参考配置

http://xxxxxxxxx/plugins/grafana-kubernetes-app/page/cluster-config ,改成你的grafana地址

prometheus1

# 刷新Prometheus配置

curl -X POST http://prometheus.yfklife.cn/-/reload

# 配置grafana数据源（prometheus）

启用【kubernetes】插件，点击左边【k8s图标】，点击【New Clusters】

复制证书 client证书为/root/.kube/config,需要对其进行解码，我这里是二进制安装的，目录文件有点不一样

ca.pem ，client.pem ，client-key.pem

cat /opt/kubernetes/server/bin/conf/kubelet.kubeconfig | grep certificate-authority-data | cut -d ' ' -f 6 | base64 -d
cat /opt/kubernetes/server/bin/conf/kubelet.kubeconfig | grep client-certificate-data | cut -d ' ' -f 6 | base64 -d
cat /opt/kubernetes/server/bin/conf/kubelet.kubeconfig | grep client-key-data | cut -d ' ' -f 6 | base64 -d
