What is the purpose of the Pod object in Kubernetes?

In Kubernetes, a Pod object is the smallest and most basic deployable unit. A Pod consists of one or more containers that run on a single node and share an IP address as well as common resources such as storage volumes. The main purpose of a Pod is to ensure the co-location and co-execution of containers that are closely related and need to work together, for example, an application container and a logging container. A Pod manages the lifecycle of these containers as a single entity.
