What is this?
Services give stable virtual IPs/DNS to a set of Pods selected by labels.
Why should you care?
CloudVerse apps call `http://orders` — not Pod IPs that change.
See it live — copy this example
Use AWS/Azure/GCP free tier or local Docker/Kind. Sketches and YAML are meant to be typed and adapted.
apiVersion: v1
kind: Service
metadata: { name: orders }
spec:
selector: { app: orders }
ports: [{ port: 80, targetPort: 8080 }]
type: ClusterIPWhat happened?
- ClusterIP internal; LoadBalancer/NodePort for external patterns.
- Keep selectors aligned with Pod labels.
Practice next
- Create Service + Deployment labels.
- curl from another Pod.
- Watch Endpoints.
- Try headless service.
- Add externalName for hybrid.
Remember
Stable DNS/IP. Label selectors. ClusterIP default.
CloudVerse orders Service
Other pods call orders:80.
Outcome: Stable discovery inside cluster.
