how to use Coolify's reverse proxy for a baremetal application?

[itsyigid]

Hello everyone,

I apologize if this question has been asked before. I've searched through previous discussions and the web but haven't found a helpful solution.

I recently installed Syncthing on bare metal to address some performance issues. I bound it to localhost:3003. I also tried configuring "Dynamic Configurations" under "Server > Proxy" but this only resulted in losing access to the proxy altogether.

Below are the specific configurations I attempted:

1

http:
  routers:
    syncthing:
      rule: "Host(`sync.example.org`)"
      service: syncthing
      entryPoints:
        - websecure
      tls: {}
      middlewares:
        - secHeaders@file

  services:
    syncthing:
      loadBalancer:
        servers:
          - url: "http://localhost:3003"

http:
  routers:
    syncthing:
      rule: "Host(`sync.example.org`)"
      service: syncthing
      entryPoints:
        - websecure
      tls:
        certResolver: coolify

  services:
    syncthing:
      loadBalancer:
        servers:
          - url: "http://localhost:3003"

http:
  routers:
    syncthing:
      rule: "Host(`sync.example.org`)"
      service: syncthing
      tls: {}

  services:
    syncthing:
      loadBalancer:
        servers:
          - url: "http://localhost:3003"

Thanks in advance.

http:
  middlewares:
    redirect-to-https:
      redirectscheme:
        scheme: https
    gzip:
      compress: true
  routers:
    syncthing-http:
      middlewares:
        - redirect-to-https
      entryPoints:
        - http
      service: syncthing
      rule: Host(`sync.example.org`)
    syncthing-https:
      entryPoints:
        - https
      service: syncthing
      rule: Host(`sync.example.org`)
      tls:
        certresolver: letsencrypt
  services:
    syncthing:
      loadBalancer:
        servers:
          -
            url: 'http://host.docker.internal:3003'

this assumes you have certs installed or are not behind a dns proxy
if you are you would have to remove the https entries

With this I was able to get Traefik automatically register a new cert from Let's Encrypt, however I get "Bad Gateway" when I navigate to sync.example.org. In addition to that, I also lose access to other Coolify-managed domains on the same host ({git,dav}.example.org)

[djsisson]

is it actually bound to port 3003 on host

and this should have no effect on any other services

it sounds like you have some other issue tbh

Edit: editing Syncthing's configuration to listen on 0.0.0.0:PORT instead of localhost:PORT was the fix to "Bad Gateway", however tinkering around with dynamic conf. did made me lose access to other Coolify-installed applications.

No, it's not actually on 3003, and definitely not on example.org 😄 However, I translate every details correctly while configuring the actual thing. Here's where I type in the configuration:
