CoreOS in Action

Summary

CoreOS in Action is a clear tutorial for deploying container-based systems on CoreOS Container Linux.

About the Technology

Traditional Linux server distributions include every component required for anything you might be hosting, most of which you don’t need if you’ve containerized your apps and services. CoreOS Container Linux is a bare-bones distro with only the essential bits needed to run containers like Docker. Container Linux is a fast, secure base layer for any container-centric distributed application, including microservices. And say goodbye to patch scheduling; when Container Linux needs an update, you just hot-swap the whole OS.
