[运维]4.bookinfo无法部署的问题
为了拉取镜像，搭建了阿里云镜像仓库，教程见：K8S中基于NFS-Subdir-External-Provisioner存储组件实现的StorageClass-CSDN博客
但是bookinfo的ratings和productpage无法运行，部署后显示crashLoopBackOff
[root@master ~]# kubectl get pods -owide

由于所有的镜像（review三个、details、ratings、productpage）都是1.19.1，后尝试重新下载镜像也不行。错误日志如下：

最后尝试使用了不匹配的ratings和productPage镜像版本，反而可以正常运行：
docker.io/istio/examples-bookinfo-productpage-v1:1.16.2
docker.io/istio/examples-bookinfo-ratings-v1:1.15.0修改istio/samples/bookinfo/plateform/kube路径下的bookinfo.yaml文件，将里面的deployment的版本改为对应的镜像版本，从而成功部署。
