<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>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>
<p><br>
</p>
<p>Kind regards</p>
<p>Bernd</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>
