Airflow v2.x

Currently, allows configuring dags to be loaded from

  • GCS bucket
  • Local filesystem
  • inmemory

Implementation already supports variety of other systems, just need to configure them.

For using a fs that needs auth, it is required to create a project secret with STORAGE as key and base64 encoded service account/token as value.

Optimus also provides api to get currently running job status using airflow APIs. For this to work, it is required to register a secret with SCHEDULER_AUTH as key and base64 encoded username:password as token. This assumes airflow is configured to use basic auth on api by default.
