Intelligently Packing OS in Container Images - Lessons from CoreOS

Explore the innovative approach to containerizing operating systems in this DevConf.CZ 2023 conference talk. Delve into the world of cloud-native applications and discover how CoreOS is revolutionizing OS image customization through container images. Learn about the implementation of CoreOS layering, which allows for selecting, modifying, and deploying OS images directly to nodes without local hysteresis. Uncover the behind-the-scenes process of packing an entire OS, including the kernel, into a container image while optimizing delta updates. Examine the data science techniques used by rpm-ostree to solve the multi-objective bin packing problem, resulting in significant space savings for Fedora CoreOS upgrades. Gain valuable insights from real-world experiences and discover how to streamline your own update processes in this informative 16-minute presentation by speaker Rishabh Saini.
