Kubernetes Service Example Programs

Here’s a complete YAML file that contains three Deployments and their corresponding Services:

1. ClusterIP (default) for scmgalaxy/nginx-devopsschoolv1
2. NodePort for scmgalaxy/nginx-devopsschoolv2
3. LoadBalancer for rajeshmode/honda-gallery

Each container runs on port 80.
