A Kubernetes Pod is a group of one or more containers that are deployed together on the same host. Pods are the smallest deployable unit in Kubernetes and provide the basic building block for applications. All containers in a Pod share the same network namespace, allowing them to communicate with each other without being exposed to the outside world.
For example, if you wanted to run a web application in Kubernetes, you could create a Pod with a web server container and a database container. The web server container would be able to communicate with the database container without having to expose the database to the outside world.
