EP06 - Kubernetes Services & Networking

🚀 Kubernetes for Beginners Episode 6 Services and Networking

In this episode, we explore one of the most important concepts in Kubernetes: Services.
Pods are ephemeral. They can be recreated at any time, and when that happens, their IP addresses change. This raises an important question: how do applications communicate reliably inside a Kubernetes cluster?

We answer that question by exploring Kubernetes Services and the networking model that makes modern cloud-native applications possible.

Topics covered:

* Why Pod IP addresses are not reliable
* What a Kubernetes Service is
* Labels and Selectors
* Service Discovery and DNS
* ClusterIP
* NodePort
* LoadBalancer
* Service Endpoints
* Internal and External Communication

Hands-on demonstration:

* Creating a Deployment with multiple Nginx Pods
* Creating a Service using YAML
* Connecting Services to Pods through Labels and Selectors
* Inspecting Service Endpoints
* Deleting Pods and observing automatic recovery
* Understanding how Services maintain a stable endpoint while Pods change

Commands used:
kubectl apply -f nginx-deployment.yaml
kubectl apply -f nginx-service.yaml
kubectl get pods
kubectl get svc
kubectl get endpoints nginx-service
kubectl delete pod pod-name
kubectl delete deployment nginx
