Hello, Does anyone if prefect can provide this? I have a flow running in Deployment A and there are additional flows in deployment B. I need to verify if the flow in deployment A is successfully ran (in the scheduled time) to kick-off flows in Deployment B. I tried searching in documents but couldn't find anything helpful. Can anyone please guide me if this is possible or share the related document?

Not out of the box. But you can use the prefect python client OR api to code the functionality you want on Deployment B flow run.

hi @Mohan kancherla - there's a few ways to go about this - 2 common patterns are: • events, if you're on prefect cloud. you can create an automation to

Run a Deployment

when you see a

prefect.flow-run.Completed

event that has your

Deployment A

as a related resource • you can have a parent flow that orchestrates the deployments

from prefect.deployments import run_deployment

@flow
def parent():
    A = run_deployment("flow-a/deployment-a")
    if A.state.is_completed():
       B = run_deployment("flow-b/deployment-b")

I like the approach 2 and does it also accepts the environmental variables(parameters) to the flow, in the run deployment?

you can pass

parameters

to

run_deployment

, which should be a dictionary of the parameters that the flow run accepts (must be JSON serializable!)

Thank you

Ah my interpretation of

in the scheduled time

was that they were not late 😄
