Asustor NAS Portainer docker setup and mount

Indeed I started with this description. I used this install guide without any issue when I installed it on a windows machine. On the other hand, when I tried to install it to my NAS via Portainer I couldn't configure it properly. After the container cofig it won't start, just exit immediately with "exit code 1". This is why I'd like to ask for a specific "install guide with portainer".
