Question

An open-data cluster needs a sustained operational change to kube-proxy’s ConfigMap as part of lifecycle maintenance. What does this illustrate about cluster lifecycle work?

Accepted Answer

Lifecycle management includes safely updating core addon configuration such as kube-proxy or CoreDNS—not only binary upgrades. — Keeping a cluster healthy isn’t only version bumps—it’s also tending the little system services that make networking and DNS tick. Editing kube-proxy’s ConfigMap (carefully) is normal ops, same family as CoreDNS tweaks. Treat addons like living machinery, not museum pieces.

Answer

Core addons are immutable after kubeadm init and can never be reconfigured.

Answer

kube-proxy ConfigMaps are owned exclusively by each application Deployment and never by cluster ops.

Answer

Changing kube-proxy settings requires replacing etcd with a new empty data directory.
