Red Hat OpenShift Container Platform

Installing the NBDE Tang Server Operator using CLI

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

Prerequisites

You must have cluster-admin privileges on an Red Hat OpenShift Container Platform cluster.
You have installed the OpenShift CLI (oc).

Procedure

Use the following command to list available Operators in the software catalog, 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.

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 
  installPlanApproval: Automatic
  name: tang-operator 
  source: redhat-operators 
  sourceNamespace: openshift-marketplace

	Specify the channel name from where you want to subscribe the Operator.
	Specify the name of the Operator to subscribe to.
	Specify the name of the CatalogSource that provides the Operator.
	The namespace of the CatalogSource. Use `openshift-marketplace` for the default software catalog sources.

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
