Overview

Headless Steam Service (Secondary)
This container relies on an existing working SteamHeadless running.

Features:
  • Run a second (or third or fourth) instance of steam on the Steam Headless desktop.
  • All the same features as Steam Headless accessed through an existing Steam Headless container
Notes: NETWORK TYPE:

Each instance of this container should be run on a "Custom: br0" network and should be configured with a unique "Fixed IP address".

RUNNING MULTIPLE INSTANCES:

Only one instance of Steam Headless can play a game at any time. If you start a second Remote Play link, it wil hijack the virtual monitor, and all input devices from the first one.

STORAGE PATHS:

Everything that you wish to save in this container should be stored in the home directory or a docker container mount that you have specified. All files that are store outside your home directory are not persistent and will be wiped if there is an update of the container or you change something in the template.

GAMES LIBRARY:

It is recommended that you mount your games library to /mnt/games/GameLibrary/SteamLibrary and configure Steam to add that path.

NVIDIA GPU:

To enable NVIDIA GPU support, ensure that you have installed the Nvidia-Driver plugin and add the "--runtime='nvidia'" parameter added to "Extra Parameters:"

AMD GPU:

To enable AMD GPU support, ensure that you have installed the Radeon-TOP plugin.

AMD OR INTEL HW ACCELERATED VIDEO ENCODING:

To enable support for VAAPI HW Accelerated Video Encoding, add the "--device='/dev/dri'" parameter added to "Extra Parameters:"
