Cluster > Node > Pod > Container

There are two types of nodes:

• A Control-plane-node type, which makes up the Control Plane, acts as the “brains” of the cluster.
  
  

• A Worker-node type, which makes up the Data Plane, runs the actual container images (via pods).
  
  

Pod A thin wrapper around one or more containers

DaemonSet Implements a single instance of a pod on a worker node

Deployment Details how to roll out (or roll back) across versions of your application

ReplicaSet Ensures a defined number of pods are always running

Job Ensures a pod properly runs to completion

Service Maps a fixed IP address to a logical group of pods

Label Key/Value pairs used for association and filtering

Cluster > Node > Pod > Container

A container runs typically as a single Unix process
