Functions

func BuildCloudProfileReference

func BuildCloudProfileReference(shoot *core.Shoot) *gardencorev1beta1.CloudProfileReference

BuildCloudProfileReference determines and returns the CloudProfile reference of the given shoot, depending on the availability of cloudProfileName and cloudProfile.

func GetCloudProfileSpec

func GetCloudProfileSpec(cloudProfileLister gardencorev1beta1listers.CloudProfileLister, namespacedCloudProfileLister gardencorev1beta1listers.NamespacedCloudProfileLister, shoot *core.Shoot) (*gardencorev1beta1.CloudProfileSpec, error)

GetCloudProfileSpec determines whether the given shoot references a CloudProfile or a NamespacedCloudProfile and returns the appropriate CloudProfileSpec.

func GetFilteredShootList

func GetFilteredShootList(shootLister gardencorev1beta1listers.ShootLister, predicateFn func(*gardencorev1beta1.Shoot) bool) ([]*gardencorev1beta1.Shoot, error)

GetFilteredShootList returns shoots returned by the shootLister filtered via the predicateFn.

func GetManagedSeed

func GetManagedSeed(ctx context.Context, seedManagementClient versioned.Interface, shootNamespace, shootName string) (*seedmanagementv1alpha1.ManagedSeed, error)

GetManagedSeed gets the ManagedSeed resource for the given shoot namespace and name, by searching for all ManagedSeeds in the shoot namespace that have spec.shoot.name set to the shoot name. If no such ManagedSeeds are found, nil is returned.

func IsSeedUsedByShoot

func IsSeedUsedByShoot(seedName string, shoots []*gardencorev1beta1.Shoot) bool

IsSeedUsedByShoot checks whether there is a shoot cluster referencing the provided seed name

func NewAttributesWithName

func NewAttributesWithName(a admission.Attributes, name string) admission.Attributes

NewAttributesWithName returns admission.Attributes with the given name and all other attributes kept same.

func ProjectForNamespaceFromLister

func ProjectForNamespaceFromLister(projectLister gardencorev1beta1listers.ProjectLister, namespaceName string) (*gardencorev1beta1.Project, error)

ProjectForNamespaceFromLister returns the Project responsible for a given <namespace>. It lists all Projects via the given lister, iterates over them and tries to identify the Project by looking for the namespace name in the project spec.

func SkipVerification

func SkipVerification(operation admission.Operation, metadata metav1.ObjectMeta) bool

SkipVerification is a common function to skip object verification during admission

func SyncCloudProfileFields

func SyncCloudProfileFields(oldShoot, newShoot *core.Shoot)

SyncCloudProfileFields handles the coexistence of a Shoot Spec's cloudProfileName and cloudProfile by making sure both fields are synced correctly and appropriate fallback cases are handled.

func ValidateCloudProfileChanges

func ValidateCloudProfileChanges(namespacedCloudProfileLister gardencorev1beta1listers.NamespacedCloudProfileLister, newShoot, oldShoot *core.Shoot) error

ValidateCloudProfileChanges validates that the referenced CloudProfile does only change towards a more specific reference (i.e. currently only from a CloudProfile to a descendant NamespacedCloudProfile). For now, other changes are not supported (e.g. from one CloudProfile to another or from one NamespacedCloudProfile to another).

func ValidateZoneRemovalFromSeeds

func ValidateZoneRemovalFromSeeds(oldSeedSpec, newSeedSpec *core.SeedSpec, seedName string, shootLister gardencorev1beta1listers.ShootLister, kind string) error

ValidateZoneRemovalFromSeeds returns an error when zones are removed from the old seed while it is still in use by shoots.
