Overview

Linux based, Docker-aimed supervisor with very low memory footprint and full control of targeted applications. nanoinit is a dependency-free, very lightweight supervisor application (daemon) especially crafted for using inside Docker containers. RAM size is as little as possible, dependent on the number of apps in the config file; usually does not exceed a few KB. The main reason behind this project is that we were usually using supervisord as the default supervisor for docker containers, but this came with a >100 MB Python and tons of packages, which made no sense when Python wasn't required for other purposes.
