Server won't start properly

[lennard0711]

After starting the container with docker-compose up the Container starts to build and tries to start the server but fails.

Logs:

gmod-server    | Auto detecting CPU
gmod-server    | Using default binary: ./srcds_linux
gmod-server    | Server will auto-restart if there is a crash.
gmod-server    | Setting breakpad minidump AppID = 4000
gmod-server    | [S_API] SteamAPI_Init(): Loaded 'steamclient.so' OK.
gmod-server    | CAppInfoCacheReadFromDiskThread took 1 milliseconds to initialize
gmod-server    | CApplicationManagerPopulateThread took 1 milliseconds to initialize (will have waited on CAppInfoCacheReadFromDiskThread)
gmod-server    | [S_API FAIL] Tried to access Steam interface SteamUser020 before SteamAPI_Init succeeded.

But if go into the container now with docker exec -it gmod-server bash or docker exec -it gmod-server shand execute the entrypoint script the server starts without problems.
