Types ¶
type ContainerInfo ¶
type ContainerInfo struct { // The Annotations for the container Annotations []kubecontainer.Annotation }
ContainerInfo contains information required by the runtime to consume prepared resources.
type Manager ¶
type Manager interface { // PrepareResources prepares resources for a pod. // It communicates with the DRA resource plugin to prepare resources. PrepareResources(pod *v1.Pod) error // UnprepareResources calls NodeUnprepareResource GRPC from DRA plugin to unprepare pod resources UnprepareResources(pod *v1.Pod) error // GetResources gets a ContainerInfo object from the claimInfo cache. // This information is used by the caller to update a container config. GetResources(pod *v1.Pod, container *v1.Container) (*ContainerInfo, error) // PodMightNeedToUnprepareResources returns true if the pod with the given UID // might need to unprepare resources. PodMightNeedToUnprepareResources(UID types.UID) bool }
Manager manages all the DRA resource plugins running on a node.
type ManagerImpl ¶
type ManagerImpl struct {
// contains filtered or unexported fields
}
ManagerImpl is the structure in charge of managing DRA resource Plugins.
func NewManagerImpl ¶
func NewManagerImpl(kubeClient clientset.Interface) (*ManagerImpl, error)
NewManagerImpl creates a new manager.
func (*ManagerImpl) GetResources ¶ added in v1.27.0
func (m *ManagerImpl) GetResources(pod *v1.Pod, container *v1.Container) (*ContainerInfo, error)
GetResources gets a ContainerInfo object from the claimInfo cache. This information is used by the caller to update a container config.
func (*ManagerImpl) PodMightNeedToUnprepareResources ¶
func (m *ManagerImpl) PodMightNeedToUnprepareResources(UID types.UID) bool
PodMightNeedToUnprepareResources returns true if the pod might need to unprepare resources
func (*ManagerImpl) PrepareResources ¶
func (m *ManagerImpl) PrepareResources(pod *v1.Pod) error
PrepareResources attempts to prepare all of the required resource plugin resources for the input container, issue an NodePrepareResource rpc request for each new resource requirement, process their responses and update the cached containerResources on success.
func (*ManagerImpl) UnprepareResources ¶
func (m *ManagerImpl) UnprepareResources(pod *v1.Pod) error
UnprepareResources calls a plugin's NodeUnprepareResource API for each resource claim owned by a pod. This function is idempotent and may be called multiple times against the same pod. As such, calls to the underlying NodeUnprepareResource API are skipped for claims that have already been successfully unprepared.
