Chapter 6. Known issues

Workaround one: Set the KUBERNETES_MASTER environment variable

1. Display the address of the Kubernetes master node of your OpenShift Container Platform cluster:

   oc cluster-info
   Kubernetes master is running at MASTER-ADDRESS
   # ...

   Copy to Clipboard Toggle word wrap

   Copy the address of the master node.

2. List all Operator subscriptions:

   oc get subs -n OPERATOR-NAMESPACE

   Copy to Clipboard Toggle word wrap

3. Edit the Subscription resource for AMQ Streams:

   oc edit sub amq-streams -n OPERATOR_NAMESPACE

   Copy to Clipboard Toggle word wrap

4. In spec.config.env, add the KUBERNETES_MASTER environment variable, set to the address of the Kubernetes master node. For example:

   apiVersion: operators.coreos.com/v1alpha1
   kind: Subscription
   metadata:
     name: amq-streams
     namespace: OPERATOR-NAMESPACE
   spec:
     channel: amq-streams-1.7.x
     installPlanApproval: Automatic
     name: amq-streams
     source: mirror-amq-streams
     sourceNamespace: openshift-marketplace
     config:
       env:
       - name: KUBERNETES_MASTER
         value: MASTER-ADDRESS

   Copy to Clipboard Toggle word wrap
5. Save and exit the editor.

6. Check that the Subscription was updated:

   oc get sub amq-streams -n OPERATOR-NAMESPACE

   Copy to Clipboard Toggle word wrap

7. Check that the Cluster Operator Deployment was updated to use the new environment variable:

   oc get deployment CLUSTER-OPERATOR-DEPLOYMENT-NAME

   Copy to Clipboard Toggle word wrap

Workaround two: Disable hostname verification

1. List all Operator subscriptions:

   oc get subs -n OPERATOR-NAMESPACE

   Copy to Clipboard Toggle word wrap

2. Edit the Subscription resource for AMQ Streams:

   oc edit sub amq-streams -n OPERATOR_NAMESPACE

   Copy to Clipboard Toggle word wrap

3. In spec.config.env, add the KUBERNETES_DISABLE_HOSTNAME_VERIFICATION environment variable, set to true. For example:

   apiVersion: operators.coreos.com/v1alpha1
   kind: Subscription
   metadata:
     name: amq-streams
     namespace: OPERATOR-NAMESPACE
   spec:
     channel: amq-streams-1.7.x
     installPlanApproval: Automatic
     name: amq-streams
     source: mirror-amq-streams
     sourceNamespace: openshift-marketplace
     config:
       env:
       - name: KUBERNETES_DISABLE_HOSTNAME_VERIFICATION
         value: "true"

   Copy to Clipboard Toggle word wrap
4. Save and exit the editor.

5. Check that the Subscription was updated:

   oc get sub amq-streams -n OPERATOR-NAMESPACE

   Copy to Clipboard Toggle word wrap

6. Check that the Cluster Operator Deployment was updated to use the new environment variable:

   oc get deployment CLUSTER-OPERATOR-DEPLOYMENT-NAME

   Copy to Clipboard Toggle word wrap

1. Edit the spec properties for the KafkaBridge custom resource.

   Add the discovery.3scale.net: true template property to your existing configuration:

   Example template configuration for Kafka Bridge

   apiVersion: kafka.strimzi.io/v1beta1
   kind: KafkaBridge
   metadata:
     name: KAFKA-BRIDGE-NAME
   spec:
     replicas: 1
     bootstrapServers: my-cluster-kafka-bootstrap:9092
     http:
       port: 8080
     template:
       apiService:
         metadata:
           labels:
             discovery.3scale.net: true 

   1

   
   # ...

   Enables 3scale to discover the Kafka Bridge service.

2. Create or update the custom resource:

   kubectl apply -f KAFKA-BRIDGE-CONFIG-FILE
