yum的Docker多阶段构建

Question

我正在尝试从centos构建多阶段docker镜像

FROM centos as python-base

RUN yum install -y wget \
tar \
make \
gcc \
gcc-c++ \
zlib \
zlib-devel \
libffi-devel \
openssl-devel \
&& yum clean all

WORKDIR /usr/src/

RUN wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz

RUN tar xzf Python-3.7.0.tgz

WORKDIR /usr/src/Python-3.7.0

RUN ./configure --enable-optimizations

RUN make altinstall

RUN python3.7 -V

#=====================================================================================

FROM centos:cs as python37

COPY --from=python-base /usr/local/lib/python3.7 /usr/local/lib/python3.7
COPY --from=python-base /usr/local/bin/pip3.7 /usr/local/bin/pip3.7
COPY --from=python-base /usr/local/bin/python3.7 /usr/local/bin/python3.7

RUN ln -s /usr/local/bin/pip3.7 /usr/local/bin/pip
RUN ln -s /usr/local/bin/python3.7 /usr/local/bin/python

如上所示，我已经从python-base阶段构建了python37。在这里，我已将所需的工件从python-base复制到python37阶段。

FROM centos as httpd-base

RUN yum -y groupinstall "Development tools"\
httpd-2.4.6-88.el7.centos.x86_64 \
&& yum clean all

所以我的问题是，从httpd-base阶段复制什么构件才能构建具有httpd的映像，而不是仅在安装过程中需要的所有开发工具。

在这方面的任何最佳做法也值得赞赏。 提前致谢。
