The Past, Present, and Future of Kubernetes on Raspberry Pi

Explore the evolution and potential of Kubernetes on Raspberry Pi in this 34-minute conference talk by Alex Ellis from OpenFaaS Ltd. Dive into the history, current state, and future prospects of running Kubernetes on credit-card sized computers. Learn about the similarities between Apple Silicon, AWS Graviton, and Raspberry Pi, and discover how to add support for these devices to open-source projects. Gain insights into building practical Raspberry Pi clusters, from budget-friendly setups to high-performance configurations. Watch live demonstrations, explore open-source tools, and understand the significance of ARM in data centers. Discover the journey from Docker clusters to k3s, and learn about managed cloud solutions and cross-compilation techniques for ARM architecture.
