What is a Kubernetes Pod YAML file?

A Kubernetes Pod YAML file is a configuration file used to define a Pod in a Kubernetes cluster. It specifies the desired state, including the containers, their images, and other settings.

Can you show me an example of a simple Pod YAML?

Sure! Here's a basic example:

apiVersion: v1
kind: Pod
metadata:
  name: my-pod
spec:
  containers:
  - name: my-container
    image: nginx

This defines a Pod named 'my-pod' with a single container running the Nginx image.

What are the key fields in a Pod YAML?

The key fields include:

• apiVersion: Specifies the version of the Kubernetes API.
• kind: Defines the type of resource (e.g., Pod).
• metadata: Contains data that helps uniquely identify the object.
• spec: Describes the desired state of the Pod, including containers and their configurations.

How do I apply this YAML file to my cluster?

You can apply the YAML file using the command: kubectl apply -f your-pod-file.yaml. This will create the Pod in your Kubernetes cluster.
