🐱 Catlin 🐱

Catlin is a command-line tool that Lints Tekton Resources and Catalogs.

It validates the resources on the basis the Tekton catalog structure defined in the TEP.

Commands

Validate

This command validates

• If the resource is in valid path
• If the resource is a valid Tekton Resource
• If all mandatory fields are added to the resource file
• If all images used in Task Spec are tagged
• If platforms are specified in correct format

catlin validate <path-to-resource-file>

Bump

This command bumps the version of an existing resource in the catalog. After running this command a new version of the given resource will be created in its own directory and the latest version of that resource will be copied into it, ready for editing.

catlin bump <path-to-resource-directory>

This example bumps the version of git-clone:

$ catlin bump task/git-clone
Copying task/git-clone/0.5 to task/git-clone/0.6

As a pre-commit hook

Catlin may be run as a pre-commit hook.

As an example .pre-commit-config.yaml:

repos:
  - repo: https://github.com/tektoncd/catlin
    rev: main
    hooks:
      - id: catlin
        args:
          - validate
        files: <REGEX of resource files>

Installing the above pre-commit configuration with pre-commit install will automatically run the validate command on each commit to your resource repository.
