Buildkite Migration tool

A tool to help kick start the transition of pipelines from other CI providers to Buildkite.

$ buildkite-compat examples/circleci/legacy.yml
---
steps:
- commands:
  - "# No need for checkout, the agent takes care of that"
  - pip install -r requirements/dev.txt
  plugins:
  - docker#v5.7.0:
      image: circleci/python:3.6.2-stretch-browsers
  agents:
    executor_type: docker
  key: build

Note: Setting the environment variable BUILDKITE_PLUGIN_<UPPERCASE_NAME>_VERSION will override the default version of the plugins used. For example:

$ BUILDKITE_PLUGIN_DOCKER_VERSION=testing-branch buildkite-compat examples/circleci/legacy.yml
---
steps:
- commands:
  - "# No need for checkout, the agent takes care of that"
  - pip install -r requirements/dev.txt
  plugins:
  - docker#testing-branch:
      image: circleci/python:3.6.2-stretch-browsers
  agents:
    executor_type: docker
  key: build

Web Service/API

Buildkite Compat can also be used via a HTTP API using rackup from the app folder of this repository.

You start the web UI with either of the following docker commands:

docker compose up webui

Note: If you are using docker run you will have to override the entrypoint:

$ docker run --rm -ti -p 9292:9292 --entrypoint '' --workdir /app $IMAGE:$TAG rackup --port 9292

After that, you can access a simple web interface at http://localhost:9292

You can also programatically interact with it (maybe even pipe the output directly to buildkite-agent pipeline upload!):

$ curl -X POST -F 'file=@app/examples/circleci/legacy.yml' http://localhost:9292

Translation results

Buildkite has its own suggested best practices, these may differ to those from other providers, check out the Buildkite Docs for more information. Review and use the results of this tool as the basis towards Buildkite adoption, the output of the migration tool is a guide and manual editing is likely to be required.
