OpenShift 4 之腳本化部署Istio的HelloWorld和BookInfo示例

本文采用全腳本實現《OpenShift 4 之通過命令創建Service Mesh環境》+《OpenShift 4 之運行Istio的BookInfo微服務應用》
運行環境：OpenShift 4.2.x

準備環境

yum install -y git jq
git clone https://github.com/liuxiaoyu-git/ocp4-servicemesh-bookinfo

安裝Service Mesh Operator

./ocp4-servicemesh-bookinfo/00-install-operator.sh

安裝Service Mesh Control Plane

./ocp4-servicemesh-bookinfo/01-deploy-control-plane.sh

查看Pod安裝進度，直到有12個Pod運行即可退出。

部署應用

HelloWorld

./ocp4-servicemesh-bookinfo/10-helloworld-deploy.sh

最後應該運行了這些Pod：

NAME                             READY   STATUS    RESTARTS   AGE
helloworld-v1-54fd8d846-txz2b    2/2     Running   0          6m54s
helloworld-v2-576ccf4654-6fcql   2/2     Running   0          6m54s
