# Use Diskimage Builder in Nodepool¶

To ensure identical test environments in different clouds, use Diskimage Builder to create images which are then uploaded to each cloud used by Nodepool.

## Problem Description¶

Each cloud provider in use by Nodepool supplies different images which can cause tests to perform differently.

## Proposed Change¶

Rather than try to correct the delta in each provider, create an image locally that can be used in any provider and upload it to Glance.

Because it is difficult to use glance in all of its deployment variations, move much of the cloud-interaction logic into the “shade” library and use that to perform the uploads.

### Alternatives¶

Keep playing catch-up whenever clouds update their images.
