Deploy a web-based application as a Docker container image. After verifying that the image is successfully created, push it to Amazon Elastic Container Registry (Amazon ECR). Then, launch an Amazon Elastic Container Service (Amazon ECS) cluster and create an AWS Fargate profile. Finally, deploy the application to a Fargate cluster.
