Best Practices in Docker
As our containers and services grow in size and complexity, it is important to make sure we are keeping true to the best practices when creating our Docker images. This is also true for the applications we run on our Docker images. Later in this chapter, we will look to lint our Dockerfiles and docker-compose.yml files, which will analyze our files for errors and best practices, and this will give you a clearer understanding. In the meantime, let's look into some of the more important best practices to keep in mind when you are creating your Docker images and how your applications should be working with them.
