HA for fully-automatic egress IPs #20485

Merged

Conversation

Tracks node online/offline state and handles reassigning egress IPs as needed.

The tracking code is very similar to the semi-automatic tracking code, but couldn't easily be shared since we don't do the OVS flow tracking in this case. Like the semi-automatic code, it needs to be made more configurable at some point...

Would it be more idomatic to do something like:

var timeout time.Duration
select {
case <-stop:
	return
case <-time.After(timeout):
	start := time.Now()
	retry := eim.check(retry)
	if !retry {
		//  If less than pollInterval has passed since start, then sleep until it has
		timeout = time.Until(start.Add(pollInterval))
	}
}
