Prefect Community

Hi, maybe someone knows why it does not work for me. I'm trying to run simple flow (one flow with print) locally in manually built docker container and I get:
```root@3b776c4684ea:/prefect/jobs# python3 simple.py
Traceback (most recent call last):
  File "/usr/local/lib/python3.10/site-packages/asgi_lifespan/_concurrency/asyncio.py", line 17, in wait
    await self._event.wait()
  File "/usr/local/lib/python3.10/asyncio/locks.py", line 214, in wait
    await fut
asyncio.exceptions.CancelledError

During handling of the above exception, another exception occurred:```

dockerfile looks something like this:

```FROM python:3.10-bullseye

RUN apt-get update
RUN apt install sqlite3

run pip install prefect==2.0b5 prefect-snowflake==0.1.0```
plus ofcourse copying my sources, entrypoint etc

This looks like it’s related to the Python script you actually ran right?

yes,
```python3 simple.py```
:
```
from prefect import flow

@flow()
def myflow():
    print(["AAAA"] * 15)

    
if __name__ == "__main__":
    myflow()```


That’s pretty weird. Can you try with the prefect container instead?

sure, but probably tomorrow ...
where can I get the image or dockerfile ?

<https://hub.docker.com/r/prefecthq/prefect>
Maybe like `docker run prefecthq/prefect:2.0b5-python3.8`

similar problems using this image (I have copied my simple.py into container and run it with python3:
```root@1668c7681eb0:/opt/prefect# python3 simple.py
Traceback (most recent call last):
  File "/usr/local/lib/python3.8/site-packages/asgi_lifespan/_concurrency/asyncio.py", line 44, in run_and_fail_after
    await asyncio.wait_for(coroutine(), timeout=seconds)
  File "/usr/local/lib/python3.8/asyncio/tasks.py", line 501, in wait_for
    raise exceptions.TimeoutError()
asyncio.exceptions.TimeoutError```
so probably something wrong with my docker/ environment ?

locally (without docker) it works
```marcin@WSW-5M78J5J:/mnt/h/projects/prefect2.0$ python3 src/simple.py

It works in docker on native linux, so it's my env

ok, my wsl was using windows docker
was able to install docker on wsl without docker desktop and it helped
