Guide to the Kubernetes Load Balancer Service
A pod is Kubernetes’ smallest and simplest unit representing a single instance of a running process in a Kubernetes cluster. Pods contain one or more containers. They share the same network namespace to allow containers within the same pod to communicate with each other. However, a pod is updated and deleted based on the desired state defined by higher-level objects such as Deployments, StatefulSets, DaemonSets, and ReplicationControllers.
