# Docker Chat Demo
Companion repo for this article on my blog:
- [Lessons from Building a Node App in Docker](https://jdlm.info/articles/2019/09/06/lessons-building-node-app-docker.html) (2019 update).
- [Lessons from Building a Node App in Docker](http://jdlm.info/articles/2016/03/06/lessons-building-node-app-docker.html) (2016 original).
Contains step-by-step examples used in the article to get the [socket.io chat example](http://socket.io/get-started/chat) running in Docker.
