Description

Feature Request:

Azure Shared Image Galleries went GA in June 2019, and it seems like a natural extension of the cloud profile functionality to allow them to be used as the source of a cloud profile image in the "Image Type" dropdown:

The configuration fields would need to include the Gallery Name, Image Definition name and Image Version, although it would be useful to be able to specify something like "latest" for the Image Version to avoid needing to keep modifying it when publishing a new version of an image definition.

As a workaround we've had to write some scripts to spin up our own long-lived virtual machines in Azure from the image gallery images every time we publish new image versions (which is quite frequently), and automate adding them as regular agents in a separate agent pool, but we'd much rather use cloud profiles to build ephemeral agents on demand.

Environment
