This will work only when running in the cluster.
For local testing, it's necessary to create Discourse API key and a keytab file for kinit.
Should I add the guide / links for creating a secret with keytab or it's out of the scope already? Or maybe just a mention that the API key and keytab will be necessary?

Noticed the PR now. The links/guide would be better.

Ok, will do, thanks!

@lenkaseg Did you have time to look at this?

Not yet, but I will make the time now :)

if this is a contributor guide, contributors will not have permission to push here ;) if its for local testing, maybe change to their own personal namespace on quay.io.

Ready for review!

Hm, I thought that we have a guide how to request a Kerberos keytab in Fedora Infra, but we don't have one. I found just this https://fasjson-client.readthedocs.io/en/latest/usage.html#configuring-an-application-for-kerberos-authentication

We have this:

https://pagure.io/fedora-infra/howtos/blob/main/f/create_keytab.md

Link changed to point to the pagure guide.
