Kubernetes Structure

Note
Here’s explanation of Kubernetes structure that I understand.
So, it could be wrong.
I just record for memory.

Cluster

A computing set they have a same purpose.
In Kubernetes, there are Master and Node.

Master

A controller for managing the Cluster.

Node

This is a physical machine that is for deploying containers.

POD

The POD is a deployment unit in Kubernetes.
A POD has multiple containers.
The Kubernetes is managing this unit.
In a Node can have multiple POD.

Reason why Kubernetes manage by unit POD
In a POD is sharing IP and Port.
In a POD can share disk volumes.

Container

This is a technology for virtualization based on linux.
