Docker Compose Volumes Basics

Question

I understand if it was:

volumes:
  - /home/{user}/config:/config

You would find it in the local user directory -> /home/{user}/config

But when declaring;

volumes:
  - ./:/config

Where is "./"?

Answer 1

. in Unix generally means "the current directory", and in the case of Compose it's the directory containing the (first) docker-compose.yml file .
