Download Docker. If you are on Mac or Windows, Docker Compose will be automatically installed. On Linux, make sure you have the latest version of Compose.
Run in this directory:
docker-compose up
The app will be running at http://localhost:8181, and the results will be at http://localhost:8080.
Alternately, if you want to run it on a Docker Swarm, first make sure you have a swarm. If you don't, run:
docker swarm init
Once you have your swarm, in this directory run:
docker stack deploy --compose-file docker-stack.yml vote
- A Python webapp which lets you vote between two options
- A Redis queue which collects new votes
- A Java worker which consumes votes and stores them in…
- A Postgres database backed by a Docker volume
- A Node.js webapp which shows the results of the voting in real time
Note:
The voting application only accepts one vote per client. It does not register votes if a vote has already been submitted from a client.
