qdm12 / cod4-docker

Runs a Call of duty 4 Modern Warfare (cod4x) dedicated server in a Docker container.

COD4 Docker dedicated server

Call of duty 4 dedicated server in a 125MB Docker image.

Requirements

• COD4 Client game
• COD4 running on version 1.7 have to update to 1.8-20.1
• Original COD4 main and zone files required (from the client installation directory)

Features

• Cod4x server features
• Works with custom mods and maps (see the Mods section)
• Built-in HTTP file server for usermaps and mods (only works with .ff and .iwd files for security reasons)
• Runs without root (safer)
• Default cod4 configuration file server.cfg when not using mods, with exec server.cfg
• Works with the cod4x masterlist
• Cod4x server built from source
• Other Cod4x files server downloaded from cod4x.me
• Auto updates to the latest cod4x release
• Only 125MB
• See more Docker image tags: Docker Hub tags

Setup

We assume your call of duty 4 game is installed at /mycod4path

1. On your host, create the directories ./main, ./zone, ./mods and ./usermaps.

2. From your Call of Duty 4 installation directory:

   • Copy all the .iwd files from /mycod4path/main to ./main
   • Copy all the files from /mycod4path/zone to ./zone
   • (Optional) Copy the mods you want to use from /mycod4path/mods to ./mods
   • (Optional) Copy the maps you want to use from /mycod4path/usermaps to ./usermaps

3. As the container runs as user ID 1000 by default, fix the ownership and permissions:

   chown -R 1000 main mods usermaps zone
   chmod -R 700 main mods usermaps zone

   You can also run the container with --user="root" (unadvised!) if this doesn't work, or build the image with --build-arg UID=yourid.

4. Run the following command as root user on your host:

   docker run -d --name=cod4 -p 28960:28960/tcp -p 28960:28960/udp -p 8000:8000/tcp \
       -v /mycod4path/main:/home/user/cod4/main \
       -v /mycod4path/zone:/home/user/cod4/zone \
       -v /mycod4path/mods:/home/user/cod4/mods \
       -v /mycod4path/usermaps:/home/user/cod4/usermaps:ro \
       qmcgaw/cod4 +map mp_shipment

   The command line argument +map mp_shipment is optional and defaults to +set dedicated 2+set sv_cheats "1"+set sv_maxclients "64"+exec server.cfg+map_rotate

   You can also download and modify the docker-compose.yml file and run

   docker-compose up -d

HTTP server for custom mods and maps

By default, the container runs with an HTTP file server for mods and usermaps on port 8000.

• You can disable it with -e HTTP_SERVER=off
• You can change its published port with for example -p 9000:8000/tcp
• You can change its root URL with for example -e ROOT_URL=/cod4. This is useful if you use a reverse proxy.

1. Locate the relevant cod4 configuration file - for example main/server.cfg or mods/mymod/server.cfg

2. Modify/add the following lines & change youraddress to your IP or domain name:

   set sv_allowdownload "1"
   set sv_wwwDownload "1"
   set sv_wwwBaseURL "http://youraddress:8000" // supports http, https and ftp addresses
   set sv_wwwDlDisconnected "0"

3. Feel free to open an issue for help setting this up, such as port forwarding or reverse proxy setup help

Update your game

1. Make sure you updated your game to version 1.7 first (see this)
2. Download the COD4x client ZIP file
3. Using Winrar / 7Zip / Winzip, extract cod4x_client_20_1.zip to your COD4 game directory
4. Go in the extracted directory cod4-client-manualinstall_20.1 and double click on install.cmd
5. When launching the multiplayer game, you should see at the bottom right 20.1

Testing

1. Make sure you updated your COD4 Game to 1.8-19.0
2. Launch the COD4 multiplayer game
3. Click on Join Game
4. Click on Source at the top until it's set on Favourites
5. Click on New Favourite on the top right
6. Enter your host LAN IP Address (i.e. 192.168.1.26)
   • Add the port if you run it on something else than port UDP 28960 (i.e. 192.168.1.26:28961)
7. Click on Refresh and try to connect to the server in the list

Mods

Assuming:

• Your mod directory is ./mymod
• Your main mod configuration file is ./mymod/server.cfg

Set the command line option to +set dedicated 2+set sv_cheats "1"+set sv_maxclients "64"+set fs_game mods/mymod+exec server.cfg +map_rotate

Write protected args

The following parameters are write protected and can't be placed in the server configuration file, and must be in the command passed to the container:

• +set dedicated 2 - 2: open to internet, 1: LAN, 0: localhost
• +set sv_cheats "1" - 1 to allow cheats, 0 otherwise
• +set sv_maxclients "64" - number of maximum clients
• +exec server.cfg if using a configuration file
• +set fs_game mods/mymod if using a custom mod
• +set com_hunkMegs "512" don't use if not needed
• +set net_ip 127.0.0.1 don't use if not needed
• +set net_port 28961 don't use if not needed
• +map_rotate OR i.e. +map mp_shipment should be the last launch argument

By default, the Docker image uses this command.

TODOs

• UDP proxy for Windows
• Reload ability of cod4x
• Docker Healthcheck + HTTP healthcheck endpoint (i.e. for K8s)
• Add extra ping with udp proxy
• More env variables
  • Plugins
• Plugins
• Built-in mods?

cod4-docker's Issues

Sys_LoadLibrary error: steam_api.so

...
Unable to resolve hostname cod4update.cod4x.me:80
...
Unable to resolve hostname raw.githubusercontent.com:443
Error: Sys_LoadLibrary error: steam_api.so: cannot open shared object file: No such file or directory
Error: steam_api.so not found or it was not possible to load. Error is: no error occurred while loading shared library. Steam is not going to work.

I tried to add static libraries but still same error

It works running only: ./cod4x18_dedrun +map_rotate from this

game not loading. Maybe localization error?

Heho,
I'm trying to get this running, but encounter some errors. Can I use any localization of the game? I have the german game file. The main folder has some additional localized iwd files. In the zone folder is a subfolder "german". Inside are the ff files for the maps etc.
would be grateful, if you had some tips =)

Update to cod4x v21

Hi again

New server update for cod4x, v21, can you please update it :)

thanks

Support for Heroku

Can you please make Heroku Support

Masterlist

In order for the server to show up on the Activision Masterlist, you need to use host network mode for the container so that it can bind to the WAN/Internet IP address of your server. Additionally, you need to set +set net_ip 123.123.123.123 +set net_port 28961 as ARGS environment variable.

If using bridge network mode, the container will bind to the IP address of the Docker network and therefore won't show up on the Activision Masterlist, as the heartbeat will send a 'local' IP-address to the Masterserver (e.g. 172.16.X.X.).

Perhaps you can add this to the README :)

Some error in the docker logs

Hi!

I see this errors in the docker logs:
Failed to open serverstatus.xml
Couldn't write q3config_server.cfg
1Error: Waited 227 msec for missing asset "codescripts/delete.gsx"
^3Warning: WARNING: Couldn't open logfile: main/games_mp.log

The permissions are 777 on all direcetories.

Please help.
Thanks

Permissions zone and usermaps folder

Thank you for creating this Docker image!

In the README it says that the zone and usermaps folder should have chmod 400 permissions, but with those permissions the Docker container wouldn't start for me. Changing the permissions chmod 700, just like the main and mods folder, fixed the issue for me.

Logging doesnt work

Hi!

Could you repair the cod4 logging?

Thanks
Tamás

games_mp.log gets overwritten at every container (re)start

The games_mp.log gets overwritten/cleaned every time the container (re)starts. This is annoying, as I use the .log to parse statistics.

g_logsync is set to 3 in my server.conf, which should append the logfile every time the server is restarted:

1. • buffered means that the logs are not written to disk continuously, they are temporarily buffered in memory and written to disk later.
2. • continuous means that logs are written to disk when the event takes place. After a server restart a new log will be created. You will lose old logs after a restart/crash.
3. • append does the same as continuous but after a server restart the new loglines are appended to the previous log.

How can I prevent the logfile from being overwritten/cleaned every time the container (re)starts?

Thanks!

Server crashes on startup 19.0

My server crashes on startup with this log

Followed ur github instructions 1 by 1!

With the reason:

Server crashed: �BG_LoadWeaponDef: Could not find default weapon

Do you mabye now why? um not using any mods or something.

Also it sets this warning:

^3Warning: WARNING: Could not load weapon file 'weapons/mp/defaultweapon_mp'

Settings for port forwarding and server config

Hi, first of all, thanks for the awesome project!

Situation

I have a working server hosted on a linux box.
I startet the COD4 via steam and client updated correctly out of the box. AWESOME!

What I want

I want to share my server just with my friends... preferably not showing on the master server list.

Port forwarding

Using your docker-compose.yml opened port 8000 and 28960 (mapped then to 54321 and 54320 on my router)
Testing to connect via console

connect privateIP:54320

i got a Timeout.
According to the official Activision documentation, ports for PC have to be:

• TCP: 3074, 27014-27050
• UDP: 3074, 3478, 4379-4380, 27000-27031, 27036

Server settings

In the server.cfg there are a few settings i can change... like:

HTTP download

• set sv_wwwBaseURL "http://yourdomain" change the yourdomain with public ip or is best to have a CNAME on my DNS?

Secure Server

• set g_password "randomstrongpassword"
• set rcon_password "randomstrongpassword"
  Are those sufficient security settings, appart from good practice in linux hardening?

guess set sv_privatePassword "private slot passwords" is not needed if g_password is set.

Thanks a lot for your support!
Cheers

how to build with steam disabled?

I build the dockerfile locally for version cod4x v21.2, but now i have the steam enabled version.. as many of us play via wine, we do not want the steam integration, as many do not have steam installed inside wine

So how to build with steam requirement disabled?

IWD files in mod not getting picked up

Hi, thanks for reading.

I'm using GunGame v1.2 with some of my custom skins, music, etc...
This is the content of mods/TomyGunGame:
enterleave.log

gungame
gungame.cfg
gungame_mp.log
maps
mod.ff
q3config_server.cfg
qconsole.log
qconsole.log.old
server.cfg
z_gungame.iwd
z_gunskins.iwd
z_skins.iwd

It works fine if I host it on Windows, but with the Docker image, no content that is in the IWD files works - however the mod itself works fine.

I would appreciate any information that I might be missing :-)

I'm happy to provide any additional information regarding this issue as well.

Fix container to run on Windows

• File permission wise
• Network wise

Update to cod4 v1.9

With the new update, clients in v 1.9 can't connect:

rejected connect from version 19

https://cod4x.me/index.php?/forums/topic/5538-cod4-vers-19/&tab=comments#comment-22563

So the docker hub image needs to be updated:
https://cod4x.me/downloads/cod4x_server-linux_19.0.zip

Update to cod4 v2.0

Similar to #13 , this time this docker needs to be updated to version 2.0 or else we get the error rejected connect from version 20 in the server and users can't connect

cod4x also need to be updated
https://cod4x.me/downloads/cod4x_server-linux_20.1.zip

Hi there,i'd like to know,if i usd FRP proxy ,how can i public my server (show up on the Activision Masterlist).

Add Healthcheck

Perhaps you might be interested in the Healthcheck I added to my image. It checks if the COD4 server is still up/responding by sending 'getinfo' via RCON (using netcat) to the server every 30 seconds.
If for some reason the container would still run, but the healthcheck fails (e.g. the CoD4 server process is frozen), the Docker container will be marked as 'unhealthy'. Using a Docker image called 'autoheal' it will automatically restart the container.

Since our repos are too far apart, I cannot do a proper pull request, but feel free to copy the bits you need from my fork :)
