Manually copying the VM images to the distributed repositories is labour intensive and prone to error. To reduce the management overhead and the number of errors associated with distributing VM images, we have developed an image distribution service called Glint. Glint is being developed as an OpenStack service, adhering to OpenStack's development and deployment architecture and accessible through modifications to the Horizon dashboard. The service uses keystone authentication and leverages the glance API to control image distribution across the network. Glint provides functions to allow users to identify remote repositories and to distribute images to those repositories. Glint maintains a list of remote repositories for each tenant and, for each user of the remote repository, the user's credentials. Having defined both the repositories and the required credentials, the user can display a matrix of repositories and images, and use it to control the distribution of images. Within the cells of the image distribution matrix, check-boxes indicate the presence (checked) or absence (unchecked) of images within repositories. Users can toggle one or more check-boxes and press the "Save" key to effect image distribution. A separate thread is created for each selection and all operations are performed in parallel. This presentation, will discuss the experience of HEP users over the past several months, highlighting the user interfaces, processing internals, and future developments.
