How to setup LinkStack with ssl through reverse_proxy with caddy

[giacomolanzi]

Hello,
I am having trouble setting up LinkStack on docker alongside with Caddy for reverse proxy.

Here is my yml:

services:
  caddy:
    image: caddy:latest
    restart: unless-stopped
    container_name: caddy
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - caddy_data:/data
      - ${DATA_FOLDER}/caddy_config:/config
      - ${DATA_FOLDER}/caddy_config/Caddyfile:/etc/caddy/Caddyfile

  n8n:
    image: docker.n8n.io/n8nio/n8n
    container_name: n8n
    restart: always
    environment:
      - N8N_HOST=${N8N_SUBDOMAIN}.${DOMAIN_NAME}
      - N8N_PORT=5678
      - N8N_PROTOCOL=https
      - NODE_ENV=production
      - WEBHOOK_URL=https://${N8N_SUBDOMAIN}.${DOMAIN_NAME}/
      - GENERIC_TIMEZONE=${GENERIC_TIMEZONE}
      - N8N_LOG_OUTPUT=console
      - N8N_LOG_LEVEL=debug
    volumes:
      - n8n_data:/home/node/.n8n
      - ${DATA_FOLDER}/local_files:/files

  portainer:
    image: portainer/portainer-ce:latest
    container_name: portainer
    ports:
      - "9000:9000"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - portainer_data:/data
    restart: unless-stopped

  linkstack:
    container_name: linkstack
    hostname: linkstack
    environment:
      - HTTP_SERVER_NAME=links.***.it
      - HTTPS_SERVER_NAME=links.***.it
      - TZ=Europe/Rome
      - PHP_MEMORY_LIMIT=512M
      - UPLOAD_MAX_FILESIZE=8M
    ports:
      - "8190:443"
    restart: unless-stopped
    volumes:
      - linkstack:/htdocs
    image: linkstackorg/linkstack:latest

volumes:
  caddy_data:
    external: true
  n8n_data:
    external: true
  portainer_data:
  linkstack:
    external: true

To be noted: I edited the HTTP_SERVER_NAME and HTTPS_SERVER_NAME using the third level domain I would like to use to navigate to LinkStack.
Since ports 80/443 are used by caddy, I assigned 8190:443.

Here is my Caddy Config section related to LinkStack:

links.***.it {
  reverse_proxy linkstack:8190 {
    transport http {
      tls_insecure_skip_verify
    }
  }
}

What I am doing wrong?

You exported the port 8190 externally.
Since all of these containers are in the same docker compose file, they all share the same network and you can access the port of the container directly:

links.***.it {
  reverse_proxy linkstack:443{
    transport http {
      tls_insecure_skip_verify
    }
  }
}

You don't even need to export ports since you're using caddy.

@giacomolanzi did you get it working? I am having a similar issue.
