Step 7. Deploying OpenStack from Rally
======================================

Along with supporting already existing OpenStack deployments, Rally itself can **deploy OpenStack automatically** by using one of its *deployment engines*. Take a look at other `deployment configuration file samples <https://github.com/stackforge/rally/tree/master/samples/deployments>`_. For example, *devstack-in-existing-servers.json* is a deployment configuration file that tells Rally to deploy OpenStack with **Devstack** on the existing servers with given credentials:

.. code-block:: none

    {
        "type": "DevstackEngine",
        "provider": {
            "type": "ExistingServers",
            "credentials": [{"user": "root", "host": "10.2.0.8"}]
        }
    }

You can try to deploy OpenStack in your Virtual Machine using this script. Edit the configuration file with your IP address/user name and run, as usual:

.. code-block:: none

   $ rally deployment create --file=samples/deployments/devstack-in-existing-servers.json.json --name=new-devstack
