Variables ¶

var DefaultBackoff = wait.Backoff{
	Steps:    4,
	Duration: 10 * time.Millisecond,
	Factor:   5.0,
	Jitter:   0.1,
}

DefaultBackoff is the recommended backoff for a conflict where a client may be attempting to make an unrelated modification to a resource under active management by one or more controllers.

var DefaultRetry = wait.Backoff{
	Steps:    5,
	Duration: 10 * time.Millisecond,
	Factor:   1.0,
	Jitter:   0.1,
}

DefaultRetry is the recommended retry for a conflict where multiple clients are making changes to the same resource.

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
}
...
