undercloud install error "invalid IPNetwork undercloud.rdocloud" when undercloud_public_host set to hostname

[James Slagle]

In my undercloud.conf, I have undercloud_public_host set to a hostname, as that was always supported with instack-undercloud so that you could bind public SSL services to a hostname during undercloud install, and generate the cert with a hostname CN subject.

Now however with tripleoclient, that seems to fail:

I want to say that https://bugs.launchpad.net/tripleo/+bug/1799724 fixes this?

[Trevor Vardeman (tvardeman)]

I did an undercloud deployment earlier with the following options:
local_ip=192.168.0.21/24
undercloud_public_host=undercloud.rdocloud

My installation made it past the network setup. Full disclosure, it failed on ansible setup, but that isn't related. I think this bug can be closed.
