How come the elastic agent doesn't shut down when idle?

Karsten Silz

I configured a Bamboo plan in our OnDemand trial. It runs against a Bitbucket Git repository with the "Default Image S3 i386 (linux) (stock image)" and builds fine. However, neither the Elastic Agent nor the EC2 instance shut down when being idle. In the configuration, the "Elastic Instance Management" was set to "Passive", so the "Idle Agent Shutdown Delay" was 10 minutes. And the "Shutdown Delay" for the EC2 instance was set to 300 (seconds, I guess).

However, the agent was idle for about 20 minutes without doing anything. When I manually requested it to stop, it sat there with a "(Stop requested)" message (or similar) for another couple of minutes. Finally, I terminated the instance manually through Bamboo.

So, how do I get the Elastic Agent and the Elastic Instance to shut down after five minutes of idle time?

Kartsen, the automatic instance management will keep the Elastic Agent running for the whole hour that you have paid for so you get the most value out of your agents.

For example, if an EC2 instance costs 18 cents for an hour and you shut it down after using it for only 20 minutes then start another instance it has costed you 36 cents total.

If the instance has been idle and you approach the full hour you have used Bamboo will shut it down before it costs you another hour.

EDIT: On second thoughts, if it got stuck when you requested it to stop then that sounds like a bug. Best bet is to contact OnDemand support.
