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 ━━━━━━━━━━━━━━━━━━━━━━ 📦 Source Code https://github.com/dalita/devops-basi... 🎥 Playlist Kubernetes for Beginners ☕ Subscribe for more DevOps content ━━━━━━━━━━━━━━━━━━━━━━ Next Episode: Namespaces and ConfigMaps Learn how to organize applications inside a cluster, isolate environments, and manage configuration across development, testing, and production workloads.
