$ openshift-install version
4.8.0 and up 


#Please specify the platform type: aws, libvirt, openstack or baremetal etc.

Please specify:
IPI (automated install with `openshift-install`. If you don't know, then it's IPI)

What happened?

When creating a cluster / manifests with a vcenter hostname that begins with a number, validation fails with the following:

DEBUG       Loading Platform...
FATAL failed to fetch Master Machines: failed to load asset "Install Config": invalid "install-config.yaml" file: platform.vsphere.vCenter: Invalid value: "1your.vcenter.server": must be the domain name or IP address of the vCenter

What did you expect to happen?
cluster / manifests to be created succesfully

How to reproduce it (as minimally and precisely as possible)? Use the sample yaml from the documentation with a vcenter name that begins with a number

/usr/local/bin/openshift-install-4.8.17 create manifests --dir ~/ocp4/vtest --log-level=debug

Anything else we need to know?
This seems to be discussed here: https://github.com/openshift/installer/issues/5126

Setting the severity to high as this affects all users trying to install to a vCenter that starts with a number.

Comment 4 jima 2021-12-09 02:29:09 UTC
create install-config.yaml file and set platform.vsphere.vCenter value as "1aaa.bbb.ccc.vmwarevmc.com".

verified against 4.9.0-0.nightly-2021-12-08-041936 which includes the fix.
issue is fixed, move bug to VERIFIED.

since the vcenter domain name I used is flake one, so installer failed with expected error.
