Docker setup

3 steps

Download

Free anonymous download, Steam app 2857200, about 2.9 GB. Force the Windows build.

docker volume create abiotic_files
docker run --rm -v abiotic_files:/data steamcmd/steamcmd:latest \
  +@sSteamCmdForcePlatformType windows +force_install_dir /data \
  +login anonymous +app_info_update 1 +app_update 2857200 validate +quit
docker run --rm -v abiotic_files:/data alpine chown -R 1000:1000 /data

Run

Developer example command under the Wine image from the Enshrouded page. Add -p 7777:7777/udp -p 27015:27015/udp to publish the ports.

docker run -d --name abiotic --init --memory 10g \
  -v abiotic_files:/abiotic -w /abiotic/AbioticFactor/Binaries/Win64 \
  wine_runtime wine ./AbioticFactorServer-Win64-Shipping.exe -log -newconsole \
  -useperfthreads -NoAsyncLoadingThread -MaxServerPlayers=6 -PORT=7777 -QueryPort=27015 \
  -ServerPassword=change-me -AdminPassword=change-me-too -SteamServerName="My server"

Ready line

World up 7.6 seconds after container start.

docker exec abiotic tail -F /abiotic/AbioticFactor/Saved/Logs/AbioticFactor.log | grep -m1 'Facility.Facility up for play'

Settings

9 settings

Launch options on the start command. Per-world settings: SandboxSettings.ini in the world's save folder.

Setting	What it does
`-MaxServerPlayers=6`	Player slots. Developer example: 6.
`-PORT=7777`	Game port, UDP.
`-QueryPort=27015`	Steam query port, UDP.
`-ServerPassword`	Join password.
`-AdminPassword`	Admin password.
`-SteamServerName`	Name in the server list.
`-WorldSaveName`	World to load or create. Default: Cascade.
`-useperfthreads -NoAsyncLoadingThread`	Developer example threading options.
`-log -newconsole`	Log to a console window and AbioticFactor/Saved/Logs.

Troubleshooting

3 problems

'No WorldSaveName param, using default: Cascade': Expected. Pass -WorldSaveName to pick or create a world.
'Engine is initialized' but players cannot join yet: That line is early. Wait for 'Bringing World /Game/Maps/Facility.Facility up for play'.
No connections from outside the network: Forward UDP 7777 and 27015. Friends can also join with the session short code in the log.
