Variables

var (
	ShortPoll        = 1 * time.Second
	ShortPollBackoff = 2.0
	LongPoll         = 15 * time.Minute
)

ShortPoll and LongPoll hold the polling intervals for the instance updater. When a machine has no address or is not started, it will be polled at ShortPoll intervals until it does, exponentially backing off with an exponent of ShortPollBackoff until a maximum(ish) of LongPoll.

When a machine has an address and is started LongPoll will be used to check that the instance address or status has not changed.

Functions

func NewWorker(st *apiinstancepoller.API) worker.Worker

NewWorker returns a worker that keeps track of the machines in the state and polls their instance addresses and status periodically to keep them up to date.
