-Create nodejs web app
+1. First, create a new directory where all the files would live. In this directory create a package.json file that describes your app and its dependencies: file package.json as following
+{{{
+{
+  "name": "docker_web_app",
+  "version": "1.0.0",
+  "description": "Node.js on Docker",
+  "author": "First Last <first.last@example.com>",
+  "main": "server.js",
+  "scripts": {
+    "start": "node server.js"
+  },
+  "dependencies": {
+    "express": "^4.16.1"
+  }
+}
+}}}
+With your new package.json file, run npm install. If you are using npm version 5 or later, this will generate a package-lock.json file which will be copied to your Docker image.
+
+2. Then, create a server.js file that defines a web app using the Express.js framework:
+
+{{{
+'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');
+});
+
+app.listen(PORT, HOST, () => {
+  console.log(`Running on http://${HOST}:${PORT}`);
+});
+}}}
+
