Pro Tips

Use separate namespaces for dev, staging, and prod to prevent accidental cross-environment operations.

Apply ResourceQuotas to namespaces to prevent any single team from consuming all cluster resources.

Use LimitRanges to set default resource requests/limits for pods in a namespace.

Common Mistakes

Deleting a namespace deletes ALL resources within it immediately. There's no undo.

Some resources are cluster-scoped (PVs, Nodes, Namespaces) and don't belong to any namespace.
