What is Kubernetes Node Readiness Controller?

It's a controller that uses custom node conditions to dynamically taint unready nodes, keeping pods off shaky infrastructure during bootstrap or ongoing.

How do you install Node Readiness Controller?

Grab from GitHub sigs.k8s.io/node-readiness-controller; deploy as a Deployment, author NRRs, test in dry-run. Docs in repo.

Is Node Readiness Controller ready for production?

Alpha1 now—fine for testing, risky for prod. Wait for beta, or run bootstrap-only on canaries. Word count: ~950.
