Bug found in ./appctl bash?

I'm using Google Translate, sorry for errors

I think I found a bug, or it could be that some mistake of mine caused it

Sorry if I'm reporting in the wrong place

When I run ./appctl bash I get: ERROR: No container found for misago_1

I changed the appctl from:

run_bash () {
docker-compose exec misago bash
}

For:

run_bash () {
docker-compose run misago bash
}

and apparently it worked
