Types

type AllocateRequest 

type AllocateRequest struct {
	DevicesIDs []string `protobuf:"bytes,1,rep,name=devicesIDs" json:"devicesIDs,omitempty"`
}
  • Allocate is expected to be called during pod creation since allocation failures for any container would result in pod startup failure.
  • Allocate allows kubelet to exposes additional artifacts in a pod's environment as directed by the plugin.
  • Allocate allows Device Plugin to run device specific operations on the Devices requested

type AllocateResponse 

type AllocateResponse struct {
	// List of environment variable to be set in the container to access one of more devices.
	Envs map[string]string `` /* 142-byte string literal not displayed */
	// Mounts for the container.
	Mounts []*Mount `protobuf:"bytes,2,rep,name=mounts" json:"mounts,omitempty"`
	// Devices for the container.
	Devices []*DeviceSpec `protobuf:"bytes,3,rep,name=devices" json:"devices,omitempty"`
	// Container annotations to pass to the container runtime
	Annotations map[string]string `` /* 156-byte string literal not displayed */
}

AllocateResponse includes the artifacts that needs to be injected into a container for accessing 'deviceIDs' that were mentioned as part of 'AllocateRequest'. Failure Handling: if Kubelet sends an allocation request for dev1 and dev2. Allocation on dev1 succeeds but allocation on dev2 fails. The Device plugin should send a ListAndWatch update and fail the Allocation request
