Ideally every cloud module would support an exact_count like was done for Rackspace and EC2, where it makes that number of containers exist. Though I'm a little unclear why you'd want multiple docker containers on the same host, the way that sucker runs (i.e. it's not a cloud API so those images get all on the same box). --Michael On Wed, Apr 16, 2014 at 10:09 PM, Patrick Galbraith <[email protected]> wrote: > Thanks!
