Python code obfuscation in Docker image/container

Question

i'm trying to build docker image with python in it in obfuscated form, so i tried below method

    FROM ubuntu:bionic

ENV DEBIAN_FRONTEND=noninteractive

RUN apt-get update \
  && apt-get install -y python3-pip python3-dev \
  && cd /usr/local/bin \
  && ln -s /usr/bin/python3 python \
  && pip3 install --upgrade pip

COPY hello-world.py /
COPY requirments.txt /
RUN pip install -r requirments.txt
RUN pyarmor obfuscate 'hello-world.py'
RUN rm -rf hello-world.py
RUN cd dist
CMD ["python", "hello-world.py"]

i'm getting error at pyarmor command

INFO     Start obfuscating the scripts...
INFO        ello-world.py -> dist/ello-world.py
ERROR    [Errno 2] No such file or directory: '/ello-world.py'

need some help

Putting the original file outside of the root (/) seems to have fixed the issue:

FROM ubuntu:bionic

ENV DEBIAN_FRONTEND=noninteractive

RUN apt-get update \
  && apt-get install -y python3-pip python3-dev \
  && cd /usr/local/bin \
  && ln -s /usr/bin/python3 python \
  && pip3 install --upgrade pip

WORKDIR /app
COPY hello-world.py .
COPY requirements.txt .
RUN pip install -r requirements.txt
RUN pyarmor obfuscate hello-world.py
RUN rm -rf hello-world.py
CMD ["python", "dist/hello-world.py"]

docker build -t obf-hello .
... <output omitted> ...

docker run -it --rm obf-hello
HELLO WORLD!
