services:
  l4d:
    image:             rpufky/steam:stable
    restart:           unless-stopped
    container_name:    l4d2
    ports:
      - '27015:27015'
      - '27015:27015/udp'
    environment:
      - PUID=50520
      - PGID=50520
      - UPDATE_OS=1
      - UPDATE_STEAM=1
      - UPDATE_SERVER=1

      - TZ=America/Los_Angeles
    volumes:
      - /d/games/l4d2/data:/data
      - /etc/localtime:/etc/localtime:ro

Start the server to download game files and stop it.

dc up -d l4d2; dc logs -f
dc stop l4d2

When the message custom_server not found appears, all games files have been downloaded.

Create custom_server script.

Left 4 dead 2 requires server config files to be executed from the install directory, so always copy the current config on startup. Repeat for other files.

-pidfile must be used as the docker container cannot write to the default PID location. This will produce a cat: hlds.{PID}.pid: No such file or directory error.
