How to correctly specify the path to the folder, for use in docker?

Question

Python

when running the image, docker throws an error

File "/usr/src/app/./index.py", line 26, in handle_text
    photo = open('test/' + random.choice(os.listdir('test')), 'rb')
FileNotFoundError: [Errno 2] No such file or directory: 'test'

the docker file itself

FROM python:3-alpine
WORKDIR /usr/src/app
LABEL version="1.0"
COPY /* ./
RUN pip install -r requirements.txt
CMD [ "python", "./index.py" ]

using test folder in script

if message.text.lower() == 'получить вопрос':
        photo = open('test/' + random.choice(os.listdir('test')), 'rb')

how to fix this error?

Answer 1

it was necessary to specify in docerfile
COPY ./ ./
instead of
COPY /* ./
