Kubernetes introduces the concept of "pods", which are groupings of one or more containers and their shared storage, and any specific options on how these should be run together. Pods are used for tightly coupled applications that would typically run on the same logical host and which may require access to the same system resources. Typically, containers in a pod share the same network and memory space and can access shared volumes for storage. These shared resources allow the containers in a pod to communicate internally in a seamless way as if they were installed on a single logical host.
You can easily create or destroy pods as a set of containers. This makes it possible to do rolling updates to an application by controlling the scaling of the deployment. It also allows you to scale up or down easily by creating or removing replica pods. For more information on pods, see the upstream documentation at:
