我正在Docker 映像(基于 Debian Bullseye)fcgiwrap
上安装该软件包,但某些文件似乎丢失了。nginx
这可能是显而易见的事情,但我找不到解释,这是我尝试过的一切:
1. 使用包构建 Docker 镜像
FROM nginx:latest
RUN apt-get update \
&& apt-get -q install -y \
fcgiwrap \
&& rm -rf /var/lib/apt/lists/*
运行后(即docker run -it my-image /bin/bash
),如果我列出,/usr/share/doc/fcgiwrap
我只能看到一个copyright
文件和空examples
文件夹。
2.运行基础镜像并直接安装
docker run -it nginx /bin/bash
然后apt install fcgiwrap
,文件仍然丢失。
3. 运行基础镜像并安装dpkg
docker run -it nginx /bin/bash
然后:
apt-get install -d fcgiwrap
cd /var/cache/apt/archives
,显示:
fcgiwrap_1.1.0-12_amd64.deb libfcgi0ldbl_2.4.2-2_amd64.deb partial
libfcgi-bin_2.4.2-2_amd64.deb lock spawn-fcgi_1.6.4-2_amd64.deb
dpkg --contents fcgiwrap_1.1.0-12_amd64.deb

知道这里发生了什么吗?
答案1
我想我问得太早了,看起来有些 Docker 镜像默认禁用安装文档,使用类似于以下的规则:https://askubuntu.com/a/541061,在文件中/etc/dpkg/dpkg.cfg.d/docker
。
