Example Code

I made a few adjustments to the project structure since I only need the backend because I don't need the frontend. the attached image is my fastAPI project structure.

I followed the documentation and I was able to spin  up the docker container, but when I run `bash /start-reload.sh` in my docker exec, I got this error
`/app/prestart.sh: line 2: $'\r': command not found`

I got the latest version and tested it, no problems.
Looking at the example you gave, the error "/app/prestart.sh: line 2: $'\r': command not found" occurs. Have you checked the prestart.sh file?

#! /usr/bin/env bash

# Let the DB start
python /app/app/backend_pre_start.py

#Runmigrations
alembic upgrade head

# Create initial data in DB
python /app/app/initial_data.py

I think your prestart.sh should be like above, but there seems to be a problem. Have you modified anything?

[realsbd]

yes, my prestart.sh looks like this #! /usr/bin/env bash # Let the DB start python /app/app/backend_pre_start.py # Run migrations alembic upgrade head # Create initial data in DB python /app/app/initial_data.py I don't know if docker will run on another python version but my PC version is 3.11 <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free.www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

I can't configure the environment so that an error like yours occurs.
First of all, what I'm curious about is: Have you searched for why the \r error occurs?

In Windows, we confirmed that \r\n is added due to CRLF when editing with an editor.

I offer you two solutions.

1. Modify and test the file to prevent CRLF problems from occurring.
2. Delete all currently cloned git data (folders), receive a new clone, and test.

And if you did docker compose normally, I think python3.10.14 version would have been installed in the container.

I will try again with a fresh clone <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free.www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
