Installing Docker 2022 Semester 2

Here are installation instructions for installing Docker and running the software required for ELEC3608 Computer Architecture.

1. Installation

2 Testing

2.1 Hello world

To test basic Docker functionality, type docker run hello-world in the command window. Your output should be something like:

$ docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world

Status: Downloaded newer image for hello-world:latest

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

Share images, automate workflows, and more with a free Docker ID:

2.2 X Server

We need to use the X Server to display graphical output. This tests X Windows basic functionality.

  • (Windows setup)
    1. In your Ubuntu window type docker run -it -v /tmp/X11-unix:/tmp/.X11-unix fr3nd/xeyes
  • (x86 MacOS X setup)
    1. Install homebrew (see
    2. Use homebrew to install xquartz ```brew install –cask xquartz’’’
    3. Run the Xquartz X Server program by clicking on the icon, an xterm window should appear
    4. Set “Allow connections from network clients” in XQuartz -> Preferences
    5. In the xterm window type (if you get an error with the xhost command, try a reboot)
       $ xhost +
       access control disabled, clients can connect from any hos
       $ export DISPLAY=host.docker.internal:0
       $ docker run --platform linux/amd64 -it -e DISPLAY=$DISPLAY fr3nd/xeyes 

You should see a window similar to below and the eyes should move with your mouse.


2.3 ELEC3608 Base Image

This tests the ELEC3608 base image. Make sure you have set up your X Server and can execute the previous Xeyes example.

  • (Windows) From your Ubuntu window type
    docker run -it -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY -v `pwd`:/config phwl/elec3608-base:latest
  • (MacOS x86 or M1) From xterm type
    docker run --platform linux/amd64 -it -e DISPLAY=$DISPLAY -v `pwd`:/config phwl/elec3608-base:latest

If everything works, a prompt should appear and ls should show your local directory that was mounted.

Within Docker, the directory on your local home directory will be mapped to your local directory. Use this to access your files and store your outputs. Verify you can also run xeyes.
