+  Defines how each object, like Pods or Services, should be configured and its desired state.
+
+<!--more-->
+Almost every Kubernetes object includes two nested object fields that govern the object's configuration: the object spec and the object status. For objects that have a spec, you have to set this when you create the object, providing a description of the characteristics you want the resource to have: its desired state.
+
+It varies for different objects like Pods, StatefulSets, and Services, detailing settings such as containers, volumes, replicas, ports,   
+and other specifications unique to each object type. This field encapsulates what state Kubernetes should maintain for the defined   
+object.
