This repository can be used to build Left 4 Dead 1 + 2 as separate images.
By default, you'll want to allow both incoming TCP and UDP traffic on port 27015.
docker run -p 27015:27015/tcp -p 27015:27015/udp --name l4d2 left4devops/l4d2
Changes the port used inside the container, make sure your expose the new ports instead.
e.g docker run -e PORT=27016 -p 27016:27016/tcp -p 27016:27016/udp --name l4d2 left4devops/l4d2
This identifies your server in the server browser. By default, it is set to "Left4DevOps".
e.g. To change your hostname to BILLS HERE - docker run -e HOSTNAME="BILLS HERE"...
To help hint to Steam where your server is located, set the REGION environment variable as one of the following numeric regions:
| Location | REGION |
|---|---|
| East Coast USA | 0 |
| West Coast USA | 1 |
| South America | 2 |
| Europe | 3 |
| Asia | 4 |
| Australia | 5 |
| Middle East | 6 |
| Africa | 7 |
| World (Default) | 255 |
e.g. If your server was in Europe - docker run -e REGION=3...
Make your server easier to join by providing the ID of your Steam Group as shown on the admin page. You can also set STEAM_GROUP_EXCLUSIVE=true to reduce the chances of your server being used by other people.
If you would like to remote control the server without using SourceMod, set an RCON password using the RCON_PASSWORD environment variable. Once you are connected to the server, use the developer console to set rcon_password and then rcon.
- Make sure your RCON passsword is hard to guess or others will control your server!
- If using the default docker bridge networking, docker will not see the IP address of the client, and may ban the bridge IP.
You can skip the config created by environment vars by mounting in your own server.cfg
e.g. docker run -v server.cfg:/cfg/server.cfg...
If you wanted to play a custom campaign on your server, or include sourcemod, you can mount a directory with any custom content into the /home/louis/l4d2/left4dead2/addons/ directory.
e.g. If your working directory had a addons folder:
docker run -v $pwd/addons:/addons/...
There are a couple of ways you can achieve this:
- Start a lobby, then as host, open the developer console and type
mm_dedicated_force_servers [ip:port]. This will try to use your server when the game starts. - Using the developer console, you can connect directly to the server
connect [ip:port] - Add the server as a favourite using the server browser
openserverbrowserin game. This will make it appear as a steam group server in the menu. - Set the
STEAM_GROUPvariable and choose to start the game from a Steam Group server in your lobby.
Any commands sent to the docker will replace the default commands line options for ./srcds_run
e.g. docker run left4devops/l4d2 -port 27020 +map "c14m1_junkyard" +sv_lan 1 will execute ./srcds_run -port 27020 +map "c14m1_junkyard" +sv_lan 1.
