9

There are plenty of resources online about using VNC with a linux container, but none that I can find for windows containers, so I thought I'd give it a crack.

I can get the tightVNC server to start (authentication disabled), and the listening ports of 5900 and 5800 appear in the container. However when the client viewer attempts to establish a connection, the best I get is - connection has been gracefully closed

So I enabled level 9 logging on the tightVNC server and here is the section of the log where the incoming connection starts.

I have tried this both on mcr.microsoft.com/windows/servercore:ltsc2019 and mcr.microsoft.com/windows:1903 base images, and both produce the same client message, and similar logs.

I've tried

  • Running the VNC server under the default ContainerAdministrator account
  • Creating a new user account with Admin membership, and running the VNC under that account
  • --isolation process --device class/5B45201D-F2F2-4F3B-85BB-30FF1F953599 from here
  • the --gpus all docker run option (as a guess)

But all hacks so far are fruitless.

I have no idea if it is even possible, but any suggestions/ideas looking at the VNC logs as to what else to could try/hack ? Suggestions on why the RFB init access id denied ?
