docker-ubuntu-vnc

An Ubuntu docker image to provide VNC access to Xfce desktop environment.

Usage

Simple usage:

docker run -d -p 5900:5900 -p 6080:6080 -e VNC_PASSWD=password dcsunset/ubuntu-vnc

Then visit http://localhost:6080 to visit noVNC UI. Or you can use a different VNC client (like TigerVNC client) and connect to localhost:5900.

If VNC_PASSWD is not set, then the security type of vncserver is set to None, it is insecure when exposing the container on the Internet.

Exposed ports

• 5900: Used for VNC interface
• 6080: Used for noVNC Web UI
