Buildkite Dynamic Pipeline Steps Example

This repository is an example Buildkite pipeline that shows how to programmatically generate a build pipeline, allowing you to customize and distribute your build jobs however you wish.

How does it work?

When a build is start it runs a single job first. This job executes .buildkite/pipeline.sh | buildkite-agent pipeline upload.

This .buildkite/pipeline.sh script does the following:

• Creates a separate test step for each directory in specs
• Adds a deploy step at the end only if the build is on the master branch

For a non-master branch build it generates:

steps:
  - command: "specs/controllers/test.sh"
    label: "controllers"
  - command: "specs/features/test.sh"
    label: "features"
  - command: "specs/models/test.sh"
    label: "models"

For a master branch build it generates:

steps:
  - command: "specs/controllers/test.sh"
    label: "controllers"
  - command: "specs/features/test.sh"
    label: "features"
  - command: "specs/models/test.sh"
    label: "models"
  - wait
  - command: "echo Deploy!"
    label: ":rocket:"

What else could you do? The possibilities are endless. For example Jobsworth is a high-level tool that uses this to create deployments, rollbacks, QA steps, etc.
