Whiteboard

Juju will not live in isolation
https://launchpad.net/juju-jitsu exists to enable these use cases

Potential integration points:

- Existing Puppet Deployments
- Existing puppet subordinate charm promulgated yesterday
- Existing Puppet Manifests
- External Node Classifier
- Capistrano / Fabric
- jitsu capfile -> emits a capfile
- capistrano subordinate?
- Chef
- SaltStack

Solutions
- REST API (lp:jrapi)

other ways to integrate
puppetforge
cookbooks on github
how do you make a charm out of any of these?

User Stories:
Andrew has some nice solid working Chef recipes. He would like to take advantage of the work already done in Chef, and use Juju as a service orchestration mechanism.

Nathan has some existing Puppet deployments that he would like to leverage in Juju's service deployment.

Assumptions:
n/a

Test Plans:
Test Chef, Puppet, Capistrano, CloudStack, and Facter integration points and charms in CharmTester.

Release Notes:
When available provide information on how Chef, Puppet, Capistrano, CloudStack, and Facter may be used in a Juju framework.

-- juju facter integration --
facter is a standalone command tool that can be used via Juju by just installing the package ( sudo apt-get install facter ).
With the addition of facter-customfacts-plugin, new custom "facts" can be added/modified/deleted/used with juju to maintain status of the different aspects of the system in use.
An example of this integration can be found in lp:~negronjl/+junk/hpcc
