Let's review some of the basic concepts before you start to put them into practice. This guide assumes you are familiar with Docker and its build environment. Refreshing basic concepts about Docker images and Dockerfiles To do that, I have provided you with a GitHub repository that contains all the files you need, to follow the tips and tricks shown in this post. Then, I will walk you through some practical examples, to improve the build time, the size, and the security of a Docker image. First, I will briefly explain some basic concepts that you need to refresh before examining specific cases. In this tutorial, I will go over these lessons learned, describing some of the best practices and common pitfalls that you are likely to encounter when developing Dockerfiles, by applying them on practical examples.
