Local project connecting to dockerized cote services on macOS

[rankun203]

Issue: Both services cannot talk to each other.

• Local developing project: Our current project is running using VS Code's run script, a normal script.
• Dockerized cote service: Some of our services are just plain docker containers that are already running locally, we are now trying to connect to them.
• macOS: We are using Docker for Mac, with docker-compose.

Tried solutions:

• Using network_mode: host on docker-compose services, did not work.
• privileged: true, did not work.

Verified, on Linux, network_mode: host will just do the work.

On Mac however, it won't work, see this issue (docker/for-mac#1031).
