How to set up Nginx Ingress for Load Balancers with Proxy Protocol Support

For anyone using Helm, you can replace steps 1, 2 and 3 (above) with the following …

# nginx-ingress-controller-config.yaml
controller:
  config:
    use-forwarded-headers: "true"
    compute-full-forwarded-for: "true"
    use-proxy-protocol: "true"

helm install --namespace ingress-nginx --name nginx-ingress stable/nginx-ingress -f nginx-ingress-controller-config.yaml

BTW … there’s an issue with proxy protocol and the jet stack cert-manager.

See https://github.com/jetstack/cert-manager/issues/466

My only workaround is to temporarily disable proxy protocol on the load balancer (and nginx ingress config map) allowing the certificate to be issued.

kubectl edit configmap -n ingress-nginx nginx-ingress-controller
#  use-proxy-protocol: "true"
