Auto-scale Rackspace Cloud servers with Fabric and Celery

GETTING STARTED

You must edit auto-scale.py, fabfile.py, tasks.py, and conf/settings.py to fit your project
conf/settings.py
- Set your Rackspace Cloud API details
  - CLOUDSERVERS_USERNAME, CLOUDSERVERS_API_KEY
- Set CLOUDSERVERS_IMAGE_TEMPLATE to the name of your Cloud Servers saved image backup snapshot
auto-scale.py
- Set your rabbitmq vhost details in: get_rabbitmq_queue_size()
  - Currently: project_vhost
- Set the path to fabric and your fabfile.py in: start_workers_with_fabric()
  - Currently: /opt/codebase/auto-scale/fabfile.py
fabfile.py
- Set your new worker naming convention in: _create_server()
  - Currently: server_name = 'worker-%s' % (get_uuid)
- Set path to your codebase that will rsync to new worker in: _rsync_codebase_to_worker()
  - Currently: /opt/codebase/ in the call() to rsync
- The deploy_worker() does most of the work

Use conf/settings.py to define additional settings:
- Code base path
- Snapshot image template name
- Paths to Fabric and fabfile.py in auto-scale.py
- RabbitMQ vhost name
