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