Knative: Serverless on Kubernetes

by Shriira Press

Knative brings serverless to Kubernetes: deploy code that autoscales (including to zero when idle), and connect services through events — the cloud-function experience without lock-in, on any cluster. This free book teaches it from the ground up: the serverless model and scale-to-zero, Knative's architecture (Serving, Eventing, the activator, and pluggable networking), Knative Serving's resources (Service, Configuration, Revision, Route), request-driven autoscaling with the Knative Pod Autoscaler, traffic management and progressive delivery (canary, blue-green, instant rollback), Knative Eventing with CloudEvents (sources, brokers, triggers), building event-driven applications, the networking layer (Kourier/Istio), and operating Knative in production. Ten focused chapters with real config and clear diagrams that show how to run serverless workloads — scaling to zero and wired with events — on portable Kubernetes.
