Delete Node Pools

Delete Node Pools

Deleting a node pool deletes the Kubernetes nodes and the underlying infrastructure. DKP drains all nodes prior to deletion and reschedules the pods running on those nodes.

To delete a node pool from a managed cluster, run the command:

dkp delete nodepool ${NODEPOOL_NAME} --cluster-name=${CLUSTER_NAME}

Here, example is the node pool to be deleted.

The expected output is similar to the following example, indicating the node pool is being deleted:

INFO[2021-07-28T17:14:26-07:00] Running nodepool delete command         Nodepool=example clusterName=d2iq-e2e-cluster-1 managementClusterKubeconfig= namespace=default src="nodepool/delete.go:80"

Deleting an invalid node pool results in output similar to this example command output:

dkp delete nodepool ${CLUSTER_NAME}-md-invalid --cluster-name=${CLUSTER_NAME}

INFO[2021-07-28T17:11:44-07:00] Running nodepool delete command               Nodepool=demo-cluster-md-invalid clusterName=d2iq-e2e-cluster-1 managementClusterKubeconfig= namespace=default src="nodepool/delete.go:80"
