# Runs a pre-built SS3D dedicated server (StandaloneLinux64, Server subtarget).
# The binary is not compiled inside this image - build it first (Unity Editor or
# the "Build Dedicated Server" CI job, see .github/workflows/main.yml) and pass
# its output directory as the build context, e.g.:
#   docker build -t ss3d-server -f Dockerfile build/StandaloneLinux64
