Kubernetes Services with YAML |
Learn to write and test Kubernetes Services with YAML |
- We are going to look in to below two services in detail with a frotnend and backend example
- LoadBalancer Service
- ClusterIP Service
- Write the Deployment template for backend REST application.
- Write the Cluster IP service template for backend REST application.
- Important Notes:
- Name of Cluster IP service should be
name: my-backend-servicebecause same is configured in frontend nginx reverse proxydefault.conf. - Test with different name and understand the issue we face
- We have also discussed about in our Section-12
- Name of Cluster IP service should be
# Change Directory
cd kube-manifests
# Deploy Backend Kubernetes Deployment and ClusterIP Service
kubectl get all
kubectl apply -f 01-backend-deployment.yml -f 02-backend-clusterip-service.yml
kubectl get all- Write the Deployment template for frontend Nginx Application
- Write the LoadBalancer service template for frontend Nginx Application
# Change Directory
cd kube-manifests
# Deploy Frontend Kubernetes Deployment and LoadBalancer Service
kubectl get all
kubectl apply -f 03-frontend-deployment.yml -f 04-frontend-LoadBalancer-service.yml
kubectl get all- Access REST Application
# Get Service IP
kubectl get svc
# Access REST Application
http://<Load-Balancer-Service-IP>/hello
curl http://<Load-Balancer-Service-IP>/hello# Change Directory
cd kube-manifests/
# Delete Objects File by file
kubectl delete -f 01-backend-deployment.yml -f 02-backend-clusterip-service.yml -f 03-frontend-deployment.yml -f 04-frontend-LoadBalancer-service.yml
kubectl get all# Change Directory
cd 17-yaml-declarative-k8s-services/
# Recreate Objects by referencing a folder
kubectl apply -f kube-manifests/
kubectl get all# Change Directory
cd 17-yaml-declarative-k8s-services/
# Delete Objects by just referencing a folder
kubectl delete -f kube-manifests/
kubectl get all
