A noob here trying to start a Arma 3 Server

Greetings, a noob here, i want to use a docker container as my Arma 3 Server

structure:

D:\arma3\ (contains)

start .sh contains:

#!/bin/bash
cd /arma3/server
./arma3server -config=server.cfg -port=2302 -name=sc



The Dockerfile contains:
#!/bin/bash
cd /arma3/server
./arma3server -config=server.cfg -port=2302 -name=sc

D:\arma3\server (contains)

When i start the container, following happens:

steamcmd.sh[1]: Starting  /root/.local/share/Steam/steamcmd/linux32/steamcmd

Redirecting stderr to '/root/.local/share/Steam/logs/stderr.txt'

Logging directory: '/root/.local/share/Steam/logs'

[  0%] Checking for available updates...

UpdateUI: skip show logo

Steam Console Client (c) Valve Corporation - version 1782532820

-- type 'quit' to exit --

Loading Steam API...IPC function call IClientUtils::GetSteamRealm took too long: 44 msec

OK

and then nothing happens, the arma server should start?

Im a noob with AI trying to play arma with friends.
thank you in advance i will try to give as much info as i can.

You shared the shell script again instead of the Dockerfile content, but I guess you would need someone who understands Arma server or Steam and how it should be started, not just someone working with containers. For example there is the same error message here (using only google, not AI):

The exact cause of the error could be different. Maybe you are using a wrong parameter.
