Serial/COM devices in docker-compose on Windows

Docker Desktop

Hello.
I’m using Docker for Windows 10 and just updated to the following version: 17.12.0-ce-win46 (15048). Compose: 1.18.0.

An application that I’m running with compose uses Serial/COM port of a host machine. This is how I set it up in compose file:

devices:
    - "/dev/ttyS3:/dev/ttyS3"

Serial device in Windows is connected on COM4.

When I run the whole set (a Java application), I get a NoSuchPortException. Turns out that host COM4 port wasn’t forwarded into container.

Is it the right approach to map Windows COM port to a container with compose?
Does Docker for Windows actually support this functionality?

No feedback at all on this? Bump.

Looks like it’s not possible to map between linux and windows hosts according to this:

Would be too cool…

Hello,

Was this problem ever solved ?

Kind Regards Henrique

I know that if we use Docker desktop with WSL2, then we can map the USB/Serial ports from Windows to WSL2. But it would be very nice if Docker supports this feature out of the box.

Thanks
