This GitHub Actions will help you trigger a pipeline in your AWS CodePipeline - assumming you already have the pipeline. This will not create the pipeline for you.

Create an IAM user with codepipeline:StartPipelineExecution permission. You may take and customize the IAM policy below as starter point. Note that I'm using "*" in the policy. For better security, you can limit the policy to only execute specific pipelines. You can read more about IAM for CodePipeline here.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "codepipeline:StartPipelineExecution"
            ],
            "Resource": [
                "*"
            ]
        }
    ]
}

After you create the IAM user with the right permission, add two variables below in your GitHub repository secrets area:

• AWS_PIPELINE_ACCESS_KEY: the Access Key ID for the user that you just created
• AWS_PIPELINE_SECRET_KEY: the Secret Key for the user that you just created

Note:

• Please check the latest available version here and replace it with X.X.X in the code examples below.

• Identify in which AWS region your pipeline is located. Use that region name for aws-region key below. AWS regions list is available here.

jobs:
  deploy:
    steps:
      - name: Trigger AWS CodePipeline
        uses: zulhfreelancer/[email protected]
        with:
          aws-region: "ap-southeast-1"
          aws-access-key: ${{ secrets.AWS_PIPELINE_ACCESS_KEY }}
          aws-secret-key: ${{ secrets.AWS_PIPELINE_SECRET_KEY }}
          pipeline-name: "your-pipeline-name"

Below is the example for situation where:

• You only want to trigger the pipeline if previous job was successful
• You only want to trigger the pipeline if the Git branch that GitHub Actions currently running is a specific branch

jobs:
  job1:
    ... code for job1 ...
  deploy:
    needs: job1
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Trigger AWS CodePipeline
        uses: zulhfreelancer/[email protected]
        if: github.ref == 'refs/heads/your-branch-name'
        with:
          aws-region: "ap-southeast-1"
          aws-access-key: ${{ secrets.AWS_PIPELINE_ACCESS_KEY }}
          aws-secret-key: ${{ secrets.AWS_PIPELINE_SECRET_KEY }}
          pipeline-name: "your-pipeline-name"
