Like any other Kubernetes resource you describe a GameServer’s desired state via a specification written in YAML or JSON to the Kubernetes API. The Code Blind controller will then change the actual state to the desired state.
A Fleet is a set of warm GameServers that are available to be allocated from.
A GameServerAllocation is used to atomically allocate a GameServer out of a set of GameServers. This could be a single Fleet, multiple Fleets, or a self managed group of GameServers.
A FleetAutoscaler’s job is to automatically scale up and down a Fleet in response to demand.
