While registering the flow it is not storing the configs file which is present in a different directory. But some modules needs them. How to solve this?
Copy code
main-project
  | 
  src
     |
     | __init__.py
     | module1.py
     | module2.py
  |
  configs
     | 
     | config.yaml
  |
  flows
     |
     | sample_flow.py

Can you move code blocks to the thread?

I thought you would come back because the solution you posted in the other thread doesn't solve the problem of packaging flow code, it only sets credentials I can only give the same answer as here that you need to package this code including those config files into your Docker image - you would need:
Copy code
COPY configs/ /opt/prefect/configs/
r

@Anna Geller what storage should i use here? I am trying to print the flow file path when running in agent.
Copy code
@task
def print_cwd():
    logger = prefect.context.get("logger")
    <http://logger.info|logger.info>(os.getcwd())
    print(os.getcwd())

    <http://logger.info|logger.info>(os.path.dirname(__file__))
It is printing os.getcwd() value as
/app
. But somehow it is printing os.path.dirname as the path of the file in localsystem. So though I have configs folder present in /app/configs it is not able to read it and is looking at <localsystem_path>/configs.
Copy code

you could actually set this in your Dockerfile using the WORKDIR command. The default working directory is /opt/prefect if you leverage base Prefect image. What base image do you use? /app is used in Python base image usually

Copy code
FROM prefecthq/prefect:latest-python3.8
RUN apt-get update && apt-get install -y git && apt-get -y install gcc && apt-get install wget -y
COPY ./ /app
WORKDIR /app
COPY requirements.txt requirements.txt
RUN pip install -r requirements.txt --no-cache-dir
RUN pip install .

thanks. In that case to add configs you may do that explicitly using:
Copy code
COPY configs/ /app/configs/
r

Raviraja Ganta

05/05/2022, 7:02 PM
this will do that already.
COPY ./ /app
I added a task to print the items of dir /app
Copy code
['setup.py', 'config', 'mlinfra', 'tests', 'lambdas', 'notebooks', 'flows', 'iolib', 'dataprocessing', 'gpt', 'dockerfile', 'README.md', 'requirements.txt', 'taxonomy']
somehow the flow is printing path as
"/Users/raviraja/Desktop/python-monorepo/taxonomy/flows"
for this log statement
<http://logger.info|logger.info>(os.path.dirname(__file__))
.

probably an easier way of testing this would be to exec into the container and browse the file structure this way

the container does not contain flow code right? it should be fetched from storage dynamically whenever a flow is scheduled and the container dies once the flow is done right?

it depends on how you build the image - usually, no, your image doesn't need to contain your flow, this is what Storage is for
and yes, when the flow run finishes, the container finishes too
