Navigating Kairos: Immutable Operating Systems with a Cloud Native Twist

Exploring Kairos: Turning Linux Distributions into Immutable Operating Systems In this episode, we dive into the Kairos project, a CNCF initiative aimed at converting any Linux distribution into an immutable operating system. Hosts David and Laura chat with Mauro and Dimitris, maintainers of Kairos, discussing the motivations, technical aspects, and unique features of the project. Listeners get an inside look at the challenges and solutions involved in creating an immutable OS, the project's community, and its intriguing name origin. Whether you're a home lab enthusiast or an enterprise developer, this episode offers valuable insights into Linux immutability, system management, and future trends.

Flatcar Linux: A Modern OS for the Always-On Infrastructure

In this episode, we dive deep into Flatcar Linux, an immutable Linux distribution designed for always-on infrastructures. The discussion covers the architecture and features of Flatcar, including its self-updating capabilities and minimal attack surface. We explore the use of Ignition for provisioning, the role of Systemd and its extensions, and the detailed update process via an update server. The Flatcar maintainers also highlight the benefits of full-disk encryption, node-level metrics, and operational insights available through tools like Nebraska and Node exporter. Guest speakers include Flatcar maintainers and engineers from Microsoft, who share their experiences and insights on managing and maintaining Flatcar at scale.

Platform Engineering: Asking "Why"? with Evelyn Osman
