$ helm convert --help

The conversion is currently quite basic and has the following features:

  • get image tags and store them in kustomization.yaml
  • get common labels and store them in kustomization.yaml
  • get resources and store them in kustomization.yaml
  • remove helm specific labels from manifests
  • remove helm specific annotations from manifests
  • get namespace and store it in kustomization.yaml
  • create secretGenerator based on secret resources (type Opaque and TLS)
  • create secretGenerator based on secret type TLS
  • create configGenerator from multiline files
