NOTE: Minion is currently in a beta state, please report any issues in the issue tracker

Minion is a module for running database migrations located in the Kohana cascading filesystem, but it also provides a useful framework for creating cli based tasks.

The original "need" behind Minion was the lack of a good db migrations system, capable of selecting migrations from multiple locations (i.e. different modules).

The system is inspired by ruckusing, which had a nice system for defining tasks but lacked the desired flexibility.



Minion should be compatible with both Kohana 3.0.x and 3.1.x

Getting Started

First off, download and enable the module in your bootstrap

Then you can run minion like so:

php index.php --uri=minion/{task}

To view a list of minion tasks, run

php index.php --uri=minion/help

To view help for a specific minion task run

php index.php --uri=minion/help/{task}

For security reasons Minion will only run from the cli. Attempting to access it over http will cause a Kohana_Exception to be thrown.

Writing your own tasks

All minion tasks must be located in classes/minion/task/. They can be in any module, thus allowing you to ship custom minion tasks with your own module / product.

Each task must extend the abstract class Minion_Task and implement Minion_Task::execute().

See Minion_Task for more details.


Code should be commented well enough not to need documentation, and minion can extract a class' doccomment to use as documentation on the cli.


This module is unittested using the unittest module. You can use the minion group to only run minion tests.


phpunit --group minion

Feel free to contribute tests(!), they can be found in the tests/minion directory. :)

Can't I just create my own controllers instead of creating "tasks"

Yes, controllers offer just as much control as tasks, however there are a number of advantages to tasks:

  • They can only be run via command line or through code (see note about http)
  • All the groundwork for interacting with the user on the command line is already in place, you just need to take advantage of it
  • It provides a uniform way to access and perform tasks on the command line, rather than creating an elaborate collection of controllers while trying to restrict access to them. If you create a module that requires command line interaction then you just ship a minion task with it and users will be able to start using it with minimal setup & configuration

Eeew why aren't you using ORM xyz?

In order to prevent conflicts across installations Minion aims to have as few dependencies as possible.

This is awesome! How can I contribute?

Thanks for wanting to help out, just fork, commit, push, and send a pull request :)


Sorry you feel that way, it'd be useful if you could create an issue outlining what you think should be changed.
