Dockerizing a Node.js Web App

Welcome to the Dockerizing a Node.js web app repository! In this project, we'll guide you through the process of containerizing a Node.js web application using Docker. Docker makes it easy to package your application and its dependencies into a single, portable container that can run consistently across different environments.

Prerequisites

Before you get started, make sure you have the following prerequisites installed on your local machine:

• Docker
• Git (for cloning the repository)

Getting Started

Follow these steps to build and run the Node.js web app using Docker on your local machine.

Clone the Repository

If you haven't already clone this repository to your local machine using Git then folow this two instractions:

git clone https://github.com/Harasisco/Dockerizing_Node.js.git
cd dockerizing-nodejs-web-app

Build the Docker Image

To build the Docker image for the Node.js web app, run the following command in the project directory:

docker build . -t <your username>/node-web-app

This command will create a Docker image named <your username>/node-web-app.

Check the image using:

docker images

Run the Docker Container

Now that you have built the Docker image, you can run the Node.js web app in a Docker container. Use the following command:

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

This command will start a Docker container in detached mode, exposing port 8080 of the container to port 49160 on your local machine.

Accessing the Application

Once the Docker container is running, you can access the Node.js web app in your web browser by navigating to http://localhost:49160.

Or you can call your app using curl (install if needed via: sudo apt-get install curl ):

curl -i localhost:49160

Customization

Feel free to customize the Node.js web app and the Docker configuration to suit your needs. You can modify the source code in the server.js file and update the Dockerfile as necessary.
