Pod Configuration

In order to be able to successfully configure a pod, we must first be able to read and understand a pod configuration file. Here is an example pod configuration file:

apiVersion: v1
kind: Pod
metadata:
  name: pod-name
spec:
  containers:
  - name: container1-name
    image: container1-image
  - name: container2-name
    image: container2-image

We can break down the configuration of a pod into four main components:

• apiVersion: Version of the Kubernetes API we are going to use.
• kind: The kind of Kubernetes object we are trying to create, which is a Pod in this case.
• metadata: Metadata or information that uniquely identifies the object we're creating.
• spec: Specification of our pod, such as container name, image name, volumes, and resource requests.

apiVersion, kind, and metadata apply to all types of Kubernetes objects and are required fields...
