Day 85 - Deploying a Node.js App on AWS ECS Fargate and AWS ECR

Introduction:

Embarking on a journey to deploy a Node.js application on AWS ECS Fargate and AWS ECR can be an exciting and educational experience. In this article, we'll walk through the process step by step, from fetching a Node.js application from GitHub to running it on an ECS cluster.

Task 1: Obtain the Node.js Application from GitHub

1. Begin by selecting a Node.js application from GitHub that you'd like to deploy. Ensure that the repository contains a Dockerfile for containerization.
2. Clone the repository to your local machine using the following command:git clone <repository_url>

Task 2: Build the Dockerfile

1. Navigate to the cloned repository and locate the Dockerfile.
2. Build the Docker image using the following command:docker build -t <image_name> .

Task 3: Setup AWS CLI and AWS Login

1. Install the AWS CLI by following the instructions for your operating system: AWS CLI Installation Guide
2. Once installed, configure the AWS CLI by running:aws configureProvide your AWS Access Key ID, Secret Access Key, default region, and output format.
3. Login to your AWS account using the following command:aws ecr get-login-password --region <your_region> | docker login --username AWS --password-stdin <your_account_id>.dkr.ecr.<your_region>.amazonaws.com

Task 4: Setup an ECS Cluster

1. Open the AWS Management Console and navigate to the ECS service.
2. Create a new ECS cluster by following the on-screen instructions. Choose the Fargate launch type for simplicity.

Task 5: Create a Task Definition

1. In the ECS console, select "Task Definitions" and click "Create new Task Definition."
2. Choose Fargate as the launch type and specify the task definition details.
3. Under "Container Definitions," add a container with the image from your ECR repository.
4. Configure the required task settings and click "Create."

Task 6: Run the Project

1. Deploy a service on your ECS cluster using the task definition you just created.
2. Once the service is running, access the public IP or DNS of the Fargate task to view your Node.js application.
