[HOWTO] access to all your dockers webGUIs

your easy and first approach is to use portainer to acces to your dockers webGUI, only need to click on the desired port on container list.

but first time portainer try to open on http://0.0.0.0:yourclickedport that obviosly do not work, so you need to first configure your NAS Ip on:

settings -> enviroments -> local:

after this, the click works as expected and open the desired webGUI.

a more visual and good option is to use heimdall to access your dockers webGUI.

you only need to install heimdall docker and configure it.

more info about heimdall: https://heimdall.site/

and https://hub.docker.com/r/linuxserver/heimdall/

my heimdall.yaml file for example is:

version: "2.1"
networks:
  default:
    external:
      name: my-net  # I use allways my-net in all my bridge dockers, so swag can resolve dockers name.
services:
  heimdall:
    image: linuxserver/heimdall
    container_name: heimdall
    environment:
      - PUID=1001  # my dockers user, created on OMV webGUI and properly assigned to read&write on desired folders
      - PGID=1000  # my docker group, created on OMV webGUI and properly assigned to desired users (users,dockers)
      - TZ=Europe/Madrid
    volumes:
      - /srv/dev-disk-by-uuid-d59044e2-5d51-4ecf-b07a-d0ccd526f123/Datos/Dockers/heimdall:/config
    ports:
      - 4443:443
      - 8080:80 #optional
    restart: unless-stopped

of course you can access your heimdall landing page outside your LAN ( from internet), to do it you need 2 more dockers:

duckdns docker & swag docker to properly redirect to your own domain.

but that are part of other guides.
