Explore edge computing using K3s on Raspberry Pi in this informative conference talk. Learn how to deploy a production-grade, highly available 3-node K3s cluster, capture configuration as code, implement GitOps-driven changes, and manage automatic updates for both the cluster and operating system through the Kubernetes API. Discover the design, implementation, and trade-offs of this edge architecture, including the use of Raspberry Pi 4 and K3s, a lightweight single binary Kubernetes distribution. Gain insights into core project goals, image creation, network joining, OS bootstrapping, and system upgrade controller architecture. Understand the essential components and future possibilities for edge computing deployments using this innovative approach.
