Docker Mini project : Containerize an amazing Node JS Portfolio App
16 min readFeb 9, 2022
In this article we will be building a very simple yet amazing node js server app that serves your portfolio website with few lines of code. Then we will Containerize the app. Please note that the blog focuses on the Containerizing part more, rather paying attention to the codes for node. let’s jump into the first step to prepare our server.
Step 1 : Create your portfolio Website within few seconds
You don’t know how to code HTML/CSS or any web framework to build the site? Don’t worry chap, follow this link for a readymade template. Feel free to choose if you like any other template and play with it. Once your HTML/CSS format is ready with the below code lets create our node js server with just few lines of code.

Step 2: Prepare your node js Server in just few lines of code
Don’t worry if you don’t know node. In a life of DevOps, there will be frequent instances when you will be provided with the code, you just need to build image from it. Let’s create the server.js file and stuff the below with HTML/CSS embedded in it.
const express = require('express');const app = express();app.get('/', (req, res) => {res.send(`<!DOCTYPE html><html><title>W3.CSS Template</title><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1"><link rel="stylesheet" href="https://www.w3schools.com/w3css/4/w3.css"><link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Lato"><link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css"><style>body,h1,h2,h3,h4,h5,h6 {font-family: "Lato", sans-serif;}body, html {height: 100%;color: #777;line-height: 1.8;}/* Create a Parallax Effect */.bgimg-1, .bgimg-2, .bgimg-3 {background-attachment: fixed;background-position: center;background-repeat: no-repeat;background-size: cover;}/* First image (Logo.

Step 3: Let’s create the dependency files
Before proceeding with the containerization let’s crate our package.json file on the same folder with below code.
{"name": "docker-complete","version": "1.0.0","description": "","main": "server.js","license": "MIT","dependencies": {"express": "^4.17.1","body-parser": "1.19.0"}}
Step 4: Let’s create the dockerfile
Now that we are ready with our node js server and HTML/CSS template let’s create a file with the exact name Dockerfile in the same folder with below code.
FROM node
WORKDIR /app
COPY . /app/
RUN npm install
EXPOSE 80
CMD ["node", "server.js"]These few lines of code are enough to build your image. The first lines defines the base image of your container is node and 2nd line tells you the working directory i.e. the commands should be executing from /app/ inside container. COPY command copies every other files inside /app/ then RUN command get’s exevcuted. EXPOSE commands tells which port to run in while the CMD command gets executed when the container gets launch.
Step 5: Run your container
Once you are done with everything excute the below commands from the command prompt from the same location.
$ sudo docker build .This should be successfull and show you the container id in the output console like below.
If you find any issue audit your code with my github repo . Once done, finally it is time to run and map the port with host to conytainer. Run the below command.
$ sudo docker run -p 80:80 conatiner_idThis would show you nothing in console but open your browser and hit localhost:80 and voild you can find the portfolio running. What is next ?
This is the basic fun project for understanding the essence of containerization. Try to make the portfolio more realistic, find the best parctice, ctretae the following the best practices and then push the image to dockerhub registry. Comment if you have other ideas and share screenshot of what you have made. Thank you have a good day.
