This document introduces containers and Docker using Kubernetes. It discusses: - Linnovate, an Israeli open source solutions company that created MEAN.IO and supports Microsoft Azure, IDF, and GOV.IL. - The challenges of 100% uptime and fast response that containers address. - How containers are lightweight, open, and secure compared to VMs. - Kubernetes as an open source container cluster manager used by Google App Engine to run containers on private/public clouds and bare metal. - Moving applications to Docker by identifying separable parts, dockerizing each, testing, and running containers.

15. MOVING YOUR APPS TO DOCKERS
● Identify your app’s separable parts
● Dockerize each part
● Test and Run
● Visit https://registry.hub.docker.com to
discover the choice
● Try tools like Kitematic to try Docker locally
