Nginx Service in Kubernetes

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…
