istio-demo
This is a simple istio demo/example. This example is based on spring boot and create automatically a docker image. Change the docker image prefix in the pom.xml to be able to publish the image on your docker registry.
You will need for this demo:
- maven
- docker
- minikube
- kubectl
- istio
Example usage:
- build both services
mvn clean install - push to docker registry
docker push prefix/helloworld-service && docker push prefix/helloworld-service-caller - deploy service
kubectl apply -f kubernetes/helloworld-deployment-mpo.yaml - create service
kubectl apply -f kubernetes/helloworld-service-mpo.yaml - deploy service caller
kubectl apply -f kubernetes/helloworld-caller-deployment-mpo.yaml - create service caller
kubectl apply -f kubernetes/helloworld-caller-service-mpo.yaml - install istio :
kubectl apply -f $istio-path/install/kubernetes/helm/istio/templates/crds.yaml - sidecar injection:
kubectl label namespace default istio-injection=enabled --overwrite - restart services:
kubectl scale deployment helloworld-service --replicas=0 && kubectl scale deployment helloworld-service --replicas=2 - restart services caller:
kubectl scale deployment helloworld-service-caller --replicas=0 && kubectl scale deployment helloworld-service-caller --replicas=2 - create gateway:
kubectl apply -f istio-rules/helloworld-service-gateway.yml - test it
