source code 

Build a sort key to find the latest available Docker image.

To find one source collection for a Docker image referenced by name or image id, the API server looks for a link with the most recent `image_timestamp` property; then the most recent `created_at` timestamp. This method generates a sort key for Docker metadata links to sort them from least to most preferred.

list_images_in_arv(api_client, num_retries, image_name=None, image_tag=None)

source code 

List all Docker images known to the api_client with image_name and image_tag. If no image_name is given, defaults to listing all Docker images.

Returns a list of tuples representing matching Docker images, sorted in preference order (i.e. the first collection in the list is the one that the API server would use). Each tuple is a (collection_uuid, collection_info) pair, where collection_info is a dict with fields "dockerhash", "repo", "tag", and "timestamp".
