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 container in a pod.
// It communicates with the DRA resource plugin to prepare resources and
// returns resource info to trigger CDI injection by the runtime.
PrepareResources(pod *v1.Pod, container *v1.Container) (*ContainerInfo, error)
// UnprepareResources calls NodeUnprepareResource GRPC from DRA plugin to unprepare pod resources
UnprepareResources(pod *v1.Pod) 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) 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, container *v1.Container) (*ContainerInfo, error)
PrepareResources calls plugin NodePrepareResource from the registered DRA resource plugins.
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.
