Version 0.2.0
Repository https://github.com/chaostoolkit-incubator/chaostoolkit-gandi

Build Status Python versions

This project is a collection of actions and probes, gathered as an extension to the Chaos Toolkit.

Install

This package requires Python 3.5+

To be used from your experiment, this package must be installed in the Python environment where chaostoolkit already lives.

$ pip install -U chaostoolkit-gandi

Usage

To use the probes and actions from this package, add the following to your experiment file:

    "version": "1.0.0",
    "title": "Our domains are not going expiring within a month",
    "description": "We need time to renew.",

                            "when": "1 month"
                        }
                    }

                    "func": "list_domains"
                }
            }
        ]
    },
    "method": []
}

That’s it!

Set the GANDI_API_KEY environment variable to your Gandi API Key.

Please explore the code to see existing probes and actions.

Contribute

If you wish to contribute more functions to this package, you are more than welcome to do so. Please, fork this project, make your changes following the usual PEP 8 code style, sprinkling with tests and submit a PR for review.

The Chaos Toolkit projects require all contributors must sign a Developer Certificate of Origin on each commit they would like to merge into the master branch of the repository. Please, make sure you can abide by the rules of the DCO before submitting a PR.

Develop

If you wish to develop on this project, make sure to install the development dependencies. But first, create a virtual environment and then install those dependencies.

$ pip install -r requirements-dev.txt -r requirements.txt

Then, point your environment to this directory:

$ pip install -e .

Now, you can edit the files and they will be automatically be seen by your environment, even when running from the chaos command locally.

Test

To run the tests for the project execute the following:

$ pytest

Exported Activities

domains

domains_should_not_expire_in
Type tolerance
Module chaosgandi.domains.tolerances
Name domains_should_not_expire_in
Return boolean

Go through the list of Gandi domains and fails if any expires before the given date threshold as a relative time to now.

Signature:

def domains_should_not_expire_in(value: List[Dict[str, Any]] = None,
                                 when: str = '1 month') -> bool:
    pass

Arguments:

Name Type Default Required
value list null No
when string “1 month” No

Tolerances declare the value argument which is automatically injected by Chaos Toolkit as the output of the probe they are evaluating.
