hosts file can't handle hostnames with domain

[dennisTGC]

What happened?

If i create a hosts file with nodes like
servername01.domain
servername02.domain

The playbook cluster.yml fails with creation of the first control plane node. If i create a host file with just the IP's, the playbook runs fine.

It looks like the SAN certs have an issue with hostnames while creating the first control_plane node.

What did you expect to happen?

that the playbook could handle hostnames with domainname like server01.local1

How can we reproduce it (as minimally and precisely as possible)?

create a hosts file with server01.local1 (use the /etc/hosts file for resolving) and run the playbook with default k8s-cluster.yaml and all.yml

Sorry, I had another conflicting parameter which broke the install. Although I thought I had a default k8s-cluster.yml and all.yml, I had enabled kube-vip in addons.yml, which seems to be broken #11338

So I will close this issue, as it is simply not true. ;-)
