nextdemo

These are the YAML files used for the Open Match and OMAG demos in the Cloud Next 2019 session Large-Scale Multiplayer Gaming on Kubernetes.

Usage

These files are provided as-is, for reference only. They do not represent best practices or how you should set up an Open Match cluster or anything like that. They are just the files used in the demo, nothing more, nothing less. Don't use these if you don't know what they do, and I accept no responsibility for the effects of them if you elect to use them.

Contributing

This is an archived repository, and will not accept PRs.

Commands

Here is a copy-paste of the commands cheat-sheet referenced while on stage. This is not a script or a list of things to run in order to get the demo to execute, it's just a list of commands that are useful when using these demo materials in roughly the order they are useful.
