Example Voting App

A simple distributed application running across multiple Docker containers.

Architecture

• A front-end web app in Python which lets you vote between two options
• A Redis 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 web app which shows the results of the voting in real time

Notes

The voting application only accepts one vote per client browser. It does not register additional votes if a vote has already been submitted from a client.
