prefect.runtime.flow_run

Access attributes of the current flow run dynamically.

Note that if a flow run cannot be discovered, all attributes will return empty values.

You can mock the runtime attributes for testing purposes by setting environment variables prefixed with PREFECT__RUNTIME__FLOW_RUN.

Available attributes
  • id: the flow run's unique ID
  • tags: the flow run's set of tags
  • scheduled_start_time: the flow run's expected scheduled start time; defaults to now if not present
