What would you like to be added?

In func (p *podWorkers) UpdatePod(options UpdatePodOptions) (pod_worker.go):
select {
case podUpdates <- struct{}{}:
default:
}
podUpdates buffer is 1, if the previous update message not finish, the new message will drop without any warning.
User cannot get any idea about this. Event or error/info log should added for debugging.

Why is this needed?

The update pod message drop without any warning.
It is better to add some debug log.
