Types ¶
type CRBStatusController ¶ added in v1.6.0
type CRBStatusController struct {
client.Client // used to operate ClusterResourceBinding resources.
DynamicClient dynamic.Interface // used to fetch arbitrary resources from api server.
InformerManager genericmanager.SingleClusterInformerManager // used to fetch arbitrary resources from cache.
EventRecorder record.EventRecorder
RESTMapper meta.RESTMapper
ResourceInterpreter resourceinterpreter.ResourceInterpreter
RateLimiterOptions ratelimiterflag.Options
}
CRBStatusController is to sync status of ClusterResourceBinding and aggregate status to the resource template.
func (*CRBStatusController) Reconcile ¶ added in v1.6.0
func (c *CRBStatusController) Reconcile(ctx context.Context, req controllerruntime.Request) (controllerruntime.Result, error)
Reconcile performs a full reconciliation for the object referred to by the Request. The Controller will requeue the Request to be processed again if an error is non-nil or Result.Requeue is true, otherwise upon completion it will remove the work from the queue.
func (*CRBStatusController) SetupWithManager ¶ added in v1.6.0
func (c *CRBStatusController) SetupWithManager(mgr controllerruntime.Manager) error
SetupWithManager creates a controller and register to controller manager.

// ClusterClientOption holds the attributes that should be injected to a Kubernetes client.
ClusterClientOption *util.ClientOption
// ClusterStatusUpdateFrequency is the frequency that controller computes and report cluster status.
ClusterStatusUpdateFrequency metav1.Duration
// ClusterLeaseDuration is a duration that candidates for a lease need to wait to force acquire it.
// This is measure against time of last observed lease RenewTime.
ClusterLeaseDuration metav1.Duration
// ClusterLeaseRenewIntervalFraction is a fraction coordinated with ClusterLeaseDuration that
// how long the current holder of a lease has last updated the lease.
ClusterLeaseRenewIntervalFraction float64
// ClusterLeaseControllers stores context canceler function for each lease controller.
// Each lease controller is started with a separated context.
// key: cluster name of the lease controller servers for.
// value: context canceler function to stop the controller after cluster is un-registered.
ClusterLeaseControllers sync.Map
// ClusterSuccessThreshold is the duration of successes for the cluster to be considered healthy after recovery.
ClusterSuccessThreshold metav1.Duration
// ClusterFailureThreshold is the duration of failure for the cluster to be considered unhealthy.
ClusterFailureThreshold metav1.Duration
ClusterCacheSyncTimeout metav1.Duration
RateLimiterOptions ratelimiterflag.Options
// EnableClusterResourceModeling indicates if enable cluster resource modeling.
// The resource modeling might be used by the scheduler to make scheduling decisions
// in scenario of dynamic replica assignment based on cluster free resources.
// Disable if it does not fit your cases for better performance.
EnableClusterResourceModeling bool
// contains filtered or unexported fields
}
ClusterStatusController is to sync status of Cluster.
func (*ClusterStatusController) Reconcile ¶ added in v0.3.0
func (c *ClusterStatusController) Reconcile(ctx context.Context, req controllerruntime.Request) (controllerruntime.Result, error)
Reconcile syncs status of the given member cluster. The Controller will requeue the Request to be processed again if an error is non-nil or Result.Requeue is true, otherwise upon completion it will requeue the reconcile key after the duration.
