Not clean but this shouldn't prevent re-install.

Please open a bug against certmonger.

I think IPA in docker is still rather experimental. Are you
re-installing within a docker image?

I don't know why the domain name would make a difference one way or another.

IPA just needs valid DNS names. It doesn't matter where they come from
or what they are.
There can be a conflict with realm names if you want to rely on DNS
discovery and there are conflicts (with AD for example).
