rigormortiz/ubuntu_novnc repository overview

⁠docker_ubuntu_novnc

⁠What is docker_ubuntu_novnc anyway?

It is a Ubuntu zesty base image with x11vnc and novnc installed. It is intended to act as the base image for a full desktop environment like Mate, KDE, xfce, i3, etc. Please see my other repositories for examples.

⁠Usage

Dockerfile

FROM rigormortiz/ubuntu_novnc:zesty

...

⁠Noteworthy

⁠Supervisor

This image is based on my ubuntu supervisor image and, as such, runs on supervisor. Desktops based on this image will need to ship a supervisor config file similar to this one: (mate)

[program:dbus]
priority=14
directory=/
command=dbus-launch
user=%(ENV_DESKTOP_USERNAME)s
autostart=true
autorestart=true

[program:mate]
priority=15
directory=/home/%(ENV_DESKTOP_USERNAME)s
command=/usr/bin/mate-session
user=%(ENV_DESKTOP_USERNAME)s
autostart=true
autorestart=true
environment=DISPLAY=":1",HOME="/home/%(ENV_DESKTOP_USERNAME)s"

⁠Exposed ports

• x11vnc is exposed on port 5900
• noVNC's http interface is exposed on port 6080

⁠Misc.

• Default user is ubuntu. This can be changed via the DESKTOP_USERNAME variable in the Dockerfile
• Default VNC password is currently the same as DESKTOP_USERNAME. See TODO in next section. It can be easily changed at runtime with:

x11vnc -storepasswd somePassword /home/${DESKTOP_USERNAME}/.vnc/passwd

⁠TODO

• support for ssl
• dynamically generated VNC password
