we have a RHCOS+openshift4.4 container platform using vSphere/VmWare .
Issue: crictl cannot pull images from internal dockerhub.internal.com repository. It can pull images from hub.docker.com
However, podman can pull from dockerhub.internal.com and hub.docker.com
but, both crictl and podman can pull images from cloud repo hub.docker.com. ie. crictl pull mango:latest and podman pull mongo:latest work fine.
following command to pull image from internal repo/registry fails
crictl pull dockerhub.internal.com/mongo:2.2 . . . pulling image failed: rpc error: code = unknown desc = error pinging docker registry
has anyone faced this situation.
