Chapter 13. Destroying a hosted cluster

Procedure

1. Delete the managed cluster resource on multicluster engine Operator by running the following command:

   $ oc delete managedcluster <hosted_cluster_name> 1

   1

   Replace <hosted_cluster_name> with the name of your cluster.

2. Delete the hosted cluster and its backend resources by running the following command:

   $ hcp destroy cluster aws  \
     --name <hosted_cluster_name> \1
     --infra-id <infra_id> \2
     --role-arn <arn_role> \3
     --sts-creds <path_to_sts_credential_file> \4
     --base-domain <basedomain> 5

   1

   Specify the name of your hosted cluster, for instance, example.

   2

   Specify the infrastructure name for your hosted cluster.

   3

   Specify the Amazon Resource Name (ARN), for example, arn:aws:iam::820196288204:role/myrole.

   4

   Specify the path to your AWS Security Token Service (STS) credentials file, for example, /home/user/sts-creds/sts-creds.json.

   5

   Specify your base domain, for example, example.com.

   Important

   If your session token for AWS Security Token Service (STS) is expired, retrieve the STS credentials in a JSON file named sts-creds.json by running the following command:

   $ aws sts get-session-token --output json > sts-creds.json

Procedure

1. In the console, click Infrastructure Clusters.
2. On the Clusters page, select the cluster that you want to destroy.
3. In the Actions menu, select Destroy clusters to remove the cluster.

Procedure

1. Delete the managed cluster resource on multicluster engine Operator by running the following command:

   $ oc delete managedcluster <hosted_cluster_name>

2. Delete the hosted cluster and its backend resources by running the following command:

   $ hcp destroy cluster kubevirt --name <hosted_cluster_name>

Procedure

1. Scale the NodePool object to 0 nodes by running the following command:

   $ oc -n <hosted_cluster_namespace> scale nodepool <nodepool_name> --replicas 0

   Important

   If the compute nodes are not detached from the hosted cluster or are stuck in the Notready state, delete the compute nodes manually by running the following command:

   $ oc --kubeconfig <hosted_cluster_name>.kubeconfig delete node <compute_node_name>

2. Verify the status of the compute nodes by entering the following command:

   $ oc --kubeconfig <hosted_cluster_name>.kubeconfig get nodes

   After the compute nodes are detached from the hosted cluster, the status of the agents is changed to auto-assign.

3. Delete the agents from the cluster by running the following command:

   $ oc -n <hosted_control_plane_namespace> delete agent <agent_name>

   Note

   You can delete the virtual machines that you created as agents after you delete the agents from the cluster.

4. Destroy the hosted cluster by running the following command:

   $ hcp destroy cluster agent --name <hosted_cluster_name> --namespace <hosted_cluster_namespace>

Procedure

1. In the console, click Infrastructure Clusters.
2. On the Clusters page, select the cluster that you want to destroy.
3. In the Actions menu, select Destroy clusters to remove the cluster.
