Chapter 9. Using a cluster-scoped Argo Rollouts instance to manage rollout resources

Procedure

1. In the Administrator perspective of the web console, navigate to Operators Installed Operators Red Hat OpenShift GitOps Subscription.
2. Click the Actions list and then click Edit Subscription.

3. On the openshift-gitops-operator Subscription details page, under the YAML tab, edit the Subscription YAML file by setting the CLUSTER_SCOPED_ARGO_ROLLOUTS_NAMESPACES environment variable to a comma-separated list of namespaces:

   Example configuring the CLUSTER_SCOPED_ARGO_ROLLOUTS_NAMESPACES environment variable:

   apiVersion: operators.coreos.com/v1alpha1
   kind: Subscription
   metadata:
     name: openshift-gitops-operator
   spec:
     config:
       env:
         - name: NAMESPACE_SCOPED_ARGO_ROLLOUTS
           value: "false"
         - name: CLUSTER_SCOPED_ARGO_ROLLOUTS_NAMESPACES
           value: "namespace1,namespace2,namespace3"

   where:

   spec.config.env[].value (NAMESPACE_SCOPED_ARGO_ROLLOUTS)

   Specify this value to enable or disable the cluster-scoped installation. Set the value to 'false' to enable cluster-scoped installation. Set to 'true' to enable namespace-scoped installation. If this value is empty, the operator defaults to false.

   spec.config.env[].value (CLUSTER_SCOPED_ARGO_ROLLOUTS_NAMESPACES)

   Specifies a comma-separated list of namespaces that can host a cluster-scoped Argo Rollouts instance. For example test-123-cluster-scoped,test-456-cluster-scoped.

4. Click Save and Reload.

1. In the Administrator perspective, navigate to Workloads Pods.
2. Locate the openshift-gitops-operator-controller-manager pod and verify that it has a recent restart time.

3. Verify that the Argo Rollouts controller is managing the specified namespaces:

   1. Navigate to the namespace where you created the RolloutManager CR.
   2. Click the argo-rollouts- pod, and then click the Logs tab.
   3. Confirm that the logs show the controller is watching the namespaces you specified in CLUSTER_SCOPED_ARGO_ROLLOUTS_NAMESPACES.
