我正在尝试在运行的 prometheus docker 容器中安装 docker cron 包。我下载了 cron 包，但不知何故它不允许我这样做。我使用 wget 命令下载了 cron 包。此外，它不允许我配置 dpkg。
/prometheus # dpkg --configure
dpkg: can't open '/var/lib/dpkg/status': No such file or directory
/prometheus # dpkg -i cron_3.0pl1-127+deb8u1_amd64.deb
dpkg: can't open '/var/lib/dpkg/status': No such file or directory
现在，当我尝试lib/dpkg在文件夹中创建文件夹时/var/。
/prometheus # mkdir /var/lib/dpkg
mkdir: can't create directory '/var/lib/dpkg': No such file or directory
我不明白我做错了什么。我没有看到任何磁盘空间问题或 inode 问题。
/prometheus # df -kh

我的容器中也没有用于/var/log/检查日志的文件夹。我是 root 用户，如下所示。它是 busybox 容器，因为 busybox 是 prometheus 使用的基础映像。
/etc/prometheus # whoami
root
运行mkdir -p /var/lib/dpkg命令后，我能够摆脱之前的错误消息，但却遇到新的错误。
/prometheus # dpkg -i cron_3.0pl1-127+deb8u1_amd64.deb
dpkg: package cron pre-depends on dpkg, which is not installed or flagged to be installed
