I am trying to install docker cron package in running prometheus docker container. I downloaded cron package but somehow it is not allowing me do that. I downloaded cron package using wget command. Also it doesn't let me configure 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
Now when i try to create lib/dpkg folder in /var/ folder.
/prometheus # mkdir /var/lib/dpkg
mkdir: can't create directory '/var/lib/dpkg': No such file or directory
I don't understand what I am doing wrong. I don't see any disk space issue or inode issue.
/prometheus # df -kh

I don't have a /var/log/ folder either in my container where I check the logs.
and I am root as you can see below. It's busybox container since busybox is the base image used by prometheus.
/etc/prometheus # whoami
root
After running mkdir -p /var/lib/dpkg command I was able to get rid of previous error message just to land in new error.
/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
