Kubernetes hardening without the theatre

Kubernetes does not become safe because the YAML is long. It becomes safer when teams understand boundaries, defaults and failure modes.

Start with boring controls

• Restrict privileges by default.
• Use namespaces for real isolation boundaries, not decoration.
• Keep workloads observable.
• Treat secrets as operational risk, not just configuration.
• Review ingress and egress paths.
