Kubernetes Gateway API is emerging as a more expressive and flexible alternative to the traditional Ingress resource for managing external traffic. This post walks through setting up domain-based routing to applications, a common requirement for production environments. It covers the core concepts of Gateway, GatewayClass, and HTTPRoute, and shows how to bind a domain name to a specific service. For teams already using or considering Gateway API, this provides a clear starting point. The approach simplifies multi-tenant routing and offers better separation of concerns compared to Ingress controllers. As the ecosystem matures, understanding these patterns becomes essential for scalable Kubernetes networking.
A practical guide on configuring domain-based access in Kubernetes using Gateway API, highlighting key steps and benefits over Ingress.
