# noVNC Display Container
```
```
This image is intended to be used for displaying X11 applications from other containers in a browser. A stand-alone demo as well as a [Version 2](https://docs.docker.com/compose/compose-file/#version-2) composition.
## Image Contents
* [Xvfb](http://www.x.org/releases/X11R7.6/doc/man/man1/Xvfb.1.xhtml) - X11 in a virtual framebuffer
* [x11vnc](http://www.karlrunge.com/x11vnc/) - A VNC server that scrapes the above X11 server
* [noNVC](https://kanaka.github.io/noVNC/) - A HTML5 canvas vnc viewer
* [Fluxbox](http://www.fluxbox.org/) - a small window manager
* [xterm](http://invisible-island.net/xterm/) - to demo that it works
* [supervisord](http://supervisord.org) - to keep it all running
## Usage
### Variables
You can specify the following variables:
* `DISPLAY_WIDTH=` (1024)
* `DISPLAY_HEIGHT=` (768)
* `RUN_XTERM={yes|no}` (yes)
* `RUN_FLUXBOX={yes|no}` (yes)
### Stand-alone Demo
Run:
```bash
$ docker run --rm -it -p 8080:8080 theasp/novnc
```
Open a browser and see the `xterm` demo at `http://:8080/vnc.html`
### V2 Composition
A version of the [V2 docker-compose example](https://github.com/theasp/docker/blob/master/docker-compose.yml) is shown below to illustrate how this image can be used to greatly simplify the use of X11 applications in other containers. With just `docker-compose up -d`, your favorite IDE can be accessed via a browser.
Some notable features:
* An `x11` network is defined to link the IDE and novnc containers
* The IDE `DISPLAY` environment variable is set using the novnc container name
* The screen size is adjustable to suit your preferences via environment variables
* The only exposed port is for HTTP browser connections
