imgsync will download sync images from several distribution repositories and send them to an OpenStack Image service (Glance).
OpenStack Glance Image Synchronization tool
This application will download images from the official distribution repository, and upload them to OpenStack Glance. It is possible to define custom properties and prefixes for all the synced images.

Install it via PyPI:
pip install imgsync
Or install it from the repo:
git clone https://github.com/alvarolopez/imgsync pip install imgsync
adjust it your your needs. Take into account the following:
You need to configure your OpenStack Keystone authentication under the
[keystone_auth]section. The user should be able to publicize images in your glance deployment (check your policy file).
You can define a prefix to be used for all the distribution names with the
Additionally you can add some custom image properties, using the
propertiesoption, that can be repeated multiple times for multiple properties.
The list of images to be downloaded is configured via the
CentOS distributions define additional options to allow the download of all the published images, or just the latest one. This is configured in the
[centos6]sections. This is not possible for Debian and Ubuntu.
imgsync sets a property
source=imgsync to all the images that donwloaded
and synced. This way we can identify if an image is uploaded into glance by us
or by anyone else. This property is hardcoded and cannot be reconfigured or
replaced by something else. Other properties set by
imgsync are are stored with the
Nevertheless, it is also possible to define additional properties in the form
"key=value" via the
properties option in the configuration file (you can
specify this option several times).
Therefore, it is important that you configure glance to enable the proper
policy protection rules
so that only the configured user is able to write those properties (i.e. at
imgsync.sha256). Moreover, you need to
configure nova to exclude those properties when nova creates and uploads an
snapshot to glance, via the
non_inheritable_image_properties option in your
/etc/nova/nova.conf configuration file (again, at least add
