server_linux.sh can't find executable file.

Hello. I'm trying to create a Dockerfile to run a xonotic in a container. So far, I've written this:

Code:

FROM alpine:latest

EXPOSE 26000

RUN mkdir ~/.xonotic
RUN mkdir ~/xonotic

COPY "./server.cfg" "~/.xonotic/data"

CMD [ "/home/root/xonotic/server_linux.sh" ]

And I run it with this command:

Code:

docker run -p 26000:26000 -v C:/Users/my_user/Downloads/Xonotic:/home/root/xonotic xonotic

But I get this error:

Code:

/home/root/xonotic/server_linux.sh: exec: line 24: ./xonotic-linux64-dedicated: not found

The file is the folder. I verify it by changing the CMD instruction to CMD [ "ls", "-l", "/home/root/xonotic" ]
Then running the container (with the same command) results in:

Code:

Any idea why could this be happening?

I fixed it. Apparently it was a problem with alpine because it works with ubuntu:latest

I have another problem. When I run the server it prints

Code:

You have started a dedicated server but have not created
any server.cfg in your config directory.

But the server.cfg is in /home/root/.xonotic/data/, I checked with an ls

The home folder for root is normally "/root/". But even in docker, it's a good idea to run software with an unprivileged user.

That fixed it, thanks. I have this error now:

Code:

execing autoexec/empty.cfg
execing autoexec.cfg
Quake Error: session lock /home/xonotic/.xonotic/lock could not be acquired. Please run with -sessionid and an unique session name.

This is my dockerfile

Code:

FROM debian:bookworm

EXPOSE 26000

RUN useradd xonotic

USER xonotic

COPY "./server.cfg" "/home/xonotic/.xonotic/data/"

CMD [ "/home/xonotic/xonotic/server_linux.sh" ]

I tried adding -sessionid idk to the server_linux.sh call but didn't work
Thanks in advanced
