Dockerfile-python：无法打开文件'/usr/app/client.py'：[Errno 2]没有这样的文件或目录

Question

I have the following Dockerfile...

FROM python:2.7.15

RUN mkdir /usr/app
WORKDIR /usr/app
COPY ./app/requirements.txt .
RUN pip install --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.2.1-cp27-none-linux_x86_64.whl && pip install -r requirements.txt

ADD app/* /

ENV PYTHONUNBUFFERED 1

CMD ["python", "/usr/app/client.py"]

Which will build but will not run because of python file. I have tried...

client.py

and

./client.py

None of this works. Am I missing something? The ADD should be adding this file along with other python scripts

Answer 1

Assuming that you have downloaded the coding files, make sure that your terminal is in the same directory as the file you want to open.

eg If code.py is in the folder /Downloads/Python

Then run cd /Downloads/Python to change directory (cd) before you start.

Then you should be able to type your command as:

$: /Downloads/Python> python code.py

(or similar, depending on your os)
