Node.js Hello World app running on Ubuntu using docker

Dockerfile

Node.js Hello World

Node.js Hello World on CentOS using docker.

Prerequisites

Node.js & npm

Getting Started

Start Ubuntu virtual machine using Vagrant (required to run docker):
```
vagrant up
```
SSH into virtual machine:
```
vagrant ssh
```
Install dependencies:
```
cd /vagrant
make install
```

Build docker image:

make build
# docker build -t gasi/centos-node-hello .

Run app:

make run-container
# docker run -p 49160:8080 -d gasi/centos-node-hello

Install curl:
```
sudo apt-get install curl
```

Get mapped port (last column) using, e.g. 49160:

docker ps

> # Example
> ID                  IMAGE                           COMMAND              CREATED             STATUS              PORTS
> ecce33b30ebf        gasi/centos-node-hello:latest   node /src/index.js   10 seconds ago      Up 9 seconds        49160->8080

Test app using the port in previous step, e.g. 49160:
```
curl localhost:<port>

# Example
# curl localhost:49163
```
It should print Hello World to the console.
