hi folks, i have a question about agent-specific flow config. is there a way to make config available in a flow where the value will depend on the agent it's running in?

I don’t believe there is a way. What config are you trying to set? Maybe we can do it through a state handler?

our agents represent different regions, and we want to do things like connect to different databases depending on which region the flow is running in.

I understand, by agent config you don’t mean Prefect Automations right? I think for your use case, you can do:

prefect agent something start --env IDENTIFIER=value_here

and then in the Flow, you have access to that env variable

import os

@task
def mytask
    os.environ["IDENTIFIER"]

so the current plan is to use AWS Secrets Manager to manage the config for the different environments, but we were trying to find a nice way to get flows to look up the correct config based on the agent they're in

Yes putting it there starts the flow with that env variable

we tried setting environment in a YAML file and passing it in with

--task_definition

but that's not available to the flow, right?

that’s the env of the agent process. the --env sets a different environment variable on the agent that is looked at

got it, thanks!

This is the env var under the hood I think that is looked at to pass through

- name: PREFECT__CLOUD__AGENT__ENV_VARS
          value: '{"test": "test2"}'
