Deploy sample application

# inject envoy proxy
kubectl label namespace bookinfo istio-injection=enabled

# apply bookinfo application
kubectl apply -f samples/bookinfo/platform/kube/bookinfo.yaml -n bookinfo

# veryfy deploy
➜ kubectl exec "$(kubectl get pod -l app=ratings -o jsonpath='{.items[0].metadata.name}')" -c ratings -- curl -sS productpage:9080/productpage | grep -o "<title>.*</title>"
<title>Simple Bookstore App</title>

• kubectl get pod -l app=ratings -o jsonpath='{.items[0].metadata.name}’
  • label이 app=ratings인 pod명 가져오기
• -c ratings
  • kubectl exec 명령어를 실행할때 pod내에 컨테이너가 여러개인 경우 -c option으로 특정 container명을 지정해야 한다.
