Add batch version image

[TaoSunVoyage]

We need an image for batch execution:

• with out conda and jupyter stack
• pipx should install packages (including renku) in /share not in ~

A working example can be found below:

FROM renku/renkulab-py:3.8-0.7.7 as source

FROM python:3.8-slim

COPY --from=source /entrypoint.sh /entrypoint.sh

RUN apt-get update -y && \
    apt-get install -y curl && \
    curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | bash && \
    apt-get update -y && \
    apt-get install -y git git-lfs nodejs && \
    apt-get purge && \
    apt-get clean && \
    apt autoremove --yes && \
    rm -rf /var/lib/apt/lists/* 

COPY requirements.txt /tmp/
RUN pip install -r /tmp/requirements.txt && \
    pip install pipx 

# Override default location of pipx and app installation
ENV PIPX_BIN_DIR /share/bin
ENV PIPX_HOME /share/pipx
ENV PATH /share/bin:$PATH

RUN pipx install renku==0.15.1

ENTRYPOINT ["/entrypoint.sh"]
