Introduction to Pods

What is a Pod?

A pod is the smallest object that can be created in Kubernetes. It consists of one or more containers that are tightly coupled and is the central object type on top of which others build their functionalities. Containers in a pod are created, managed, and destroyed together. Containers in the same pod share the same resources such as storage, network, namespace, among others and can easily communicate with one another on localhost. A container in one pod can communicate with a container in another pod using the pod IP address.
