pod/prometheus-k7-prom-prometheus-operato-prometheus-0 一直在创建状态

老师好, 请教下我使用的慕课仓库提供的文件, 执行 helm install 命令, pod/prometheus-k7-prom-prometheus-operato-prometheus-0 这个pod一直处于 ContainerCreating 状态, 请老师帮忙看下,谢谢

这个错误关注一下： Warning  FailedMount  6m57s (x40 over 72m)  kubelet, kaiqi-server-1094  MountVolume.SetUp failed for volume "secret-etcd-certs" : secret "etcd-certs" not found

手动查看一下是否存在这个secret，没有话得查查原因了，在values配置文件中有这么一段：

    ## Secrets is a list of Secrets in the same namespace as the Prometheus object, which shall be mounted into the Prometheus Pods.

    ## The Secrets are mounted into /etc/prometheus/secrets/. Secrets changes after initial creation of a Prometheus object are not

    ## reflected in the running Pods. To change the secrets mounted into the Prometheus Pods, the object must be deleted and recreated

    ## with the new list of secrets.

    ##

    secrets:

    - etcd-certs

    老师, 不好意思又来打扰了, 我检查了配置文件, 确实有
```
    ## Secrets is a list of Secrets in the same namespace as the Prometheus object, which shall be mounted into the Prometheus Pods.
    ## The Secrets are mounted into /etc/prometheus/secrets/. Secrets changes after initial creation of a Prometheus object are not
    ## reflected in the running Pods. To change the secrets mounted into the Prometheus Pods, the object must be deleted and recreated
    ## with the new list of secrets.
    ##
    secrets:

    - etcd-certs
```
这一段, 但是 kubectl get secret -n monitoring 没有发现 etcd-certs   , 请问这个 etcd-certs 是在执行 helm install 命令的时候自动创建的吗? 现在该怎么手动创建这个 etcd-certs 呢?
