[Supervisor-users] config from database

[Chris Withers]

Hi All,

I wondered if there were standard ways or, failing that, if anyone had
any ways to get the process configuration used by supervisor to come
from a database rather than a static file on disk?

cheers,

Chris

Have you checked out the supervisor_twiddler
<https://github.com/mnaberez/supervisor_twiddler> plugin? From its docs:

There are times when it is useful to be able to dynamically add and remove

process configurations on a supervisord instance. This is the functionality
that supervisor_twiddler provides. After restarting supervisord, the
changes made by supervisor_twiddler will not persist.

So, with the plugin installed, you could create a process that reads data
from an external source and updates the supervisor configuration through
the xmlrpclib API. Your config process could either run continuously, or
you could set it up as an event listener
<http://supervisord.org/events.html#configuring-an-event-listener> to have
supervisor run it periodically.

Yep, this was my fallback, I was just wondering if there was anything
more complete.

What event would you recommend it listens to?

I was thinking you'd just listen for a tick to periodically check for
changed.
