Types

type Interface

type Interface interface {
	gardenercomponent.DeployWaiter
	// Get gets the etcd StatefulSet.
	Get(context.Context) (*appsv1.StatefulSet, error)
}

Interface contains functions for a StatefulSet deployer.

func New

func New(c client.Client, logger logr.Logger, values Values) Interface

New creates a new statefulset deployer instance.

func GenerateValues

func GenerateValues(
	etcd *druidv1alpha1.Etcd,
	clientPort, serverPort, backupPort *int32,
	etcdImage, backupImage string,
	checksumAnnotations map[string]string,
	peerTLSChangedToEnabled bool) Values

GenerateValues generates `statefulset.Values` for the statefulset component with the given parameters.
