func ConstructExternalClusterDomain Uses

func ConstructExternalClusterDomain(shoot *gardencorev1beta1.Shoot) *string

func ConstructInternalClusterDomain Uses

func ConstructInternalClusterDomain(shootName, shootProject string, internalDomain *garden.Domain) string

ConstructInternalClusterDomain constructs the internal base domain pof this shoot cluster. It is only used for internal purposes (all kubeconfigs except the one which is received by the user will only talk with the kube-apiserver via a DNS record of domain). In case the given <internalDomain> already contains "internal", the result is constructed as "<shootName>.<shootProject>.<internalDomain>." In case it does not, the word "internal" will be appended, resulting in "<shootName>.<shootProject>.internal.<internalDomain>".
