## Containerize an Application
1. Clone an open source project you would like to containerize. A couple of suggestions:
```
https://github.com/bregman-arie/node-hello-world
https://github.com/bregman-arie/flask-hello-world
```
`git clone https://github.com/bregman-arie/node-hello-world`
2. Write a Dockerfile you'll use for building an image of the application (you can use any base image you would like)
```
FROM alpine
LABEL maintainer="your name/email"
RUN apk add --update nodejs nodejs-npm
COPY . /src
WORKDIR /src
RUN npm install
EXPOSE 8080
ENTRYPOINT ["node", "./app.js"]
```
