docs: replace Ingress NGINX with Gateway API (Envoy Gateway)#5160
Conversation
Ingress NGINX is being retired (March 2026). Update Kubernetes Kit docs to use the Gateway API with Envoy Gateway, which provides built-in session persistence and portable HTTP header manipulation, replacing insecure NGINX-specific configuration snippets. Prerequisite: kubernetes-kit needs to support request header-based version detection (instead of cookie-based) before merging. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Testing locally, I had to set weight: 1, otherwise all requests where redirected to v2.

Same here; to be able to see the notifications weight needs to be 1

A workaround to make ClusterSupport work is to add sessionName: INGRESSCOOKIE to sessionPersistence configuration of HTTPRoute descriptors

This PR is a draft because Kubernetes Kit needs to be updated to detect new application versions via the
X-AppUpdaterequest header (set by the Gateway APIRequestHeaderModifierfilter) instead of relying on NGINX-specific cookie mechanisms.Test plan
