Types

type AllocateRequest 

type AllocateRequest struct {

}
  • 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

}

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
