I do not see image being returned as part of the RESTful GET method response. Where is the image?

Please help!

Steve, please read the spec at http://glance.openstack.org/glanceapi.html. :)

GET /images

returns a JSON structure describing the public images.

GET /images/<ID>

returns the image files themselves, with image metadata in the HTTP headers.

Cheers!

Jay,

The API is inconsistent IMHO.

GET /images/<ID>

should return the image description in JSON format.

GET /images/<ID>/data

should return the actual data.

Hi Marek,

I appreciate your comments, and perhaps we can look at changing this in a 2.0 API. However, I would like to note that Glance's API is virtually identical to that of Swift. We took our cues for using HEAD /images/<ID> and GET /images/<ID> directly from there...

Can I ask, what client/programming language are you using?

Cheers!
