Managing OpenStack instances from Ansible

Ansible provides modules that can manage the OpenStack instance life cycle, just like we did using APIs. You can find the full list of supported modules at http://docs.ansible.com/ansible/latest/modules/list_of_cloud_modules.html#OpenStack.

All OpenStack modules rely on the Python library called shade (https://pypi.python.org/pypi/shade), which provides a wrapper around OpenStack clients.

Once you have installed shade on the automation server, you will have access to the os-* modules that can manipulate the OpenStack configuration, such as os_image (to handle OpenStack images), os_network (to create the network), os_subnet (to create and associate the subnet with the created network), os_nova_flavor (to create flavors, given the RAM, CPU, and disk), and finally, the os_server module (to bring up the OpenStack instance).
