This topic describes how to delete a Kubernetes cluster deployed by VMware Tanzu Kubernetes Grid Integrated Edition. Running the
tkgi delete-cluster command automatically deletes all cluster objects.
If you are using Tanzu Kubernetes Grid Integrated Edition 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.
Follow the steps below to delete a cluster using the TKGI CLI.
On the command line, run the following command to log in:
tkgi login -a TKGI-API -u USERNAME -kWhere:
TKGI-APIis the domain name for the TKGI API that you entered in Ops Manager > Tanzu Kubernetes Grid Integrated Edition > TKGI API > API Hostname (FQDN). For example,
USERNAMEis your user name.
See Logging in to Tanzu Kubernetes Grid Integrated Edition for more information about the
Note: If your operator has configured Tanzu Kubernetes Grid Integrated Edition 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 TKGI CLI.

tkgi delete-cluster CLUSTER-NAMEto delete a cluster. Replace
CLUSTER-NAMEwith the unique name for your cluster. For example:
$ tkgi delete-cluster my-cluster
Confirm cluster deletion by entering
y, or cancel cluster deletion by entering
Are you sure you want to delete cluster my-cluster? (y/n)
Follow the steps below to verify cluster deletion using the TKGI CLI.
To verify cluster deletion, run
tkgi cluster CLUSTER-NAME. Replace
CLUSTER-NAMEwith the unique name for your cluster.

Continue running the
tkgi cluster CLUSTER-NAMEcommand to track cluster deletion. The cluster is deleted when the CLI returns

tkgi clusters. The cluster you deleted should not appear in the list of Tanzu Kubernetes Grid Integrated Edition clusters.
Note: If the cluster is not deleted, see Cluster Deletion Fails in Troubleshooting.
If you do not want the TKGI CLI to prompt you to confirm cluster deletion, use the
$ tkgi 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.
