macOS (ARM)

Note: SteamCMD Docker currently does not support ARM, but the ARK server can still run if downloaded from another platform in advance.

1. Download and Extract the Repository

git clone https://github.com/gordon0907/ark-server.git
cd ark-server

2. Set Executable Permissions & Build the Image

chmod +x *
docker build --tag ark-server:latest .

3. Run the Container

docker run --detach \
    --name SteamCMD \
    --env UID=501 \
    --env GID=20 \
    --env TZ=Asia/Hong_Kong \
    --publish 7777:7777/udp \
    --publish 7778:7778/udp \
    --publish 27015:27015/udp \
    --volume /Users/gordon/Downloads/SteamCMD:/home/steam/Steam \
    --volume "/Volumes/docker/SteamCMD/steamapps/common/ARK Survival Evolved Dedicated Server/ShooterGame/Saved":"/home/steam/Steam/steamapps/common/ARK Survival Evolved Dedicated Server/ShooterGame/Saved" \
    --env CPU_MHZ=3200 \
    --memory 10g \
    ark-server:latest

• Adjust UID and GID according to your system.
• Adjust CPU_MHZ based on your machine's CPU speed.
• It is recommended to keep the entire server directory on a local device instead of a network drive to prevent slow loading times.
• However, the save folder (container path: /home/steam/Steam/steamapps/common/ARK Survival Evolved Dedicated Server/ShooterGame/Saved) can be mounted separately to a network drive.

4. Modify start.sh

Comment out the server update command in start.sh, as SteamCMD is not supported on ARM.
