How to operate a running Compose stack — ps, logs, exec

The stack is up and you need its status, one service's logs, or a command inside the database service.

docker compose ps                               # status of every service
docker compose logs -f web                      # follow one service
docker compose exec db psql -U postgres         # run a command in the db service
