Include local folder in Docker container-CodePudding

I have this structure:

ROOT
|
|--my_module
    | __init__.py
    | my_file.py
| Dockerfile
| app.py

Inside app.py is from my_module import my_file which is triggering a "errorMessage": "Unable to import module 'app': No module named 'my_module'", which a) feels like a backwards error message to me, so maybe I'm misunderstanding, and b) I can't fix.

I've gone into the command line and seen that indeed, my_module is not included. I've tried adding the following to my Dockerfile (separately):

COPY app.py requirements.txt my_module/ ./ and COPY my_module/ /usr/lib/python3.8/my_module/

But no help, although the latter does at least include the my_module folder in the /usr directory. Same error though, when I use it in the AWS console. When I directly run the file in Docker, I get the similar error message of:

Traceback (most recent call last):
  File "app.py", line 14, in <module>
    from my_module import my_file
ModuleNotFoundError: No module named 'my_module'

Try something like this:

RUN mkdir -p my_module
COPY app.py requirements.txt ./
COPY my_module/* my_module/

You need to mount the volume, see: https://docs.docker.com/storage/volumes/

Within your docker-compose file it would look something like this: version: "3.9" services: web: volumes: - root:/home/yourapp volumes: yourapp:
