In this 3rd and last part of 3-part series on ECR Repository, I am going to show you how to create a Fargate Cluster and a Service which uses the task definition that points to the image in the repository - nginx and access Docker image with Nginx from - Application Load Balancer and Fargate Cluster.

Fargate removes the need to provision and manage servers, lets you specify and pay for resources per application, and improves security through application isolation by design.

1st article

• As a reference, please read my 1st article - How to create a Docker Image with Nginx from an EC2 Instance and Push to ECR Repository

2nd article

• As a reference, please read my 2nd article -Create Task Definition in ECS and Application Load balancer (ALB) for the Task which is to be run on Fargate Cluster

Let’s get started!

Please visit my GitHub Repository for Docker/ECS/ECR articles on various topics being updated on constant basis.

Objectives:

1. Create Fargate cluster - my-ecs-cluster

2. Create a Service - my-service

3. Validate by accessing Docker image with Nginx from - Application Load Balancer and Fargate Cluster.

4. Cleanup

Pre-requisites:

• AWS user account with admin access, not a root account.
• AWS CLI.

Resources Used:

Amazon Elastic Container Service

AWS Fargate

Steps for implementation to this project:

1. Create Fargate cluster - my-ecs-cluster

• On the Amazon Elastic Container Service (ECS) Dashboard, Click Clusters, Create cluster, my-ecs-cluster, default vpc, 2 public subnets - us-east-1a, us-east-1b, Infrastructure - Your cluster is automatically configured for AWS Fargate (serverless)

• Create

2. Create a Service - my-service

• Click my-ecs-cluster

• Take the below values for creating a Service - my-service

• PHOTO-1

• PHOTO-2

• PHOTO-3

• PHOTO-4

• PHOTO-5

• PHOTO-6

• Create

my-service

3. Validate by accessing Docker image with Nginx from - Application Load Balancer and Fargate Cluster.

• Click cluster - ecs-cluster, click tab - Tasks, Click the task, Copy the Public IP

• paste the Public IP on a web browser

• Click my-ecs-alb, copy DNS name of ALB

• paste DNS name of ALB on a Web browser

4. Cleanup

• on the service - my-service, Desired-task - 0, Update

• then delete service, task, cluster, Load balancer, Target groups, EC2 instance, and service group

What we have done so far

• We have successfully created a Fargate Cluster and a Service which uses the task definition that points to the image in the repository - nginx and accessed Docker image with Nginx from - Application Load Balancer and Fargate Cluster.
