When you run the command kubectl get svc nginx-deployment -o yaml, Kubernetes will output the details of the Service named nginx-deployment in YAML format. This command is useful when you want to inspect the full configuration of a Service, including its metadata, selectors, ports, and other details.

Here’s an example of what the output might look like:

apiVersion: v1
kind: Service
metadata:
creationTimestamp: "2024-10-18T10:12:10Z"
name: nginx-deployment
namespace: default
resourceVersion: "456789"
uid: 12345abc-6789-defg-0123-hijklmnopqrst
spec:
clusterIP: 10.96.234.56
clusterIPs:
- 10.96.234.56
ipFamilies:
- IPv4
ipFamilyPolicy: SingleStack
ports:
- port: 80
protocol: TCP
targetPort: 80
selector:
app: nginx
sessionAffinity: None
type: ClusterIP
status:
loadBalancer: {}

Breakdown of the YAML Output:

  1. apiVersion: Specifies the API version for the resource (in this case, v1 for Services).
  2. kind: The resource type, which is Service here.
  3. metadata: Provides details about the Service such as its name, namespace, unique identifier (uid), and creation timestamp.
  • name: The name of the Service (nginx-deployment).
  • namespace: The namespace the Service belongs to…
