Hello
Created my kubernetes cluster with:
kubeadm init --pod-network-cidr=10.244.0.0/16
When I create a deployment with Benjamin Muschko CKS materials pods are created in the specified network.
But there is no connectivity between the frontend and the backend pod.
I just discovered that services are still using the 10.96.0.0 network.
How can I correct this?
Any hints?
