Killing Floor 1: Dockerized!

Important Notes

OSX 💻 Users

If, for any reason, you are encountering "Operation not permitted" issues while running, make sure you do the following:

1. In your Docker settings, disable/uncheck Use gRPC FUSE for file sharing and hit Restart to Apply changes
2. If the above doesn't solve your issue, go to your Machine Settings > Security & Privacy > Give Full Disk Usage to Docker.app (If this still doesn't work, give your terminal as well)

This should fix this issue 👍

Multi-Server 🌩 support

In case you want to run more than 1 server (e.g. several containers), do not forget to change the exposed ports in the docker run command to match the following:

KF_GAME_PORT=
KF_QUERY_PORT=
KF_WEBADMIN_PORT=

Also, keep in mind to update the folder you are using for the mounted volume on your local

-v (your server folder):/home/steam/servers/kf

And MOST IMPORTANT:

DO NOT Forget to change your steam ports to "Ranged" ports e.g.

20560:20569 (udp+tcp)

28852:28859 (udp+tcp)

7707:7710 (udp) # This change is for the 7708 port, in case you're doing only 2x servers

If you're running more than 2x servers, you need to keep incrementing your ports accordingly! +2 is optimal for all ports

You can run your containers using --net=host, or simply change the ports from the run command.

Docker Run Variables

When running a container for the first time, you will need to supply a steam login to install the server

• If you get password errors, just put your password in hyphons e.g 'Password_here'
• Make sure the code you provide (if you have 2FA enabled) is newly generated

STEAM_USER=
STEAM_PASSWORD=
STEAM_CODE=

Use these vars to tweak the server settings when a container starts

NOTE: Removing variables or not putting any values will automatically use the default values, as found HERE

# Map Name
KF_MAP=
# 1 Begginer, 2 Normal, 4 Hard, 5 Suicidal, 7 Hell On Earth
KF_DIFFICULTY=
# 0 --> 4 waves, 1 --> 7 waves, 2 --> 10 waves
KF_GAME_LENGTH=
# Server Name
KF_SERVER_NAME=
# Game Password, Do not provide the parameter if you want no password
KF_GAME_PASS=
# Admin Name
KF_ADMIN_NAME=
# WebAdmin Password
KF_ADMIN_PASS=
# Admin E-Mail
KF_ADMIN_EMAIL=
# Message Of The Day - Shows when someone joins the server
KF_MOTD=
# Redirect URL, if not set, defaults to Skillzserver (Includes almost all KF1 Mods)
KF_REDIRECT=
# Number of Max Spectators that can be in your server
KF_SPECTATORS=
# Change ZED skins based on the special events
# Select 1 of the following:
# ET_None -- Default
# ET_SummerSideshow -- for the summer ZEDs
# ET_HillbillyHorror -- for the Halloween ZEDs
# ET_TwistedChristmas -- for the Christmas ZEDs
KF_SPECIMEN_EVENT_TYPE=
# List of your mutators; seperated by commas and NO spaces -- It is recommended to use MutLoader to load your muts
KF_MUTATORS=
# DO. NOT. TOUCH! Port variables if you don't know what you're doing!
# Game Port
KF_GAME_PORT=
# Query Port
KF_QUERY_PORT=
# WebAdmin Port
KF_WEBADMIN_PORT=

Build Command

docker build -t kf1-docker .

Run Command

        -e KF_QUERY_PORT=7717 \
        -e KF_WEBADMIN_PORT=8075
        kf1-docker

or config taken from Env Var (see example env_file)

docker run -d --name kf1 \
        -p 0.0.0.0:7707:7707/udp \
        -p 0.0.0.0:7708:7708/udp \

        -e STEAM_CODE=(code) \
        --env-file=env_file \
        kf1-docker

Update the server

Sometimes, you need to update SteamLibs or in general the server if needed.

To do so, all you have to do is delete Core.u from your Volume/System/ and simply run the server as you usually do. If you use 2FA/Steam Guard, make sure to provide the proper code before running.

Useful docker commads

• Track installation/server setup after docker run command
  • docker logs --follow kf1-docker
• Stop & remove server container
  • docker stop $(docker ps -aq); docker rm -f Server_name_here
