Alpine Linux Package Building with abuild and Docker

Creating custom packages for lightweight Alpine Linux deployments does not have to be complicated. By containerizing your build environment, you can safely compile, package, and sign software without cluttering your local system. This text-based course guides you from absolute beginner to confidently configuring a secure Alpine packaging pipeline. You will learn how to leverage Docker to isolate your build tools, generate cryptographic keys, and compile custom packages ready for distribution. What you will learn: Understand Alpine Linux package management fundamentals and the apk ecosystem; Configure a clean packaging environment using Alpine Docker containers; Install and initialize the abuild SDK and its essential dependencies; Generate and manage cryptographic public/private keys to sign your packages securely; Create and edit APKBUILD files to define package metadata and build instructions; Apply modern container security practices to keep your private signing keys safe. The course begins with foundational concepts of package managers and containerization before moving step-by-step through environment configuration, key generation, and running your first containerized build. Designed for system administrators, DevOps engineers, and developers new to Alpine packaging, this course requires no prior packaging experience.
