A full list of available plugins can be found here. Generally one repo is made per plugin with related operators and hooks are grouped together in one plugin when possible.
Tutorials can be found in the Tutorials folder. Example tutorials currently available include:
Because Google Cloud Platform's authentication requires a keyfile for a service account, accessing tools like BigQuery from a containerized environment (without persistent local storage) can be somewhat complex. The GCP Base Hook solves this in Airflow 1.9 by allowing the contents of the keyfile to be put in an Airflow connection object but, for those still using 1.8 and lower, we've put together a quick tutorial on how to used modified hooks as a workaround.
If you have a plugin that you've built or nefariously acquired (no judgement), we'd be more than happy to have it added to the org. General guidelines for how to get your plugin into shape can be found here.
All example DAGs that use the plugins can be found in the Example Airflow DAGs repo.
