Kubernetes Notes

Kubernetes is a distributed computing model used to create microservice based applications deployed onto a cluster.

Pods

The pod concept is the atom of kubernetes, the smallest unit that can be manipulated. A pod wraps one or more tightly coupled dockers images, but often only one.

A pod is a single unit of execution.

Deployment

A Deployment manages the life cycle of your pods. Pods are created and destroyed by Deployment object. When a pod dies, the Deployment is responsible for creating a new instance.

Service

A Service fronts a bunch of pods and provides a single point of contact for a series of ephemeral pods.
