通过VNC将Docker连接到X11失败

Question

I have an ubuntu server without a display which runs a vncserver and I access it via VNC.

On this server I have tried to run the chrome example from this blog : https://blog.jessfraz.com/post/docker-containers-on-the-desktop/

but it failed like this:

>./runChrome.sh 
Warning: '--cpuset' is deprecated, it will be replaced by '--cpuset-cpus' soon. See usage.

Any idea how to fix this ?

What might be going wrong ?

This worked:

docker run -e DISPLAY -v $HOME/.Xauthority:/home/ghc/.Xauthority --net=host -ti 80d81a4ae162 /bin/bash
