Public-works brings up a new kubeadm cluster but forgets to install a CNI plugin. What typically happens to workloads?
Select an answer to reveal the explanation.
Short Explanation
Without a CNI, the cluster is like a building with rooms but no hallway wiring—Pods show up on the work order (Pending / not Ready) and never get a usable network. etcd does not hand out Pod IPs. Install the CNI early.
Full Explanation
Kubernetes expects a CNI plugin to configure Pod network interfaces and IPAM. If none is installed, Pods commonly remain Pending with network-related events or never become Ready. Control-plane auth and etcd do not substitute for node Pod networking.
