So i have a vm hosted on my proxmox server with docker and nginx proxy manager, it can reverse proxy any container on the same network “bridge” without any problems…

However, i have other vms on proxmox “non docker” that i eant to reverse proxy to it but I couldn’t do it… I tried using (network_mode: host) and (network: external) But it doesn’t seem to work, whenever i inspect docker network it always says that npm is running on bridge network…

Tldr I need containerized npm to reverse proxy other “non docker” proxmox vms

    I suggest creating a custom docker bridge network on which you put all your other docker containers that you want to give access to the local network. There are other reasons a custom bridge is preferred, but that’s a different subject.

    Here is the terminal command that will create a custom docker bridge network named reverse_proxy:

    docker network create --opt "encrypted" --scope "local" --driver "bridge" --subnet "172.27.2.0/24" --gateway "172.27.2.254" --attachable "reverse_proxy"
    

    Here’s the NXPM docker-compose.yml I’m using that works for this purpose:

    version: '3'
    
    networks:
      reverse_proxy:
        external: true
    
    services:
      app:
        image: 'jlesage/nginx-proxy-manager'
        container_name: 'nxpm'
        restart: unless-stopped
        networks:
          - reverse_proxy
        ports:
          - '443:443' # https
          - '80:80'   # http
          - '81:81'   # npxm webui
        volumes:
          - /opt/docker/appdata/nxpm/data:/data
          - /opt/docker/appdata/nxpm/certs:/etc/letsencrypt
    

    Note the two networks: sections, one outside of and one inside the nxpm service stanza.

    Once this container is up and running, you should be able to route to any network service on the local area network connected to your docker host by creating a host redirect in the nxpm webui that points to that services lan.ip:port.

      modifed my yml file to match yours

      version: '3.8'

      services:

      networks:

      reverse_proxy:

      external: true

      app:

      image: 'jc21/nginx-proxy-manager:latest'

      restart: unless-stopped

      networks:

      - reverse_proxy

      ports:

      # These ports are in format :

      - '80:80' # Public HTTP Port

      - '443:443' # Public HTTPS Port

      - '81:81' # Admin Web Port

      # Add any other Stream port you want to expose

      # - '21:21' # FTP

      # Uncomment the next line if you uncomment anything in the section

      # environment:

      # Uncomment this if you want to change the location of

      # the SQLite DB file within the container

      # DB_SQLITE_FILE: "/data/database.sqlite"

      # Uncomment this if IPv6 is not enabled on your host

      # DISABLE_IPV6: 'true'

      volumes:

      - ./data:/data

      - ./letsencrypt:/etc/letsencrypt

      but when running docer compose up i get this error

      validating /home/ubuntu/nginx-npm/docker-compose.yml: networks.app Additional property restart is not allowed
