Running/installing UCS 5.x image from Docker Hub in a docker container fails

want to test UCS in a docker container and downloaded the image from the Docker Hub here, I think this is the newest image ?

Installing the container exactly as described the container was created by docker and started.
But then the conatiner war restarted every seconds.

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4ab39bc838f1 univention/univention-corporate-server “/bin/systemd” 34 minutes ago Restarting (255) 17 seconds ago node.ucs-6665

Without the option “–restart unless-stopped” the container exit immediately without any log or additional infos.

I tested it on a Mac with macOS Sonoma 14.1.2 (with the docker option “–platform linux/amd64”): Docker version 25.0.2, build 29cf629
and
on an unraid-server (x86_64 ) with the docker app (with and without the “–platform” option): Docker version 20.10.24, build 297e128
→ no luck.

Was anyone been able to install a fully running UCS image in a docker container ?

Any help is appreciated …

Update:

checked the installation procedure with another Univention (old) image on Docker Hub (here) .

No problem with the installation of the (version 4.0) image under Docker on an iMac as well as on the unraid server (linux, x86_64).

It seems that the Univention image file itself is faulty which is why the tips from Github (here) don’t help
