[Verse 1] In the cluster where containers breathe and dance Pods need pathways, not left to chance Each one gets an IP that's ephemeral But when pods crash, connections turn burial Services step in as the stable face Giving workloads a permanent place [Chorus] ClusterIP keeps it internal, NodePort opens the gate LoadBalancer routes the external, pod-to-pod can't wait Through the overlay network, packets find their way Services are the compass when pods drift away [Verse 2] ClusterIP is the default choice we make Internal traffic only, for the cluster's sake A virtual IP that never moves or dies While backend pods can multiply or resize DNS resolution makes the magic clean Service names resolve to IPs unseen [Chorus] ClusterIP keeps it internal, NodePort opens the gate LoadBalancer routes the external, pod-to-pod can't wait Through the overlay network, packets find their way Services are the compass when pods drift away [Verse 3] NodePort breaks the boundary wall apart Maps high ports where external clients start Thirty thousand range begins the ride Every node becomes a gateway wide But LoadBalancer brings the polish true Cloud providers hook the traffic through [Bridge] CNI plugins weave the network mesh Flannel, Calico make connections fresh Kube-proxy watches for the service change Updates iptables rules across the range East-west traffic flows from pod to pod While north-south needs a service nod [Chorus] ClusterIP keeps it internal, NodePort opens the gate LoadBalancer routes the external, pod-to-pod can't wait Through the overlay network, packets find their way Services are the compass when pods drift away [Outro] Endpoints track the healthy pod brigade Load balancing keeps the traffic splayed From service mesh to simple DNS Kubernetes networks handle the stress
