Pod : just a containerized application

When we create a Deployment on Kubernetes, that Deployment creates Pods with containers inside them

A Pod is a Kubernetes abstraction that represents a group of one or more application containers

Node: worker machine on which the pod runs.

A Pod always runs on a Node.

Node can have multiple pods

A Kubernetes cluster is a set of nodes that run containerized applications They are more lightweight and flexible than virtual machines.

• kubectl get - list resources
• kubectl describe - show detailed information about a resource
• kubectl logs - print the logs from a container in a pod
