Pro Tips

Use 'kubectl diff -f manifest.yaml' to preview changes before applying them to the cluster.

Use 'kubectl apply --dry-run=client -o yaml' to see what would be created without making changes.

Use Kustomize or Helm for managing environment-specific variations of manifests.

Common Mistakes

'kubectl apply' uses last-applied-configuration annotation. 'kubectl create' doesn't - mixing can cause issues.

Deleting the manifest file doesn't delete the resource. Use 'kubectl delete -f manifest.yaml'.
