title: Install a package manager inside docker container for images like 'prom/busybox'
body: <p>I'm trying to troubleshoot one of my running containers, which is based on image '<a href="https://hub.docker.com/r/prom/busybox/" rel="nofollow noreferrer">prom/busybox</a>'</p>
  
  <p>I wanted to install some packages like curl, etc. This image has no default package managers like apk or apt installed. I tried looking for some way to do that, but was not successful. Any hints to do this are most welcome.</p>
