Types

type ClusterEvent

type ClusterEvent struct {
	EventTime time.Time
	UID       types.UID
	EventType EventType
	OldSpec   *acidv1.Postgresql
	NewSpec   *acidv1.Postgresql
	WorkerID  uint32
}

ClusterEvent carries the payload of the Cluster TPR events.

type Controller

type Controller struct {
	KubeClient k8sutil.KubernetesClient

	PodServiceAccount            *v1.ServiceAccount
	PodServiceAccountRoleBinding *rbacv1.RoleBinding
	// contains filtered or unexported fields
}

Controller represents operator controller

func NewController
