Oftentimes `attach` doesn't find the container.

[CharlieIGG]

$ plis start web && plis attach web
docker-compose up -d web
back-end-3_postgres_1 is up-to-date
Creating back-end-3_web_1 ... done
No container running for service web

however

$ docker ps

I have other projects with pretty much the same docker-compose.yml where this DOES work, so I'm unsure of why it doesn't work in some others...
