Here is my post about this project, which includes project architecture, design and summary

Set up Docker for Running Environment

Download official docker image from docker hub

$ docker pull node
$ docker pull redis
$ docker pull mongo

Run mongodb container

$ docker run --name mongodb --expose 27017 -p 27017:27017 -d mongo

Run redis container

$ docker run --name redis --expose 6379 -p 6379:6379 -d redis

Run docker nodejs and link to redis and mongodb

$ docker run -it --name node --link redis:redis --link mongodb:mongodb -p 3000:3000 -p 8080:8080 -p 8989:8989 -v /path/to/your/working/directory/:/app -d node

port 3000: webpack hot reload
port 8080: nodejs app
port 8989: nodejs debugger port
note your node container ID by running docker ps -a then run command docker exec -it <container ID> /bin/bash (on Mac) to go inside the node container
install webpack globally npm install webpack -g at the root of the node container
change listening port 80 in file app.js at line 46 to 8080 for development environment
run webpack from /app to build module bundle
run npm install from /app folder to install all model dependencies
run 'npm start' from /app folder to run node app
done! Now you are browse to http://localhost:8080 to sign up JChat anc start to chat with your friends!

Set up WebPack for Development Environment

install WebPack Development Server in the node container
```
npm install webpack-dev-server -g
```
uncomment lines marked as uncomment in webpack config file
run WebPack development server in the node container to start hot reload
```
webpack-dev-server --hot --inline
```
run node server by opening another docker machine while running WebPack dev server
done

MongoDB command

add new fields if the specified field does not exist

db.users.update( {"_id": ObjectId("56fd8b59226076750236d579")}, { $set : {"friendList" :[ {"id": '', "chID": '', 'userName':'mike', 'userStatus':'online', 'imgSrc':'/images/avatar.ico'}]}})
