Functions

func ComputeRequiredExtensions added in v1.2.0

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.

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.

func ComputeConditionStatus added in v1.12.0 

func ComputeConditionStatus(conditions ...gardencorev1beta1.Condition) Status

ComputeConditionStatus computes a shoot Label Status from the given Conditions. By default, the Status is StatusHealthy. The condition status is converted to a Status by using ConditionStatusToStatus. Always the worst status of the combined states wins.
