Functions

func CheckDuplicate

func CheckDuplicate(list []string) []string

CheckDuplicate finds if there are duplicated items in a list.

func GetOrdinal

func GetOrdinal(pod *corev1.Pod) int32

func IsControllerEnabled

func IsControllerEnabled(name string, controllers []string) bool

IsControllerEnabled check if a specified controller enabled or not.

func SlowStartBatch

func SlowStartBatch(count int, initialBatchSize int, fn func(index int) error) (int, error)

SlowStartBatch tries to call the provided function a total of 'count' times, starting slow to check for errors, then speeding up if calls succeed.

It groups the calls into batches, starting with a group of initialBatchSize. Within each batch, it may call the function multiple times concurrently with its index.

If a whole batch succeeds, the next batch may get exponentially larger. If there are any failures in a batch, all remaining batches are skipped after waiting for the current batch to complete.

It returns the number of successful calls to the function.
