Comment 0 for bug 1912696

Brief Description
-----------------
Apply any application vault,portieris , the pods fails with "ImagePullBackOff" error since the
kubelet fails to resolve reference "registry.local:9001/docker.io/hashicorp/vault-k8s:0.4.0""

Severity
--------
Major

Steps to Reproduce
------------------
1)Upload vault and apply

system application-upload /usr/local/share/applications/helm/vault-20.06-14.tgz
system application-apply vault
2)Now monitor the pods status as it fails to download the image form local registry

[sysadmin@controller-0 ~(keystone_admin)]$ kubectl get pods -n vault
NAME READY STATUS RESTARTS AGE
sva-vault-0 0/1 ImagePullBackOff 0 10m
sva-vault-agent-injector-db6878c69-v7ghr 0/1 ImagePullBackOff 0 10m
sva-vault-manager-0 1/1 Running 0 10m
[sysadmin@controller-0 ~(keystone_admin)]$
3)pod events

  Normal BackOff 22s (x42 over 10m) kubelet, controller-0 Back-off pulling image "registry.local:9001/docker.io/vault:1.4.2"
4)Same issue for portieris images, i think it happens for any image from the local registry.

5)Also manual pull fails with "crictl"

[sysadmin@controller-0 ~(keystone_admin)]$ crictl pull registry.local:9001/docker.io/vault:1.4.2
FATA[0000] pulling image failed: rpc error: code = Unknown desc = failed to pull and unpack image "registry.local:9001/docker.io/vault:1.4.2": failed to resolve reference "registry.local:9001/docker.io/vault:1.4.2": pull access denied, repository does not exist or may require authorization: server message: insufficient_scope: authorization failed

but works with docker pull

[sysadmin@controller-0 ~(keystone_admin)]$ sudo docker pull registry.local:9001/docker.io/vault:1.4.2
