Open. Shift runs on your choice of infrastructure RHEL 7. 1 또는 RHEL Atomic Host 7. 1. 6

Nodes are instances of RHEL where apps will run 최초 설치 후 모습

Pods run one or more docker containers as a unit 스케일링되는 가장 작은 단위: POD

Pod placement is determined based on defined policy Region 및 Zone 지정 가능 스케쥴러에 의해 선택

Services allow related pods to connect to each other

Management/Replication controller manages the pod lifecycle

What if a pod goes down?

Open. Shift automatically recovers and deploys a new Pod

Pods can attach to shared storage for stateful services

Routing layer routes external app requests to pods

Developers access Open. Shift via Web, CLI or IDE
