Frequently Asked Questions

What is an ingress controller?

A component that implements Ingress rules by configuring a proxy or load balancer to route external requests to services in the cluster.

Ingress or Gateway API?

Gateway API is the newer, more expressive Kubernetes API for traffic routing and many controllers now implement it. Ingress remains widely used.

What happened to ingress-nginx?

The Kubernetes project announced the retirement of the community ingress-nginx controller in November 2025, and its repository was archived on 24 March 2026. F5 NGINX Ingress Controller is a separate, vendor-supported project.

Which entries are archived?

The Avi Kubernetes Operator repository now sits in vmware-archive, so its card is marked.

What changed on this page?

All 17 original entries are kept. Emissary-ingress, the Gateway API, Envoy Gateway and the ingress-nginx note were added.

Which Gateway API features became Standard in v1.5?

Gateway API v1.5.0, released on 27 February 2026, moved six features to the Standard channel: ListenerSet, TLSRoute, the HTTPRoute CORS filter, client certificate validation, certificate selection for Gateway TLS origination, and ReferenceGrant.
