	Steps:    5,
	Duration: 10 * time.Millisecond,

Functions

func RetryOnConflict

func RetryOnConflict(backoff wait.Backoff, fn func() error) error

RetryConflict executes the provided function repeatedly, retrying if the server returns a conflicting write. Callers should preserve previous executions if they wish to retry changes. It performs an exponential backoff.

var pod *api.Pod
err := RetryOnConflict(DefaultBackoff, func() (err error) {
  pod, err = c.Pods("mynamespace").UpdateStatus(podStatus)
  return
})
if err != nil {
  // may be conflict if max retries were hit
  return err
}
