我尝试在我的 3 节点 kubernetes 安装上安装 Prometheus 运算符。
# kubectl cluster-info
Client Version: version.Info{Major:"1", Minor:"7", GitVersion:"v1.7.3+coreos.0", GitCommit:"42de91f04e456f7625941a6c4aaedaa69708be1b", GitTreeState:"clean", BuildDate:"2017-08-07T19:44:31Z", GoVersion:"go1.8.3", Compiler:"gc", Platform:"linux/amd64"}

# kubectl get nodes
NAME STATUS AGE VERSION
master-k8s Ready 64d v1.7.3+coreos.0
worker1-k8s Ready 64d v1.7.3+coreos.0
worker2-k8s Ready 64d v1.7.3+coreos.0
What i did is
# git clone https://github.com/coreos/prometheus-operator
# cd cd prometheus-operator/
changed default namespace to monitoring at bundle.yaml
# kubectl apply -f bundle.yaml -n monitoring
然后我做了
# cd contrib/kube-prometheus
# hack/cluster-monitoring/deploy
当我查看 Grafana 界面时，我没有看到数据源，所以我应用了 yaml 文件。
# kubectl apply -f manifests/grafana/ -n monitoring
# kubectl get all -n monitoring

这次可以看到 prometheus 数据源，但没有可用的仪表板。
似乎缺少了什么。任何想法？
