I'm trying to understand what you're trying to achieve then. If you spin up the containers using regular docker commands, the containers are visible in Portainer and you can stop/start/restart them. If you launch it using a compose file, you can create a stack in Portainer and place the contents of the compose file in the editor.

The project itself has some nice install instructions. How far did you get with that?
