docker-compose integration not working in pycharm

Question

I've set up docker-compose as a remote interpreter in pycharm using the instructions found here.

The docker-compose build works fine, but when trying to run a test using this interpreter I get the following error:

Testing started at 12:13 AM ...
docker-compose://[/home/melchoir55/gitrepos/python_rest/docker-compose.yml]:python_rest/python -u /opt/.pycharm_helpers/pycharm/_jb_unittest_runner.py --path /opt/project/tests

[8964] Failed to execute script docker-compose

Process finished with exit code 255

I haven't done much to the system other than installing pycharm, docker, docker-compose, and adding my user to the docker group for permissions. Does anyone know what docker-compose is complaining about here via pycharm?

I did note that there seem to be some env vars which I don't have set related to these certificates, but it isn't clear to me what they should be set to, if I were to set them.

Update:

For reference I am running pycharm in Ubuntu within a virtualbox machine.

Turns out using the TCP socket API URL was the way to go. I passed the unix socket to the TCP socket, and it worked.

This is the string i use in the Engine API URL unix:///var/run/docker.sock.

Found the answer here.
