Docker Template for RMI Courseworks 馃惓

Coursework 1 Branch | For Courseworks 1 and 2 | (check the branch list for available templates)

This repo is a good template if you want to run your RMI work using Docker. This would mean that you do not need to install Java on computer to build/run your code and the RMI registry.

In here is just the calculator example that can be found on Moodle.

Tested on Docker for Mac and Linux and Windows 10

Requires

  • Docker Engine
  • Docker CLI
  • Docker Compose

How

  1. Clone me from this git repo: git clone https://github.com/scc311/rmi-docker-template -b cw1 rmi-cw
  2. Change to the cloned root directory: cd rmi-cw (this should put you in the same directory as this README)
  3. Make sure your client code is in the client-code directory.
  4. Update the client-code/entrypoint.sh's java command to the file with the name of the file with your main in it.
    • (without the .java extension)
  5. Any reference to localhost in your client (specifically your rmi lookup), needs to be replaced with DockerUtility.getRegistryHost().
  6. Make sure your server code is in the server-code directory.
  7. Update the server-code/entrypoint.sh's java command to the file with the name of the file with your main in it.
    • (without the .java extension)
  8. Make sure your interface code is in the interface-code directory.
  9. From the root directory of those 3 folders (the one with this README in) 1. To build your code (or re-build after you make changes), run: docker-compose build 2. To run the registry, server, and client, run: docker-compose up 3. Use Ctrl-C to get out of the container's tty.

鈿狅笍 The container images will contain your coursework! DO NOT push the built images to a public container registry!

How [without docker-compose]

馃毃 Life is easier with compose, so you don't really need this...

  • Much like in the steps above, make sure you code is divided up and in the correct directories. These steps just replace step 9.
  • All command below should be run from the root directory.
  • If you can, use tmux or different terminal windows for the client and server.

Build & Run the Server

  1. From the root directory (with the README in), run the following to build the container image (and your server code): 
    docker build --rm -f server-code/Dockerfile -t rmi-server .
  2. Next, to run your server (and simultaneously start the registry), run: 
    docker run --rm -it --network host --privileged rmi-server

Build & Run the Client

  1. From the root directory (with the README in), run the following to build the container image (and your client code): 
    docker build --rm -f client-code/Dockerfile -t rmi-client .
  2. Next, to run your client, run: 
    docker run --rm -it --network host --privileged rmi-client
