The Image Controller for AppStudio helps set up container image repositories for AppStudio Components.

1. Install the project on your cluster by running make deploy.
2. Set up the Quay.io token that would be used by the controller to setup image repositories under the quay.io/redhat-user-workloads organization.

kind: Secret
apiVersion: v1
metadata:
  name: quaytoken
  namespace: image-controller-system
data:
  organization: redhat-user-workloads
  quaytoken: redacted
type: Opaque

To request the controller to setup an image repository, annotate the Component with image.redhat.com/generate: '{"visibility": "public"}' or image.redhat.com/generate: '{"visibility": "private"}' depending on desired repository visibility.

apiVersion: appstudio.redhat.com/v1alpha1
kind: Component
metadata:
  annotations:
    image.redhat.com/generate: '{"visibility": "public"}'
  name: billing
  namespace: image-controller-system
spec:
  application: city-transit
  componentName: billing

The image.redhat.com/generate annotation will be deleted after processing. The visibility status will be shown in visibility field of image.redhat.com/image annotation.

Also, it's possible to change the visibility of the repository after it's creation by setting the annotation again.

NOTE

Your quay.io organization plan should allow creation of private repositories. If your quay.io organization has free plan that does not allow setting repositories as private, then the error will be shown in message field of image.redhat.com/image annotation and the repository will not be created or will remain public.

If Component's auto-generated image repository should be deleted after component deletion, add image.redhat.com/delete-image-repo annotation to the Component.

The Image controller would create the necessary resources on Quay.io and write out the details of the same into the Component resource as an annotation, namely:

• The image repository URL.
• The image repository visibility.
• The name of the Kubernets Secret in which the robot account token was written out to.
