Puppet users - Nov 2010 - Query facter 'facts' from webapp

Hi,

I would like to query the puppetmaster (or the puppet nodes...) for some facts
and display/use these in an external web application (written django)
using the certificates from Puppet.

What''s the correct (nice) way to do this? REST?
Can I find some code examples for this?

Met vriendelijke groeten,
Pieter Baele

Hi,

I''m looking at doing a similar thing for Edison [0] (also written in
Django!).

For the moment, I''ve written "pyfacter" - a basic python
wrapper around the
command line [1] - however I''d like to improve on this if possible.

One thing I was planning on looking at was writing a python client for 
MCollective and using the audit tools available as part of MC to collect the 
facts either into a database or at runtime but that requires the ability to 
use Python with MC (nudge @rip :P)

The only other solution I can think of is a cronjob that runs on each host on 
a regular basis and posts/puts to an API to fill the relevant field in the 
database.

Kind regards,

Matt

My suggestion would be to use storeconfigs and just read the facts from the
db.
The structure of the db is quite simple.

You could query foreman to get the facts via rest, see :

Puppet 2.6.1+ has a Fact CouchDB REST terminus you can use to do this.

Pieter, It''s not a solution today but it sounds like you''re
looking
for the Inventory Service[1]. The basic idea is to collect, and
export, the client facts using a REST interface from a central
service. There''s a push to get this in to 2.7[2], so some of your work
may be done for you already.

The mcollective registration method also works great, if you want to
go that route.

We just demo''ed the Inventory Service internally this morning and it
works brilliantly - support for it will be in 2.7.0 and in Dashboard 1.0.5.

Just a thought if you are doing end of iteration showcases, maybe
knocking up screen shots of new upcoming shinyness would be
interesting for those unable to be physically present.

Absolutely.

We''re working out a way to do decent screencasts of new and existing
features.

Would people be interested in tuning into such demos live? I
understand we have a rather wide spread of timezones here, but it
would be kind of cool if we could do live demos to our whole community
with questions over IRC.

Live might be too hard :( but I''d be very keen to try anyway, failing
that screencasts are great, I''m a big fan.

That''s the plan going forward is to produce videos on the demos.

Yeah live demos are hard - I''d probably avoid unless it''s a
proper
rehearsed launch/talk type thing (even then I''d have back up for if
live broke).

Getting stuff out early, with a demo and an easy way to clone/play
with might help get wider testing of features. Particularly for stuff
which people are going to interact with.
