OpenShift CRDs

In our EnvTest we need to define all the CRDs our operator depends on. So we need the CRD for github.com/openshift/api/route/v1.

Based on issue-1191 OpenShift does not publish CRDs for every resources it provides. For example route/v1 cannot be even generated with make update-codegen-crds in the openshift/api repository without the following trick.

  1. Create a stub route_crd.yaml file under route/v1 with the content:
apiVersion: apiextensions.k8s.io/v1
kind: CustomResourceDefinition
metadata:
  # name must be in the form: <plural>.<group>
  # <group> has to match the correspondig .spec field
  name: routes.route.openshift.io
spec:
  # group name to use for REST API: /apis/<group>/<version>
  group: route.openshift.io
  versions:
    - name: v1
      served: true
      storage: true
  scope: Namespaced
  subresources:
    # enable spec/status
    status: {}
  names:
    plural: routes
    singular: route
    kind: Route
  1. Add the following to the Makfile
$(call add-crd-gen,route,./route/v1,./route/v1,./route/v1)
  1. Run make update-codegen-crds. This will update the route_crd.yaml with the full CRD definition.

We store such generated CRDs in our repo under openshift_crds for now to avoid the need for regenerating them for every run.
