Notes

  • •Always specify -n namespace to avoid operating on the wrong namespace.
  • •Use --dry-run=client -o yaml to preview changes before applying.
  • •Confirm before running destructive operations (delete, scale to 0, drain).
  • •For multi-cluster setups, use kubectl config use-context to switch contexts.
