 Adding an image using the command line
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-Log into the controller node directly to add images using the command
-line with OpenStack command line clients. Glance commands allow users to
-add, manipulate, and manage images.
+The utility container provides a CLI environment for additional
+configuration and management.
 
-Alternatively, configure the environment with administrative access to
-the controller.
+#. Access the utility container:
 
-#. Log into the controller node.
+   .. code::
 
-#. Run the ``openstack image create`` command, and specify the image name.
-   Use the
-   ``--file <The Image File>`` variable to specify the image file.
+      $ lxc-attach -n `lxc-ls -1 | grep utility | head -n 1`
 
-#. Run the ``openstack image set`` command, and specify the image name with the
-   ``--name <The Image Name>`` variable.
+Use the openstack client within the utility container to manage all glance images.
+`See the openstack client official documentation on managing images
+<https://docs.openstack.org/image-guide/create-images-manually.html>`_.
 
-#. View a list of all the images currently available with ``openstack
-   image list``.
-
