发生了什么？ kubernetes 版本：1.12 promethus 操作员：release-0.1 我按照自述文件：
$ kubectl create -f manifests/
# It can take a few seconds for the above 'create manifests' command to fully create the following resources, so verify the resources are ready before proceeding.
$ until kubectl get customresourcedefinitions servicemonitors.monitoring.coreos.com ; do date; sleep 1; echo ""; done
$ until kubectl get servicemonitors --all-namespaces ; do date; sleep 1; echo ""; done
$ kubectl apply -f manifests/ # This command sometimes may need to be done twice (to workaround a race condition).
然后我使用命令然后显示如下：
[root@VM_8_3_centos /data/hansenwu/kube-prometheus/manifests]# kubectl get pod -n monitoring

我不知道为什么 pod altertmanager-main-0 挂起并显示然后重新启动。我看到了这个事件，它显示为：
72s Warning FailedCreate StatefulSet create Pod alertmanager-main-0 in StatefulSet alertmanager-main failed error: The POST operation against Pod could not be completed at this time, please try again.
