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.

For example, the following workflow creates a new Buildkite build on every commit:

workflow "Trigger a Buildkite Build" {
  on = "push"
  resolves = ["Build"]
}

action "Build" {
  uses = "buildkite/trigger-pipeline-action@v1.2.0"
  secrets = ["BUILDKITE_API_ACCESS_TOKEN"]
  env = {
    PIPELINE = "my-org/my-deploy-pipeline"
    COMMIT = "HEAD"
    BRANCH = "master"
    MESSAGE = ":github: Triggered from a GitHub Action"
  }
}

Configuration Options

The following environment variable options can be configured:

Env var	Description	Default
PIPELINE	The pipline to create a build on, in the format <org-slug>/<pipeline-slug>
COMMIT	The commit SHA of the build. Optional.	$GITHUB_SHA
BRANCH	The branch of the build. Optional.	$GITHUB_REF
MESSAGE	The message for the build. Optional.
BUILD_ENV_VARS	Additional environment variables to set on the build, in JSON format. e.g. {"FOO": "bar"}. Optional.

Outputs

The following outputs are provided by the action:

Output var	Description
url	The URL of the Buildkite build.
apiUrl	The api endpoint 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:

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.
