Chapter 6. Installing the 3scale Operator on OpenShift

This documentation shows you how to:

  • Create a new project.
  • Deploy a Red Hat 3scale API Management instance.
  • Create the threescale-registry-auth secret in the project.
  • Install the 3scale operator through Operator Lifecycle Manager (OLM).
  • Deploy the custom resources once the operator has been deployed.

Prerequisites

Warning

Deploy the 3scale operator and custom resource definitions (CRDs) in a separate newly created, empty project. If you deploy them in an existing project containing infrastructure, it could alter or delete existing elements.

To install the 3scale operator on OpenShift, perform the steps outlined in the following sections:

6.1. Creating a new OpenShift project

This procedure explains how to create a new OpenShift project named 3scale-project. Replace this project name with your own.

Procedure

To create a new OpenShift project:

  • Indicate a valid name using alphanumeric characters and dashes. As an example, run the command below to create 3scale-project:

    oc new-project 3scale-project

This creates the new OpenShift project where the operator, the APIManager custom resource (CR), and the Capabilities custom resources will be installed. The operator manages the custom resources through OLM in that project.

6.2. Installing and configuring the 3scale operator using the OLM

Use OLM to install the 3scale Operator on an OpenShift Container Platform 4 cluster by using OperatorHub in the OpenShift Container Platform console.

Note

You must install and deploy the 3scale operator in the project that you defined in Creating a new OpenShift project.

Procedure

  1. In the OpenShift Container Platform console, log in using an account with administrator privileges.
  2. The menu structure depends on the version of OpenShift you are using:

    • For OCP 4.1, click Catalog > OperatorHub.
    • For OCP 4.2, click Operators > OperatorHub
  3. In the Filter by keyword box, type 3scale operator to find the 3scale operator.
  4. Click the 3scale operator. Information about the Operator is displayed.
  5. Read the information about the operator and click Install. The Create Operator Subscription page opens.
  6. On the Create Operator Subscription page, accept all of the default selections and click Subscribe.

    Note

    The operator will only be available in the specific single namespace on the cluster that you have selected.

    The 3scale-operator details page is displayed, where you can see the Subscription Overview.

  7. Confirm that the subscription upgrade status is shown as Up to date.
  8. Verify that the 3scale operator ClusterServiceVersion (CSV) is displayed, and the Status of the operator ultimately resolves to InstallSucceeded in the project you defined in Creating a new OpenShift project:

    • For OCP 4.1, click Catalog > Installed Operators.
    • For OCP 4.2, click Operators > Installed Operators. In this case, successful installation will register the APIManager CRD, and the CRDs related to the Capabilities functionality of the operator in the OpenShift API server.
  9. After successful installation, query the resource types defined by the CRDs via oc get.

    1. For example, to verify that the APIManager CRD has been correctly registered, execute the following command:

      oc get apimanagers
  10. You should see the following output:

    No resources found.
