Instructions

Docker

The following are instructions for including this image as the base image for the Steam Dedicated Server that you can create based on this image.

Note: To make calling Steam CMD easier, the steamcmd.sh script has been added to the environment's PATH variable. If you need to access the files anyway, the location Steam was installed to is in the STEAMDIR Environment variable.

1. Create a Dockerfile with the following contents:

   FROM docker.io/renegademaster/steamcmd-minimal:<tag>
   
   # Add your own instructions here

2. You can then install a game server in one of several ways:

   • Install the game by adding additional Docker RUN instructions to the Dockerfile:

     FROM docker.io/renegademaster/steamcmd-minimal:<tag>
     
     # Download the Satisfactory Dedicated Server
     RUN steamcmd.sh +login anonymous +app_update 1690800 validate +quit

   • Alternatively, you can create a Steam CMD script and copy it into the /home/steam directory. This script can then be run when the container is started:

     FROM docker.io/renegademaster/steamcmd-minimal:<tag>
     
     # Copy the steamcmd script into the container
     COPY install.scmd /home/steam/install.scmd
     
     # Run the steamcmd script
     ENTRYPOINT steamcmd.sh +runscript install.scmd

   • Lastly, you can always create a Shell Script and copy it into the container to handle running more complex commands:

     FROM docker.io/renegademaster/steamcmd-minimal:<tag>
     
     # Copy the steamcmd script into the container
     COPY setup_script.sh /home/steam/setup_script.sh
     
     # Run the steamcmd script
     ENTRYPOINT ["/bin/bash", "/home/steam/setup_script.sh"]

Versions (root?)

Two versions of this image exist (alongside latest). The difference between the two are the access rights granted to the end image User. Images ending in *-root retain the root user and can install packages, or do other admin activities. Images without this suffix contain a steam user instead. This user cannot install packages, but is safer to use.
