Can Ingress Proxy be enabled and disabled for individual ports?

Posted December 18, 2019 2.3k views

I know it is possible to enable Proxy protocol for Ingress (also by service annotation): “true”

That works great with Proxy aware services like my web applications running on port 80 (http) and 443 (https)

However, for services like SQL Server running on tcp port 1433, connecting to that service works when proxy protocol is disabled, and doesn’t work when proxy protocol is enabled.

Is there a way to enable and disable Ingress Proxy for individual ports, e.g. to be enabled for ports 80/433 and to be disabled for other tcp ports (e.g. port 1433)?

My only solution now is to have two-ingress-services and two official IP-addresses and that will of course also cost the double a month.

Here is how I setup Ingress using helm chart:

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


    use-forwarded-headers: "true"
    compute-full-forwarded-for: "true"
    use-proxy-protocol: "true"
    annotations: "true" 
        1433: 32496 # Any random port 30000-32767
  1433: "sqlserver/mssql:1433" #namespace/service-name:port

Hi there,

Unfortunately, proxy protocol as far as I’m aware is an all or nothing thing on the DO load balancer’s so if both of your apps can’t use a single configuration, you would need two loadbalancers.

If you are using tcp-services and LB proxy protocol

you can just add :PROXY in your configMap

1433: “sqlserver/mssql:1433:PROXY”

and reboot nginx controller
