Correct Answers: B, D.
AWS CodePipeline job workers for container actions, such as an Amazon ECR source action or Amazon ECS deploy actions, use definitions files to map the image URI and container name to the task definition.
Each definition file is a JSON-formatted file used by the action provider.
Amazon ECS standard deployments require an imagedefinitions.json file as an input to the deploy action.
Also, a buildspec is a collection of build commands and related settings.
If you include a buildspec as part of the source code, by default, the buildspec file must be named buildspec.yml and placed in the root of your source directory.
Incorrect Answers:
Option A is incorrect because Jenkinsfile (a text file that contains the definition of a Jenkins Pipeline) is not part of the AWS CodePipeline steps and is also irrelevant for this question.
Option C is incorrect because you can describe the phases of a Docker image build in AWS CodeBuild by using the buildspec.yml file instead of a Dockerfile (a text document that contains all the commands to assemble a Docker image).
Option E is incorrect because the buildspec.yml file does not have anything to do with Amazon ECS.

In this scenario, you are modernizing the CI/CD processes to deploy Docker containers using Amazon ECS as the standard deployment. You also need to integrate AWS CodeBuild into AWS CodePipeline to provide high availability. Additionally, there are source code changes for the Docker image.
Here are the relevant statements that are true in this case:
B. Use the imagedefinitions.json file to describe in AWS CodePipeline the container application. The imagedefinitions.json file is used in AWS CodePipeline to define the container application to be deployed to Amazon ECS. This file specifies the container name, tag, and repository URL. It also defines any additional container settings, such as environment variables, memory and CPU limits, and port mappings.
D. Use the buildspec.yml file to describe in AWS CodeBuild the phases of a Docker image build. The buildspec.yml file is used in AWS CodeBuild to define the phases of a Docker image build. This file includes information about the environment, such as the base image to use, and the steps to build and push the Docker image to the Amazon ECR repository.
A, C, and E are incorrect options: A. Use the Jenkinsfile to describe in AWS CodePipeline the steps to be deployed. The Jenkinsfile is a configuration file used in Jenkins, not AWS CodePipeline. It is not relevant in this scenario.
C. Use the Dockerfile to describe in AWS CodeBuild the phases of a Docker image build. The Dockerfile is used to define the image build process, but it is not relevant in this scenario because the question asks about integrating AWS CodeBuild with AWS CodePipeline.
E. Use buildspec.yml file to describe in Amazon ECS the phases of a Docker image build. The buildspec.yml file is used in AWS CodeBuild, not Amazon ECS. It is used to define the phases of a Docker image build, but it is not relevant in this scenario because the question asks about integrating AWS CodeBuild with AWS CodePipeline.
