Creating and hosting your own rpm packages and yum repo

This tutorial provides a comprehensive guide on creating RPM packages and setting up a YUM repository for Red Hat-based Linux distributions such as Fedora, CentOS, and Rocky Linux. It begins with the creation of a simple "Hello World" program and progresses to building an RPM package using rpmbuild. The guide further explains how to establish a YUM repository, import PGP keys for signing packages, and configure the system to access the repository for package installation. The tutorial emphasizes the use of Earthly to streamline the build process and offers a complete example on GitHub, allowing users to execute all steps in a single command. It assumes a CentOS 8 environment but provides instructions for using Docker as an alternative. Additionally, it highlights the importance of securing private keys and offers resources for further exploration of container orchestration and build automation tools.
