How To Install microdnf on CentOS 8
Introduction
In this tutorial we learn how to install microdnf on CentOS 8.
What is microdnf
Micro DNF is a very minimal C implementation of DNF’s install, upgrade, remove, repolist, and clean commands, designed to be used for doing simple packaging actions in containers when you don’t need full-blown DNF and you want the tiniest useful containers possible. That is, you don’t want any interpreter stack and you want the most minimal environment possible so you can build up to exactly what you need. This is not a substitute for DNF for real systems, and many of DNF’s capabilities are intentionally not implemented in Micro DNF.
