KReference.Group field

Flag name: kreference-group

Stage: Alpha, disabled by default

Tracking issue: #5086

Persona: Developer

When using the KReference type to refer to another Knative resource, you can just specify the API group of the resource, instead of the full APIVersion.

For example, in order to refer to an InMemoryChannel, instead of the following spec:

apiVersion: messaging.knative.dev/v1
kind: InMemoryChannel
name: my-channel

You can use the following:

group: messaging.knative.dev
kind: InMemoryChannel
name: my-channel

With this feature you can allow Knative to resolve the full APIVersion and further upgrades, deprecations and removals of the referred CRD without affecting existing resources.

Note

At the moment this feature is implemented only for Subscription.Spec.Subscriber.Ref and Subscription.Spec.Channel.
