Not able to delete kubernetes cluster in GKE

Question

I'm getting this error when deleting a cluster from GKE.

Google Compute Engine: The subnetwork resource 'projects/abc-cluster-abc/regions/us-east1/subnetworks/sub-network-1' is already being used by 'projects/abc-cluster-abc/zones/us-east1-d/instances/gke-qa-cluster-pool-1-abc-xyz'

How to delete it? Please help us out.

Answer 1

You can delete a GKE cluster by 2 simple ways

                  1. BY gcloud
                  2. BY Console

1.

            gcloud container clusters delete [CLUSTER_NAME]

2.

--> By choosing the cluster to select your gke cluster and select shutdown to Delete(or)Remove

Answer 2

First, you’ll need to delete subnetwork “sub-network-1” as it’s used by node “gke-qa-cluster-pool-1-abc-xyz”.

Then you’ll be able to delete your cluster.
