Configuring Source Code Repositories in AWS CodePipeline

less Copy code


AWS CodePipeline is a powerful service that enables developers to build, test, and deploy their applications automatically. To get started with CodePipeline, you need to configure your source code repositories, where the application code resides. This tutorial will guide you through the process of setting up source code repositories in CodePipeline and integrating them with other AWS services to create efficient CI/CD pipelines.

Step-by-step Guide

Follow these steps to configure source code repositories in AWS CodePipeline:

  1. Sign in to AWS Management Console: Log in to your AWS account and navigate to the CodePipeline service.
  2. Create a New Pipeline: Click on "Create pipeline" to start configuring your pipeline.
  3. Configure Source Stage: In the "Source" stage, select the source provider where your code is hosted. CodePipeline supports various providers like AWS CodeCommit, GitHub, Bitbucket, and Amazon S3.
  4. Connect to Repository: Follow the on-screen instructions to connect your repository to CodePipeline. Provide the necessary permissions to CodePipeline to access your repository.
  5. Choose Branch: Select the branch from the repository that you want CodePipeline to monitor for changes.
  6. Trigger Options: Configure the event that should trigger the pipeline execution. It can be based on code changes or scheduled builds.
  7. Configure Build and Test Stages: After configuring the source stage, you can add additional stages like build, test, and deployment. Each stage can have multiple actions.
  8. Save and Execute: Save the pipeline configuration, and it will start automatically whenever changes are detected in the source repository.

Example of AWS CLI commands to create a pipeline with a GitHub source repository:

aws codepipeline create-pipeline --cli-input-json file://pipeline-definition.json
aws codepipeline start-pipeline-execution --name MyPipeline

Common Mistakes

  • Providing incorrect repository credentials during the setup.
  • Not properly selecting the correct branch to monitor for changes.
  • Using incorrect repository URLs or access keys.
  • Overlooking the need to set up appropriate permissions for CodePipeline to access the repository.
  • Not setting up triggers correctly, leading to pipelines not automatically starting on code changes.


  1. Q: Can I use multiple source repositories in a single pipeline?

    Yes, you can configure multiple source stages with different repositories in the same pipeline.

  2. Q: Can I use a private repository as the source?

    Yes, you can use private repositories by providing the necessary credentials during the setup.

  3. Q: How do I handle branches with different configurations?

    You can create multiple pipelines or use pipeline branching to handle different configurations.

  4. Q: Can I use CodePipeline with serverless applications?

    Yes, CodePipeline can be used with serverless applications hosted on AWS Lambda.

  5. Q: What happens if there are no changes in the source repository?

    CodePipeline will not trigger a pipeline execution if no changes are detected.


Configuring source code repositories in AWS CodePipeline is a crucial step in setting up CI/CD pipelines. By connecting your repositories, you enable CodePipeline to monitor for changes and automatically trigger the pipeline execution. It ensures that your application's latest code is built, tested, and deployed with each code change, streamlining your software development process and accelerating application delivery.
