Deploying a Node-Todo App on AWS ECS Fargate and AWS ECR:

Prerequisites

Before we dive into the deployment process, make sure you have the following prerequisites in place:

1. AWS Account: You need an AWS account to access the AWS services required for this project.

2. Docker: Install Docker on your local machine. We'll use Docker to containerize the Node.js application.

3. Git: Ensure you have Git installed for version control and to clone the project repository.

4. Node.js: You'll need Node.js and npm (Node Package Manager) to run the Node.js application locally and install project dependencies.

5. AWS CLI: Install and configure the AWS Command Line Interface to interact with AWS services from your terminal.

Project Overview

In this project, we'll follow these steps:

1. Clone the Repository: Clone the Node Todo App repository from GitHub to your local machine using the following command:

    git clone https://github.com/Rohit123890/node-todo-cicd.git
   

2. Build the Docker Image: Navigate to the project directory and build a Docker image for the Node.js application. Make sure you have a Dockerfile in the project directory for this step.

    cd node-todo-cicd
    docker build -t node-todo-app .
   

3. Push the Docker Image to ECR: Create a repository in AWS ECR to store the Docker image. Then, push the image to ECR.

   • Create an ECR repository using the AWS Management Console or AWS CLI.

   • Authenticate Docker to your ECR registry using the AWS CLI:

       aws ecr get-login-password --region <your-region> | docker login --username AWS --password-stdin <your-account-id>.dkr.ecr.<your-region>.amazonaws.com
     

   • Tag your Docker image and push it to ECR:

       docker tag node-todo-app:latest <your-account-id>.dkr.ecr.<your-region>.amazonaws.com/node-todo-app:latest
       docker push <your-account-id>.dkr.ecr.<your-region>.amazonaws.com/node-todo-app:latest
     

4. Create an ECS Cluster: Using the AWS Management Console or AWS CLI, create an ECS cluster. This cluster will host our Fargate tasks.

5. Create an ECS Task Definition: Define a task definition that specifies how the Docker container should run in ECS. Ensure you reference the ECR image you pushed in step 3.

6. Create an ECS Service: Create an ECS service within your cluster and associate it with the task definition. Configure the service to run on AWS Fargate.

7. Access the Application: Once the ECS service is up and running, you'll be able to access your Node-Todo App using the public IP or DNS provided by AWS.

Conclusion

Congratulations! You've successfully deployed a Node-Todo App on AWS ECS Fargate using AWS ECR for container image storage. This project provides a practical introduction to containerization, AWS services, and the deployment process.

Remember to manage your AWS resources carefully to avoid unexpected charges. Additionally, consider implementing security best practices for your production deployments, such as setting up VPCs, security groups, and IAM roles.
