Constants ¶
const ExtensionDefaultTimeout = 10 * time.Minute
ExtensionDefaultTimeout is the default timeout and defines how long Gardener should wait for a successful reconcilation of this extension resource.

Functions ¶
func ComputeTechnicalID ¶
func ComputeTechnicalID(projectName string, shoot *gardenv1beta1.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 *gardenv1beta1.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 ConstructInternalClusterDomain ¶
ConstructInternalClusterDomain constructs the domain pointing to the kube-apiserver of a Shoot cluster which 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 this domain). In case the given <internalDomain> already contains "internal", the result is constructed as "api.<shootName>.<shootProject>.<internalDomain>." In case it does not, the word "internal" will be appended, resulting in "api.<shootName>.<shootProject>.internal.<internalDomain>".
func MergeExtensions ¶
func MergeExtensions(registrations []corev1alpha1.ControllerRegistration, extensions []gardenv1beta1.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.
Types ¶
type CloudConfig ¶
type CloudConfig struct {
Downloader CloudConfigData
Original CloudConfigData
}
CloudConfig contains a downloader script as well as the original cloud config.
type CloudConfigData ¶
CloudConfigData contains the actual content, a command to load it and all units that shall be considered for restart on change.
type Extension ¶
type Extension struct {
extensionsv1alpha1.Extension
Timeout time.Duration
}
Extension contains information about the extension api resouce as well as configuration information.
type ExternalDomain ¶
ExternalDomain contains information for the used external shoot domain.
func ConstructExternalDomain ¶
func ConstructExternalDomain(ctx context.Context, client client.Client, shoot *gardenv1beta1.Shoot, shootSecret *corev1.Secret, defaultDomains []*garden.DefaultDomain) (*ExternalDomain, 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.
type Shoot ¶
type Shoot struct {
Info *gardenv1beta1.Shoot
Secret *corev1.Secret
CloudProfile *gardenv1beta1.CloudProfile
CloudProvider gardenv1beta1.CloudProvider
SeedNamespace string
KubernetesMajorMinorVersion string
InternalClusterDomain string
ExternalClusterDomain *string
ExternalDomain *ExternalDomain
WantsClusterAutoscaler bool
WantsAlertmanager bool
IgnoreAlerts bool
IsHibernated bool
CloudConfigMap map[string]CloudConfig
Extensions map[string]Extension
InfrastructureStatus []byte
MachineDeployments []extensionsv1alpha1.MachineDeployment
}
Shoot is an object containing information about a Shoot cluster.
func New ¶
func New(k8sGardenClient kubernetes.Interface, k8sGardenInformers gardeninformers.Interface, shoot *gardenv1beta1.Shoot, projectName, internalDomain string, defaultDomains []*garden.DefaultDomain) (*Shoot, error)
New takes a <k8sGardenClient>, the <k8sGardenInformers> and a <shoot> manifest, and creates a new Shoot representation. It will add the CloudProfile, the cloud provider secret, compute the internal cluster domain and identify the cloud provider.
func (*Shoot) ClusterAutoscalerEnabled ¶
ClusterAutoscalerEnabled returns true if the cluster-autoscaler addon is enabled in the Shoot manifest.
func (*Shoot) ComputeAPIServerURL ¶
ComputeAPIServerURL takes a boolean value identifying whether the component connecting to the API server runs in the Seed cluster <runsInSeed>, and a boolean value <useInternalClusterDomain> which determines whether the internal or the external cluster domain should be used.
func (*Shoot) ComputeCloudConfigSecretName ¶
ComputeCloudConfigSecretName computes the name for a secret which contains the original cloud config for the worker group with the given <workerName>. It is build by the cloud config secret prefix, the worker name itself and a hash of the minor Kubernetes version of the Shoot cluster.
func (*Shoot) GetIngressFQDN ¶
GetIngressFQDN returns the fully qualified domain name of ingress sub-resource for the Shoot cluster. The end result is '<subDomain>.<ingressPrefix>.<clusterDomain>'.
func (*Shoot) GetK8SNetworks ¶
func (s *Shoot) GetK8SNetworks() (*gardencorev1alpha1.K8SNetworks, error)
GetK8SNetworks returns the Kubernetes network CIDRs for the Shoot cluster.
func (*Shoot) GetMachineImage ¶
func (s *Shoot) GetMachineImage() *gardenv1beta1.MachineImage
GetMachineImage returns the name of the used machine image.
func (*Shoot) GetMachineTypesFromCloudProfile ¶
func (s *Shoot) GetMachineTypesFromCloudProfile() []gardenv1beta1.MachineType
GetMachineTypesFromCloudProfile returns a list of machine types in the cloud profile.
func (*Shoot) GetNodeCount ¶
GetNodeCount returns the sum of all 'autoScalerMax' fields of all worker groups of the Shoot.
func (*Shoot) GetNodeNetwork ¶
func (s *Shoot) GetNodeNetwork() gardencorev1alpha1.CIDR
GetNodeNetwork returns the node network CIDR for the Shoot cluster.
func (*Shoot) GetPodNetwork ¶
func (s *Shoot) GetPodNetwork() gardencorev1alpha1.CIDR
GetPodNetwork returns the pod network CIDR for the Shoot cluster.
func (*Shoot) GetReplicas ¶
GetReplicas returns the given <wokenUp> number if the shoot is not hibernated, or zero otherwise.
func (*Shoot) GetServiceNetwork ¶
func (s *Shoot) GetServiceNetwork() gardencorev1alpha1.CIDR
GetServiceNetwork returns the service network CIDR for the Shoot cluster.
func (*Shoot) GetWorkerNames ¶
GetWorkerNames returns a list of names of the worker groups in the Shoot manifest.
func (*Shoot) GetWorkerVolumesByName ¶
func (s *Shoot) GetWorkerVolumesByName(workerName string) (ok bool, volumeType, volumeSize string, err error)
GetWorkerVolumesByName returns the volume information for the specific worker pool (if there is any volume information).
func (*Shoot) GetWorkers ¶
func (s *Shoot) GetWorkers() []gardenv1beta1.Worker
GetWorkers returns a list of worker objects of the worker groups in the Shoot manifest.
func (*Shoot) IPVSEnabled ¶
IPVSEnabled returns true if IPVS is enabled for the shoot.
func (*Shoot) Kube2IAMEnabled ¶
Kube2IAMEnabled returns true if the kube2iam addon is enabled in the Shoot manifest.
func (*Shoot) KubeLegoEnabled ¶
KubeLegoEnabled returns true if the kube-lego addon is enabled in the Shoot manifest.
func (*Shoot) KubernetesDashboardEnabled ¶
KubernetesDashboardEnabled returns true if the kubernetes-dashboard addon is enabled in the Shoot manifest.
func (*Shoot) NginxIngressEnabled ¶
