helm-operator

Experimental refactoring of the operator-framework's helm operator.

Why a fork?

The Helm operator type automates Helm chart operations by mapping the values of a Helm chart exactly to a CustomResourceDefinition and defining its watched resources in a watches.yaml configuration file.

For creating a Level II+ operator that reuses an already existing Helm chart, we need a hybrid between the Go and Helm operator types.

The hybrid approach allows adding customizations to the Helm operator, such as:

• value mapping based on cluster state, or
• executing code in specific events.

Quick start

• Add this module as a replace directive to your go.mod:

  go mod edit -replace=github.com/joelanford/helm-operator=github.com/stackrox/helm-operator@main
  

  For example:

  chart, err := loader.Load("path/to/chart")
  if err != nil {
     panic(err)
  }
  
  reconciler := reconciler.New(
     reconciler.WithChart(*chart),
     reconciler.WithGroupVersionKind(gvk),
  )
  
  if err := reconciler.SetupWithManager(mgr); err != nil {
     panic(fmt.Sprintf("unable to create reconciler: %s", err))
  }
