Add support for AKS ManagedCluster API version 2026-05-01 and Ingress Gateway API enhancements

Issue

The latest AKS ManagedCluster REST API (2026-05-01) introduces enhancements under ManagedClusterIngressProfile, including support for configuring Web App Routing using Istio based Gateway API

{
  "properties": {
    "ingressProfile": {
      "gatewayAPI": {
        "installation": "Standard"
      }
        ]
      }
    }
  }
}

Currently, Pulumi Azure Native does not appear to support the latest AKS ManagedCluster API version and the corresponding ManagedClusterIngressProfile models.

Background and Impact

Azure AKS is moving away from the nginx based ingress approach, and are undergoing changes with deprecation timelines approaching (November 2026). The latest AKS ManagedCluster REST API (2026-05-01) introduced support for istio based ingress. We are prioritising migration towards Gateway API / Istio-based ingress architecture and need to adopt the latest AKS Gateway API capabilities. The current Pulumi Azure Native support does not expose the required AKS API version and blocks adoption of these features through infrastructure-as-code. This is becoming a priority for production AKS environments that need to adopt the newer Gateway API architecture before upcoming AKS ingress deprecations.

Without support for the latest AKS API version, users are forced to:

• Manage AKS ingress configuration outside Pulumi.
• Delay migration towards Gateway API and Istio-based ingress solutions.

Request

Could you please:

1. Add support for AKS ManagedCluster API version 2026-05-01 or latest in Pulumi Azure Native.
2. Rebuild the generated AKS ManagedCluster resources to use the 2026-05-01 or latest API version by default.

Thank you for reviewing this request.
