What is minikube?
Ans:- Minikube is a tool that quickly sets up a local Kubernetes cluster on macOS, Linux, and Windows. It can deploy as a VM, a container, or on bare metal.
Minikube is a pared-down version of Kubernetes that gives you all the benefits of Kubernetes with a lot less effort.
This makes it an interesting option for users who are new to containers, and also for projects in the world of edge computing and the Internet of Things.

What are pods?
-Pods are the smallest deployable units of computing that you can create and manage in Kubernetes.
-A Pod (as in a pod of whales or pea pod) is a group of one or more containers, with shared storage and network resources, and a specification for how to run the containers.
-A Pod's contents are always co-located and co-scheduled, and run in a shared context.
-A Pod models an application-specific "logical host": it contains one or more application containers that are relatively tightly coupled.
