Generalize Services Management

Registered by Duncan McGreggor on 2012-03-16

"Classic" devstack uses screen to start and manage services in the development environment the script creates. Devstackpy seeks to provide a perfectly analogous setup and development process, so we definitely want to provide this option. However, with the added flexibility of using the Python version to custom-install a dev environment, it would be nice to also have the option of:
 * starting/stopping/etc services in a custom manner
 * view logs and tracebacks in a custom manner

This blueprint aims to track the work that is required to make this a reality.

Whiteboard

Investigate the following options for managing/watchdogging processes:
  Upstart (preferred, since this is what comes with Ubuntu and will ship on 12.04 LTS)
  Circus (http://tarekziade.wordpress.com/2012/02/24/circus-a-process-controller)
  Supervisord (http://supervisord.org/)

(?)

Work Items

Work items:
Determine if Upstart will suite our needs: TODO
If it doesn't, we need to clearly document why and confirm with Scott James Remnant that Upstart can't do what we need: TODO
If we can't use Upstart, then we can examine our options: TODO
Investigate systemd: TODO
Investigate Circus: TODO
Investigate Supervisord: TODO
