ECE 438 containerized

This is a development environment for ECE 438, replacing virtual machines with containers.

Docker Hub: https://hub.docker.com/repository/docker/metricvoid/ece438

Note: Compatibility not guaranteed.

Note: this is not a production image and is not optimized for size.

Features

  1. The IP address of each container is displayed in the prompts

    root@ece438-1[172.17.0.3]:/repo#

  2. The repo folder is stored on host machine and shared across all containers. You can write code on the host machine and compile&run them in containers.

  3. SSH access between containers. All containers have user root with password root.

  4. Docker provides DNS service for the network bridge. e.g. ece438-1 will resolve to 172.17.0.3 in the example above.

Networking

  1. All containers have an IP address in CIDR 172.17.0.0/16.
  2. Containers can communicate with each other.
  3. Containers can access the host. The host is at 172.17.0.1.
  4. On Linux hosts, the host can access the container with their IPs. On Mac and Windows hosts, the host cannot access the containers.

Usage.

  1. Install Docker
  2. Clone the repository
  3. Clone your ECE 438 repository into the repo/ folder.
  4. Use the scripts.
    • Start-Container Start a container. (You may want multiple containers.) Containers are numbered with IDs
    • Attach-Container Attach to the console of a container for various operations.
      • Cannot attach to a stopped container.
      • Do not use exit or logout to detach. Use Ctrl-P Ctrl-Q.
    • Stop-AllContainers to stop all ECE438 containers.
    • Remove-AllContainers to remove all ECE438 containers.
  5. You will be dropped into /repo in the containers. Use ls to discover your code.
