Helm

Helm packages a Kubernetes application's manifests, configuration, and dependencies into a single versioned "chart" that can be installed, upgraded, or rolled back with one command, instead of manually applying dozens of individual YAML files. A large public chart repository means most common software already has a ready-to-install Helm chart.

Helm is a fit for anyone deploying applications to Kubernetes who wants versioned, repeatable, parameterized installs rather than hand-managing raw manifests - it's the de facto standard packaging format that most other Kubernetes tools in this catalog, like Kong or Grafana, ship an official chart for.
