Overview

Package controller contains code for controllers (like the replication controller).

Constants

Reasons for pod events

View Source 
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

The desired behavior is to treat an update that sets the DeletionTimestamp on an object as a delete. To do so consistenly, one needs to remember the expected deletes so they aren't double counted. TODO: Track creates as well (#22599)
