What is AWS CodePipeline?

AWS CodePipeline is a fully managed continuous integration and continuous delivery (CI/CD) service provided by Amazon Web Services (AWS). It allows you to automate the process of building, testing, and deploying your applications, ensuring fast and reliable releases. With AWS CodePipeline, you can set up a pipeline to automatically build, test, and deploy code changes to various environments, such as development, staging, and production, with ease.

How AWS CodePipeline Works

Setting up a basic AWS CodePipeline involves several steps:

  1. Source Stage: In this stage, you define the source code repository, such as AWS CodeCommit, GitHub, or Amazon S3, where your application code resides.
  2. Build Stage: Here, you specify the build environment and instructions to build your application. You can use AWS CodeBuild or other build tools like Jenkins or Gradle.
  3. Test Stage: In this stage, you can define test suites and run various tests, such as unit tests, integration tests, or load tests, to ensure the quality of your application.
  4. Deploy Stage: The deploy stage involves specifying the target deployment environment, such as Amazon EC2 instances, AWS Elastic Beanstalk, or Amazon S3, where your application will be deployed.

After you have set up the pipeline, whenever you push code changes to the source repository, AWS CodePipeline automatically triggers the pipeline, starting the build, test, and deployment process. Each stage runs sequentially, and you can define conditions for the pipeline to proceed or stop based on the success or failure of each stage.

Example of an AWS CodePipeline configuration:

- name: Source
- name: SourceAction
action_type: Source
provider: CodeCommit
RepositoryName: my-repo
BranchName: main
- name: Build
- name: BuildAction
action_type: Build
provider: CodeBuild
ProjectName: my-build-project
- name: Deploy
- name: DeployAction
action_type: Deploy
provider: CloudFormation
StackName: my-stack

Common Mistakes

  • Incorrectly configuring the source stage, leading to failed pipeline triggers.
  • Not setting up appropriate permissions for AWS CodePipeline to access other AWS services.
  • Overcomplicating the pipeline, making it challenging to manage and troubleshoot.
  • Not implementing proper error handling and retries in case of deployment failures.
  • Not regularly reviewing and optimizing the pipeline for better performance.


  1. Q: Can I use AWS CodePipeline with third-party build and deployment tools?

    Yes, AWS CodePipeline supports various build and deployment providers, including AWS CodeBuild, Jenkins, AWS Elastic Beanstalk, and more.

  2. Q: Is AWS CodePipeline suitable for serverless applications?
