Description

Traditionally we see container running applications on the server side, leaving it’s presentation layer to typically a browse or, to interacte with the container via a command prompt. However, it’s also possible to run a container and use a X11 server to access a GUI. In this example, I’ll explain how to run a container on a Windows environment to use Visual Studio Code.

Prerequisites

Docker Image

A Docker Image available on Docker Hub:

• Visual-Studio-Code-on-Docker

Windows X11 server

• Xming

Configuration

1. Configure Xming X Server x0.hosts file with your ip address (e.g.:)

   localhost
   192.168.1.7

Note: default location is c:\Program Files (x86)\Xming\x0.hosts

Instructions for use on Windows

1. Make sure Xming is install and configured

2. Open a PowerShell command prompt.

3. Set the DISPLAY environment variable (make sure to replace <localhost>
   with you own settings)

    PS> set-variable -name DISPLAY -value <localhost>:0.0

4. Run a Docker image in interactive mode (replace <docker_image> with the designated image or with your own):

    PS> docker run -it --privileged -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix <docker_image>
