Assume there is no Kubernetes Cloud Provider Load Balancers available
- Have to use node port service to gain ingress traffic
- Have to manually configure an external load balancer for ingress traffic
Service Networking References:
- A Load Balancer front end port 80
- A wild card DNS record point to the load Balancer
./install-ingress-nginx.sh
curl -L https://git.io/getLatestIstio | sh -
kubectl apply -f install/kubernetes/istio.yaml
kubectl get services -n ingress-nginx
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
default-http-backend ClusterIP 10.100.200.140 <none> 80/TCP 3h
ingress-nginx NodePort 10.100.200.28 <none> 80:30314/TCP,443:32524/TCP 3h
kubectl get pods -n ingress-nginx

Point the Load Balancer to all the worker nodes IP:NodePort (30314 and 32524)
kubectl get service istio-ingress -n istio-system
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
istio-ingress LoadBalancer 10.100.200.56 <pending> 80:31385/TCP,443:30138/TCP 2m
Point the Load Balancer to all the worker nodes IP:NodePort (31385 and 30138)
kubectl create -f music1/namespace.yml
kubectl create -f music1/music.yml
kubectl get services -n music1
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
music-service ClusterIP 10.100.200.63 <none> 8080/TCP 2h
Provide the ingress rule based on the host header
kubectl create -f music1/ingress-nginx.yml
OR
kubectl create -f music1/ingress-istio.yml
Create another app
./install-music.sh music2 istio/nginx
