Chapter 5. Configuring proxy support in Operator Lifecycle Manager

Procedure

1. Navigate in the web console to the Operators OperatorHub page.
2. Select the Operator and click Install.

3. On the Create Operator Subscription page, modify the Subscription object’s YAML to include one or more of the following environment variables in the spec section:

   • HTTP_PROXY
   • HTTPS_PROXY
   • NO_PROXY

   For example:

   Subscription object with proxy setting overrides

   apiVersion: operators.coreos.com/v1alpha1
   kind: Subscription
   metadata:
     name: etcd-config-test
     namespace: openshift-operators
   spec:
     config:
       env:
       - name: HTTP_PROXY
         value: test_http
       - name: HTTPS_PROXY
         value: test_https
       - name: NO_PROXY
         value: test
     channel: clusterwide-alpha
     installPlanApproval: Automatic
     name: etcd
     source: community-operators
     sourceNamespace: openshift-marketplace
     startingCSV: etcdoperator.v0.9.4-clusterwide

   OLM handles these environment variables as a unit; if at least one of them is set, all three are considered overridden and the cluster-wide defaults are not used for the subscribed Operator’s Deployments.

4. Click Subscribe to make the Operator available to the selected namespaces.

5. After the Operator’s CSV appears in the relevant namespace, you can verify that custom proxy environment variables are set in the Deployment. For example, using the CLI:

   $ oc get deployment -n openshift-operators etcd-operator -o yaml | grep -i "PROXY" -A 2
   
           - name: HTTP_PROXY
             value: test_http
           - name: HTTPS_PROXY
             value: test_https
           - name: NO_PROXY
             value: test
           image: quay.io/coreos/etcd-operator@sha256:66a37fd61a06a43969854ee6d3e21088a98b93838e284a6086b13917f96b0d9c

Procedure

1. Create an empty ConfigMap in the namespace where your Operator’s Subscription exists and include the following label:

   apiVersion: v1
   kind: ConfigMap
   metadata:
     name: trusted-ca 

   1

   
     labels:
       config.openshift.io/inject-trusted-cabundle: "true" 

   2

   1

   Name of the ConfigMap.

   2

   Requests the Cluster Network Operator to inject the merged bundle.

   After creating this ConfigMap, the ConfigMap is immediately populated with the certificate contents of the merged bundle.

2. Update your Operator’s Subscription object to include a spec.config section that mounts the trusted-ca ConfigMap as a volume to each container within a Pod that requires a custom CA:

   kind: Subscription
   metadata:
     name: my-operator
   spec:
     package: etcd
     channel: alpha
     config: 

   1

   
     - selector:
         matchLabels:
           <labels_for_pods> 

   2

   
       volumes: 

   3

   
       - name: trusted-ca
         configMap:
           name: trusted-ca
           items:
             - key: ca-bundle.crt 

   4

   
               path: tls-ca-bundle.pem 

   5

   
       volumeMounts: 

   6

   
       - name: trusted-ca
         mountPath: /etc/pki/ca-trust/extracted/pem
         readOnly: true

   Copy to Clipboard Toggle word wrap

   1

   Add a config section if it does not exist.

   2

   Specify labels to match Pods that are owned by the Operator.

   3

   Create a trusted-ca volume.

   4

   ca-bundle.crt is required as the ConfigMap key.

   5

   tls-ca-bundle.pem is required as the ConfigMap path.

   6

   Create a trusted-ca volume mount.
