Overview ¶
Package util contains helpers for building controllers. It does not contain any controllers by itself.

Functions ¶
func ClusterAvailableForReconciling ¶
func ClusterAvailableForReconciling(ctx context.Context, client ctrlruntimeclient.Client, cluster *kubermaticv1.Cluster, concurrencyLimit int) (bool, error)
ClusterAvailableForReconciling returns true if the given cluster can be reconciled. This is true if the cluster does not yet have the SeedResourcesUpToDate condition or if the concurrency limit of the controller is not yet reached. This ensures that not too many cluster updates are running at the same time, but also makes sure that un-UpToDate clusters will continue to be reconciled.
func ConcurrencyLimitReached ¶
func ConcurrencyLimitReached(ctx context.Context, client ctrlruntimeclient.Client, limit int) (bool, error)
ConcurrencyLimitReached checks all the clusters inside the seed cluster and checks for the SeedResourcesUpToDate condition. Returns true if the number of clusters without this condition is equal or larger than the given limit.
func EnqueueClusterForNamespacedObject ¶
func EnqueueClusterForNamespacedObject(client ctrlruntimeclient.Client) handler.EventHandler
EnqueueClusterForNamespacedObject enqueues the cluster that owns a namespaced object, if any It is used by various controllers to react to changes in the resources in the cluster namespace
func EnqueueClusterForNamespacedObjectWithSeedName ¶
func EnqueueClusterForNamespacedObjectWithSeedName(client ctrlruntimeclient.Client, seedName string, clusterSelector labels.Selector) handler.EventHandler
EnqueueClusterForNamespacedObjectWithSeedName enqueues the cluster that owns a namespaced object, if any. The seedName is put into the namespace field It is used by various controllers to react to changes in the resources in the cluster namespace
func EnqueueClusterScopedObjectWithSeedName ¶
func EnqueueClusterScopedObjectWithSeedName(seedName string) handler.EventHandler
EnqueueClusterScopedObjectWithSeedName enqueues a cluster-scoped object with the seedName as namespace. If it gets an object with a non-empty name, it will log an error and not enqueue anything.
func EnqueueConst ¶
func EnqueueConst(queueKey string) handler.EventHandler
EnqueueConst enqueues a constant. It is meant for controllers that don't have a parent object they could enc and instead reconcile everything at once. The queueKey will be defaulted if empty
func IsCacheNotStarted ¶
IsCacheNotStarted returns true if the given error is not nil and an instance of cache.ErrCacheNotStarted.
