OpenStack Image Management (Glance)

Michael Still 7335088d89 Handle images which exist but can't be seen.
If the master and the slave glance have different permissions, you
can end up with a 409 exception at upload. For example:

 - the image is visible to the replication user on the master
 - the image is present on the slave, but not visible to the
   replication user

The replicator checks for the existance of the image by doing a HEAD
on http://server:port/v1/images/uuid and gets a 404 back. It therefore
decides the image doesn't exist and that it should be replicated. It
does a POST for that URL, and gets a 409 back saying that UUID is
already in use.

Resolves bug 1030396.

Glance

Glance is a project that defines services for discovering, registering, retrieving and storing virtual machine images. The discovery and registration responsibilities are handled by the glance-registry component while the retrieval and storage responsiblities are handled by the glance-api component.

Quick Start

If you'd like to run trunk, you can clone the git repo:

git clone git@github.com:openstack/glance.git

Install Glance by running:

python setup.py build
sudo python setup.py install

By default, glance-registry will use a SQLite database. If you'd like to use MySQL, or make other adjustments, you can modify the glance.cnf file (see documentation for more details).

Now that Glance is installed, you can start the service. The easiest way to do that is by using the glance-control utility which runs both the glance-api and glance-registry services:

glance-control all start

Once both services are running, you can now use the glance tool to register new images in Glance.

glance add name="My Image" < /path/to/my/image

With an image registered, you can now configure your IAAS provider to use Glance as its image service and begin spinning up instances from your newly registered images.
