Currently there is no way to get data onto a volume through the dashboard without taking manual steps in a guest. It's possible to create a volume from a snapshot, but there's no way to get data onto a volume to create the snapshot in the first place. Creating a volume from an image is particularly useful when booting from a volume. This was implemented in cinder and nova-volume in Folsom. Expose this to dashboard users as well. Create a new action for this on the images panel, reusing the 'Create Volume' form. Also make this possible from the volumes panel, by adding a 'source type' field to the 'Create Volume' form. This lets users choose among no source (the default), snapshot, and image, hiding the lists of snapshots and images when the corresponding source type is not selected, similar to the 'image type' field in the 'Launch Instance' workflow. Use the same infrastructure as creating from a snapshot to update the size and name based on the image size and name. Extract the image listing code out of the instance panel, into a generic utility module. Also add a size conversion function, since image sizes are reported by glance in bytes, while volumes are specified in gigabytes.

Horizon (OpenStack Dashboard)
Horizon is a Django-based project aimed at providing a complete
OpenStack Dashboard along with an extensible framework for building new
dashboards from reusable components. The
openstack_dashboard
module is a reference implementation of
a Django site that uses the horizon
app to provide
web-based interactions with the various OpenStack projects.

Dependencies
To get started you will need to install Node.js (http://nodejs.org/) on your machine. Node.js is used with Horizon in order to use LESS (http://lesscss.org/) for our CSS needs. Horizon is currently using Node.js v0.6.12.
For Ubuntu use apt to install Node.js:
$ sudo apt-get install nodejs
For other versions of Linux, please see here:: http://nodejs.org/#download for how to install Node.js on your system.
Getting Started
For local development, first create a virtualenv for the project. In
the tools
directory there is a script to create one for
you:
$ python tools/install_venv.py
Alternatively, the run_tests.sh
script will also install
the environment for you and then run the full test suite to verify
everything is installed and functioning correctly.
Now that the virtualenv is created, you need to configure your local
environment. To do this, create a local_settings.py
file in
the openstack_dashboard/local/
directory. There is a
local_settings.py.example
file there that may be used as a
template.
If all is well you should able to run the development server locally:
$ tools/with_venv.sh manage.py runserver
or, as a shortcut:
$ ./run_tests.sh --runserver
Settings Up OpenStack
The recommended tool for installing and configuring the core OpenStack components is Devstack. Refer to their documentation for getting Nova, Keystone, Glance, etc. up and running.
Note
The minimum required set of OpenStack services running includes the following:
- Nova (compute, api, scheduler, network, and volume services)
- Glance
- Keystone
Optional support is provided for Swift.
Development
For development, start with the getting started instructions above. Once you have a working virtualenv and all the necessary packages, read on.
If dependencies are added to either horizon
or
openstack-dashboard
, they should be added to
tools/pip-requires
.
The run_tests.sh
script invokes tests and analyses on
both of these components in its process, and it is what Jenkins uses to
verify the stability of the project. If run before an environment is set
up, it will ask if you wish to install one.
To run the unit tests:
$ ./run_tests.sh
Building Contributor Documentation
This documentation is written by contributors, for contributors.
The source is maintained in the doc/source
folder using
reStructuredText

Building Automatically:
$ ./run_tests.sh --docs
Building Manually:
$ export DJANGO_SETTINGS_MODULE=local.local_settings $ python doc/generate_autodoc_index.py $ sphinx-build -b html doc/source build/sphinx/html
Results are in the build/sphinx/html directory
