YUZU_ROOMDESC		(Optional) Description of the room.

YUZU_PASSWORD		(Optional) Room password (NOT recommended, see the section below).
YUZU_ISPUBLIC	0	(Optional) Make the room public. Valid User Token and Web API URL are required.
YUZU_TOKEN		(Optional) The user token to use for the room. Required to make the room public.
YUZU_WEBAPIURL		(Optional) URL to the custom web API. Required to make the room public.

Password protection

The server can be protected with a (clear, unencrypted) password by:

— Bind mount a text file containing the password into the container.
The mountpoint path has to be /run/secrets/yuzuroom.
This is the recommended method. See the second example in the section below.

— Using the YUZU_PASSWORD environment variable when creating the container.
This method is NOT recommended for production since all environment variables are visible via docker inspect to any user that can use the docker command.

Usage

Example 1:
Run a public server for SSB. Ultimate on port 51267 with a maximum of 16 members:
— You need a valid User Token to make the server reachable via the public room browser.

docker run -d \
  --name yuzu-room \
  -p 51267:51267/tcp \
  -p 51267:51267/udp \
  -e YUZU_PORT=51267 \
  -e YUZU_ROOMNAME="USA East - SSB. Ultimate" \
  -e YUZU_ROOMDESC="Fight On!" \
  -e YUZU_PREFGAME="SSB. Ultimate" \
  -e YUZU_PREFGAMEID="01006A800016E000" \
  -e YUZU_MAXMEMBERS=16 \
  -e YUZU_ISPUBLIC=1 \
  -e YUZU_TOKEN="<USER_TOKEN>" \
  -e YUZU_WEBAPIURL="<CUSTOM_API_URL>" \
  -i k4rian/yuzu-room

Example 2:
Run a private password-protected server using default configuration:
— In this example, the password is stored in the secret.txt file located in the current working directory.

docker run -d \
  --name yuzu-room \
  -p 24872:24872/tcp \
  -p 24872:24872/udp \
  -v "$(pwd)"/secret.txt:/run/secrets/yuzuroom:ro \
  -i k4rian/yuzu-room

Example 3:
Run a password-protected testing server on port 5555:

docker run -d \
  --name yuzu-room-test \
  -p 5555:5555/tcp \
  -p 5555:5555/udp \
  -e YUZU_PORT=5555 \
  -e YUZU_PASSWORD="testing" \
  -i k4rian/yuzu-room

Using Compose

See compose/README.md

Manual build

Requirements:
— Docker >= 18.09.0
— Git (optional)

Like any Docker image the building process is pretty straightforward:

• Clone (or download) the GitHub repository to an empty folder on your local machine:

git clone https://github.com/K4rian/docker-yuzu-room.git .

• Then run the following command inside the newly created folder:

docker build --no-cache -t k4rian/yuzu-room .

The building process can take up to 10 minutes depending on your hardware specs.
A quad-core CPU with at least 1 GB of RAM and 3 GB of disk space is recommended for the compilation.
