Chapter 2. 3scale template-based upgrade guide: from 2.8 to 2.9.1

This section contains information about upgrading Red Hat 3scale API Management from version 2.8 to 2.9.1, in a template-based deployment.

Important considerations

  • In order to understand the required conditions and procedure, read the entire upgrade guide before applying the listed steps. The upgrade process disrupts the provision of the service until the procedure finishes. Due to this disruption, make sure to have a maintenance window.
  • If your 3scale template-based installation runs with Oracle Database, refer to the Support to Oracle Databases in the 3scale 2.9.1 Release Notes.

2.1. Prerequisites to perform the upgrade
Copiar enlace

This section describes the required configurations, tasks and tools to upgrade 3scale from 2.8 to 2.9.1 in a template-based installation.

2.1.1. Configurations
Copiar enlace

  • 3scale supports upgrade paths from 2.8 to 2.9.1 with templates on OpenShift 3.11.

2.1.2. Preliminary tasks
Copiar enlace

  • Ensure your OpenShift CLI tool is configured in the same project where 3scale is deployed.
  • Perform a backup of the database you are using with 3scale. The procedure of the backup is specific to each database type and setup.

2.1.3. Tools
Copiar enlace

You need these tools to perform the upgrade:

  • 3scale 2.8 deployed with templates in an OpenShift 3.11 project.
  • Bash shell: To run the commands detailed in the upgrade procedure.
  • base64: To encode and decode secret information.
  • jq: For JSON transformation purposes.

2.2. Upgrading from 2.8 to 2.9.1 in a template-based installation
Copiar enlace

Follow the procedure described in this section to upgrade 3scale 2.8 to 2.9.1 in a template-based installation.

To start with the upgrade, go to the project where 3scale is deployed. 

$ oc project <3scale-project>

Then, follow these steps in this order:

  1. Section 2.2.1, “Creating a backup of the 3scale project”
  2. Section 2.2.2, “Removing the BASE_URL field”
  3. Section 2.2.3, “Updating 3scale version number”
  4. Section 2.2.4, “Upgrading 3scale images”

2.2.1. Creating a backup of the 3scale project

Previous step

None.

Current step

This step lists the actions necessary to create a backup of the 3scale project.

  1. Depending on the database used with 3scale, set ${SYSTEM_DB} with one of the following values:

    • If the database is MySQL, SYSTEM_DB=system-mysql.
    • If the database is PostgreSQL, SYSTEM_DB=system-postgresql.

  2. Create a back-up file with the existing DeploymentConfigs: 

    THREESCALE_DC_NAMES="apicast-production apicast-staging backend-cron backend-listener backend-redis backend-worker system-app system-memcache ${SYSTEM_DB} system-redis system-sidekiq system-sphinx zync zync-database zync-que"

for component in ${THREESCALE_DC_NAMES}; do oc get --export -o yaml dc ${component} > ${component}_dc.yml ; done
    Copy to Clipboard Toggle word wrap

  3. Backup all existing OpenShift resources in the project that are exported through the export all command: 

    oc get -o yaml --export all > threescale-project-elements.yaml
    Copy to Clipboard Toggle word wrap

  4. Create a back-up file with the additional elements that are not exported with the export all command: 

    for object in rolebindings serviceaccounts secrets imagestreamtags cm rolebindingrestrictions limitranges resourcequotas pvc templates cronjobs statefulsets hpa deployments replicasets poddisruptionbudget endpoints
do
  oc get -o yaml --export $object > $object.yaml
done

Previous step

Confirm that all the image URLs of the DeploymentConfigs contain the new image registry URLs with a hash added at the end of each URL address: 

THREESCALE_DC_NAMES="apicast-production apicast-staging backend-cron backend-listener backend-redis backend-worker system-app system-memcache system-mysql system-redis system-sidekiq system-sphinx zync zync-database zync-que"
for component in ${THREESCALE_DC_NAMES}; do echo -n "${component} image: " && oc get dc $component -o json | jq .spec.template.spec.containers[0].image ; done

Next step

None. After you have performed all the listed steps, 3scale upgrade from 2.8 to 2.9.1 in a template-based deployment is now complete.

This section explains how to upgrade Red Hat 3scale API Management when you are using a 3scale system image with an Oracle Database, in a template-based installation with OpenShift 3.11.

Prerequisites

A 3scale installation with the Oracle Database. See Setting up your 3scale system image with an Oracle Database.

To upgrade your 3scale system image with an Oracle Database in a template-based installation, perform one of the procedures below according to your database version:

2.3.1. Upgrading 3scale with Oracle 19c
Copiar enlace

This procedure guides you through changing from Oracle Database 12c to Oracle Database 19c, for 3scale 2.9.1 from an existing 3scale 2.8 installation.

IMPORTANT: Loss of connection to the database can potentially corrupt 3scale. Make a backup before proceeding to perform the upgrade. See the official Oracle Database documentation: Oracle Database Backup and Recovery User’s Guide.

Prerequisites

  • A 3scale 2.8 installation

  • An Oracle Database 12c installation.

Procedure

  1. Scale 3scale down to 0 (zero), with the following considerations:

    1. The 3scale connection to the database fails because it is disconnected from Oracle 12c.

  2. Upgrade Oracle 12c to Oracle 19c.

    1. To perform the upgrade, follow the official Oracle Database Upgrade Guide.

  3. Clone the OpenShift Templates for 3scale 2.9.1 

    $ git clone --branch 2.9.1.GA https://github.com/3scale/3scale-amp-openshift-templates.git
    Copy to Clipboard Toggle word wrap
  4. Place your Oracle Database Instant Client Package files into the 3scale-amp-openshift-templates/amp/system-oracle/oracle-client-files directory.

  5. Run the oc process command with the -f option and specify the build.yml OpenShift template: 

    $ oc process -f build.yml | oc apply -f -

  6. Enter the oc start-build command to build the new system image: 

    $ oc start-build 3scale-amp-system-oracle --from-dir=.
    Copy to Clipboard Toggle word wrap

  7. Wait until the build completes. To see the state of the build, run the following command: 

    $ oc get build <build-name> -o jsonpath="{.status.phase}"
    Copy to Clipboard Toggle word wrap
    1. Wait until the build is in a Complete state.

2.3.2. Upgrading 3scale with Oracle 12c
