Trigger Buildkite Pipeline GitHub Action

A GitHub Action for triggering a build on a Buildkite pipeline.

Features

• Creates builds in Buildkite pipelines, setting commit, branch, message.
• Provides the build JSON response and the build URL as outputs for downstream actions.

Usage

Create a Buildkite API Access Token with write_builds scope, and save it to your GitHub repository’s Settings → Secrets. Then you can configure your Actions workflow with the details of the pipeline to be triggered, and the settings for the build.

Configuration Options

Configuration as Input Parameters

The following workflow creates a new Buildkite build to the target pipeline on every commit.

on: [push]

steps:
  - name: Trigger a Buildkite Build
    uses: "buildkite/[email protected]"
    with:
      buildkite_api_access_token: ${{ secrets.TRIGGER_BK_BUILD_TOKEN }} 
      pipeline: "my-org/my-deploy-pipeline"
      branch: "master"
      commit: "HEAD"
      message:  ":github: Triggered from a GitHub Action"
      build_env_vars: '{"TRIGGERED_FROM_GHA": "true"}'
      build_meta_data: '{"FOO": "bar"}'
      ignore_pipeline_branch_filter: true     
      send_pull_request: true

Outputs

The following outputs are provided by the action:

Output var	Description
url	The URL of the Buildkite build.
json	The JSON response returned by the Buildkite API.

Development

To run the test workflow, you use act which will run it just as it does on GitHub:

act -n

Testing

To run the tests locally, use the plugin tester (that has everything already installed) by running the Docker command

docker run --rm -ti -v "$PWD":/plugin buildkite/plugin-tester:v4.0.0

Contributing

• Fork this repository
• Create a new branch for your work
• Push up any changes to your branch, and open a pull request. Don't feel it needs to be perfect — incomplete work is totally fine. We'd love to help get it ready for merging.

Releasing

• Create a new GitHub release. The version numbers in the readme will be automatically updated.

Roadmap

• Add a WAIT option for waiting for the Buildkite build to finish.
• Support other properties available in the Buildkite Builds REST API, such as environment variables and meta-data.

Contributions welcome! ❤️
