$ docker -v

Docker version 18.06.0-ce, build 0ffa825

I have some docker-compose file that actually has this string of line:

volumes:

    - .:/sql

And In "." directory I have plenty of directories and files:

$ ls -l

total 32

-rw-r--r--   1 michael  staff   161 Nov  9 13:35 README.ms

drwxr-xr-x  12 michael  staff   384 Nov  9 13:35 backend

-rwxr-xr-x   1 michael  staff  1438 Nov  9 13:35 manage.py

drwxr-xr-x  12 michael  staff   384 Nov 10 13:28 ops

drwxr-xr-x   5 michael  staff   160 Nov  9 13:35 requirements

-rw-r--r--   1 michael  staff    38 Nov  9 13:35 requirements.txt

But when I start this container and go inside, all I see there:

# ls -1 /sql

docker-compose.yml

ops

Pay attention: file docker-compose.yml is even not from this directory. It is from ops/

Who has an idea of the cause?

Figured out the reason.

No matter where you start docker-compose from, it takes "." as a location of docker-compose.yml file. Thus, all you expect to see inside container have to be located within the very same directory where docker-compose.yml resides at.
