How do I completely disable Kube DNS replication

Question

I don't need even a single replica. How do I completely disable Kube DNS replication on a GKE cluster?

Answer 1

You can completely disable Kube DNS. Kube DNS is required for workloads that resolve the DNS name of any dependent service. This includes public domain names and the names of cluster services.

To disable Kube DNS:

kubectl scale --replicas=0 deployment/kube-dns-autoscaler --namespace=kube-system kubectl scale --replicas=0 deployment/kube-dns --namespace=kube-system

To enable Kube DNS:

kubectl scale --replicas=1 deployment/kube-dns --namespace=kube-system

where --replicas=1 is your desired number of replicas.

To enable Kube DNS autoscaling:

kubectl scale --replicas=1 deployment/kube-dns-autoscaler --namespace=kube-system
