RunCleanup runs the cleanup DaemonSet for node-local-dns, waits for its completion, and removes the cleanup label from nodes.

Types

type Interface

type Interface interface {
	component.DeployWaiter
	SetClusterDNS([]string)
	SetDNSServers([]string)
	SetIPFamilies([]gardencorev1beta1.IPFamily)
	SetShootClientSet(kubernetes.Interface)
}

Interface contains functions for a NodeLocalDNS deployer.

func New

func New(
	client client.Client,
	namespace string,
	values Values,
) Interface

New creates a new instance of DeployWaiter for node-local-dns.
