Docker is everywhere and yet it can be incredibly intimidating to engineers who are new to it. In this short video, I attempt to dispel some of the magic around Docker in an effort to get folks comfortable working with Dockerfiles and Docker concepts in general.
Instead of pulling down a ready-made image from Docker Hub, I start with a basic alpine image and build up the necessary software and configuration to run the application. Making a Docker image this way—from “scratch”—hopefully illuminates how Docker works behind the scenes and provides insight into issues folks may encounter at their work or in other projects.
