Description of problem: Regex used for cluster name validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*'), while regex used for GCP is ([a-z]([-a-z0-9]{0,61}[a-z0-9])?). So cluster name for GCP platform must start with a lower case letter. Version-Release number of the following components: # ./openshift-install version ./openshift-install v4.3.0 built from commit 5e97f56e7885913c2c741fbe2d18be4ad2148ec3 release image registry.svc.ci.openshift.org/ocp/release@sha256:b68e7444baef46e79e64101bbb58bc02a30f4ccb647a1aaaf571239 How reproducible: 100% Steps to Reproduce: 1. Install a cluster by issuing the cli, and enter 123456 in the Cluster Name field ./openshift-install create cluster --dir=test --log-level=debug Platform: gcp Cluster Name: 123456 Actual results: Installation failed due to incorrect cluster name. Please find error message below. Error: Error creating Image: googleapi: Error 400: Invalid value for field 'resource.name': '123456-67rsh-rhcos-image'. Must be a match of regex '(?:[a-z](?:[-a-z0-9]{0,61}[a-z0-9])?)', invalid Expected results: Please modify the regex used by cluster name Additional info:
Verified with payload 4.4.0-0.nightly-2019-12-20-210709. Steps to verify as below: Set the cluster name to 123456 and create manifests ./openshift-install create manifests --dir '/home/jenkins/workspace/Launch Environment Flexy/workdir/install-dir' level=fatal msg="failed to fetch Master Machines: failed to load asset \"Install Config\": invalid \"install-config.yaml\" file: metadata.name: Invalid value: \"123456\": GCP requires cluster name to match regular expression (?:[a-z](?:[-a-z0-9]{0,61}[a-z0-9])?)"
