Показать описание


In this video I explain what a Dockerfile is and why you'd want to use a Dockerfile.
We'll go through a live example building a custom docker image from a Dockerfile. I show you the basic concepts of image layers, the layer cache and building Dockerfiles.

4:54 "getting an error was intentional" -- brilliant! Why don't so many tutorial creators understand this?

Brilliant tutorial Ryan, thanks so much. You take a unique approach of intentionally showing errors and then fixing them. This is how we learn in the real world: from our mistakes. I "liked, subscribe, and hit that bell." The first time ever!
