Description

I'm wondering, is this actually a bug/limitation in OCP/Kube rather than the installer? Lets handle this in sanitize_inventory role While I agree it may be an issue in OpenShift, I have submitted the following PR to work around on our end: https://github.com/openshift/openshift-ansible/pull/5100 I don't believe sanitize_inventory is the most ideal place for this check as we can potentially populate other names as nodename. In QE's case, didn't set the openshift_hostname, the openshift_public_hostname set, when openshift_public_hostname greater than 63 installer still failed in "restart node" task, installer succeed when the openshift_public_hostname less than 64. Suggest to add one more check like this:
- fail:
msg: openshift_public_hostname must be 63 characters or less
when: openshift_public_hostname is defined and openshift_public_hostname | length > 63
By the way, when set openshift_public_hostname greater than 63 characters, the host has same internal and public hostname.
New pull request created: https://github.com/openshift/openshift-ansible/pull/5353 This pull request address the issue of openshift_public_hostname length as suggested by QE. merged Verified with version openshift-ansible-3.7.0-0.126.1.git.0.0bb5b0c.el7, installer failed when hostname has more than 63 characters.
