Creating your own charts

A chart is a collection of files that describe a related set of Kubernetes resources. A single chart might be used to deploy something simple, such as a Memcached pod, or something complex, such as a full web app stack with HTTP servers, databases, caches, queues, and so on.

Charts are created as files laid out in a particular directory tree. Then, they can be packaged into versioned archives to be deployed. The key file is Chart.yaml.

The Chart.yaml file

The Chart.yaml file is the main file of a Helm chart. It requires name and version fields:

  • name: The name of the chart (same as the directory name)
  • version: A SemVer 2 version

It may also contain various optional fields:

  • kubeVersion: A SemVer range of compatible Kubernetes versions
  • description: A single sentence describing this project
  • keywords: A list of keywords about this project
  • home: The URL of this project's home page
  • sources...
