func CentralLoggingConfiguration() (component.CentralLoggingConfig, error)

CentralLoggingConfiguration returns a fluent-bit parser and filter for the CoreDNS logs.

Types

type Interface

type Interface interface {
	component.DeployWaiter
	SetPodAnnotations(map[string]string)
	SetNodeNetworkCIDRs([]net.IPNet)
	SetPodNetworkCIDRs([]net.IPNet)
	SetClusterIPs([]net.IP)
	SetIPFamilies([]gardencorev1beta1.IPFamily)
}

Interface contains functions for a CoreDNS deployer.

func New

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

New creates a new instance of DeployWaiter for coredns.
