In my earlier post, I have shown the steps to attach/register TKG clusters using TMC CLI, now let me explain the process of detaching and deregistering the clusters using TMC Console.
Detach the workload cluster from TMC Console
In TMC Console: Clusters > select the cluster capv-workload > Actions (can be located in top right corner) > Detach
provide the name : capv-workload > DETACH
Verify the pod status, should take few mins to complete
# Get the admin credentials of the workload cluster. In this case, capv-workload is workload cluster:
$ tanzu cluster kubeconfig get capv-workload --admin
