You can install the NBDE Tang Server Operator from the OperatorHub using the CLI.

Prerequisites

  • You must have cluster-admin privileges on an OpenShift Container Platform cluster.

  • You have installed the OpenShift CLI (oc).

Procedure

  1. Use the following command to list available Operators on OperatorHub, and limit the output to Tang-related results:

    $ oc get packagemanifests -n openshift-marketplace | grep tang
    Example output
    tang-operator           Red Hat

    In this case, the corresponding packagemanifest name is tang-operator.

  2. Create a Subscription object YAML file to subscribe a namespace to the NBDE Tang Server Operator, for example, tang-operator.yaml:

    Example subscription YAML for tang-operator
    apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: tang-operator
  namespace: openshift-operators
spec:
  channel: stable (1)
  installPlanApproval: Automatic
  name: tang-operator (2)
  source: redhat-operators (3)
  sourceNamespace: openshift-marketplace (4)
    1 Specify the channel name from where you want to subscribe the Operator.
    2 Specify the name of the Operator to subscribe to.
    3 Specify the name of the CatalogSource that provides the Operator.
    4 The namespace of the CatalogSource. Use openshift-marketplace for the default OperatorHub CatalogSources.

  3. Apply the Subscription to the cluster:

    $ oc apply -f tang-operator.yaml
Verification

  • Check that the NBDE Tang Server Operator controller runs in the openshift-operators namespace:

    $ oc -n openshift-operators get pods
    Example output
    NAME                                                READY   STATUS    RESTARTS   AGE
