Hello! I am trying Prefect2.0 for a simple flow from a docker container. I am getting an error and am stuck trying to resolve it - MissingContextError (“No settings context found”) Is there an explicit initial config required? Can I run flows from within a container? Any help would be really appreciated! Thanks!

This context should be initialized when prefect is imported.

I’m trying to create a flow on a request-response based system

Hey @R, do you have code you can share so we can get a better idea of what you’re trying to do?

Unfortunately I cannot share it. Could you please help me understand if I can manually initialise this context inside my Python code?

This works:

from prefect import flow, task
from prefect.context import get_run_context

@flow
def test():
    ctx = get_run_context()
    print(ctx.flow_run.expected_start_time)

test()

Is the flow function being called from a different thread than the thread or async context than where prefect is imported?

I tried importing inside the function where the flow is called

You could use

with prefect.context.use_profile("default"): …

This worked, thank you so much!

You need to point the API to the Orion API, and as long as it can connect, it should work

Could you please share an example for this?

It should be something like this. Specifially the API_URL for inside the Docker image.

Hey @Kevin Kho , thanks for sharing this. But I am not using any cloud provider. Can I run the UI on local host?

Yes you can on localhost. That is the default.

Is there a manual I can refer to for starting Orion from a docker-compose container and accessing UI from local host?

this is community contributed. maybe you can check it?

Thanks! Is there any possibility of official tutorials on this soon?

I think that is being taken and adopted with permission from the repo owner, so it’s in progress

Great, thank you so much
