Is there a way to set default context values for a flow? I'm wanting to put the endpoint to hit for API services into the context, and at the minute I'm entering this by hand every time I want to run from the UI. I guess ideally any prefect context values set when registering the flow would set them as defaults.

Hey @Matt Wong-Kemp afaik there isn’t a way to set the default prefect context in terms of flow run-based context. 🤔 Quick thought, is there a reason why you aren’t using Parameters for this? They allow for defaults and can be passed / accessible to all tasks

think it was mainly because I felt dependency-injecting the API endpoint into all tasks was going to be a pain - in a sense that the endpoint you hit is part of the environment

Ah I see, you could set default environment variables for your runs through the agent if you wanted to:

prefect agent start --env PREFECT__CONTEXT__MY_API="https..."

Can I set a context value to the value of a task? If so I could define my flow:

with Flow('foo') as flow:
    api = Parameter('endpoint')
    with prefect.context(endpoint=api):

It will not unfortunately 😕

that's fine, I can use it as a default and override on the ui

Good question actually, I would have to check but I think they are case sensitive

while you're there - do they get carried across correctly in the Kubernetes agent? suspect not as they don't appear to be in my environment in the k8s job it spawns

Ah wait that is actually a bug that has not been resolved! https://github.com/PrefectHQ/prefect/issues/2652

okay, I'll just pass by hand in the UI. +1 on that
