helm install ./prometheus-operator/ 的问题

Question

老师，我使用helm2.13.1 执行helm install ./prometheus-operator/ --name imooc-prom --namespace monitoring 报错，通过学员说换成2.14.X就可以执行了。
我用的是2.14.3执行成功的。
然后就这两个起不来：

[root@master01 ~]# kubectl get all -n monitoring
NAME READY STATUS RESTARTS AGE
pod/alertmanager-imooc-prom-prometheus-oper-alertmanager-0 1/2 CrashLoopBackOff 8 21m

查看了日志：

在安装helm的时候使用：【请问/etc/kubernetes/ssl/tiller001.pem 这些怎么生成的？课程没有说明】
也不清楚是不是这个原因？？？
helm init --service-account tiller --upgrade -i registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.13.1 --tiller-tls-cert /etc/kubernetes/ssl/tiller001.pem --tiller-tls-key /etc/kubernetes/ssl/tiller001-key.pem --tls-ca-cert /etc/kubernetes/ssl/ca.pem --tiller-namespace kube-system --stable-repo-url https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts

你好，先确认下，用的是否是慕课网git仓库中的这个文件夹（deep-in-kubernetes/12-monitoring/prometheus-operator)，如果不是的话就先清理一下环境，然后用这里的文件尝试一下。

另外tiller001这些文件是指定一个位置而已，不需要文件存在。
