Pro Tips

Use 'helm template' to see rendered manifests without installing - great for debugging and review.

Keep values in a file: 'helm upgrade -f values.yaml release chart' for reproducible deployments.

Use 'helm diff' plugin to preview changes before running 'helm upgrade'.

Common Mistakes

Helm stores release history as Secrets. Large releases can consume significant etcd storage.

Review chart values and templates before installing third-party charts - they may have security implications.
