How to setup an MvM server with Docker

This is a simple guide on how to start an MvM server using Docker. This also works with Podman.

1. Generating an SRCDS Token

SRCDS_TOKEN is required if you want your server to be visible on the server browser. Follow the below steps to generate one:

Open the following link:
https://steamcommunity.com/dev/managegameservers
In the App ID field, type the following:
440
In the Memo field, type whatever you see fit. You may use the following:
MvM Server
Click on the "Create" button.
Copy the login token.

2. Docker

There are plenty of images that can be picked, which can be found here:
https://github.com/CM2Walki/TF2?tab=readme-ov-file#image-variants

For this guide, we will be going with the image that comes with SourceMod pre-installed.

Pull the latest image:

docker pull cm2network/tf2:sourcemod

Start and run the container, make sure to replace {YOURTOKEN} with the token you generated and {YOURPASSWORD} with a secure password:

docker run --net=host --name=my-mvm-server -e SRCDS_TOKEN="{YOURTOKEN}" -e SRCDS_RCONPW="{YOURPASSWORD}" -e SRCDS_PW="" -e SRCDS_STARTMAP="mvm_decoy" -e SRCDS_MAXPLAYERS=32 cm2network/tf2:sourcemod

Here's a breakdown for the command:

docker run: This command creates and starts a new container.
--net=host: The container shares the host's network stack, meaning it directly uses the host's IP address and ports.
--name=my-mvm-server: This names the container "my-mvm-server". You may change its name to whatever you see it.
-e SRCDS_TOKEN={YOURTOKEN}: This sets an environment variable SRCDS_TOKEN with a value of {YOURTOKEN}. This token is necessary to authenticate your server with Valve. Ensure to replace it with your own token.
-e SRCDS_RCONPW={YOURPASSWORD}: This sets an environment variable SRCDS_RCONPW with a value of {YOURPASSWORD}. This is the password for remote console access to the server. Ensure to replace it with a secure password.
-e SRCDS_PW="": This sets the environment variable SRCDS_PW to an empty string, meaning no password is required for players to join the server.
-e SRCDS_STARTMAP="mvm_decoy": This sets the initial map to "mvm_decoy" when the server starts. You may replaced it with any other MvM map if you want.
-e SRCDS_MAXPLAYERS=32: MvM bots take up player slots, so you need to set the max player to at least 32.
cm2network/tf2:sourcemod: This specifies the Docker image to use, which in this case is a TF2 server image with SourceMod pre-installed.

You can find other environment variables here:
https://github.com/CM2Walki/TF2?tab=readme-ov-file#environment-variables

After starting the container successfully, wait for the server to update. It might take some time.

Once the server update is complete, launch TF2, open the server browser, click on the "LAN" tab, if everything went well then you will be able to see and connect to your server. However, there are still things need to be done, so continue reading the guide.

3. Map rotation

To add stock MvM maps to your map cycle, run the following command:

docker exec -it my-mvm-server nano /home/steam/tf-dedicated/tf/cfg/mapcycle.txt

Add the following content to mapcycle.txt:

mvm_bigrock
mvm_coaltown
mvm_decoy
mvm_ghost_town
mvm_mannhattan
mvm_mannworks
mvm_rottenburg

4. Admin privileges

Since the server comes with SourceMod, it is a good idea to set yourself as an admin in order to access admin-only features.

4.1. Finding your Steam ID

Open the following website:
https://steamdb.info/calculator/
In the blank field, enter your Steam community profile URL, for example:
https://steamcommunity.com/id/kisats/
Click on the "Get disappointed in your life" button.
Copy the "Steam2 ID" value.

4.2. Becoming an Admin

To edit the admin list, run the following command:

docker exec -it my-mvm-server nano /home/steam/tf-dedicated/tf/addons/sourcemod/configs/admins_simple.ini

At the end of the file, add the following line. Ensure to replace YOUR_STEAM_ID_HERE with the Steam ID you copied previously:

"YOUR_STEAM_ID_HERE"  "99:z"

5. Changing server.cfg

The server.cfg file that comes with the image is targeted towards normal TF2 matches. It is important to change it so it fits MvM requirements. To do so, follow the steps below:

Remove the existing server.cfg file:

docker exec -it my-mvm-server rm /home/steam/tf-dedicated/tf/cfg/server.cfg

Create a new server.cfg file:

docker exec -it my-mvm-server nano /home/steam/tf-dedicated/tf/cfg/server.cfg

In the server.cfg file, insert the following content. Ensure to replace the values of hostname, rcon_password, sv_contact and sv_region:

// Change the following:
hostname my-mvm-server // This is the server name. It will be shown on the server browser.
rcon_password ChangeMe // Enter a secure password
sv_contact [email protected] // Type your email address
sv_region 255 // 0: US - East, 1: US - West, 2: South America, 3: Europe, 4: Asia, 5: Australia, 6: Middle East, 7: Africa, 255: World (Default)
