Docker runtime for the UNIX programming class.

• Clone this repo

• Build the required image upclass/runtime using the command:

  ./build.sh
  

  You only need to do this once, unless the files placed in the debian folder is modified.

• Create the runtime instance using the command:

  ./start.sh [password]
  

  The script will create a docker container named up-runtime. It detects the current user's login ID, user ID, and group ID, and then creates the same user within the docker container using a default password of password. To change the default password, provide the desired password as the first argument when running the script. Alternatively, you can log into the docker container using the following command:

  ssh -p 22222 <your-username>@localhost
  

  Please note that the script must be run as a regular user. Ensure that your environment allows a regular user to run the docker command. By default, it works with Docker Desktop on macOS or a Windows terminal with WSL integration. For Linux users, you may need to add the current user to the docker group.

  You only need to do this once. The container will automatically start when the docker service is started.

• Stop the runtime

  docker stop up-runtime
  

• Destroy the runtime

  docker rm up-runtime
  

  You may also want to delete the ./home directory created in the same directory of this repo.

• Destroy the image for the runtime

  docker rmi upclass/runtime
