How do you instal Rocky 9? Looks like basis image is not available from hetzner:

root@rescue ~ # ls -1 images/{CentOS,Rocky}*
images/CentOS-79-64-minimal.tar.gz
images/CentOS-79-64-minimal.tar.gz.sig
images/CentOS-80-stream-amd64-base.tar.gz
images/CentOS-80-stream-amd64-base.tar.gz.sig
images/CentOS-85-64-minimal.tar.gz
images/CentOS-85-64-minimal.tar.gz.sig
images/Rocky-85-amd64-base.tar.gz
images/Rocky-85-amd64-base.tar.gz.sig
root@rescue ~ #

I used this repository to create an OCP cluster on an already provisioned bare metal server running Rocky 9 (on Scaleway btw, not Hetzner).
Maybe this repository should be renamed libvirt-ocp4 and leave the 00-provision-hetzner.yml playbook optional ?

Good point, I have already thought about renaming it, but I am not clear about the impact.

They call it the "Danger Zone" but it's not that dangerous I think since when you rename a repo, the old name redirects on the new one.
For instance see https://github.com/debovema/DO288-applications which I renamed from https://github.com/debovema/DO288-apps (forked from https://github.com/RedHatTraining/DO288-apps). The

This repo (I mean https://github.com/RedHat-EMEA-SSA-Team/hetzner-ocp4) is very interesting as it bridges the gap between do-it-yourself, tedious, bare-metal installation and the "too limited" OpenShift Local (formerly CodeReady Containers).

The main drawback I find however is the prioritization of information for a newcomer.
For instance:

• do we really need Hetzner machines ? short answer seems to be no
• can we execute the playbooks remotely (from our laptop) ? it seems that yes but I had difficulties so I run it from the server directly

I'm experiencing the repo in-depth and doing some PR (add Gandi DNS Provider for example).

Then I can help to update documentation if you want.

@debovema Let's move the renaming discussion into an own Issue #232

@debovema Can you be so kind and update (rebase) to the latest devel tree version?
