Shoot is an object containing information about a Shoot cluster.

func (*Shoot) ComputeInClusterAPIServerAddress added in v1.1.0 

func (s *Shoot) ComputeInClusterAPIServerAddress(runsInShootNamespace bool) string

ComputeInClusterAPIServerAddress returns the internal address for the shoot API server depending on whether the caller runs in the shoot namespace or not.

func (*Shoot) ComputeOutOfClusterAPIServerAddress added in v1.1.0 

func (s *Shoot) ComputeOutOfClusterAPIServerAddress(apiServerAddress string, useInternalClusterDomain bool) string

ComputeOutOfClusterAPIServerAddress returns the external address for the shoot API server depending on whether the caller wants to use the internal cluster domain and whether DNS is disabled on this seed.

func (*Shoot) GetDNSRecordComponentsForMigration added in v1.29.0 

func (s *Shoot) GetDNSRecordComponentsForMigration() []component.DeployMigrateWaiter

GetDNSRecordComponentsForMigration returns a list of component.DeployMigrateWaiters of DNSRecord components that should be migrated by the shoot controller.

func (*Shoot) GetExtensionComponentsForParallelMigration added in v1.40.0 

func (s *Shoot) GetExtensionComponentsForParallelMigration() []component.DeployMigrateWaiter

GetExtensionComponentsForParallelMigration returns a list of component.DeployMigrateWaiters of extension components that should be migrated by the shoot controller in parallel. Note that this method does not return ControlPlane and Infrastructure components as they require specific handling during migration.

func (*Shoot) GetInfo added in v1.29.0 

func (s *Shoot) GetInfo() *gardencorev1beta1.Shoot

GetInfo returns the shoot resource of this Shoot in a concurrency safe way. This method should be used only for reading the data of the returned shoot resource. The returned shoot resource MUST NOT BE MODIFIED (except in test code) since this might interfere with other concurrent reads and writes. To properly update the shoot resource of this Shoot use UpdateInfo or UpdateInfoStatus.

func (*Shoot) GetIngressFQDN 

func (s *Shoot) GetIngressFQDN(subDomain string) string

GetIngressFQDN returns the fully qualified domain name of ingress sub-resource for the Shoot cluster. The end result is '<subDomain>.<ingressPrefix>.<clusterDomain>'.

func (s *Shoot) GetMaxNodeCount() int32

GetMaxNodeCount returns the sum of all 'maximum' fields of all worker groups of the Shoot.

func (*Shoot) GetMinNodeCount added in v1.1.0 

func (s *Shoot) GetMinNodeCount() int32

func (s *Shoot) IsShootControlPlaneLoggingEnabled(c *config.GardenletConfiguration) bool

IsShootControlPlaneLoggingEnabled return true if the Shoot controlplane logging is enabled

func (*Shoot) SetInfo added in v1.29.0 

func (s *Shoot) SetInfo(shoot *gardencorev1beta1.Shoot)

SetInfo sets the shoot resource of this Shoot in a concurrency safe way. This method is not protected by a mutex and does not update the shoot resource in the cluster and so should be used only in exceptional situations, or as a convenience in test code. The shoot passed as a parameter MUST NOT BE MODIFIED after the call to SetInfo (except in test code) since this might interfere with other concurrent reads and writes. To properly update the shoot resource of this Shoot use UpdateInfo or UpdateInfoStatus.

func (*Shoot) UpdateInfo added in v1.29.0 

func (s *Shoot) UpdateInfo(ctx context.Context, c client.Client, useStrategicMerge bool, f func(*gardencorev1beta1.Shoot) error) error

UpdateInfo updates the shoot resource of this Shoot in a concurrency safe way, using the given context, client, and mutate function. It copies the current shoot resource and then uses the copy to patch the resource in the cluster using either client.MergeFrom or client.StrategicMergeFrom depending on useStrategicMerge. This method is protected by a mutex, so only a single UpdateInfo or UpdateInfoStatus operation can be executed at any point in time.

func (*Shoot) UpdateInfoStatus added in v1.29.0 

func (s *Shoot) UpdateInfoStatus(ctx context.Context, c client.Client, useStrategicMerge bool, f func(*gardencorev1beta1.Shoot) error) error

UpdateInfoStatus updates the status of the shoot resource of this Shoot in a concurrency safe way, using the given context, client, and mutate function. It copies the current shoot resource and then uses the copy to patch the resource in the cluster using either client.MergeFrom or client.StrategicMergeFrom depending on useStrategicMerge. This method is protected by a mutex, so only a single UpdateInfo or UpdateInfoStatus operation can be executed at any point in time.

type SystemComponents added in v1.13.0 

type SystemComponents struct {
	APIServerProxy      apiserverproxy.Interface
	BlackboxExporter    blackboxexporter.Interface
	ClusterIdentity     clusteridentity.Interface
	CoreDNS             coredns.Interface
	KubeProxy           kubeproxy.Interface
