Overview of building a DRA resource driver for Kubernetes
A DRA resource driver consists of a centralized controller and a node-local plugin
Communication between the two components can be done through a single all-purpose CRD
The controller makes allocation decisions and the plugin advertises available resources
The driver needs to define a name, communication strategy, resource types, class parameters, and API access
Helper libraries are available to make implementation easier
