During IBM Z testing for AMQ-B, we encountered this failure due to the image no longer available.
Failed to pull image "quay.io/kcrane/cli-java": rpc error: code = Unknown desc = Error reading manifest latest in quay.io/kcrane/cli-java: unauthorized: access to the requested resource is not authorized
Kirk has indicated that he deleted the image so we are now in need a more guaranteededly accessible cli-java on s390x like docker.io/rhmessagingqe/.
