OpenShift 4 之脚本化部署Istio的HelloWorld和BookInfo示例

本文采用全脚本实现《OpenShift 4 之通过命令创建Service Mesh环境》+《OpenShift 4 之运行Istio的BookInfo微服务应用》
运行环境：OpenShift 4.2.x

准备环境

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

安装Service Mesh Operator

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

安装Service Mesh Control Plane

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

查看Pod安装进度，直到有12个Pod运行即可退出。

部署应用

HelloWorld

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

最后应该运行了这些Pod：

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

访问HelloWorld应用

source $HOME/.bashrc
curl -s http://${GATEWAY_URL}/hello

BookInfo

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

最后应该运行了这些Pod：

NAME                              READY   STATUS    RESTARTS   AGE

访问BookInfo应用

source $HOME/.bashrc
curl -s http://${GATEWAY_URL}/productpage | grep -o "<title>.*</title>"

更改规则策略

./ocp4-servicemesh-bookinfo/11-bookinfo-dr-all.sh
curl -s http://${GATEWAY_URL}/productpage | grep -o "<title>.*</title>"
