Hi,
I have a proposal.
The new k8s haproxy is in front of the api-server and the ingress [0].
In toolsbeta we have been using the following:
toolsbeta-k8s-master.toolsbeta.wmflabs.org:6443 (api-server)
toolsbeta-k8s-master.toolsbeta.wmflabs.org:30000 (ingress)
This haproxy knows which k8s nodes/controllers are UP and proxy the queries for
them. Right now, this FQDN is not using a floating IP, is a simple A record
pointing to the haproxy VM. This record is in the 'toolsbeta' CloudVPS project.
I've been wondering which FQDN would be nice to have in the final deployment.
We have 'toolforge.org', but `whatever.toolforge.org` is intended to be a tool
webservice, so I've been re-reading our DNS domains plans [1] and my proposal is
to introduce a new FQDN like this:
k8s.toolforge.wmcloud.org
Then we can use it this way:
k8s.toolforge.wmcloud.org:6443 (api-server)
k8s.toolforge.wmcloud.org:30000 (ingress)
This is because 'wmcloud.org' is set to become the replacement for
'wmflabs.org'
which is what we are currently using for
'toolsbeta-k8s-master.toolsbeta.wmflabs.org'.
We could also create
k8s.toolsbeta.wmcloud.org (or whatever) in case we want to
retain the toolsbeta setup online.
I hope this proposal is not increasing our naming confusion and complexity.
Ideally we would use something like `k8s.toolforge.org` but that seems even more
confusing in the long term.
I already requested the
wmcloud.org domains to be pointed to designate [2].
Let me know!

Using *.tools.wmcloud.org (or *.tools.eqiad1.wmcloud.org?) for these
names might be a better match for the future plans for
wmcloud.org.
'tools' is the name of the Cloud VPS project for Toolforge. It is not
likely that we will grant a new Cloud VPS project named 'toolforge'
due to the very real confusion it would cause to us and others, but
breaking from the project name == subdomain convention seems like it
would also be confusing.
Another option would be *.tools.wikimedia.cloud (or
*.tools.eqiad1.wikimedia.cloud?) which I believe is the naming
convention we have agreed on for replacing *.wmflabs internal DNS.
