What is considered the basic computing unit in Kubernetes?

The basic computational unit in Kubernetes is the Pod.

A Pod is the smallest and simplest unit in the Kubernetes object model that you can create or deploy. A Pod can contain one or more containers, which are usually tightly coupled and share resources such as network and storage.

Example: If you have an application consisting of multiple containers that need to work together (for example, a web server and a logging helper container), you group them into a single Pod.

apiVersion: v1
kind: Pod
metadata:
  name: example-pod
spec:
  containers:
  - name: app-container
    image: nginx
  - name: sidecar-container
    image: busybox
    command: ['sh', '-c', 'echo Hello Kubernetes']
