bksr

bksr - Buildkite Step Runner

Run and test your Buildkite pipeline steps locally, just as they'd run in CI, using the buildkite-agent bootstrap itself.

$ bksr
? Choose a pipeline step to run (Use arrow keys)
❯ :shell: Shellcheck
  :sparkles: Lint
  :shell: Tests

Features:

• Runs any Buildkite command pipeline step, including those that use plugins
• Won’t accidentally run steps designed for branches (such as 'master' only release steps)
• Can run dynamic pipelines via STDIN
• Can run all steps in sequence, including specifying a branch for branch filtering
• Can run a fresh checkout, emulating a clean CI agent environment

Installation

On macOS using Homebrew:

$ brew install toolmantim/bksr/bksr

Everywhere else:

$ npm i -g bksr

Or, with npx

$ npx bksr

Or, like srsly:

$ alias bksrsly=bksr
$ bksrsly
? Choose a pipeline step to run (Use arrow keys)
❯ :shell: Shellcheck
  :sparkles: Lint
  :shell: Tests

Requirements

• buildkite-agent v3+

Roadmap

Small stuff

• Fix examples not showing in --help
• Homebrew

Bigger stuff

• Support env var substituion in pipeline.yml (buildkite/agent#765)
• Support setting env vars based on pipeline.yml
• Hide build output via header collapsing
• Local-mode artifact/metadata/pipeline commands
• Bundling the buildkite-agent binary maybe?

Developing

You can run it locally by invoking lib/bksr.js from the command line:

$ cd ~/some-project
$ ~/path-to-bksr-checkout/bin/bksrc.js

To run the unit and integration tests:

$ docker-compose run --rm tests

Or, you can use bksr itself 😱

$ bin/bksr.js --all

Releasing

The following command will:

• Ensure you’re on master
• Update the version number in package.json
• Create and push the git tag
• Open GitHub releases so you can fill out release notes, and open previous releases so you can copy+pasta

git checkout master && git pull && npm version [major | minor | patch]
