Constants ¶
const ( // BestGuessMaintenanceMinutes is the average duration of a maintenance operation. It is subtracted from the end // of a maintenance time window to use a best-effort kind of finishing the operation before the end. // Generally, we can't make sure that the maintenance operation is done by the end of the time window anyway (considering large // clusters with hundreds of nodes, a rolling update will take several hours). BestGuessMaintenanceMinutes = 15 )

Types ¶
type CareControlInterface ¶
type CareControlInterface interface {
Care(shoot *gardenv1beta1.Shoot, key string) error
}
CareControlInterface implements the control logic for caring for Shoots. It is implemented as an interface to allow for extensions that provide different semantics. Currently, there is only one implementation.
func NewDefaultCareControl ¶
func NewDefaultCareControl(k8sGardenClient kubernetes.Client, k8sGardenInformers gardeninformers.Interface, secrets map[string]*corev1.Secret, imageVector imagevector.ImageVector, identity *gardenv1beta1.Gardener, config *componentconfig.ControllerManagerConfiguration) CareControlInterface
NewDefaultCareControl returns a new instance of the default implementation CareControlInterface that implements the documented semantics for caring for Shoots. updater is the UpdaterInterface used to update the status of Shoots. You should use an instance returned from NewDefaultCareControl() for any scenario other than testing.
type ControlInterface ¶
type ControlInterface interface {
// ReconcileShoot implements the control logic for Shoot creation, update, and deletion.
// If an implementation returns a non-nil error, the invocation will be retried using a rate-limited strategy.
// Implementors should sink any errors that they do not wish to trigger a retry, and they may feel free to
// exit exceptionally at any point provided they wish the update to be re-run at a later point in time.
// The bool return value determines whether the Shoot should be automatically requeued for reconciliation.
ReconcileShoot(shoot *gardenv1beta1.Shoot, key string) (bool, error)
}
ControlInterface implements the control logic for updating Shoots. It is implemented as an interface to allow for extensions that provide different semantics. Currently, there is only one implementation.
func NewDefaultControl ¶
func NewDefaultControl(k8sGardenClient kubernetes.Client, k8sGardenInformers gardeninformers.Interface, secrets map[string]*corev1.Secret, imageVector imagevector.ImageVector, identity *gardenv1beta1.Gardener, config *componentconfig.ControllerManagerConfiguration, gardenerNamespace string, recorder record.EventRecorder) ControlInterface
NewDefaultControl returns a new instance of the default implementation ControlInterface that implements the documented semantics for Shoots. updater is the UpdaterInterface used to update the status of Shoots. You should use an instance returned from NewDefaultControl() for any scenario other than testing.
type Controller ¶
type Controller struct {
// contains filtered or unexported fields
}
Controller controls Shoots.
func NewShootController ¶
func NewShootController(k8sGardenClient kubernetes.Client, k8sGardenInformers gardeninformers.SharedInformerFactory, kubeInformerFactory kubeinformers.SharedInformerFactory, config *componentconfig.ControllerManagerConfiguration, identity *gardenv1beta1.Gardener, gardenNamespace string, secrets map[string]*corev1.Secret, imageVector imagevector.ImageVector, recorder record.EventRecorder) *Controller
NewShootController takes a Kubernetes client for the Garden clusters <k8sGardenClient>, a struct holding information about the acting Gardener, a <shootInformer>, and a <recorder> for event recording. It creates a new Gardener controller.
func (*Controller) CollectMetrics ¶
func (c *Controller) CollectMetrics(ch chan<- prometheus.Metric)
CollectMetrics implements gardenmetrics.ControllerMetricsCollector interface
func (*Controller) Run ¶
func (c *Controller) Run(ctx context.Context, shootWorkers, shootCareWorkers, shootMaintenanceWorkers, shootQuotaWorkers, shootHibernationWorkers int)
Run runs the Controller until the given stop channel can be read from.
func (*Controller) RunningWorkers ¶
func (c *Controller) RunningWorkers() int
RunningWorkers returns the number of running workers.
type MaintenanceControlInterface ¶
type MaintenanceControlInterface interface {
Maintain(shoot *gardenv1beta1.Shoot, key string) error
}
MaintenanceControlInterface implements the control logic for maintaining Shoots. It is implemented as an interface to allow for extensions that provide different semantics. Currently, there is only one implementation.
func NewDefaultMaintenanceControl ¶
func NewDefaultMaintenanceControl(k8sGardenClient kubernetes.Client, k8sGardenInformers gardeninformers.Interface, secrets map[string]*corev1.Secret, imageVector imagevector.ImageVector, identity *gardenv1beta1.Gardener, recorder record.EventRecorder) MaintenanceControlInterface
NewDefaultMaintenanceControl returns a new instance of the default implementation MaintenanceControlInterface that implements the documented semantics for maintaining Shoots. updater is the UpdaterInterface used to update the spec of Shoots. You should use an instance returned from NewDefaultMaintenanceControl() for any scenario other than testing.
type QuotaControlInterface ¶
type QuotaControlInterface interface {
CheckQuota(shoot *gardenv1beta1.Shoot, key string) error
}
QuotaControlInterface implements the control logic for quota management of Shoots. It is implemented as an interface to allow for extensions that provide different semantics. Currently, there is only one implementation.
func NewDefaultQuotaControl ¶
func NewDefaultQuotaControl(k8sGardenClient kubernetes.Client, k8sGardenInformers gardeninformers.Interface) QuotaControlInterface
NewDefaultQuotaControl returns a new instance of the default implementation of QuotaControlInterface which implements the semantics for controlling the quota handling of Shoot resources.
