Amazon Elastic Container Service (ECS) is a fully-managed container orchestration service that simplifies deploying, managing, and scaling containerized applications on AWS. With ECS, you can efficiently run and scale Docker containers across a cluster of EC2 instances or AWS Fargate compute resources without managing the underlying infrastructure. With ECS, you can also focus on developing and deploying your applications while AWS handles the infrastructure and scaling.
In this Cloud Lab, you will start by creating a private repository on Amazon ECR to store your Docker image. Next, you will create an EC2 instance and use it to build your Docker image before pushing it to your ECR repository. Once the Docker image is successfully uploaded to ECR, you will create an ECS cluster and an IAM role which you’ll use in creating task definitions. After that, you will define a task for your cluster by registering a task definition and specifying the Docker image and the resources required to run the container. Then, you will run the task on the ECS cluster, which will deploy the containerized application. Lastly, you will create two security groups that you will use later with the load-balancing ECS service.
By the end of this Cloud Lab, you'll have practical experience in creating an ECR repository, building a Docker image, and running a task on an ECS cluster. These skills are essential for anyone working with containerized applications on AWS and will help you ensure the scalability and reliability of your applications.
The following is the high-level architecture diagram of the infrastructure that you’ll create in this lab:
