so I have my flow in one file and then the tasks in another file. I finally got them to play nicely with Docker storage, but now in the RUN python /opt/prefect/healthcheck.py, it can't find the file that is in the same folder as the flow.

System Version check: OK
/opt/prefect/healthcheck.py:130: UserWarning: Flow uses module which is not importable. Refer to documentation on how to import custom modules <https://docs.prefect.io/api/latest/storage.html#docker>
  flows = cloudpickle_deserialization_check(flow_file_paths)
Traceback (most recent call last):
  File "/opt/prefect/healthcheck.py", line 130, in <module>
    flows = cloudpickle_deserialization_check(flow_file_paths)
  File "/opt/prefect/healthcheck.py", line 43, in cloudpickle_deserialization_check
    flows.append(cloudpickle.loads(flow_bytes))
ModuleNotFoundError: No module named "Module"

Did you build this image beforehand or do you intend for DockerStorage to build it?

Build this image beforehand.

When you register then, you can do

flow.register(build=False)

Sweet. I will try that.

This is a similar thread. He just moved his traceback to the end

Wait can you explain that?

There is an example in the thread with William.

LocalStorage

will look for the file relative to the container
