Add your foreground process

vncmain.sh is a file which is a placeholder for foreground process running in VNC.

You can write a Dockerfile like this:

FROM oott123/novnc:latest
COPY vncmain.sh /app/vncmain.sh

And add foreground commands in your vncmain.sh:

#!/bin/bash
# Set them to empty is NOT SECURE but avoid them display in random logs.
export VNC_PASSWD=''
export USER_PASSWD=''

xterm

Then build and run your docker image. That's it!
