func ReadConfigMapValue(clientset kubernetes.Interface, namespace string, name string, key string) (string, error)

Types

type Throttler

type Throttler interface {
	Add(key interface{}, priority int32, creationTime time.Time)
	// Next returns true if item should be processed by controller now or return false.
	Next(key interface{}) (interface{}, bool)
	// Remove notifies throttler that item processing is done. In responses the throttler triggers processing of previously throttled items.
	Remove(key interface{})
	// SetParallelism update throttler parallelism limit.
	SetParallelism(parallelism int)
}

Throttler allows CRD controller to limit number of items it is processing in parallel.

func NewThrottler

func NewThrottler(parallelism int, queue workqueue.RateLimitingInterface) Throttler

type WorkflowController

type WorkflowController struct {

	// Config is the workflow controller's configuration
	Config config.WorkflowControllerConfig
	// contains filtered or unexported fields
}
