Reduce image size by removing *.pyc + wheels from the image

[pmav99]

You could reduce the image size by removing *.pyc + wheels from the image. E.g. something like this:

# Install ansible + dependencies.
RUN apt-get update \
 && apt-get install -y --no-install-recommends \
       apt-utils \
       python-setuptools \
       python-pip \
       software-properties-common \
       rsyslog systemd systemd-cron sudo \
 # install ansible via pip
 && pip install $pip_packages \
 # clean up
 && apt autoremove -y \
 && apt clean \
 && rm -rf /var/lib/apt/lists/* \
           /var/tmp/* \
           /usr/share/doc \
           /usr/share/man \
 # remove python files
 && rm -rf /root/.cache/pip/ \
 && find / -name '*.pyc' -delete \
 && find / -name '*__pycache__*' -delete
