Dockerizing-Nodejs

Description

In this guide I'll build a Nodejs Hello World Web App using Docker for running the application. This guide will assume that you have already downloaded Docker and Node, if not, you can check the links to download them.

How to build

First of all we will make a new directory where all the files would live.

$~: cd desktop
$desktop: mkdir hello-world
$desktop: cd hello-world

The next step, we will clone this repository which contains all the files we need.

$hello-world: git clone https://github.com/jodeh/dockerizing-nodejs.git

Now we'll build the docker and check if the image was created.

$hello-world: docker build . -t <your username>/node-web-app
$hello-world: docker images

Last but not least we will run the image, we're going to map the port of 49160 to the port specified in the Dockerfile 8080. As well as we will run it in the detached mode which will run it in the background.

$hello-world: docker run -p 49160:8080 -d <your username>/node-web-app

Finally it's time for testing our work, you can basiclly go to your localhost with the port number we used 49160 or you can use this command.

$hello-world: curl 0.0.0.0:49160
