Why?

For a socket ain't a udp or tcp port, it's a file, you need to share the socket file from the host into the docker image and then from within the docker access that socket file.

Check volumes in the docker-compose documentation.

Configure docker is generally thought as off topic as it's nothing to do
with PHP.
