Types

type BaseControllerRefManager 

type BaseControllerRefManager struct {
	Controller metav1.Object
	Selector   labels.Selector

	CanAdoptFunc func() error
	// contains filtered or unexported fields
}

func (*BaseControllerRefManager) CanAdopt

func (*BaseControllerRefManager) ClaimObject 

func (m *BaseControllerRefManager) ClaimObject(obj metav1.Object, match func(metav1.Object) bool, adopt, release func(metav1.Object) error) (bool, error)

ClaimObject tries to take ownership of an object for this controller.

It will reconcile the following:

  • Adopt orphans if the match function returns true.
  • Release owned objects if the match function returns false.

A non-nil error is returned if some form of reconciliation was attempted and failed. Usually, controllers should try again later in case reconciliation is still needed.

If the error is nil, either the reconciliation succeeded, or no reconciliation was necessary. The returned boolean indicates whether you now own the object.

No reconciliation will be attempted if the controller is being deleted.

type ConfigMapControlInterface 

type ConfigMapControlInterface interface {
	// CreateConfigMap creates new Services according to the spec.

	podControl PodControlInterface,
	controller metav1.Object,
	selector labels.Selector,
	controllerKind schema.GroupVersionKind,
	canAdopt func() error,
) *PodControllerRefManager

NewPodControllerRefManager returns a PodControllerRefManager that exposes methods to manage the controllerRef of pods.

The CanAdopt() function can be used to perform a potentially expensive check (such as a live GET from the API server) prior to the first adoption. It will only be called (at most once) if an adoption is actually attempted. If CanAdopt() returns a non-nil error, all adoptions will fail.

NOTE: Once CanAdopt() is called, it will not be called again by the same 

PodControllerRefManager instance. Create a new instance if it makes
sense to check CanAdopt() again (e.g. in a different sync pass).

func (*PodControllerRefManager) AdoptPod 

func (m *PodControllerRefManager) AdoptPod(pod *v1.Pod) error

func (m *PodControllerRefManager) ClaimPods(pods []*v1.Pod, filters ...func(*v1.Pod) bool) ([]*v1.Pod, error)

ClaimPods tries to take ownership of a list of Pods.

It will reconcile the following:

  • Adopt orphans if the selector matches.
  • Release owned objects if the selector no longer matches.

Optional: If one or more filters are specified, a Pod will only be claimed if all filters return true.

A non-nil error is returned if some form of reconciliation was attempted and failed. Usually, controllers should try again later in case reconciliation is still needed.

If the error is nil, either the reconciliation succeeded, or no reconciliation was necessary. The list of Pods that you now own is returned.

func (*PodControllerRefManager) ReleasePod 

func (m *PodControllerRefManager) ReleasePod(pod *v1.Pod) error

ReleasePod sends a patch to free the pod from the control of the controller. It returns the error if the patching fails. 404 and 422 errors are ignored.
