What is the best method for having a flow kick-off after every successful completion of another flow which is scheduled every 15 mins? I haven't found documentation for this but if there are docs for it that would be helpful

Hey! You can

run_deployment()

inside of your flow run, maybe inside of the

on_completion

hook. here is a general example for how to use run deployment. Additionally if you're using Prefect Cloud, use can use automations, where you can trigger a flow to kick off after every success.

@Jake Kaplan I am trying to implement your suggestion and just need a bit more clarification; I am trying to have each of my flows in the list execute sequentially upon successful completion of the main flow. See screenshots. It looks like I need to pass in the main flow state to the start_other_flows() function somehow, can you help me understand how to do this?

I don't believe you need

@task

around

start_other_flows

it should just be a callable

You're right, and turns out I need to pass in variables from the event hook so I changed the function to this and it worked. Thank you!
