"""
Example Airflow DAG that displays interactions with Google Cloud Functions.
It creates a function and then deletes it.

This DAG relies on the following OS environment variables
https://airflow.apache.org/concepts.html#variables

* PROJECT_ID - Google Cloud Project to use for the Cloud Function.
* LOCATION - Google Cloud Functions region where the function should be
  created.
* ENTRYPOINT - Name of the executable function in the source code.
* and one of the below:

    * SOURCE_ARCHIVE_URL - Path to the zipped source in Google Cloud Storage

    * SOURCE_UPLOAD_URL - Generated upload URL for the zipped source and ZIP_PATH - Local path to
      the zipped source archive

    * SOURCE_REPOSITORY - The URL pointing to the hosted repository where the function
      is defined in a supported Cloud Source Repository URL format
      https://cloud.google.com/functions/docs/reference/rest/v1/projects.locations.functions#SourceRepository
