Types

type Access

type Access struct {
	Client        client.Client
	Clientset     *k8sclient.Clientset
	Scheme        *runtime.Scheme
	EventRecorder record.EventRecorder
}

Access provides client related structs to access kubernetes

func (*Access) CreateWithReference

func (a *Access) CreateWithReference(ctx context.Context, object, owner metav1.Object) error

CreateWithReference method creates a kubernetes resource and sets the owner reference to a given object. It provides basic idempotency (by ignoring Already Exists errors). Successful creation of the event is logged via EventRecorder to the owner.

func (*Access) DeleteObject

func (a *Access) DeleteObject(ctx context.Context, object, owner metav1.Object) error

DeleteObject method deletes a kubernetes resource while ignores not found errors, so that it can be called multiple times. Successful deletion of the event is logged via EventRecorder to the owner.
