OpenShift Container Platform

Installing the Topology Aware Lifecycle Manager by using the CLI

You can use the OpenShift CLI (oc) to install the Topology Aware Lifecycle Manager (TALM).

Prerequisites

Install the OpenShift CLI (oc).
Install the latest version of the RHACM Operator.
TALM requires RHACM 2.9 or later.
Set up a hub cluster with disconnected registry.
Log in as a user with cluster-admin privileges.

Procedure

Create a Subscription CR:

Define the Subscription CR and save the YAML file, for example, talm-subscription.yaml:

apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: openshift-topology-aware-lifecycle-manager-subscription
  namespace: openshift-operators
spec:
  channel: "stable"
  name: topology-aware-lifecycle-manager
  source: redhat-operators
  sourceNamespace: openshift-marketplace

Create the Subscription CR by running the following command:
```
$ oc create -f talm-subscription.yaml
```

Verification

Verify that the installation succeeded by inspecting the CSV resource:

$ oc get csv -n openshift-operators

Example output
