To deploy a cluster environment of containers using Amazon Elastic Container Service (ECS), you can follow these general steps:
Create an Amazon ECS cluster in the AWS Management Console.
Create a task definition for your application, which specifies the container image and any necessary configuration settings.
Create a service, which allows you to run and maintain a specified number of instances of your task definition.
Optionally, set up a load balancer to distribute traffic to your service.
Monitor and scale your application as needed
It's a broad topic and there are more steps and details that you might want to consider, depending on your specific needs, as well as prerequisites like setting up your AWS account, creating IAM roles and policies, etc. AWS has a detailed documentation that will guide you throughout the process.
