Question

Hello everybody! This is my Dockerfile: from python:3.12.2-slim-bullseye as dev workdir /app copy

--from=builder /usr/local/lib/python3.12/site-packages /usr/local/lib/python3.12/site-packages
copy src/ .
cmd python -u bot.py
why if I add into my docker-compose:
volumes:
- ./app:/app
it says in the log:
python: can't open file '/app/bot.py': [Errno 2] No such file or directory
? Thank you!
