Hi all 🙂 I am experimenting with a setup running the prefect-server in kubernetes, and having another container run an agent. But before running this agent, using

prefect agent start -q 'foo'

for example, I’d like to create and apply deployments using the

Deployment.build_from_flow

syntax described here https://docs.prefect.io/concepts/deployments/#create-a-deployment-from-a-python-object . Then I want this python script to run before I start the agent…

from prefect.deployments import Deployment
from flows.deployments.example_script import flow_name


deployment = Deployment.build_from_flow(
    flow=flow_name,
    name="Test",
    work_queue_name="test",
)

deployment.apply()

I’ve tried running it standalone and in Docker but I get a Attribute Error

module 'flows.deployments.example_script.flow_name' has no attribute 'name'

If I use

setattr(flow_name, 'name', 'something)'

before the definition of

deployment

then I don’t get this exact error but this

ValueError: Could not determine flow's file location.

I’m unsure of where to begin and would love any sort of help

What does your example_script look like?

I import a bunch of functions from other project modules and encapsule some in

@task()

decorators, and use these in one function encapsulated by

@flow()

I don't know what you're doing wrong, since you're not providing much evidence you do everything right. This is working for me. File structure is this:

.

├── deploy.py

└── flows

├── __init__.py

└── deployments

├── __init__.py

└── example_script.py

deploy.py contains the same code as you gave above, example_script looks like this:

from prefect import task, flow

@task

def function_one():

pass

@task

def function_two():

pass

@flow

def flow_name():

function_one()

function_two()

Hi @Mathijs Carlu, thanks for your help, I’ve found the problem, I was passing the module instead of the function, stupid me. I’ve been trying to debug this for longer than I want to admit 🥵
