Request: Support for Proxy Protocol

[mikker]

I run my Kamal hosted app behind a load balancer. Previously, to preserve the user's original IP address, I set up Traefik to support Proxy Protocol which Digital Ocean also supports.

Is this something that's on the planning board for kamal-proxy? Or is the suggested remedy to put traefik in between again?

Looking for a similar feature.

Getting the improper IP in the application logs (outer most proxy).

I was able to configure in the past as found here: basecamp/kamal#576 (comment)

I was able to configure this issue away at the application level. I'd much rather manage it at the proxy, but this will move me forward.

We don't have Proxy Protocol support at the moment, but I'll look into it.

Kamal Proxy does allow populating/forwarding X-Forwarded-For, which is another common way to pass through the original IP. Slightly different approach, but can often be a good alternative.

I agree send-proxy would be really helpful. We run haproxy as our load balancers so routing via TCP through to the Kamal proxy hosts without losing IP information would be great.
