Helm

aid: helm
name: Helm
description: >-
  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.

    description: >-
      The Helm Chart Repository API defines the HTTP endpoints used by Helm clients to discover and download charts from
      a repository server. This includes the index.yaml endpoint for chart discovery and chart package download
      endpoints. ChartMuseum extends this with a JSON-based management API for listing, uploading, and deleting charts.
