Installing Discourse With Caddy (Docker Compose) (hetzner Cloud)

Help
1

1. The problem I’m having:

I am experiencing an error when trying to connect to my second site that is linked to /var/discourse/shared/standalone/nginx.http.sock (Discourse). The error message states that the file unix//var/discourse/shared/standalone/nginx.http.sock does not exist, although it actually exists with the correct file permissions.

2. Error messages and/or full log output:

3. Caddy version:

v2.6.4

4. How I installed and ran Caddy:

Installed it for the first time using the official docker image through N8N official installation, Source / (Hetzner)

a. System environment:

### System Environment ###

OS: Ubuntu 22.04.2 LTS
Kernel: Linux 5.15.0-73-generic (aarch64)
Systemd: Running
Docker Client: 23.0.3 (API version: 1.42)
Docker Server: 24.0.2 (API version: 1.43)

b. Command:

cd n8n-docker-caddy
docker compose up --build
sudo nano /root/n8n-docker-caddy/caddy_config/Caddyfile
sudo nano /root/n8n-docker-caddy/docker-compose.yml

c. Docker Compose file:

version: "3.7"

services:
  caddy:
    image: caddy:latest
    restart: unless-stopped
    ports:
      - "80:80"
      - "443:443"

      - ${DATA_FOLDER}/caddy_config:/config
      - ${DATA_FOLDER}/caddy_config/Caddyfile:/etc/caddy/Caddyfile

  n8n:
    image: n8nio/n8n
    restart: always
    ports:

      - ${DATA_FOLDER}/.n8n:/home/node/.n8n

volumes:
  caddy_data:
    external: true
  caddy_config:

d. My complete Caddy config:

{
    # Global options go here
}

slave.iraki.net {
    reverse_proxy n8n-docker-caddy-n8n-1:5678 {
        flush_interval -1
    }
}

forum.iraki.net {
    reverse_proxy / unix//var/discourse/shared/standalone/nginx.http.sock 
}

Vaildate results:

You can probably simply do reverse_proxy n8n:5678. You don’t need the full container name, you can use the service name. And you probably don’t need flush_interval -1, Caddy should automatically detect if it’s needed for the given request.

reverse_proxy / will only proxy requests to exactly / and nothing else. Remove that /, it’s probably not what you intended.

Also, I don’t see /var/discourse mounted to Caddy’s container. Are you sure that’s the correct path? Shouldn’t it be unix//sock/standalone/nginx.http.sock, maybe?

You don’t need this line, Caddy only needs UDP for port 443 (HTTP/3) not port 80.

You probably don’t need this either, this is exposing that service to anything which can connect to your server. If you remove it, you can be sure all the traffic went through Caddy first and used HTTPS.
