Civ5 Circus

Scripts and Dockerfiles to install and run a dedicated Civilization 5 server on a headless, GPU-less Linux machine.

How does it work

So Civ 5 Server is a Windows-only GUI application, that needs to render frames with OpenGL Direct3D (translated to OpenGL with wine)... This Docker setup creates a virtual X11 framebuffer for Civ to render to, provides a VNC server so you can remote in, installs Mesa such that the CPU can render frames (so no GPU needed), and libstrangle so that Civ only runs at 2 FPS, so rendering doesn't consume the CPU so much (though it still takes an enormous amount of CPU time).

How do you use it

1. First, Civilization 5 needs to be installed into the civ5 directory, as well as the CivilizationV_Server.exe file from the Civ 5 SDK. You can copy those files over yourself, or use provided script as ./install_civ5 <steam_username> <steam_password>.

2. Then you build the game server container with ./build_server

3. Fianlly you can launch the game server container with ./run_the_circus.

4. After the container starts running, you should be able to remote in with VNC. The ./run_the_circus script is set up to only allow connections from localhost, so you'll want to open up an SSH tunnel if remoting in from a different machine first:

   ssh -f user@server -NL 10411:127.0.0.1:10411 
   

   Then, you should be able to point your VNC client at localhost:10411 and see Civ 5 running. Steam will also be running - it needs to stay running the background for Civ to not crash, though you don't need to log in to it.

5. Setup the game through the VNC connection, and hope that it works and people can connect.

Ports you might need to open/let through a firewall

The 27016 UDP is the only port you need to allow incoming traffic through.
