How can I prevent TeamCity Cloud Agents (running on Amzon EC2) from leaving defunct volume snapshots when they terminate?

Question

I've recently set up TeamCity to use agents running on Amazon EC2. I've been using it for a week or so and noticed my bill was racking up quite quickly. When I looked in my dashboard I had 30 or so snapshots, which I presume I'm being charged for.

TeamCity starts agents on demand and stops them when they've been idle for about an hour. At that point, the instance is deleted. I would expect the corresponding snapshot to be deleted too, but that doesn't seem to be happening, they are piling up like zombies!

When setting this up I followed Roy Osherove's guide and I tried to follow to the letter, but I'm sure I must have missed something. Does anyone know where I went wrong?

Answer 1

you can create a special teamcity-agent image, when add esb volume, check the "Delete on Termination" checkbox.
