OpenYurt: Kubernetes at the Edge

by Shriira Press

OpenYurt is the CNCF platform that extends Kubernetes to edge computing — letting a central cloud control plane manage edge nodes and workloads at many distributed, network-unreliable locations, with edge autonomy (nodes keep working when disconnected) and cloud-edge collaboration, non-intrusively (extending vanilla Kubernetes, no fork). This free book teaches it from the ground up: the edge computing problem and what OpenYurt is, edge computing and Kubernetes-at-the-edge concepts, OpenYurt's architecture (cloud and edge components), edge autonomy (YurtHub and offline operation), cloud-edge networking (the Yurt tunnel and Raven), node pools and workload management (YurtAppSet, YurtAppDaemon), edge traffic and topology (keeping traffic local), edge devices and IoT (managing devices through Kubernetes), deploying and operating OpenYurt, and using it in practice. Ten focused chapters with clear diagrams that make Kubernetes at the edge concrete — central management plus edge autonomy, so each site keeps working and serving locally when disconnected, across retail, manufacturing, telco, and IoT.
