Package manager for Kubernetes that helps you define, install, and upgrade complex Kubernetes applications using charts. Helm uses a packaging format called charts, which are collections of files that describe a related set of Kubernetes resources. A chart repository is an HTTP server that houses an index.yaml file and packaged chart archives.
