       ]
   }

2. Create a CORS configuration with the following rules:

   <?xml version="1.0" encoding="UTF-8"?>
   <CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
   <CORSRule>
       <AllowedOrigin>https://*</AllowedOrigin>
       <AllowedMethod>GET</AllowedMethod>
   </CORSRule>
   </CORSConfiguration>

Procedure

1. Navigate to the Registry Service Accounts page and log in.

2. Click New Service Account. Fill in the form on the Create a New Registry Service Account page.

   1. Add a name for the service account.

      Note: You will see a fixed-length, randomly generated number string before the form field.

3. Enter a Description.
4. Click Create.
5. Navigate back to your Service Accounts.
6. Click the Service Account you created.

7. Make a note of the username, including the prefix string, for example 12345678|username, and your password.

   1. This username and password is used to log in to registry.redhat.io.

      Note

      There are tabs available on the Token Information page that show you how to use the authentication token. For example, the Token Information tab shows the username in the format 12345678|username and the password string below it.

Procedure

1. From a terminal session log in to OpenShift as the cluster administrator:

   oc login

2. Select your project, or create a new project:

   oc project <project_name>

   Note

   When the 3scale deployment on OpenShift has been successful, your login and credentials will work.

Procedure

1. If you are not already logged in, log in to OpenShift:

   oc login

   1. Using the oc patch command, specify the secret type where system-smtp is the name of the secret, followed by the -p option, and write the new values in JSON for the following variables:

      Variable	Description
      address	Allows you to specify a remote mail server as a relay
      username	Specify your mail server username
      password	Specify your mail server password
      domain	Specify a HELO domain
      port	Specify the port on which the mail server is listening for new connections
      authentication	Specify the authentication type of your mail server. Allowed values: plain (sends the password in the clear), login (send password Base64 encoded), or cram_md5 (exchange information and a cryptographic Message Digest 5 algorithm to hash important information)
      openssl.verify.mode	Specify how OpenSSL checks certificates when using TLS. Allowed values: none or peer.

      Example

      oc patch secret system-smtp -p '{"stringData":{"address":"<your_address>"}}'
      oc patch secret system-smtp -p '{"stringData":{"username":"<your_username>"}}'
      oc patch secret system-smtp -p '{"stringData":{"password":"<your_password>"}}'

2. After you have set the secret variables, redeploy the system-app and system-sidekiq pods:

   oc rollout latest dc/system-app
   oc rollout latest dc/system-sidekiq

3. Check the status of the rollout to ensure it has finished:

   oc rollout status dc/system-app
   oc rollout status dc/system-sidekiq

Procedure

1. Create an access token with the following configurations:

   • Scoped to Account Management API
   • Having read-only access

2. Log in to your APIcast cluster:

   oc login

3. Create a secret that allows APIcast to communicate with 3scale. Specify the create secret and apicast-configuration-url-secret parameters with the access token, tenant name, and wildcard domain of your 3scale deployment:

   oc create secret generic apicast-configuration-url-secret --from-literal=password=https://<ACCESS_TOKEN>@<TENANT_NAME>-admin.<WILDCARD_DOMAIN>

   Note

   TENANT_NAME is the name under the root that the Admin Portal will be available with. The default value for TENANT_NAME is 3scale. If you used a custom value in your 3scale deployment, you must use that value here.

4. Import the APIcast template using the oc new-app command, specifying the --file option with the apicast.yml file:

   oc new-app --file /opt/amp/templates/apicast.yml

   Note

   First install the APIcast template as described in Configuring nodes and entitlements.

Procedure

1. Create an access token with the following configurations:

   • Scoped to Account Management API
   • Having read-only access

2. Log in to your APIcast cluster:

   oc login

3. Create a secret that allows APIcast to communicate with 3scale. Specify the create secret and apicast-configuration-url-secret parameters with the access token, tenant name, and wildcard domain of your 3scale deployment:

   oc create secret generic apicast-configuration-url-secret --from-literal=password=https://<ACCESS_TOKEN>@<TENANT_NAME>-admin.<WILDCARD_DOMAIN>

   Note

   TENANT_NAME is the name under the root that the Admin Portal will be available with. The default value for TENANT_NAME is 3scale. If you used a custom value in your 3scale deployment, you must use that value.

4. Deploy APIcast on a different OpenShift cluster using the oc new-app command. Specify the --file option and the to path to your apicast.yml file:

   oc new-app --file /path/to/file/apicast.yml

Procedure

1. If not already logged in, log in to your OpenShift cluster:

   oc login

3. Click Create APIManager.

4. Clear the sample content and add the following YAML definitions to the editor, then click Create.

   • Before 3scale 2.8, you could configure the automatic addition of replicas by setting the highAvailability field to true. From 3scale 2.8, the addition of replicas is controlled through the replicas field in the APIManager CR as shown in the following example.

     Note

     The wildcardDomain parameter can be any desired name you wish to give that resolves to an IP address, which is a valid DNS domain.

   • APIManager CR with minimum requirements:

     apiVersion: apps.3scale.net/v1alpha1
     kind: APIManager
     metadata:
       name: apimanager-sample
     spec:
       wildcardDomain: example.com

   • APIManager CR with replicas configured:

     apiVersion: apps.3scale.net/v1alpha1
     kind: APIManager
     metadata:
       name: apimanager-sample
     spec:

           replicas: 1
       wildcardDomain: example.com

1. Run the following commands to get the Admin Portal credentials:

   oc get secret system-seed -o json | jq -r .data.ADMIN_USER | base64 -d
   oc get secret system-seed -o json | jq -r .data.ADMIN_PASSWORD | base64 -d

   1. Log in as the Admin Portal administrator to verify these credentials are working.

2. Run the following commands to get the Master Admin Portal credentials:

   oc get secret system-seed -o json | jq -r .data.MASTER_USER | base64 -d
   oc get secret system-seed -o json | jq -r .data.MASTER_PASSWORD | base64 -d

   1. Log in as the Master Admin Portal administrator to verify these credentials are working.

   # oc get pvc
   NAME                    STATUS    VOLUME    CAPACITY   ACCESSMODES   AGE
   backend-redis-storage   Bound     vol003    100Gi      RWO,RWX       4d
   mysql-storage           Bound     vol006    100Gi      RWO,RWX       4d
   system-redis-storage    Bound     vol008    100Gi      RWO,RWX       4d
   system-storage          Bound     vol004    100Gi      RWO,RWX       4d

2. Stop the deployment of the system-mysql pod by clicking cancel deployment in the OpenShift UI.
3. Delete everything under the MySQL path to clean the volume.
4. Start a new system-mysql deployment.

Procedure

1. Type the following command to verify the configuration of your container registry authentication:

   $ oc get secret

   • If your secret exists, you will see the following output in the terminal:

     threescale-registry-auth          kubernetes.io/dockerconfigjson        1         4m9s

   • However, if you do not see the output, you must do the following:
2. Use the credentials you previously set up while Creating a registry service account to create your secret.
3. Use the steps in Configuring registry authentication in OpenShift, replacing <your-registry-service-account-username> and <your-registry-service-account-password> in the oc create secret command provided.

4. Generate the threescale-registry-auth secret in the same namespace as the APIManager resource. You must run the following inside the <project-name>:

   oc project <project-name>
   oc create secret docker-registry threescale-registry-auth \
     --docker-server=registry.redhat.io \
     --docker-username="<your-registry-service-account-username>" \
     --docker-password="<your-registry-service-account-password>"
     --docker-email="<email-address>"

5. Delete and recreate the APIManager resource:

   $ oc delete -f apimanager.yaml
   apimanager.apps.3scale.net "example-apimanager" deleted
   
   $ oc create -f apimanager.yaml
   apimanager.apps.3scale.net/example-apimanager created

Verification

1. Type the following command to confirm that deployments have a status of Starting or Ready. The pods then begin to spawn:

   $ oc describe apimanager
   (...)
   Status:
     Deployments:
       Ready:
         apicast-staging
         system-memcache
         system-mysql
         system-redis
         zync
         zync-database
         zync-que
       Starting:
         apicast-production
         backend-cron
         backend-worker
         system-sidekiq
         system-sphinx
       Stopped:
         backend-listener
         backend-redis
         system-app

2. Type the following command to see the status of each pod:

   $ oc get pods
   NAME                               READY   STATUS             RESTARTS   AGE
   3scale-operator-66cc6d857b-sxhgm   1/1     Running            0          17h
   apicast-production-1-deploy        1/1     Running            0          17m
   apicast-production-1-pxkqm         0/1     Pending            0          17m
   apicast-staging-1-dbwcw            1/1     Running            0          17m
   apicast-staging-1-deploy           0/1     Completed          0          17m
   backend-cron-1-deploy              1/1     Running            0          17m

Procedure

1. The directories used for the persistent volumes MUST have the write permissions for the root group. Having read-write permissions for the root user is not enough as the MySQL service runs as a different user in the root group. Execute the following command as the root user:

   chmod -R g+w /path/for/pvs

2. Execute the following command to prevent SElinux from blocking access:

   chcon -Rt svirt_sandbox_file_t /path/for/pvs
