OMBKGS is a fork of Google's Open-Match which focusses around getting the complexity out of the original Open-Match solution, and hacking the repository down to its essentials for local use and extension by curious parties.
Open-Match looks cool, but its reliance on GCP and Kubernetes means that it's sort of incomprehensible to look into for anyone using a less onerous workflow, such as your common-or-garden game developer.
To check this project out, you'll need make, Go and Docker installed. Due to the reliance on make, it's probably going to be easier to run this using WSL2 or a true Linux install.
Afterwards, all you (should) need to do is run 'make build-images' followed by 'docker compose up' to get the images spun up. Finally, you can run the two programs in examples to watch a fake client generate Open Match tickets, and a fake director use the matches generated by Open-Match to get those fake tickets assigned to servers.
