The AKS App Routing add-on's Kubernetes Gateway API implementation — approuting-istio — is generally available. Together with that, the Managed Gateway API installation for AKS is also GA, so the CRDs, the controller stack, and the gateway data plane you need to run Gateway API on AKS are all now first-class, supported features.
As of AKS release v20260428 (April 28, 2026), both managed Gateway API (--enable-gateway-api) and the app routing Istio Gateway API implementation (--enable-app-routing-istio) are generally available on AKS.
You no longer need preview feature flags or the aks-preview extension; the steps later in this post reflect the original preview experience.
We're announcing preview support for the Kubernetes Gateway API in the AKS application routing add-on. This brings a modern, role-oriented traffic management model to AKS — and establishes a clear migration path ahead of the upcoming Ingress-NGINX retirement.
