| I wrote a Jenkins pipeline to copy remote images to the OpenShift repository with skopeo. Unfortunately I can't make the pipeline run due to a "unable to retrieve auth token: 401 unauthorized" error which quits the pipeline. However using the same command in the terminal works fine. So my guess is that Jenkins interpretes an error "{{Ping https://docker-registry.default.svc:5000/v2/ status 401" }}to fail and stop the whole command, while when I run the command in the terminal it shows the same message but continues and finish successfully. My pipeline step:
sh """
skopeo --tls-verify=false --debug inspect -- creds='${dest_user}:${dest_pw}' docker://${registry}/${namespace}/image:${build}
"""
The Jenkins pipeline output from the skopeo inspect call:
time="2020-01-24T21:22:39Z" level=debug msg="Using registries.d directory /etc/containers/registries.d for sigstore configuration"
time="2020-01-24T21:22:39Z" level=debug msg=" No signature storage configuration found for docker-registry.default.svc:5000/path/image:latest"
time="2020-01-24T21:22:39Z" level=debug msg="GET https://docker-registry.default.svc:5000/v2/"
time="2020-01-24T21:22:39Z" level=debug msg="Ping https://docker-registry.default.svc:5000/v2/ err "
time="2020-01-24T21:22:39Z" level=debug msg="Ping https://docker-registry.default.svc:5000/v2/ status 401"
time="2020-01-24T21:22:39Z" level=fatal msg="unable to retrieve auth token: 401 unauthorized"
Then quits! While in the terminal I see the same ping with "status 401", but it continues:
skopeo --tls-verify=false --debug inspect --creds=":" docker://docker-registry.default.svc:5000/path/image:latest
DEBU[0000] Using registries.d directory /etc/containers/registries.d for sigstore configuration

......
So something in Jenkins must force the command to stop. How can I avoid this and make Jenkins handle the command like it would be run from the Terminal. |
