Pods are designed to run multiple cooperative processes that should act as a cohesive unit. Those processes are wrapped in containers. All the containers that form a Pod are running on the same machine. A Pod cannot be split across multiple nodes.
All the processes (containers) inside a Pod share the same set of resources, and they can communicate with each other through localhost. One of those shared resources is storage. A volume defined in a Pod can be accessed by all the containers thus allowing them all to share the same data. We'll explore storage in more depth later on. For now, let's take a look at the pod/go-demo-2.yml specification:
cat pod/go-demo-2.yml
The output is as follows:
apiVersion: ...
