Docker-compose

Use the docker-compose.yml file inside a folder. It will automatically create 4 folders in which the missions, configs, mods and servermods can be loaded.

Copy the .env.example file to .env, containing at least STEAMUSER and STEAMPASSWORD.

Use docker-compose start to start the server.

Use docker-compose logs to see server logs.

Use docker-compose down to shutdown the server.

The network_mode: host can be changed to explicit ports if needed.

Use docker-compose up -d to start the server, detached.

See Docker-compose for an installation guide.

Profiles are saved in /arma3/configs/profiles

Loading mods

1. Place the mods inside /mods or /servermods.
2. Be sure that the mod folder is all lowercase and does not show up with quotation marks around it when listing the directory eg '@ACE(v2)'
3. Run the following command from the mods and/or servermods directory to confirm that all the files are lowercase. find . -depth -exec rename 's/(.*)\/([^\/]*)/$1\/\L$2/' {} \; If this is NOT the case, the mods will prevent the server from booting.
4. Make sure that each mod contains a lowercase /addons folder. This folder also needs to be lowercase in order for the server to load the required PBO files inside.
5. Start the server.
