I think there is some sort of additional magic needed from a user with higher rights. I'm an admin in the math project (as is @Physikerwelt) and neither of us are able to setup anything in the "Domains" of the project using Horizon. There are simply no interface controls offered as shown in his screenshot.

I noticed that I can't create domains under deployment-prep, but math.wmflabs.org. should still be a domain that exists in this project... I went to try to create it but T134543: python-designateclient package version does not match between labtestweb2001 and silver got in the way.

There are two things happening here:

1. Creation of domains is currently an Ops-only activity. That's not a bug in our setup, but rather a fundamental issue with the OpenStack infrastructure; currently OpenStack forbids creation of a subdomain of a domain that is 'owned' by a different project, and it's not possible to have wmflabs.org be owned by more than one project. I've spoken to the Designate developers about this, and they confirm that there are multiple requests for a 'shared domain' feature and they're working on it.

2. You already have a proxy squatting on math.wmflabs.org, which makes it difficult (and/or impossible) to have a configurable domain at the same math.wmflabs.org name.

So, your options are...

a) suggest a different project-level domain name (other than math.wmflabs.org) and I'll create it, or...
b) I can tinker and see about getting the proxy and the domain to co-exist, which may cause some brief downtime for the current math.wmflabs.org host.

I wonder who is using http://math.wmflabs.org ?
Is it used for anything?

krenair@novaproxy-01:~$ host math.wmflabs.org
Host math.wmflabs.org not found: 3(NXDOMAIN)

dynamicproxy-api doesn't seem to have a record for it either

@Krenair, that's because he just deleted it, as per ongoing IRC discussion

The DNS problem is resolved.
On the other hand the IP does not respond anymore

$ ping beta.math.wmflabs.org
PING beta.math.wmflabs.org (208.80.155.185) 56(84) bytes of data.
^C
--- beta.math.wmflabs.org ping statistics ---

I'll try to fix that and close the ticket thereafter
