There are two nginx ingress controllers for Kubernetes. The Kubernetes official one ingress-nginx, and the F5 nginx official one nginx-ingress-controller. Currently we only have support docs for ingress-nginx.

The nginx documentation may also be useful for crafting advanced snippets to use with annotations even though it's not specific to Kubernetes.

NGINX Ingress Controller (ingress-nginx)

If you use NGINX Ingress Controller (ingress-nginx) you can protect an ingress with the following annotations. The example assumes that the public domain Authelia is served on is https://auth.example.com and there is a Kubernetes service with the name authelia in the default namespace with TCP port 80 configured to route to the Authelia HTTP port and that your cluster is configured with the default DNS domain name of cluster.local.

Ingress Annotations

annotations:
  nginx.ingress.kubernetes.io/auth-response-headers: Remote-User,Remote-Name,Remote-Groups,Remote-Email
  nginx.ingress.kubernetes.io/auth-signin: https://auth.example.com
  nginx.ingress.kubernetes.io/auth-snippet: |
    proxy_set_header X-Forwarded-Method $request_method;    
  nginx.ingress.kubernetes.io/auth-url: http://authelia.default.svc.cluster.local/api/verify
