Manage images

=============

When working with images in the SDK, you will call both ``glance`` and
|
|
``nova`` methods.
|
|
|
|
.. _list-images:
|
|
|
|
List images
|
|
~~~~~~~~~~~
|
|
|
|
To list the available images, call the
|
|
``glanceclient.v2.images.Controller.list`` method:
|
|
|
|
.. code-block:: python
|
|
|
|
import glanceclient.v2.client as glclient
|
|
glance = glclient.Client(...)
|
|
images = glance.images.list()
|
|
|
|
The images method returns a Python generator, as shown in the following
|
|
interaction with the Python interpreter:
|
|
|
|
.. code-block:: python
|
|
|
|
>>> images = glance.images.list()
|
|
>>> images
|
|
<generator object list at 0x105e9c2d0>
|
|
>>> list(images)

.. _get-image-id:
|
|
|
|
Get image by ID
|
|
~~~~~~~~~~~~~~~
|
|
|
|
To retrieve an image object from its ID, call the
|
|
``glanceclient.v2.images.Controller.get`` method:
|
|
|
|
.. code-block:: python
|
|
|
|
import glanceclient.v2.client as glclient
|
|
image_id = 'c002c82e-2cfa-4952-8461-2095b69c18a6'
|
|
glance = glclient.Client(...)
|
|
image = glance.images.get(image_id)
|
|
|
|
.. _get-image-name:
|
|
|
|
Get image by name
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
The Image service Python bindings do not support the retrieval of an
|
|
image object by name. However, the Compute Python bindings enable you to
|
|
get an image object by name. To get an image object by name, call the
|
|
``novaclient.v1_1.images.ImageManager.find`` method:
|
|
|
|
.. code-block:: python
|
|
|
|
import novaclient.v1_1.client as nvclient
|
|
name = "cirros"
|
|
nova = nvclient.Client(...)
|
|
image = nova.images.find(name=name)
|
|
|
|
.. _upload-image:
|
|
|
|
Upload an image
|
|
~~~~~~~~~~~~~~~
|
|
|
|
To upload an image, call the ``glanceclient.v2.images.ImageManager.create``
|
|
method:
|
|
|
|
.. code-block:: python
|
|
|
|
import glanceclient.v2.client as glclient
|
|
imagefile = "/tmp/myimage.img"
|
|
glance = glclient.Client(...)
|
|
with open(imagefile) as fimage:
|
|
glance.images.create(name="myimage", is_public=False, disk_format="qcow2",
|
|
container_format="bare", data=fimage)
