upgrade alembic error

[mrk24251]

When running:
alembic upgrade head
in my ubuntu console.

I got this error:
Traceback (most recent call last):

I don't change my Dockerfile.

My docker file is:

FROM python:3.8

RUN mkdir app
WORKDIR app/

RUN apt update &&
apt install -y postgresql-client

COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt

COPY . .

You need to run it inside of the Docker image, where alembic and your project dependencies are installed. From the project README:

docker-compose run --rm backend alembic upgrade head

This will run alembic upgrade head from inside your backend container. You can also connect to the container directly and run any bash command by running:

docker-compose exec backend bash

That should open up an interactive bash prompt.

It is possible to run without docker, but you need to set vscode / pycharm to run python with PYTHONPATH=.
