At the same time, node components try to achieve the state specified in the resources. If a Kubernetes resource is assigned to a node, the node components focus on attaching the required volumes and network interfaces to keep the application up and running.

Let's assume you will deploy the backend of the InstantPizza reservation system on Kubernetes. The backend consists of a database and a web server for handling REST operations. You will need to define a couple of resources in Kubernetes:
