SteamCMD Docker

Docker image with SteamCMD utility, which allows you to automate builds of dedicated servers, games and other stuff

Using as base image

FROM 2chevskii/steamcmd:latest

# Invoke SteamCMD to install CS2 dedicated server
# into /cs2_ds directory
RUN ./steamcmd.sh +force_install_dir /cs2_ds +login anonymous +app_update 730 validate +quit

# Run your server
EXPOSE 27015/tcp
EXPOSE 27015/udp

WORKDIR /cs2_ds

ENTRYPOINT ["./cs2", "-dedicated", "+map", "de_dust2"]

Automating using SteamCMD scripts

On start, this image passes any file found under /docker-entrypoint.d to the SteamCMD using +runscript directive

Below you see an example of installing CS2 dedicated server using mounted script file

Notice the 'quit' instructions both at the and of the script
and passed as a docker run argument

This is important because by default this image starts in an interactive mode
