Building and Using Micro Linux Distributions for Docker
summary
Survey of Docker-focused microdistros traces voodoo docker, docker toolbox, libmachine, Moby/Alpine, CoreOS, Project Atomic and Clear Linux, then drills into Rancher OS: Linux 4.9.15 bootstrap with BusyBox and a tiny Go init, ability to swap Docker engines (1.10–17.03), and two Docker layers: system-docker and user-docker. Services live as containers managed via cloud-config driven service repo (index.yaml); demo exposes an nginx service deployable on AWS/packet/digitalocean, and SELinux runs in permissive mode.
