Minikube
Start / Stop:
minikube start
minikube stop
Create tunnel and access loadbancer, in a new terminal session. When requested, authenticate. Keep this session open and active!
minikube tunnel
Bookinfo App
Access the Bookinfo application:
export INGRESS_HOST=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
export INGRESS_PORT=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(@.name=="http2")].port}')
echo http://$INGRESS_HOST:$INGRESS_PORT/productpage
Generate some load on Bookinfo instance. In a new session enter the following commands:
export INGRESS_HOST=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
export INGRESS_PORT=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(@.name=="http2")].port}')
watch curl http://$INGRESS_HOST:$INGRESS_PORT/productpage
This will access Bookinfo every 2 seconds until terminated. Keep this running during this exercise.
Kiali
kubectl port-forward service/kiali 20001:20001 -n istio-system
