Run the 'Bitbucket pull request and webhook filter' sample for CodeBuild

AWS CodeBuild supports webhooks when the source repository is Bitbucket. This means that for a CodeBuild build project that has its source code stored in a Bitbucket repository, webhooks can be used to rebuild the source code every time a code change is pushed to the repository. For more information, see Bitbucket webhook events.

This sample shows you how to create a pull request using a Bitbucket repository. It also shows you how to use a Bitbucket webhook to trigger CodeBuild to create a build of a project.

Note

When using webhooks, it is possible for a user to trigger an unexpected build. To mitigate this risk, see Best practices for using webhooks.

Prerequisites

To run this sample you must connect your AWS CodeBuild project with your Bitbucket account.

Note

CodeBuild has updated its permissions with Bitbucket. If you previously connected your project to Bitbucket and now receive a Bitbucket connection error, you must reconnect to grant CodeBuild permission to manage your webhooks.

Step 1: Create a build project with Bitbucket and enable webhooks

The following steps describe how to create an AWS CodeBuild project with Bitbucket as a source repository and enable webhooks.

  1. Open the AWS CodeBuild console at https://console.aws.amazon.com/codesuite/codebuild/home.

  2. If a CodeBuild information page is displayed, choose Create build project. Otherwise, on the navigation pane, expand Build, choose Build projects, and then choose Create build project.

  3. Choose Create build project.

  4. In Project configuration:

    Project name

    Enter a name for this build project. Build project names must be unique across each AWS account. You can also include an optional description of the build project to help other users understand what this project is used for.

  5. In Source:

    Source provider

    Choose Bitbucket. Follow the instructions to connect (or reconnect) with Bitbucket and then choose Authorize.

    Repository

    Choose Repository in my Bitbucket account.

    If you have not previously connected to your Bitbucket account, enter your Bitbucket username and app password, and select Save Bitbucket credentials.

    Bitbucket repository

    Enter the URL for your Bitbucket repository.

  6. In Primary source webhook events, select the following.

    Note

    The Primary source webhook events section is only visible if you chose Repository in my Bitbucket account in the previous step.

    1. Select Rebuild every time a code change is pushed to this repository when you create your project.

    2. From Event type, choose one or more events.

    3. To filter when an event triggers a build, under Start a build under these conditions, add one or more optional filters.

    4. To filter when an event is not triggered, under Don't start a build under these conditions, add one or more optional filters.

    5. Choose Add filter group to add another filter group, if needed.

    For more information about Bitbucket webhook event types and filters, see Bitbucket webhook events.

  7. In Environment:

    Environment image

    Choose one of the following:

    To use a Docker image managed by AWS CodeBuild:

    Choose Managed image, and then make selections from Operating system, Runtime(s), Image, and Image version. Make a selection from Environment type if it is available.

    To use another Docker image:

    Choose Custom image. For Environment type, choose ARM, Linux, Linux GPU, or Windows. If you choose Other registry, for External registry URL, enter the name and tag of the Docker image in Docker Hub, using the format docker repository/docker image name. If you choose Amazon ECR, use Amazon ECR repository and Amazon ECR image to choose the Docker image in your AWS account.

    To use a private Docker image:

    Choose Custom image. For Environment type, choose ARM, Linux, Linux GPU, or Windows. For Image registry, choose Other registry, and then enter the ARN of the credentials for your private Docker image. The credentials must be created by Secrets Manager. For more information, see What Is AWS Secrets Manager? in the AWS Secrets Manager User Guide.

    Service role

    Choose one of the following:

    • If you do not have a CodeBuild service role, choose New service role. In Role name, enter a name for the new role.

    • If you have a CodeBuild service role, choose Existing service role. In Role ARN, choose the service role.

    Note

    When you use the console to create or update a build project, you can create a CodeBuild service role at the same time. By default, the role works with that build project only. If you use the console to associate this service role with another build project, the role is updated to work with the other build project. A service role can work with up to 10 build projects.

  8. In Buildspec, do one of the following:

    • Choose Use a buildspec file to use the buildspec.yml file in the source code root directory.

    • Choose Insert build commands to use the console to insert build commands.

    For more information, see the Buildspec reference.

  9. In Artifacts:

    Type

    Choose one of the following:

    • If you do not want to create build output artifacts, choose No artifacts.

    • To store the build output in an S3 bucket, choose Amazon S3, and then do the following:

      • If you want to use your project name for the build output ZIP file or folder, leave Name blank. Otherwise, enter the name. By default, the artifact name is the project name. If you want to use a different name, enter it in the artifacts name box. If you want to output a ZIP file, include the zip extension.

      • For Bucket name, choose the name of the output bucket.

      • If you chose Insert build commands earlier in this procedure, for Output files, enter the locations of the files from the build that you want to put into the build output ZIP file or folder. For multiple locations, separate each location with a comma (for example, appspec.yml, target/my-app.jar). For more information, see the description of files in Buildspec syntax.

    Additional configuration

    Expand Additional configuration and set options as appropriate.

  10. Choose Create build project. On the Review page, choose Start build to run the build.

Step 2: Trigger a build with a Bitbucket webhook

For a project that uses Bitbucket webhooks, AWS CodeBuild creates a build when the Bitbucket repository detects a change in your source code.

  1. Open the AWS CodeBuild console at https://console.aws.amazon.com/codesuite/codebuild/home.

  2. On the navigation pane, choose Build projects, and then choose a project associated with a Bitbucket repository with webhooks. For information about creating a Bitbucket webhook project, see Step 1: Create a build project with Bitbucket and enable webhooks.

  3. Make some changes in the code in your project's Bitbucket repository.

  4. Create a pull request on your Bitbucket repository. For more information, see Making a pull request.

  5. On the Bitbucket webhooks page, choose View request to see a list of recent events.

  6. Choose View details to see details about the response returned by CodeBuild. It might look something like this: 

    "response":"Webhook received and build started: https://us-east-1.console.aws.amazon.com/codebuild/home..."
"statusCode":200

  7. Navigate to the Bitbucket pull request page to see the status of the build.
