Constants ¶
const ( // FailedCreatePodReason is added in an event and in a replica set condition // when a pod for a replica set is failed to be created. FailedCreatePodReason = "FailedCreate" // SuccessfulCreatePodReason is added in an event when a pod for a replica set // is successfully created. SuccessfulCreatePodReason = "SuccessfulCreate" // FailedDeletePodReason is added in an event and in a replica set condition // when a pod for a replica set is failed to be deleted. FailedDeletePodReason = "FailedDelete" // SuccessfulDeletePodReason is added in an event when a pod for a replica set // is successfully deleted. SuccessfulDeletePodReason = "SuccessfulDelete" )
Reasons for pod events
const ( // If a watch drops a delete event for a pod, it'll take this long // before a dormant controller waiting for those packets is woken up anyway. It is // specifically targeted at the case where some problem prevents an update // of expectations, without it the controller could stay asleep forever. This should // be set based on the expected latency of watch events. // // Currently a controller can service (create *and* observe the watch events for said // creation) about 10 pods a second, so it takes about 1 min to service // 500 pods. Just creation is limited to 20qps, and watching happens with ~10-30s // latency/pod at the scale of 3000 pods over 100 nodes. ExpectationsTimeout = 5 * time.Minute )
