# docker-ubuntu-vnc

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

## Usage

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

then the security type of vncserver is set to None,
it is **insecure** when exposing the container on the Internet.

only the following applications are installed by default:

* Xfce desktop

* Vim
* Chromium browser

## Build

```
docker build -t ubuntu-vnc .
```
