HTTPRoute
An HTTPRoute is a Kubernetes Gateway API resource defining how HTTP requests are matched and forwarded to backend services through parent gateways.
Kubernetes in Action, Second Edition
An HTTPRoute is a Kubernetes Gateway API resource that defines how HTTP requests are matched and forwarded to backend services through parent gateways.
- How it is used
- Connects HTTP traffic arriving at a Gateway to backend Services using route rules.
- How deep it goes
- Works through a manifest, request matches, weights, filters, status checks, and cross-namespace permissions; does not detail controller internals.
- Examples
- Tests a hostname-based route with kubectl and curl, then demonstrates weighted canary backends and POST-based routing.
- What you can do after
- Build it from scratch with a Gateway API manifest, then test routing and diagnose attachment or reference failures with kubectl.

An HTTPRoute is a Gateway API resource that defines HTTP host, path, and backend routing rules for application traffic.
- How it is used
- Defines application-level HTTP routing while separating route ownership from Gateway and GatewayClass infrastructure management.
- How deep it goes
- Demonstrates hostname, path-prefix, parent-Gateway, backend-Service, and port configuration, then verifies creation with kubectl.
- Examples
- Uses www.example.com with a root PathPrefix to route traffic to the nginx Service on port 8080.
- What you can do after
- Build it from scratch with a v1 manifest, attach it to a Gateway, route a hostname, and verify the resulting resource.
