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 -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.
