If a global proxy is configured on the OpenShift Container Platform cluster, Operator Lifecycle Manager (OLM) automatically configures Operators that it manages with the cluster-wide proxy. However, you can also configure installed Operators to override the global proxy or inject a custom CA certificate.

Overriding proxy settings of an Operator

If a cluster-wide egress proxy is configured, Operators running with Operator Lifecycle Manager (OLM) inherit the cluster-wide proxy settings on their deployments. Cluster administrators can also override these proxy settings by configuring the subscription of an Operator.

Operators must handle setting environment variables for proxy settings in the pods for any managed Operands.

  • Access to an OpenShift Container Platform cluster using an account with cluster-admin permissions.

  1. Navigate in the web console to the Operators → OperatorHub page.

  2. Select the Operator and click Install.

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



    • NO_PROXY

    For example:

    Subscription object with proxy setting overrides
    apiVersion: operators.coreos.com/v1alpha1
    kind: Subscription
      name: etcd-config-test
      namespace: openshift-operators
        - 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

    These environment variables can also be unset using an empty value to remove any previously set cluster-wide or custom proxy settings.

    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 deployments of the subscribed Operator.

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

  5. After the CSV for the Operator 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
    Example output
            - 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

Injecting a custom CA certificate

When a cluster administrator adds a custom CA certificate to a cluster using a config map, the Cluster Network Operator merges the user-provided certificates and system CA certificates into a single bundle. You can inject this merged bundle into your Operator running on Operator Lifecycle Manager (OLM), which is useful if you have a man-in-the-middle HTTPS proxy.

  • Access to an OpenShift Container Platform cluster using an account with cluster-admin permissions.

  • Custom CA certificate added to the cluster using a config map.

  • Desired Operator installed and running on OLM.

  1. Create an empty config map in the namespace where the subscription for your Operator exists and include the following label:

    apiVersion: v1
    kind: ConfigMap
      name: trusted-ca (1)
        config.openshift.io/inject-trusted-cabundle: "true" (2)
    1 Name of the config map.
    2 Requests the Cluster Network Operator to inject the merged bundle.

    After creating this config map, it is immediately populated with the certificate contents of the merged bundle.

  2. Update your the Subscription object to include a spec.config section that mounts the trusted-ca config map as a volume to each container within a pod that requires a custom CA:

    kind: Subscription
      name: my-operator
      package: etcd
      channel: alpha
      config: (1)
            <labels_for_pods> (2)
        volumes: (3)
        - name: trusted-ca
            name: trusted-ca
              - 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
    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 config map key.
    5 tls-ca-bundle.pem is required as the config map path.
    6 Create a trusted-ca volume mount.
