k8s系统，异常通知对接钉钉系统

1：首先在钉钉系统中自定义机器人记住webhoodk地址和自定义关键字，点击完成

2：创建test.ymal 文件，复制如下内容，修改webhook 地址，以及带上后面的参数
—sink=dingtalk:https:************&label=cluster1&level=Warning#钉钉对接的调用接口
label为对应的关键字，levle为对应的消息级别。如果需要监控具体的某个命名空间可以带上&namespaces=“要监控的资源空间”

3：登录k8s服务器后台，将文件传到服务器上，输入命令
kubectl apply -f test.yaml

4：当有节点异常时，会自动推送消息。通过查看大约30秒推送一次。
