Socket.IO Chat with traefik & redis

A simple chat demo for Socket.IO

How to use

Install Docker Compose, then:

$ docker-compose up -d

And then point your browser to http://localhost:3000.

You can then scale the server to multiple instances:

$ docker-compose up -d --scale=server=7

The session stickiness, which is required when using multiple Socket.IO server instances, is achieved with a cookie. More information here.
