Description Mark Chappell 2020-05-11 15:14:04 UTC 
Description of problem:

During the initial configuration of our cluster tripleo-hosts-entries is currently mangling the VIP entries and dumping them all onto a single line:

"""
$ cat /etc/hosts

Additional info:

I suspect that joining using '' is the cause here:

From /usr/share/ansible/roles/tripleo-hosts-entries/tasks/main.yml :
{{ tripleo_hosts_entries_vip_hosts_entries | join('') }}
Comment 4 Cédric Jeanneret 2022-07-15 11:07:30 UTC 
Moving to 16.1 - we have the patch, there's a package, 16.0 is EOL...
Comment 8 David Rosenfeld 2022-11-03 18:26:21 UTC 
Manual inspection of /etc/hosts file on 16.1 deployments shows no mangled entries.
