I recently started using Docker, and with that produced an absolute pile of questions. Scraping through Google and StackOverflow for answers, here is a compilation of what I can remember learning on the first day.

Images and Docker Hub

How do I see the actual docker file on Docker Hub?

Amazingly this isn’t a simple thing.

Docker Hub really just hosts the images, not the actual Dockerfile used to make them (assuming they were made from a Dockerfile). You can get lucky by heading to the page for the desired image on Docker Hub, and often you will find a link to a GitHub hosted Dockerfile.
