Functions

func ComputeRequiredExtensions added in v1.2.0 

func ComputeRequiredExtensions(shoot *gardencorev1beta1.Shoot, seed *gardencorev1beta1.Seed, controllerRegistrationList []*gardencorev1beta1.ControllerRegistration, internalDomain, externalDomain *garden.Domain) sets.String

ComputeRequiredExtensions compute the extension kind/type combinations that are required for the reconciliation flow.

func ComputeTechnicalID 

func ComputeTechnicalID(projectName string, shoot *gardencorev1beta1.Shoot) string

ComputeTechnicalID determines the technical id of that Shoot which is later used for the name of the namespace and for tagging all the resources created in the infrastructure.

func ConstructExternalClusterDomain 

func ConstructExternalClusterDomain(shoot *gardencorev1beta1.Shoot) *string

ConstructExternalClusterDomain constructs the external Shoot cluster domain, i.e. the domain which will be put into the Kubeconfig handed out to the user.

func ConstructExternalDomain 

func ConstructExternalDomain(ctx context.Context, client client.Client, shoot *gardencorev1beta1.Shoot, shootSecret *corev1.Secret, defaultDomains []*garden.Domain) (*garden.Domain, error)

ConstructExternalDomain constructs an object containing all relevant information of the external domain that shall be used for a shoot cluster - based on the configuration of the Garden cluster and the shoot itself.

func ConstructInternalClusterDomain 

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>".

func IsIncompleteDNSConfigError 

func IsIncompleteDNSConfigError(err error) bool

IsIncompleteDNSConfigError returns true if the error indicates that not the DNS config is incomplete.

func MergeExtensions 

func MergeExtensions(registrations []gardencorev1beta1.ControllerRegistration, extensions []gardencorev1beta1.Extension, namespace string) (map[string]Extension, error)

MergeExtensions merges the given controller registrations with the given extensions, expecting that each type in extensions is also represented in the registration. It ignores all extensions that were explicitly disabled in the shoot spec.
