In Kubernetes, a pod is the basic unit of deployment. It is the smallest deployable unit in the Kubernetes object model.

A pod consists of one or more containers, such as Docker containers, and is used to host the containers that make up an application. The containers in a pod share the same network namespace and can communicate with each other using localhost. Pods are also co-located and co-scheduled, which means that they are scheduled to run on the same node and they share the same resources (e.g. CPU, memory).

Pods are intended to be ephemeral, meaning that they are expected to be terminated and replaced over time. This allows for easy scaling and rolling updates of applications.

Pods are created and managed by the Kubernetes control plane, which is responsible for ensuring that the desired number of replicas of a pod are running at any given time.
