Hi, I have a flow that I want to trigger based on other flows using

@trigger_on_finish

. The flows that I want to base the trigger on can change so I would like to specify the flow using a command line argument (or some other way of supplying arguments). Basically I want to do something like this

parser = parser = argparse.ArgumentParser()
parser.add_argument("--flow")
args = parser.parse_args()

@trigger_on_finish(flow=args.flow)
class MyFlow(FlowSpec):
    @step
    def some_step(self)

I am deploying the pipelines to Airflow so I don't think I can use

Runner

to specify these arguments. When trying to run

python my_flow.py --flow flow_one airflow create my_dag.py

I get

error: unrecognized arguments: airflow create my_dag.py

Is there a way to specify arguments to flow decorators from outside of the python script?

configs should do it: https://docs.metaflow.org/metaflow/configuring-flows/basic-configuration#accessing-config-keys

Ah perfect! Thank you!
