<p>You can distribute ownership over more accounts that are not restricted to HD or BW. So (sadly), I'd expect that the GitLab instance and its Dune group would simply not react to your retirement a lot. If it helps, I can formally share ownership, I have ten
more years.</p>

<p>Hi Bernd,</p>
<p>this sounds interesting, I did not know that. We talked for years with URZ and it did not materialize and that was actually the reason to move our gitlab to Dresden. If it works now, it is fine. </p>
<p>However, what happens of there is no Dune related group in Heidelberg anymore (... I have less than 5 years to go...)?</p>
<p>Best,</p>
<p>Peter</p>

<p>Dear Dune developers,</p>
<p><br>
</p>
<p>Maybe you're already considering this option, I'd anyway would like to point you to <a href="https://bwgit.de" class="OWAAutoLink moz-txt-link-freetext" moz-do-not-send="true">https://bwgit.de</a>. This aims to be a permanent service, I think staffed with
1-2 full-time equivalents, hosted in Heidelberg and administrated jointly by Heidelberg and KIT. They run a GitLab Enterprise instance.</p>
<p><br>
</p>
<p>The groups on the top level <a href="https://bwgit.de/explore/groups/active" class="OWAAutoLink moz-txt-link-freetext" moz-do-not-send="true">
https://bwgit.de/explore/groups/active</a> are structured by location, but there would also be a cross-cutting group "Hubs".</p>
<p><br>
</p>
<p>If someone from a bwGit-participating institution (like Heidelberg) becomes owner of a Dune group, they can invite anybody that can authenticate via Helmholtz ID, including GitHub, Google and ORCID.</p>
<p><br>
</p>
<p>For the reasons mentioned by Christoph, we aim to move Dumux to there from our local GitLab instance. The first contact with the Heidelberg admin was very positive.</p>
<p><br>
</p>
<p>In my understanding, they offer everything that would be required. So far, I only have small-scale experience with two teaching projects with a little bit of CI including pages, <a href="https://bwgit.de/st/iws/lh2-lehre" class="OWAAutoLink moz-txt-link-freetext" moz-do-not-send="true">https://bwgit.de/st/iws/lh2-lehre</a>.
Up to now, everything worked.</p>
<p><br>
</p>
<p>You could just contact <span><a class="moz-txt-link-abbreviated" href="mailto:gitlab-support@urz.uni-heidelberg.de">gitlab-support@urz.uni-heidelberg.de</a></span> to find out if moving there appears to be promising.</p>

<div dir="ltr">I think Dune as a project does not have the manpower to take care of their own instance of GitLab. Updates, bots, CI issues are all time killers that are not improving our code. On the other hand, what do we gain from hosting it ourselves?</div>
<div dir="ltr">I would move to GitLab. Either we pay or we use the open source plan from GitLab [1]. I use it for Alberta-FEM and the yearly process of renewal is okay so far. This would give us access to macOS runners and we can still have CI resources where
they are today.</div>
<div dir="ltr">Other options like Codeberg or GitHub are possible. I don’t see any advantages, but I might be missing good arguments.</div>
