The implementation of kubernetes resource extension mechanism

At present, k8s mainly supports two kinds of resources: CPU and memory. In order to support the scheduling and allocation of other types of hardware resources that users need to allocate on demand, k8s implements the device plugin framework for resource integration of other types of hardware. For example, now machine learning uses GPU and other ...
