Unreal Tournament 2004 Server on Kubernetes

From time to time I play Unreal Tournament 2004 with my kids. Aging game, being older than either of them, is not an obstacle to having fun. However, the inability to host a networked game is. As Windows updates and firewall rules change, we end up figuring out who gets to host the game every few months. Well, no more!

To solve my issues, I decided to go with Laclede's LAN Unreal Tournament 2004 Dedicated Freeplay Server. This neat docker package has everything you need to host games on Linux infrastructure and, as often happens with docker, is trivial to run. If this is what you need, stop reading and start gaming.

But I wanted to go a small step further and set up this server to run on Kubernetes. Surprisingly, I didn't find any YAML to do the same, so I decided to prepare one myself.

PS: While the server image has been available for a while now and it seems that nobody minds, I would consider downloading an image copy, just in case.
