gordon-gcp: GCP Plugins for Gordon and Gordon Janitor

Event-driven Cloud DNS and DNS Reconciliation Services

Google Cloud Platform (GCP) plugins for gordon, an open-source, event-driven service for 3rd party DNS providers, and for gordon-janitor, an open-source service that checks Cloud DNS records against a source of truth (e.g. Compute Engine) and submits corrections to gordon via Google Pubsub.

The gordon-gcp plugins add optional support for the following:

Service:

• Consuming events from Google Cloud Pub/Sub
• Reading from Google Compute Engine for record information
• Creating, updating, and deleting records within Google Cloud DNS

Janitor:

• Reading instance lists from Google Compute Engine
• Comparing record sets from Google Compute Engine and Google Cloud DNS
• Publishing any required DNS changes to Google Cloud Pub/Sub

NOTICE: This is still in the planning phase and under active development. Gordon, Gordon Janitor, and these plugins should not be used in production yet.

Requirements

• Python 3.6
• Google Cloud Platform account
• Service account JSON key that has relevant access (i.e. read and/or write) to the plugin service you want to use (e.g. Google Cloud DNS, Pub/Sub, or Compute Engine). See Google's documentation on how to create a key.

Support for other Python versions may be added in the future.

Development

For development and running tests, your system must have all supported versions of Python installed. We suggest using pyenv.

Setup

$ git clone [email protected]:spotify/gordon-gcp.git && cd gordon-gcp
# make a virtualenv
(env) $ pip install -r dev-requirements.txt

Running tests

To run the entire test suite:

# outside of the virtualenv
# if tox is not yet installed
$ pip install tox
$ tox

If you want to run the test suite for a specific version of Python:

# outside of the virtualenv
$ tox -e py36

To run an individual test, call pytest directly:

# inside virtualenv
(env) $ pytest tests/test_foo.py

Build docs

To generate documentation:

(env) $ pip install -r docs-requirements.txt
(env) $ cd docs && make html  # builds HTML files into _build/html/
(env) $ cd _build/html
(env) $ python -m http.server $PORT

Then navigate to localhost:$PORT!

To watch for changes and automatically reload in the browser:

(env) $ cd docs
(env) $ make livehtml  # default port 8888
# to change port
(env) $ make livehtml PORT=8080
