Voting App with Docker (Node.js version)

Quick Start

Install Docker. This app will work with versions from either the Stable or the Edge channels.

If you're using Docker for Windows on Windows 10 pro or later, you must also switch to Linux containers.

In the project's root directory, run:

$ docker-compose up

You can test it with the voter CLI:

$ docker run -it --rm --network=host subfuzion/voter vote
? What do you like better? (Use arrow keys)
  (quit)
❯ cats
❯ dogs

You can print voting results:

$ docker run -it --rm --network=host subfuzion/voter results
Total votes -> cats: 0, dogs: 1 ... DOGS WIN!

When you are finished:

Press Ctrl-C to stop the stack, then enter:

$ docker-compose -f docker-compose.yml rm -f

Docker Swarm

You can also run it on a Docker Swarm. If you haven't initialized one yet, run:

$ docker swarm init

Once you have initialized a swarm, then deploy the stack:

$ docker stack deploy --compose-file docker-stack.yml vote

You can test it the same way as described for docker-compose. When finished, you can stop the stack by entering:

$ docker stack rm vote
