|
Verify operation of the Image service using
|
|
`CirrOS <http://launchpad.net/cirros>`__, a small
|
|
Linux image that helps you test your OpenStack deployment.
|
|
|
|
For more information about how to download and build images, see
|
|
`OpenStack Virtual Machine Image Guide
|
|
<https://docs.openstack.org/image-guide/>`__.

.. note::
|
|
|
|
Perform these commands on the controller node.
|
|
|
|
#. Source the ``admin`` credentials to gain access to
|
|
admin-only CLI commands:
|
|
|
|
.. code-block:: console
|
|
|
|
$ . admin-openrc
|
|
|
|
.. end
|
|
|
|
#. Download the source image:
|
|
|
|
.. code-block:: console
|
|
|
|
$ wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img
|
|
|
|
.. end
|
|
|
|
.. note::
|
|
|
|
Install ``wget`` if your distribution does not include it.
|
|
|
|
#. Upload the image to the Image service using the
|
|
:term:`QCOW2 <QEMU Copy On Write 2 (QCOW2)>` disk format, :term:`bare`
|
|
container format, and public visibility so all projects can access it:
|
|
|
|
.. code-block:: console
|
|
|
|
$ glance image-create --name "cirros" \
|
|
--file cirros-0.4.0-x86_64-disk.img \
|
|
--disk-format qcow2 --container-format bare \
|
|
--visibility=public
