# Docker-Node-Application-Sever
Creating a simple Node Application Sever using Docker
## Overview
This project aims at creating a simple Node-Express application server using Docker
## Part 1: Create Node Application
### Step 1: Create 'package.json'
```javascript
{
"name": "docker_web_app",
"version": "1.0.0",
"description": "Node.js on Docker",
"author": "Kaustubh Olpadkar ",
"main": "server.js",
"scripts": {
"start": "node server.js"
},
"dependencies": {
"express": "^4.16.1"
}
}
```
### Step 2: Install dependencies
```terminal
$ npm install
```
### Step 3: Create 'server.js'
```javascript
'use strict';
const express = require('express');
// Constants
const PORT = 8080;
const HOST = '0.0.0.0';
// App
const app = express();
app.get('/', (req, res) => {
res.send('Hello world\n');
});
app.listen(PORT, HOST);
console.log(`Running on http://${HOST}:${PORT}`);
```
## Part 2: Running Node Application in Docker
### Step 1: Create 'Dockerfile'
```
FROM node:8
# Create app directory
WORKDIR /usr/src/app
# Install app dependencies
# A wildcard is used to ensure both package.json AND package-lock.json are copied
# where available (npm@5+)
COPY package*.json ./
RUN npm install
# If you are building your code for production
# RUN npm install --only=production
# Bundle app source
COPY . .
EXPOSE 8080
CMD [ "npm", "start" ]
```
### Step 2: Create '.dockerignore'
```
node_modules
npm-debug.log
```
### Step 3: Build Docker Image
```
$ sudo docker run -p 49160:8080 -d kaustubh/node-web-app
```
### Step 4:
```
$ sudo docker run -p 49160:8080 -d kaustubh/node-web-app
```
Now our Application Server is running and you can access it through http://localhost:49160 in your browser.
