Python bindings to the OpenStack Glance API
=============================================
This is a client for the OpenStack Glance API. There's a Python API (the
``glanceclient`` module), and a command-line script (``glance``). The
Glance 2.0 API is still a moving target, so this module will remain in
"Beta" status until the API is finalized and fully implemented.
Development takes place via the usual OpenStack processes as outlined in
the `OpenStack wiki`_. The master repository is on GitHub__.
__ http://wiki.openstack.org/HowToContribute
__ http://github.com/openstack/python-glanceclient
This code a fork of `Rackspace's python-novaclient`__ which is in turn a fork of
`Jacobian's python-cloudservers`__. The python-glanceclient is licensed under
the Apache License like the rest of OpenStack.

Python API
----------
By way of a quick-start::
# use v2.0 auth with http://example.com:5000/v2.0")
>>> from glanceclient.v2_0 import client
>>> glance = client.Client(username=USERNAME, password=PASSWORD, tenant_name=TENANT, auth_url=KEYSTONE_URL)
>>> glance.images.list()
>>> image = glance.images.create(name="My Test Image")
>>> print image.status
'queued'
>>> image.upload(open('/tmp/myimage.iso', 'rb'))
>>> print image.status
'active'
>>> image_file = image.image_file
>>> with open('/tmp/copyimage.iso', 'wb') as f:
for chunk in image_file:
f.write(chunk)
>>> image.delete()
Command-line API
----------------
Installing this package gets you a command-line tool, ``glance``, that you
can use to interact with Glance's Identity API.
You'll need to provide your OpenStack tenant, username and password. You can do this
with the ``tenant_name``, ``--username`` and ``--password`` params, but it's
easier to just set them as environment variables::
export OS_TENANT_NAME=project
export OS_USERNAME=user
export OS_PASSWORD=pass
You will also need to define the authentication url with ``--auth_url`` and the
version of the API with ``--identity_api_version``. Or set them as an environment
variables as well::
export OS_AUTH_URL=http://example.com:5000/v2.0
export OS_IDENTITY_API_VERSION=2.0
Since the Identity service that Glance uses can return multiple regional image
endpoints in the Service Catalog, you can specify the one you want with
``--region_name`` (or ``export OS_REGION_NAME``).
It defaults to the first in the list returned.
You'll find complete documentation on the shell by running
``glance help``::
usage: glance [--username USERNAME] [--password PASSWORD]
[--tenant_name TENANT_NAME | --tenant_id TENANT_ID]
[--auth_url AUTH_URL] [--region_name REGION_NAME]
[--identity_api_version IDENTITY_API_VERSION]
<subcommand> ...
Command-line interface to the OpenStack Identity API.
