Luet is a multi-platform Package Manager based off from containers - it uses Docker (and other tech) to sandbox your builds and generate packages from them. It has no dependencies and it is well suitable for "from scratch" environments. It can also version entire rootfs to enable delivery of OTA-alike updates.

Luet offers a simple [specfile format](https://luet-lab.github.io/docs/docs/concepts/specfile/) in YA<ML notation to define both packages and rootfs. As it is based on containers, it can be used to build seed stages for Linux From Scratch installations and it can build and track updates.

It is written entirely in Golang and where used as package manager, it can run in from scratch environment, with zero dependencies.

## In a glance

- Luet can reuse Gentoo's portage tree hierarchy, and it is heavily inspired from it.
- It builds, installs, uninstalls and perform upgrades on machines
- Installer doesn't depend on anything ( 0 dep installer !)
- Support for packages as "layers"
- It uses SAT solving techniques to solve the deptree ( Inspired by [OPIUM](https://ranjitjhala.github.io/static/opium.pdf) )

## Install

To install luet, you can grab a release on the [Release page](https://github.com/mudler/luet/releases) or compile it in your machine (requires Golang installed):

    $ git clone https://github.com/mudler/luet.git
    $ cd luet
    $ make build

## Status

Luet is not feature-complete yet, it can build, install/uninstall/upgrade packages - but it doesn't support yet all the features you would normally expect from a Package Manager nowadays.

## Documentation

[Docs](https://https://luet-lab.github.io/docs) are available, or
run `luet --help`,  any subcommand is documented as well: `luet build --help`.
