The error "ModuleNotFoundError: No module named 'app'" suggests that the Python interpreter cannot find the 'app' module. This issue might be related to the system path configuration in your Docker environment.

Here are a few steps to resolve this:

1. Check the WORKDIR in Dockerfile: Ensure that the WORKDIR in your Dockerfile is set correctly. It should be set to the directory where the 'app' module is located. According to the Dockerfile, it should be /app ^[1].

2. Verify the PYTHONPATH: Make sure that the directory containing the 'app' module is included in the PYTHONPATH. You can set this in your Dockerfile or docker-compose.yml by adding an environment variable:

   ENV PYTHONPATH=/app

3. Check the env.py Configuration: The env.py file in the migrations directory modifies the system path to import the 'app' module by appending the parent directory to the system path ^[2]. Ensure this configuration is correct and that the path is being set as expected.

4. Build Context in docker-compose.yml: Ensure that the build context in your docker-compose.yml is set correctly. The context should include the directory where the 'app' module resides. For example, the server service should have a context like ./server if the 'app' module is within the server directory ^[3].

By verifying these configurations, you should be able to resolve the module not found error.
