Is Kubernetes same as Docker?

Kubernetes supports numerous container runtimes including Docker, containerd, CRI-O, and any implementation of the Kubernetes CRI (Container Runtime Interface).
Is a Kubernetes node a host?
A Kubernetes cluster consists of a set of worker machines, called nodes, that run containerized applications. Every cluster has at least one worker node. The worker node(s) host the Pods that are the components of the application workload.
Are Kubernetes pods Docker containers?
Pods are the smallest, most basic deployable objects in Kubernetes. A Pod represents a single instance of a running process in your cluster. Pods contain one or more containers, such as Docker containers. When a Pod runs multiple containers, the containers are managed as a single entity and share the Pod’s resources.
Why does Kubernetes use Docker?
For development, this provides an essential advantage: Kubernetes can create containers from images stored in the Docker Engine image cache. We can build images locally and test them right away without having to push them to a registry first.
