Contour: Envoy-Powered Ingress for Kubernetes
Shriira Press
The front door to your cluster. Route, secure, and manage external traffic with Contour — an Envoy-based Kubernetes ingress controller.
Welcome to Contour: Envoy-Powered Ingress for Kubernetes.
Contour is an ingress controller for Kubernetes — a control plane that programs the high-performance Envoy proxy to route external traffic to services inside your cluster. This free book teaches it from the ground up: the ingress problem and what Contour is, the Kubernetes Ingress resource and its limitations, Contour's architecture (the control-plane/data-plane split, Contour configuring Envoy via xDS), getting traffic in (load balancers, the request path), HTTPProxy (Contour's richer, validated, delegation-capable resource), routing and load balancing (host/path/header conditions, strategies, health checks), TLS and secure traffic (termination, cert-manager, mTLS), advanced traffic management (canary traffic splitting, timeouts, retries, rate limiting), the Gateway API and its role-oriented model, and operating Contour in practice. Ten focused chapters with clear diagrams that demystify how external traffic gets into a Kubernetes cluster — routed, secured, and managed — through an Envoy-powered ingress gateway.
