In this course, you will learn how packaging software works in Alpine Linux, the most popular Docker Linux distribution.

You’ll first learn the basics: what is Alpine Linux and what are its advantages over other distributions, especially in a Docker environment? Next, you’ll cover the basics of packaging software: what are apk and APKBUILD, where should files be installed, and how can we create basic APKBUILDs and submit them for inclusion in Alpine Linux official repositories? You’ll also learn what makes an Alpine Linux package low or high quality. Finally, you’ll explore APKBUILDs for different programming languages and finish by creating your own private Alpine Linux repository with complex subpackages. 

By the end of the course, you will be able to create APKBUILDs which easily pass Alpine’s quality assurance. Overall, this course will increase your understanding of Alpine Linux and Linux in general and help you improve your DevOps skills.
