Create an OpenStack node using trystack.org provider
----------------------------------------------------

`trystack.org`_ allows users to try out OpenStack for free. This example
demonstrates how to launch an OpenStack node on the ``trystack.org`` provider
using a generic OpenStack driver.

.. sourcecode:: python

    from libcloud.compute.types import Provider
    from libcloud.compute.providers import get_driver

    import libcloud.security

    # At the time this example was written, https://nova-api.trystack.org:5443
    # was using a certificate issued by a Certificate Authority (CA) which is
    # not included in the default Ubuntu certificates bundle (ca-certificates).
    # Note: Code like this poses a security risk (MITM attack) and that's the
    # reason why you should never use it for anything else besides testing. You
    # have been warned.
    libcloud.security.VERIFY_SSL_CERT = False

    OpenStack = get_driver(Provider.OPENSTACK)

    driver = OpenStack('your username', 'your password',
                       ex_force_auth_url='https://nova-api.trystack.org:5443/v2.0',
                       ex_force_auth_version='2.0_password')

    nodes = driver.list_nodes()

    images = driver.list_images()
    sizes = driver.list_sizes()
    size = [s for s in sizes if s.ram == 512][0]
    image = [i for i in images if i.name == 'natty-server-cloudimg-amd64'][0]

    node = driver.create_node(name='test node', image=image, size=size)
