docker_dna - create a Dockerfile from a Docker hub image's family tree
Docker DNA gives you the convenience of referencing another developer’s Dockerfile without the risk. Instead of your image being directly generated from someone else’s directives, it assembles a new Dockerfile by tracing the ancestors of a given repository image and concatenating the results.
The result is a Dockerfile that you are in total control of and whose source is in a single place (not spread across repos/hub pages).
