Dry Runs with --dry-run

Asking the server to validate without applying.

Ask the Server First

Where helm template renders locally, --dry-run goes one step further and asks the cluster to check the manifests without applying them. 🧪

helm install my-app ./mychart --dry-run

Render Plus Validate

A dry run renders your templates AND sends them to the API server for validation, then stops short of creating anything real.
