Murmur docker from scratch

[Silmerias]

Hey guys since this #5516 I decided to move to docker and build from it. On the way of making it lightest possible I choosen to go the hard way and use FROM scratch. It globally worked well so far, however I have some issues probably related to some missing lib.

Murmur: v1.5.517
System: Debian 12
cmake args "-DVCPKG_TARGET_TRIPLET=x64-linux" "-Dclient=OFF" "-Dstatic=ON" "-DCMAKE_BUILD_TYPE=Release" ..

2023-12-10 00:21:05 <W>2023-12-09 23:21:05.202 QFile::at: Cannot set file position 0

2023-12-10 00:21:05 <C>2023-12-09 23:21:05.203 Failed to set final capabilities

Does anyone have an idea of what could be missing?

This seems like a permission issue to me.

Just to make sure though, you are aware that there exists an official Mumble docker image, right?

[Silmerias]

Yes I am aware of it, but I wanted to get in a more lightweight approach.
Btw official docker build do not work because of a submodule url issue, I can open an issue if you like :

[Krzmbrzl]

Hm that's odd. But yeah, please create an issue in the docker repo.

[Silmerias]

Before opening this issue I do more test because I don't have the same behavior out of WSL2 and Docker Desktop.

[Silmerias]

So I found out what was the issue. root user was used to start murmur because of entrypoint (my bad) so something goes wrong when murmur force and switch from root to the user referenced in the configuration in a container.
