Deploying OpenStack

Installation

If you are on Ubuntu 11.04 or later, Glance can be installed with a simple apt-get:

$ sudo apt-get install glance python-glance-doc

Note

Glance requires a large number of dependencies.

Once installed, it needs to be started with the glance-control utility.

$ sudo glance-control all start

Glance is now ready for uploading and querying of virtual disk images. The glance index command shows all virtual disk images currently in Glance.

$ glance index
No public images found.

As you can see from the example above, Glance is currently empty. Let's put a image into it. The glance-upload command puts an image record into the glance-registry and stores the data file in the image store. It requires a the disk format and container format as a minimum set of arguments. In this example, the virtual disk is formatted as an AMI from the Ubuntu Enterprise Cloud image repository.

$ glance-upload natty-server-uec-amd64.img natty-uec --disk-format ami \
 --container-format ami
Stored image. Got identifier: {u'checksum': u'b420e097baf54cd32af5970b3f0cb93b',

Now that an image has been uploaded, Glance should show it via the glance index command. ...
