IP sale of configuration management tools written in Elixir for managing Debian-based Linux machines

I am selling all of the intellectual property that I have developed for managing Linux machines, listed in the inventory below. This IP may be particularly valuable to companies that fit one of these categories:

All rights to the property will be transferred to the buyer. Please send inquiries to Ivan Kozik at ivan@ludios.org.

This software has been used in production for over a year. It is easy to extend and debug. The choice of using Elixir has worked out well and has made the codebase very readable.

Why?

I was developing a product that required me to manage a lot of Linux machines. Writing this management software took longer than expected and, to the right company, will be worth more than what I was originally doing.

converge

converge is the library that implements the units used to configure machines.

base_system

base_system is our opinionated base setup for Linux machines. It runs its own units along with units from every role that is tagged for the machine (see the machine_manager section). base_system does:

machine_manager

machine_manager puts everything together: it is the end-user tool for managing many machines in parallel. machine_manager:
