Deploying Containers on AWS ECS with Fargate

Introduction

Amazon Elastic Container Service (ECS) with AWS Fargate enables developers to deploy and manage containers without managing the underlying infrastructure. Fargate eliminates the need to provision or scale EC2 instances, providing a serverless approach to containerized applications.

This guide walks through deploying a containerized application on AWS ECS with Fargate using AWS CLI, Terraform, or the AWS Management Console.

1. Understanding AWS ECS and Fargate

✅ What is AWS ECS?

Amazon ECS (Elastic Container Service) is a fully managed container orchestration service that allows running Docker containers on AWS.

✅ What is AWS Fargate?

AWS Fargate is a serverless compute engine for ECS that removes the need to manage EC2 instances, providing:

Automatic scaling

Per-second billing

Enhanced security (isolation at the task level)

Reduced operational overhead

✅ Why Choose ECS with Fargate?

✔ No need to manage EC2 instances ✔ Pay only for the resources your containers consume ✔ Simplified networking and security ✔ Seamless integration with AWS services (CloudWatch, IAM, ALB)

2. Prerequisites

Before deploying, ensure you have:

AWS Account with permissions for ECS, Fargate, IAM, and VPC

AWS CLI installed and configured

Docker installed to build container images

An existing ECR (Elastic Container Registry) repository

3. Steps to Deploy Containers on AWS ECS with Fargate

Step 1: Create a Dockerized Application

First, create a simple Dockerfile for a Node.js or Python application.

Example: Node.js DockerfiledockerfileFROM node:16-alpine WORKDIR /app COPY package.json . RUN npm install COPY . . CMD ["node", "server.js"] EXPOSE 3000

Build and push the image to AWS ECR:shaws ecr create-repository --repository-name my-app docker build -t my-app . docker tag my-app:latest <AWS_ACCOUNT_ID>.dkr.ecr.<REGION>.amazonaws.com/my-app:latest aws ecr get-login-password --region <REGION> | docker login --username AWS --password-stdin <AWS_ACCOUNT_ID>.dkr.ecr.<REGION>.amazonaws.com docker push <AWS_ACCOUNT_ID>.dkr.ecr.<REGION>.amazonaws.com/my-app:latest

Step 2: Create an ECS Cluster

Use the AWS CLI to create a cluster:shaws ecs create-cluster --cluster-name my-cluster

Or use Terraform:hclresource "aws_ecs_cluster" "my_cluster" { name = "my-cluster" }

Step 3: Define a Task Definition for Fargate

The task definition specifies how the container runs.

Create a task-definition.js{ "family": "my-task", "networkMode": "awsvpc", "executionRoleArn": "arn:aws:iam::<AWS_ACCOUNT_ID>:role/ecsTaskExecutionRole", "cpu": "512", "memory": "1024", "requiresCompatibilities": ["FARGATE"], "containerDefinitions": [ { "name": "my-container", "image": "<AWS_ACCOUNT_ID>.dkr.ecr.<REGION>.amazonaws.com/my-app:latest", "portMappings": [{"containerPort": 3000, "hostPort": 3000}], "essential": true } ] }

Register the task definition:shaws ecs register-task-definition --cli-input-json file://task-definition.json

Step 4: Create an ECS Service

Use AWS CLI:shaws ecs create-service --cluster my-cluster --service-name my-service --task-definition my-task --desired-count 1 --launch-type FARGATE --network-configuration "awsvpcConfiguration={subnets=[subnet-xyz],securityGroups=[sg-xyz],assignPublicIp=\"ENABLED\"}"

Or Terraform:hclresource "aws_ecs_service" "my_service" { name = "my-service" cluster = aws_ecs_cluster.my_cluster.id task_definition = aws_ecs_task_definition.my_task.arn desired_count = 1 launch_type = "FARGATE" network_configuration { subnets = ["subnet-xyz"] security_groups = ["sg-xyz"] assign_public_ip = true } }

Step 5: Configure a Load Balancer (Optional)

If the service needs internet access, configure an Application Load Balancer (ALB).

Create an ALB in your VPC.

Add an ECS service to the target group.

Configure a listener rule for routing traffic.

4. Monitoring & Scaling

🔹 Monitor ECS Service

Use AWS CloudWatch to monitor logs and performance.shaws logs describe-log-groups

🔹 Auto Scaling ECS Tasks

Configure an Auto Scaling Policy:sh aws application-autoscaling register-scalable-target \ --service-namespace ecs \ --scalable-dimension ecs:service:DesiredCount \ --resource-id service/my-cluster/my-service \ --min-capacity 1 \ --max-capacity 5

5. Cleaning Up Resources

After testing, clean up resources to avoid unnecessary charges.shaws ecs delete-service --cluster my-cluster --service my-service --force aws ecs delete-cluster --cluster my-cluster aws ecr delete-repository --repository-name my-app --force

Conclusion

AWS ECS with Fargate simplifies container deployment by eliminating the need to manage servers. By following this guide, you can deploy scalable, cost-efficient, and secure applications using serverless containers.
