13. Kubernetes Services: NodePort vs LoadBalancer 🚀

In this video, we dive into the differences between Kubernetes NodePort and LoadBalancer services, showing how they work and when to use them.

We'll start by setting up a NodePort service, which exposes your application on a static port (e.g., 30001) accessible on any node in your cluster:
yaml
Copy code
apiVersion: v1
kind: Service
metadata:
name: nginx-nodeport
spec:
type: NodePort
selector:
run: app-nginx
ports:
- nodePort: 30001
port: 80
targetPort: 80
Then, we'll explain the LoadBalancer service, which automatically provisions an external load balancer for distributing traffic across your application:
yaml
Copy code
apiVersion: v1
kind: Service
metadata:
name: nginx-load-balancer
spec:
type: LoadBalancer
selector:
run: app-nginx
ports:
- port: 80
targetPort: 80
You'll learn how these services fit into your Kubernetes architecture, with real-world examples to illustrate the key differences. Whether you're just starting or looking to refine your skills, this video covers everything you need to know about exposing Kubernetes applications externally!
