Quick Start

Get Docker for free from the Docker Store. 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.

Run in this directory:

$ 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: 4, dogs: 0 ... CATS 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

Kubernetes

Kubernetes and Helm chart support has been added to the repo. Instructions coming soon.

Amazon ECS with Fargate

Deploy to AWS ECS with Fargate

GKE
