gRPC Support

[lille-morille]

I was wondering if it would be possible to implement gRPC support for services.

Traefik supports it, but I can't seem to get it to work using Coolify.

+1 on this request, although we can make it work with h2c, we loose the automatic traefik config generation which is a shame.

Hey guys! Did you find a way to use grpc?

+1.

For those seeking an immediate solution: Set the label traefik.http.services.(any_name).loadbalancer.server.scheme=h2c.
https://doc.traefik.io/traefik/user-guides/grpc/

services:
  my_service:
    # ...
    labels:
      - traefik.http.services.my_service_h2c.loadbalancer.server.scheme=h2c

However, if the auto-generated configuration includes traefik.http.router.(ID).service=..., this will stop working.
In that case, you need to make the (any_name) part match the others.

I am using the default configuration of Traefik labels on my server and I am getting HTTP 500 errors from the reverse proxy. I have the following middlewares enabled: gzip, redirect-to-https. How can I configure Traefik to route the traffic via HTTP/2 to my Docker container? I have used h2c scheme on both services (http and https) and it's what has triggered the aforementioned error.
