构建这个Dockerfile：

FROM ubuntu:19.10

ENV DEBIAN_FRONTEND noninteractive

RUN apt-get update 
RUN apt-get install -y locales apt-utils
RUN sed -i -e 's/# en_US.UTF-8 UTF-8/en_US.UTF-8 UTF-8/' /etc/locale.gen && \
    dpkg-reconfigure locales && \
    update-locale LANG=en_US.UTF-8

ENV LANG en_US.UTF-8 

RUN apt-get install --no-install-recommends -y vim 

CMD /bin/bash

输出一些警告信息：

  1. 最好，我根本不希望安装手册页
  2. 我也不想要 de、fr、it、ja、pl、ru 语言的手册页（如果 1. 不可能，我只需要 en 手册页）

有没有办法阻止 apt 安装这些手册页，然后打印这些警告，因为它找不到它们的关联文件？

如果您只想节省磁盘空间和/或网络带宽，请尝试以下操作：

echo 'path-exclude /usr/share/doc/*' >/etc/dpkg/dpkg.cfg.d/docker-minimal && \ 
echo 'path-exclude /usr/share/man/*' >>/etc/dpkg/dpkg.cfg.d/docker-minimal && \
echo 'path-exclude /usr/share/groff/*' >>/etc/dpkg/dpkg.cfg.d/docker-minimal && \
echo 'path-exclude /usr/share/info/*' >>/etc/dpkg/dpkg.cfg.d/docker-minimal && \
echo 'path-exclude /usr/share/lintian/*' >>/etc/dpkg/dpkg.cfg.d/docker-minimal && \
echo 'path-exclude /usr/share/linda/*' >>/etc/dpkg/dpkg.cfg.d/docker-minimal && \
echo 'path-exclude /usr/share/locale/*' >>/etc/dpkg/dpkg.cfg.d/docker-minimal && \
echo 'path-include /usr/share/locale/en*' >>/etc/dpkg/dpkg.cfg.d/docker-minimal

只要您尝试安装一些 APT 软件包，就不会将手册页保存到磁盘。警告仍然存在，但手册页不存在。

这里的问题是某些包从 .deb 包的 postinst 部分调用 update-alternatives 二进制文件。请参阅https://manpages.debian.org/buster/dpkg/update-alternatives.1.en.html。不知道你是否也可以要求 DPKG 根本不执行 postinst 部分，但这听起来不太好！您还可以为 update-alternatives 编写一个小包装器以抑制警告，但这听起来很愚蠢。
