Functions

func AddIstioIngressGateway

func AddIstioIngressGateway(
	istioDeployer istio.Interface,
	namespace string,
	annotations map[string]string,
	labels map[string]string,
	externalTrafficPolicy *corev1.ServiceExternalTrafficPolicyType,
	serviceExternalIP *string,
	zone *string,
) error

AddIstioIngressGateway adds an Istio ingress gateway to the given deployer. It uses the first Ingress Gateway to fill out common chart values. Hence, it is assumed that at least one Ingress Gateway was added to the given `istioDeployer` before calling this function.

func DeployKubeAPIServer

func DeployKubeAPIServer(
	ctx context.Context,
	runtimeClient client.Client,

) error

DeployKubeAPIServer deploys the Kubernetes API server.

func GetIstioNamespaceForZone

func GetIstioNamespaceForZone(defaultNamespace string, zone string) string

GetIstioNamespaceForZone returns the namespace to use for a given zone. In case the zone name is too long the first five characters of the hash of the zone are used as zone identifiers.

func GetIstioZoneLabels

func GetIstioZoneLabels(labels map[string]string, zone *string) map[string]string

GetIstioZoneLabels returns the labels to be used for istio with the mandatory zone label set.

func IsZonalIstioExtension

func IsZonalIstioExtension(labels map[string]string) (bool, string)

IsZonalIstioExtension indicates whether the namespace related to the given labels is a zonal istio extension. It also returns the zone.

func NewEtcdDruid

func NewEtcdDruid(
