Help needed in Docker build

Hi Folks,

I am pretty novice in Docker and have just started. However I am planning to build Docker Image using Dockerfile but this is failing at below point and stating the it could not copy the file.

However I see the file is present in directory it should
have been copied in docker image. Any clue or help is much appreciated to eliminate the cause.

Running hooks in /etc/ca-certificates/update.d...

Step 6/9 : RUN cd /opt/honeysap &&     python install &&     rm -rf /tmp/* /var/tmp/*
 ---> Running in 6a7cd3e86d91
python: can't open file '': [Errno 2] No such file or directory
The command '/bin/sh -c cd /opt/honeysap &&     python install &&     rm -rf /tmp/* /var/tmp/*' returned a non-zero code: 2

And here is my Dockerfile

FROM ubuntu:18.04


# Install system packages
RUN apt-get update && apt-get install -y \
        git \
        python-pip \
        python-dev \
        build-essential && \
    apt-get clean && \
    rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

COPY . /opt/honeysap
WORKDIR /opt/honeysap

# Clone git repo and install HoneySAP
RUN cd /opt/honeysap && \
    python install && \
    rm -rf /tmp/* /var/tmp/*

# Install extra python packages
RUN pip install -r requirements-optional.txt

EXPOSE 3299 8001

CMD ["/usr/local/bin/honeysap", "--config-file", "honeysap.yml"]

OK - I got it resolved since it does not have directory in the path it wasnt copying.
