This article discusses the archiving of ingress-nginx, which will no longer receive maintenance starting in 2026. It outlines two main migration paths for Kubernetes users: moving to Cilium Ingress for a quick transition or adopting the Gateway API for enhanced traffic management.

The blog post introduces the Gateway API Inference Extension, which enhances the functionality of the Gateway API in Kubernetes. This extension aims to provide improved traffic management and routing capabilities for applications, facilitating better service integration and deployment strategies. The article outlines its key features and potential use cases for developers and system architects.

DigitalOcean has introduced the Kubernetes Gateway API as a managed service in its DOKS clusters, offering advanced traffic management features that overcome the limitations of the traditional Ingress. This new solution, powered by Cilium's eBPF technology, improves performance, routing capabilities, and supports multi-tenant environments at no additional cost. It separates infrastructure and application concerns, allowing for clearer responsibilities among cluster operators and application developers.

Learn how to manage north/south traffic in Kubernetes using the Gateway API, which offers a flexible alternative to Ingress Controllers. The article walks through the process of setting up a Gateway, configuring a GatewayClass, and creating an HTTPRoute to route traffic to a backend service. By following the provided steps, readers can successfully implement their own Kubernetes Gateway API configuration.

Kubernetes traffic management is challenging due to the complexity of modern applications and the limitations of traditional tools like Ingress. The Gateway API offers a standardized, Kubernetes-native framework that improves traffic management by enabling advanced routing, load balancing, and security while simplifying configurations across clusters. This solution addresses the operational difficulties associated with managing multiple services in dynamic environments.

Kubernetes traffic management is evolving with the introduction of the Gateway API, which addresses the limitations of traditional Ingress controllers by offering standardization, role-based architecture, and richer features. The Calico Ingress Gateway, powered by Envoy, provides a robust implementation of this new standard, allowing for secure application deployments with automated TLS management. This blog details the setup process and key configurations needed to leverage these advancements in a Kubernetes environment.

The Kubernetes Gateway API v1.3 introduces several enhancements aimed at improving service networking, including support for route imports and exports, better traffic management, and increased extensibility for developers. These updates facilitate more flexible and efficient interactions between services in Kubernetes environments, addressing common networking challenges.

The Gateway API Inference Extension project addresses the unique challenges of running AI inference workloads on Kubernetes by introducing two new Custom Resource Definitions (CRDs), InferenceModel and InferencePool. This extension enhances request routing and load balancing through an intelligent endpoint selection process that utilizes real-time metrics from LLMs, optimizing GPU usage and improving system performance.
