Overview
Pod
A pod is a group of one or more containers Kubernetes deploys and manages a compute unit, and the specification for how to run the containers. Kubernetes will not manage compute entities with smaller granularity, such as containers or processes.
The containers of a pod are atomically deployed and managed as a group. A useful mental model to use when thinking of a pod is that of a logical host, where all its containers share a context.
