Serial/COM devices in docker-compose on Windows

docker

(Vplagov) #1

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?
