This Alpine Linux base image uses a new “lean process manager” that simplifies management multi-process containers. It is just going into Beta.
This is a simplified image with a minimal install, and a quick placeholder application that runs upon startup.
If you want to see a typical use-case, see the “Try It” section on github, here: https://github.com/garywiz/chaperone-docker
