!!! Overview
[{$pagename}] is an [Abstraction] that represents a group of one or more application containers (such as [Docker] or rkt), and some shared [resources] for those [containers]. 


A Pod models an application-specific "logical host" and can contain different application containers which are relatively tightly coupled. For example, a Pod might include both the [container] with your [Node.js] app as well as a different [container] that feeds the [data] to be published by the [Node.js] web server. The containers in a Pod share an [IP Address] and port space, are always co-located and co-scheduled, and run in a shared [context] on the same Node.

[{$pagename}]s are the [atomic] unit on the [Kubernetes] platform. When we create a [Deployment] on [Kubernetes], that Deployment creates [{$pagename}]s with [containers] inside them (as opposed to creating [containers] directly). Each [{$pagename}] is tied to the [Kubernetes] [Node] where it is scheduled, and remains there until termination (according to restart policy) or deletion. In case of a Node failure, identical Pods are scheduled on other available Nodes in the cluster.

[Containers] should only be scheduled together in a single [Kubernetes Pod] if they are tightly coupled and need to share [resources] such as [disk].
