Deleting Clusters

Page last updated:

This topic describes how to delete a Kubernetes cluster deployed by VMware Enterprise PKS. Running the pks delete-cluster command automatically deletes all cluster objects.

If you are using Enterprise PKS with NSX-T, see vSphere with NSX-T Cluster Objects for a list of vSphere and NSX-T objects that will be deleted as part of the cluster deletion process.

Delete Cluster

Follow the steps below to delete a cluster using the PKS CLI.

1. On the command line, run the following command to log in:

   pks login -a PKS-API -u USERNAME -k
   

   Where:
   • PKS-API is the domain name for the PKS API that you entered in Ops Manager > Enterprise PKS > PKS API > API Hostname (FQDN). For example, api.pks.example.com.
   • USERNAME is your user name.
     
     See Logging in to Enterprise PKS for more information about the pks login command.

     Note: If your operator has configured Enterprise PKS to use a SAML identity provider, you must include an additional SSO flag to use the above command. For information about the SSO flags, see the section for the above command in PKS CLI. For information about configuring SAML, see Connecting Enterprise PKS to a SAML Identity Provider

2. Run pks delete-cluster CLUSTER-NAME to delete a cluster. Replace CLUSTER-NAME with the unique name for your cluster. For example:

   $ pks delete-cluster my-cluster

3. Confirm cluster deletion by entering y, or cancel cluster deletion by entering n.
   
   For example:

   Are you sure you want to delete cluster my-cluster? (y/n)

Verify Cluster Deletion

Follow the steps below to verify cluster deletion using the PKS CLI.

1. To verify cluster deletion, run pks cluster CLUSTER-NAME. Replace CLUSTER-NAME with the unique name for your cluster.
   
   For example:

   $ pks cluster my-cluster
   Name:                     my-cluster
   Plan Name:                small
   UUID:                     106aabc7-5ecb-4c54-a800-a32eef57a593
   Last Action:              DELETE
   Last Action State:        in progress
   Last Action Description:  Instance deletion in progress
   Kubernetes Master Host:   my-cluster.pks.local
   Kubernetes Master Port:   8443
   Worker Nodes:             3
   Kubernetes Master IP(s):  10.196.219.88
   Network Profile Name:
   

   While Enterprise PKS is deleting the cluster, the value for Last Action Description is Instance deletion in progress.

2. Continue running the pks cluster CLUSTER-NAME command to track cluster deletion. The cluster is deleted when the CLI returns Error: Cluster CLUSTER-NAME not found.

3. Run pks clusters. The cluster you deleted should not appear in the list of Enterprise PKS clusters.

   Note: If the cluster is not deleted, see Cluster Deletion Fails in Troubleshooting.

Delete Cluster without Prompt

If you do not want the PKS CLI to prompt you to confirm cluster deletion, use the --non-interactive flag.

For example:

$ pks delete-cluster my-cluster --non-interactive

Note: If you use the --non-interactive flag to delete multiple clusters, delete each cluster one by one. Do not create a script that deletes multiple clusters using the --non-interactive flag. If you do, the BOSH Director may hang and become unusable until you log in to BOSH and cancel each deletion task.
