Member-only story
Docker has revolutionized the way we build and deploy applications. It allows us to package our application along with its dependencies into a single, lightweight container that can be run anywhere. In this blog post, we will walk you through the process of creating your own Docker container that hosts a web server. We will cover the necessary files, what should be in each file, how to include additional operating system packages, and how to remove default commands that you might not want included.
