A linter for your Buildkite plugins, used by the plugin-linter Buildkite plugin ✨

Features:

• Checks for a plugin.yml file (and validates it against the plugin.yml JSON schema)
• Checks that all readme examples match the plugin’s schema
• Check the readme version numbers are up-to-date with the latest plugin version
• Machine-parseable TAP output

Further reading and tools:

• JSON Schema
• JSON Schema Lint

You can use this tool via the Linter Plugin or you can add it to your docker-compose.yml file and then use docker-compose run --rm lint:

services:
  lint:
    image: buildkite/plugin-linter
    command: ['--id', 'my-org/my-plugin']
    volumes:
      - ".:/plugin"

or you can run it locally on the command line:

docker run \
  -it \
  --rm \
  -v "$(pwd):/plugin" \
  buildkite/plugin-linter \
    --id my-org/my-plugin

If your plugin examples use a full git URL, such as ssh://[email protected]/my-org/example-buildkite-plugin, then you should specify the full git URL in the id argument.

• Check that all the config options in the readme exist in the configuration schema
• Check that all the options in the configuration schema exist in the readme
• Warn about undocumented config options found in source code
