@Marvin How do I use the serve method to schedule my flow to run at 7am each day?

In Prefect, using the
.serve
method can effectively schedule your workflows. You would typically use it after defining your flow, something like this:
Copy code
python
from prefect import flow

@flow
def my_flow():
    # Your flow's tasks and logic here

if __name__ == "__main__":
    my_flow.serve(name="my_flow_deployment", schedule=<YOUR SCHEDULE HERE>)
For scheduling your flow to run daily at 7am, you need to define a schedule object that specifies this requirement and pass it to the
.serve
method. Here's an example of how you might accomplish a daily schedule at 7am:
Copy code
python
from prefect import flow
from prefect.orion.schemas.schedules import IntervalSchedule
from datetime import timedelta, time

@flow
def my_flow():
    # Your flow's tasks and logic here

schedule = IntervalSchedule(interval=timedelta(days=1), start_time=time(7))

if __name__ == "__main__":
    my_flow.serve(name="my_daily_7am_flow", schedule=schedule)
In this snippet, the
IntervalSchedule
is used to define that the interval is 1 day and the start_time is set to
time(7)
, indicating 7 am. This will ensure that your flow runs every day at 7 am. Please note that the exact syntax and available functions for scheduling may vary based on the Prefect version you are using. Always refer to the official Prefect documentation for the most accurate and up-to-date instructions.
