Example Voting App
|
|
=========
|
|
|
|
Getting started
|
|
---------------
|
|
|
|
Download [Docker](https://www.docker.com/products/overview). If you are on Mac or Windows, [Docker Compose](https://docs.docker.com/compose) will be automatically installed. On Linux, make sure you have the latest version of [Compose](https://docs.docker.com/compose/install/). If you're using [Docker for Windows](https://docs.docker.com/docker-for-windows/) on Windows 10 pro or later, you must also [switch to Linux containers](https://docs.docker.com/docker-for-windows/#switch-between-windows-and-linux-containers).
|
|
|
|
Run in this directory:
|
|
```
|
|
docker-compose up
|
|
```
|
|
The app will be running at [http://localhost:5000](http://localhost:5000), and the results will be at [http://localhost:5001](http://localhost:5001).
|
|
|
|
Alternately, if you want to run it on a [Docker Swarm](https://docs.docker.com/engine/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 .NET 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. |
