Dockerized Node.js Application

This project demonstrates how to dockerize a simple Node.js application. Dockerization creates a Docker image that packages the application along with its dependencies, making it portable and consistent across different environments.

---

Prerequisites

• Node.js: Installed locally for testing the application before containerization.
• Docker: Installed to run and manage Docker containers.

Getting Started

1. Clone the repository to your local machine:

   git clone https://github.com/SHUHAIB-T/docker-node.git
   cd docker-node

2. Install the dependencies for the Node.js application:

npm install

Dockerizing the Application

1. Build the Docker Image To create the Docker image for this application, run the following command:

   docker build -t docker-node .

2. Run the Docker Container Start a Docker container from the image, mapping port 8000 of the container to port 8000 on your local machine: bash docker run -p 8000:8000 docker-node After running this command, the application will be accessible at http://localhost:8000. You should see a message confirming that the app is running.

Testing the Application

You can test the application using Postman or cURL.

Example cURL Request

Use the following command to send a POST request to the application:

curl --location 'http://localhost:8000/test' \
--header 'content-type: application/json' \
--data '{
	"msg": "testing"
}'

Notes

• Make sure that port 8000 is available on your machine before running the container.
• The Dockerfile provided in this project is configured to copy only the necessary files to the Docker image, keeping it lightweight.

Enjoy working with Dockerized applications!
