Tutorial: Use Git tags to start your pipeline - Amazon CodePipeline
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Tutorial: Use Git tags to start your pipeline

In this tutorial, you will create a pipeline that connects to your GitHub repository where the source action is configured for the Git tags trigger type. When a Git tag is created on a commit, your pipeline starts. This example shows you how to create a pipeline that allows filtering for tags based on the syntax of the tag name. For more information about filtering with glob patterns, see Working with glob patterns in syntax.

This tutorial connects to GitHub through the CodeStarSourceConnection action type.


The CodePipeline action for connections is not available in the China (Beijing) and China (Ningxia) Regions. To reference other available actions, see Product and service integrations with CodePipeline.


Before you begin, you must do the following:

  • Create a GitHub repository with your GitHub account.

  • Have your GitHub credentials ready. When you use the Amazon Web Services Management Console to set up a connection, you are asked to sign in with your GitHub credentials.

Step 1: Open CloudShell and clone your repository

You can use a command line interface to clone your repository, make commits, and add tags. This tutorial launches a CloudShell instance for the command line interface.

  1. Sign in to the Amazon Web Services Management Console.

  2. In the top navigation bar, choose the Amazon icon. The main page of the Amazon Web Services Management Console displays.

  3. In the top navigation bar, choose the Amazon CloudShell icon. CloudShell opens. Wait while the CloudShell environment is created.


    If you don't see the CloudShell icon, make sure that you're in a Region supported by CloudShell. This tutorial assumes you are in the US West (Oregon) Region.

  4. In GitHub, navigate to your repository. Choose Code, and then choose HTTPS. Copy the path. The address to clone your Git repository is copied to your clipboard.

  5. Run the following command to clone the repository.

    git clone https://github.com/<account>/MyGitHubRepo.git
  6. Enter your GitHub account Username and Password when prompted. For the Password entry, you must use a user-created token rather than your account password.

Step 2: Create a pipeline to trigger on Git tags

In this section, you create a pipeline with the following actions:

  • A source stage with a connection to your GitHub repository and action.

  • A build stage with an Amazon CodeBuild build action.

To create a pipeline with the wizard
  1. Sign in to the CodePipeline console at https://console.amazonaws.cn/codepipeline/.

  2. On the Welcome page, Getting started page, or Pipelines page, choose Create pipeline.

  3. In Step 1: Choose pipeline settings, in Pipeline name, enter MyGitHubTagsPipeline.

  4. In Pipeline type, keep the default selection at V2. Pipeline types differ in characteristics and price. For more information, see Pipeline types.

  5. In Service role, choose New service role.


    If you choose instead to use your existing CodePipeline service role, make sure that you have added the codestar-connections:UseConnection IAM permission to your service role policy. For instructions for the CodePipeline service role, see Add permissions to the the CodePipeline service role.

  6. Under Advanced settings, leave the defaults. In Artifact store, choose Default location to use the default artifact store, such as the Amazon S3 artifact bucket designated as the default, for your pipeline in the Region you selected for your pipeline.


    This is not the source bucket for your source code. This is the artifact store for your pipeline. A separate artifact store, such as an S3 bucket, is required for each pipeline.

    Choose Next.

  7. On the Step 2: Add source stage page, add a source stage:

    1. In Source provider, choose GitHub (Version 2).

    2. Under Connection, choose an existing connection or create a new one. To create or manage a connection for your GitHub source action, see GitHub connections.

    3. In Repository name, choose the name of your GitHub repository.

    4. Under Pipeline trigger, choose Git tags.

      In the Include field, enter release*.

      In Default branch, choose the branch that you want to specify when the pipeline is started manually or with a source event that is not a Git tag. If the source of the change is not the trigger or if a pipeline execution was started manually, then the change used will be the HEAD commit from the default branch.


      Pipelines that start with a trigger type of Git tags will be configured for WebhookV2 events and will not use the Webhook event (change detection on all push events) to start the pipeline.

    Choose Next.

  8. In Add build stage, add a build stage:

    1. In Build provider, choose Amazon CodeBuild. Allow Region to default to the pipeline Region.

    2. Choose Create project.

    3. In Project name, enter a name for this build project.

    4. In Environment image, choose Managed image. For Operating system, choose Ubuntu.

    5. For Runtime, choose Standard. For Image, choose aws/codebuild/standard:5.0.

    6. For Service role, choose New service role.


      Note the name of your CodeBuild service role. You will need the role name for the final step in this tutorial.

    7. Under Buildspec, for Build specifications, choose Insert build commands. Choose Switch to editor, and paste the following under Build commands.

      version: 0.2 #env: #variables: # key: "value" # key: "value" #parameter-store: # key: "value" # key: "value" #git-credential-helper: yes phases: install: #If you use the Ubuntu standard image 2.0 or later, you must specify runtime-versions. #If you specify runtime-versions and use an image other than Ubuntu standard image 2.0, the build fails. runtime-versions: nodejs: 12 #commands: # - command # - command #pre_build: #commands: # - command # - command build: commands: - #post_build: #commands: # - command # - command artifacts: files: - '*' # - location name: $(date +%Y-%m-%d) #discard-paths: yes #base-directory: location #cache: #paths: # - paths
    8. Choose Continue to CodePipeline. This returns to the CodePipeline console and creates a CodeBuild project that uses your build commands for configuration. The build project uses a service role to manage Amazon Web Service permissions. This step might take a couple of minutes.

    9. Choose Next.

  9. On the Step 4: Add deploy stage page, choose Skip deploy stage, and then accept the warning message by choosing Skip again. Choose Next.

  10. On Step 5: Review, choose Create pipeline.

Step 3: Tag your commits for release

After you create your pipeline and specify Git tags, you can tag commits in your GitHub repository. In these steps, you will tag a commit with the release-1 tag. Each commit in a Git repository must have a unique Git tag. When you choose the commit and tag it, this allows you to incorporate changes from different branches into your pipeline deployment. Note that the tag name release does not apply to the concept of a release in GitHub.

  1. Reference the copied commit IDs you want to tag. To view commits in each branch, in the CloudShell terminal, enter the following command to capture the commit IDs you want to tag:

    git log
  2. In the CloudShell terminal, enter the command to tag your commit and push it to origin. After you tag your commit, you use the git push command to push the tag to origin. In the following example, enter the following command to use the release-1 tag for the second commit with ID 49366bd. This tag will be filtered by the pipeline release* tag filter and will start the pipeline.

    git tag release-1 49366bd
    git push origin release-1
    Use the terminal to run the command to tag a commit.

Step 4: Release change and view logs

  1. After the pipeline runs successfully, on your successful build stage, choose View log.

    Under Logs, view the CodeBuild build output. The commands output the value of the entered variable.

  2. In the History page, view the Triggers column. View the trigger type GitTag : release-1.
