Functions

func ConvertSeed

func ConvertSeed(obj runtime.Object) (*core.Seed, error)

ConvertSeed converts the given external Seed version to an internal version.

func ConvertSeedExternal

func ConvertSeedExternal(obj runtime.Object) (*gardencorev1beta1.Seed, error)

ConvertSeedExternal converts the given internal Seed version to an external version.

func DetermineLatestExpirableVersion

func DetermineLatestExpirableVersion(versions []core.ExpirableVersion, filterPreviewVersions bool) (core.ExpirableVersion, core.ExpirableVersion, error)

DetermineLatestExpirableVersion determines the latest expirable version and the latest non-deprecated version from a slice of ExpirableVersions. When filterPreviewVersions is set, versions with classification preview are not considered.

func DetermineLatestMachineImageVersion

func DetermineLatestMachineImageVersion(versions []core.MachineImageVersion, filterPreviewVersions bool) (core.MachineImageVersion, error)

DetermineLatestMachineImageVersion determines the latest MachineImageVersion from a slice of MachineImageVersion. When filterPreviewVersions is set, versions with classification preview are not considered. It will prefer older but non-deprecated versions over newer but deprecated versions.

func DetermineLatestMachineImageVersions

func DetermineLatestMachineImageVersions(images []core.MachineImage) (map[string]core.MachineImageVersion, error)

DetermineLatestMachineImageVersions determines the latest versions (semVer) of the given machine images from a slice of machine images

func FilterVersionsWithClassification

func FilterVersionsWithClassification(versions []core.ExpirableVersion, classification core.VersionClassification) []core.ExpirableVersion

FilterVersionsWithClassification filters versions for a classification

func FindPrimaryDNSProvider

func FindPrimaryDNSProvider(providers []core.DNSProvider) *core.DNSProvider

FindPrimaryDNSProvider finds the primary provider among the given `providers`. It returns the first provider if multiple candidates are found.

func FindVersionsWithSameMajorMinor

func FindVersionsWithSameMajorMinor(versions []core.ExpirableVersion, version semver.Version) ([]core.ExpirableVersion, error)

FindVersionsWithSameMajorMinor filters the given versions slice for versions other the given one, having the same major and minor version as the given version

func FindWorkerByName

func FindWorkerByName(workers []core.Worker, name string) *core.Worker

FindWorkerByName tries to find the worker with the given name. If it cannot be found it returns nil.

func GetAddedVersions

func GetAddedVersions(old, new []core.ExpirableVersion) map[string]int

GetAddedVersions finds versions that have been added in the new compared to the new version slice. returns a map associating the version with its index in the in the old version slice.

func GetCondition

func GetCondition(conditions []core.Condition, conditionType core.ConditionType) *core.Condition

GetCondition returns the condition with the given <conditionType> out of the list of <conditions>. In case the required type could not be found, it returns nil.

func GetConditionIndex

func GetConditionIndex(conditions []core.Condition, conditionType core.ConditionType) int

GetConditionIndex returns the index of the condition with the given <conditionType> out of the list of <conditions>. In case the required type could not be found, it returns -1.

func GetRemovedVersions

func GetRemovedVersions(old, new []core.ExpirableVersion) map[string]int

GetRemovedVersions finds versions that have been removed in the old compared to the new version slice. returns a map associating the version with its index in the in the old version slice.

func HibernationIsEnabled

func HibernationIsEnabled(shoot *core.Shoot) bool

HibernationIsEnabled checks if the given shoot's desired state is hibernated.

func KubernetesDashboardEnabled

func KubernetesDashboardEnabled(addons *core.Addons) bool

KubernetesDashboardEnabled returns true if the kubernetes-dashboard addon is enabled in the Shoot manifest.

func NginxIngressEnabled

func NginxIngressEnabled(addons *core.Addons) bool

NginxIngressEnabled returns true if the nginx-ingress addon is enabled in the Shoot manifest.

func QuotaScope

func QuotaScope(scopeRef corev1.ObjectReference) (string, error)

QuotaScope returns the scope of a quota scope reference.

func SeedSettingExcessCapacityReservationEnabled

func SeedSettingExcessCapacityReservationEnabled(settings *core.SeedSettings) bool

SeedSettingExcessCapacityReservationEnabled returns true if the 'excess capacity reservation' setting is enabled.

func SeedSettingSchedulingVisible

func SeedSettingSchedulingVisible(settings *core.SeedSettings) bool

SeedSettingSchedulingVisible returns true if the 'scheduling' setting is set to 'visible'.

func SeedSettingShootDNSEnabled

func SeedSettingShootDNSEnabled(settings *core.SeedSettings) bool

SeedSettingShootDNSEnabled returns true if the 'shoot dns' setting is enabled.

func ShootUsesUnmanagedDNS

func ShootUsesUnmanagedDNS(shoot *core.Shoot) bool

ShootUsesUnmanagedDNS returns true if the shoot's DNS section is marked as 'unmanaged'.

func ShootWantsBasicAuthentication

func ShootWantsBasicAuthentication(kubeAPIServerConfig *core.KubeAPIServerConfig) bool

ShootWantsBasicAuthentication returns true if basic authentication is not configured or if it is set explicitly to 'true'.

func ShootWantsVerticalPodAutoscaler

func ShootWantsVerticalPodAutoscaler(shoot *core.Shoot) bool
