I'm very much a novice with docker, but I believe these are called stacks. Stacks are 'doable' in portainer, but I get hung up with the config json. It's probably more simple than I'm thinking it is, but again, I'm an old-head in small business ownership who grew up with VM's and the whole docker thing is something I've struggled wrapping my head around because I'm not in it every day like I used to be.
