func NewRevisionController(
	targetNamespace string,
	configMaps []RevisionResource,
	secrets []RevisionResource,
	kubeInformersForTargetNamespace informers.SharedInformerFactory,
	operatorClient LatestRevisionClient,
	configMapGetter corev1client.ConfigMapsGetter,
	secretGetter corev1client.SecretsGetter,
	eventRecorder events.Recorder,

type StaticPodLatestRevisionClient ¶

type StaticPodLatestRevisionClient struct {
	v1helpers.StaticPodOperatorClient

func (c StaticPodLatestRevisionClient) GetLatestRevisionState() (*operatorv1.OperatorSpec, *operatorv1.OperatorStatus, int32, string, error)

func (c StaticPodLatestRevisionClient) UpdateLatestRevisionOperatorStatus(latestAvailableRevision int32, updateFuncs ...v1helpers.UpdateStatusFunc) (*operatorv1.OperatorStatus, bool, error)
