Declaring a Library Chart Type

Setting type to library and what that forbids.

Two Kinds of Chart

Every Helm chart declares a type in Chart.yaml. The default is application, but a second type exists purely for sharing template logic.

# Chart.yaml
apiVersion: v2
name: my-app
type: application

Enter the Library Chart

Set type: library and the chart stops being something you install. It becomes a toolbox of named templates for other charts to reuse.

# Chart.yaml
apiVersion: v2
name: common
version: 0.1.0
type: library
