Method Detail

findAgentContainersToStart

@NotNull
@NotNull Pair<Collection<ElasticImageConfiguration>,Collection<EphemeralAgentLaunchRequest>> findAgentContainersToStart(boolean elasticsEnabled,
                                                                                                                              boolean ephemeralsEnabled)

Which and how many elastic images should be started.

Returns:

list of elastic image configurations to start

getElasticAgentsToStop

@NotNull
@NotNull Collection<RemoteElasticInstance> getElasticAgentsToStop()

Returns a collection of currently running elastic agents that should be stopped. Current implementation returns the list of elastic instances that - cannot run any of the builds currently in queue - have been idle for longer than ELASTIC_AGENT_IDLE_THRESHOLD - nearing the end of their billing period - didn't have an agent running of them within an hour of startup

Returns:

list of elastic instances that cannot run any of the builds currently in queue
