I have written a minimal package manager using Go, which currently only has the install functionality, and plan to continuously add features like remove and query in the future.

motivation

in container environments, using RPM package managers results in too many dependencies, and the installation size is at least 100+ MB, which significantly affects our usage. In the context of container image building, a package manager is indispensable. Trimming down the existing dnf (C) functionality is very complex. Therefore, I ultimately chose to write a simple package manager using Go.

Like Redhat:

name	size	Desc
ubi9-minimal	98.7MB	microdnf package manager
ubi9	230M	dnf package manager

But godnf just 4.5M. We just add /etc/os-release, repo file, static busybox, then it already meets many scenarios.

name	size	Desc
godnf	6.8M	godnf packager manager

usage:
