|
|
==================
|
|
|
|
This is an example Docker app with multiple services. It is run with Docker Compose and uses Docker Networking to connect containers together.
|
|
|
|

Architecture
|
|
-----
|
|
|
|
* 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
|
|
|
|
Running
|
|
-------
|
|
|
|
Since this app makes use of Compose's experimental networking support, it must be started with:
|
|
|
|
$ cd vote-apps/
|
|
$ docker-compose --x-networking up -d
|
|
|
|
The app will be running on port 5000 on your Docker host, and the results will be on port 5001.
