Difficulty: EasyAWS CodePipeline

A developer is configuring a standard release pipeline in AWS CodePipeline to automate deployment. The pipeline must pull source code from an AWS CodeCommit repository, run tests and compile the code using AWS CodeBuild, require a manual sign-off from the quality assurance team, and finally deploy the application to AWS Elastic Beanstalk.

Arrange the actions in the correct sequence of execution from first to last.

  1. 1Source action (AWS CodeCommit)
  2. 2Build action (AWS CodeBuild)
  3. 3Manual approval action
  4. 4Deploy action (AWS Elastic Beanstalk)

Answer

The correct sequence of actions in the pipeline is: Source action (AWS CodeCommit), Build action (AWS CodeBuild), Manual approval action, and Deploy action (AWS Elastic Beanstalk).
AWS CodePipeline processes stages sequentially. The pipeline must first fetch the source code, compile and test it in the build phase, pause for manual verification, and finally deploy the verified package.

Step-by-Step Solution

1
Retrieve the source code from AWS CodeCommit.
The latest revision of the source code is retrieved and package artifacts are created.
Subsequent stages require the source code to perform builds and deployments.
2
Trigger the AWS CodeBuild environment to compile the application and run unit tests.
The application code is verified and a deployment package is generated.
Building the application generates the necessary artifacts that need to be reviewed and deployed.
3
Halt the pipeline for a Manual Approval action.
The pipeline execution pauses, and a notification is sent to the QA team for review.
This guarantees that the built artifacts are verified and approved before they reach the production environment.
4
Deploy the application using the AWS Elastic Beanstalk deployment action.
The verified application version is deployed to the Elastic Beanstalk environment.
Deploying is the final step in the pipeline after the application has been built and approved.
