nFPM

nFPM is a simple, 0-dependencies, deb, rpm and apk packager.

Why

While fpm is great, for me, it is a bummer that it depends on ruby, tar and other software.

I wanted something that could be used as a binary and/or as a library and that was really simple.

So I created nFPM: a simpler, 0-dependency, as-little-assumptions-as-possible alternative to fpm.

Usage

Special thanks 🙏

Thanks to the fpm authors for fpm, which inspires nfpm a lot.
