We've got two deployment stacks here, blog, and blog-prod. The blog stack defines
a simple wordpress deploy with mysql and two relations. In this case its
Version 4 bundles are currently under development. The development document for these types of bundles is available here.
Development
Obtain source
$ bzr branch lp:juju-deployer/darwin deployer $ cd deployer
# Test runner $ python setup.py test
Background
This is a wrapper for Juju that allows stack-like configurations of complex deployments. It was created to deploy Openstack but should be able to deploy other complex service configurations in the same manner.
See deployments.cfg and deployments.cfg.sample for examples of how to describe service stacks in JSON.
