A developer is configuring a basic continuous delivery pipeline in AWS CodePipeline to automate software releases. The pipeline must retrieve source code from an AWS CodeCommit repository, compile the project using AWS CodeBuild, and deploy it to an Amazon ECS service using AWS CodeDeploy. Arrange the following steps in the correct chronological order from first to last to complete a single pipeline execution.
- 1CodePipeline detects a new commit in the AWS CodeCommit source repository and initiates the pipeline execution.
- 2The source stage retrieves the repository files and uploads them as an input artifact to the Amazon S3 artifact bucket.
- 3AWS CodeBuild retrieves the source artifact from Amazon S3, compiles the application, and produces a build output artifact.
- 4AWS CodeDeploy retrieves the build output artifact from Amazon S3 and deploys it to the target Amazon ECS service.
Answer
The correct order of pipeline execution is: first, detecting the change in CodeCommit; second, retrieving the source files and storing them in Amazon S3; third, building the application using AWS CodeBuild; and finally, deploying the application to Amazon ECS using AWS CodeDeploy.
A pipeline execution in AWS CodePipeline flows sequentially through stages. First, CodePipeline detects a change in the source repository. Second, the source stage retrieves the code and stores it in Amazon S3 as an input artifact. Third, AWS CodeBuild compiles the code and generates the build output artifact. Lastly, AWS CodeDeploy uses the build artifact to update the Amazon ECS service.
Step-by-Step Solution
Key Concept
AWS CodePipeline execution runs sequentially through stages (Source, Build, Deploy). Each stage processes input artifacts generated by previous stages and produces output artifacts for subsequent stages.
