Pulling OpenShift image causes authentication required error

[imicer]

I follow the document to check if register image can be pulled when running 7-1 section, but the error message is output as below:

[root@support data]# podman pull ${REG_DOMAIN}/${REPO_NAME}:4.3.29-jenkins
Trying to pull registry.example.internal:5000/ocp4/openshift4:4.3.29-jenkins...
  unauthorized: authentication required
Error: error pulling image "registry.example.internal:5000/ocp4/openshift4:4.3.29-jenkins": unable to pull registry.example.internal:5000/ocp4/openshift4:4.3.29-jenkins: unable to pull image: Error initializing source docker://registry.example.internal:5000/ocp4/openshift4:4.3.29-jenkins: Error reading manifest 4.3.29-jenkins in registry.example.internal:5000/ocp4/openshift4: unauthorized: authentication required

But after I tried to login register server manually, I can pull the image from register.

[root@support data]# podman login -u openshift -p redhat ${REG_DOMAIN}/${REPO_NAME}
Login Succeeded!

Can you help take a look?
I suspect this error is related to co/authentication, I am still blocked by this issue now!
Thanks.

You could omit that line and move forward.
