Using redhat containers

[cniackz]

Objective:

To use redhat containers for certification.

Reasoning:

https://access.redhat.com/support/cases/#/case/03522469
Once each container has been properly certified and published, then (and only then) can you certify your operator bundle.

How to test:

$ docker login https://registry.redhat.io
Username: <User>
Password: <Password>
Login Succeeded

image="registry.redhat.io/openshift4/ose-csi-external-provisioner"
docker pull "$image" | awk '/Digest/ { print $2}'

We also need to use registry.redhat.io/openshift4/ose-csi-node-driver-registrar instead of quay.io/minio/csi-node-driver-registrar:v2.6.3 in node-server daemonset.

btw, i cannot see the daemonset in minio-directpv-operator-rhmp.clusterserviceversion.yaml files. Though, i can see the daemonset in resources/base/.

We need the daemonset as well for DirectPV to work.

Also, we can keep just one latest version (currently, v4.0.5) until we get certified. We can remove the other versions - v4.0.3, v4.0.4.

We can take care of future versions after DirectPV gets published successfully.
