Connecting to WinCC Unified PC RT OpenPipe from Docker

I am trying to write an Edge app that will work with both WinCC Unified PC RT and a WinCC Unified Comfort Panel.  Since the only open interface that the UCP supports right now is OpenPipe, that i s what I am trying to use.  I can get my Edge app running on the UCP by following the volume mapping syntax described in https://support.industry.siemens.com/cs/us/en/view/109778780.  However, I have less success in connecting to OpenPipe on the PC.

My node.js application runs find when node.js is running directly in Windows.  However, when running in the docker container, I either get errors when I specify the volume mapping in the docker run command, or I get ECONNREFUSED errors when I try to connect to the OpenPipe in my application.   The docker run errors occur when I use:

docker run -v \\\\.\\pipe\\HmiRuntime:/tempcontainer/HmiRuntime -it sa/nodessh sh

The error is:

docker: Error response from daemon: \\\\.\\pipe\\HmiRuntime%!(EXTRA string=is not a valid Windows path).

See 'docker run --help'.

 I have tried various variants of the syntax - in quotes, using / instead of \, with and without the HmiRuntime, but no joy.  https://stackoverflow.com/questions/47801477/can-i-use-named-pipes-inside-containers suggests that connecting to a Windows named pipe may only be possible on late versions of Windows Server (I am using Windows 10 Pro Workstation).

If anyone has figured out how to attach to a Windows named pipe from within a Linux docker container, I would appreciate your insight.

Hi mmckay,

We are also investigating on this topic currently.

I will give you an update a soon as we have any news.

have you tried something like:
