Prefect 2.8.6 has been released! Prefect Runtime For Context Access Many users of Prefect run their flows in highly dynamic environments; because of this it can be incredibly useful to access information about the current flow run or deployment run outside of a flow function for configuration purposes. For example, if we are running a Prefect deployment within a larger Dask cluster, we might want to use each flow run id as the Dask client name for easier searching of the scheduler logs. Prefect now offers a user-friendly way of accessing this information through the

prefect.runtime

namespace:

from prefect.runtime import flow_run
from prefect import flow
from prefect_dask.task_runners import DaskTaskRunner

@flow(task_runner=DaskTaskRunner(client_kwargs = {"name": flow_run.id}))
def my_flow():
    ...

This will create a Dask client whose name mirrors the flow run ID. Similarly, you can use

prefect.runtime

to access parameters that were passed to this deployment run via

prefect.runtime.deployment.parameters

. Note that all of these attributes will be empty if they are not available. See #8790 for details. A few other key enhancements and fixes: Enhancements • Add deployment ID support to
