Prometheus是以operator方式部署 这里仅仅提供一个思路，万变不离其宗。 使用短信告警之前需要自己购买短信服务，然后定义好短信模板，一般都有现成的sdk，自己简单包装一下就可以使用了。

思路：通过自定义webhook的方式进行发送。
我简单写了一个webhook，项目地址：https://github.com/cool-ops/prometheus-alert-sms.git

部署

1、下载代码

  1. git clone https://github.com/cool-ops/prometheus-alert-sms.git

2、编译代码

  1. cd prometheus-alert-sms/
  2. sh build.sh

3、打包镜像

  1. docker build -t registry.cn-hangzhou.aliyuncs.com/rookieops/prometheus-alert-sms:v0.0.7 .

注：镜像地址更换成自己的仓库地址
4、推送镜像到镜像仓库

  1. docker push registry.cn-hangzhou.aliyuncs.com/rookieops/prometheus-alert-sms:v0.0.7

5、修改项目目录下的prometheus-alert-sms.yaml

  1. apiVersion: v1
  2. kind: ConfigMap
  3. metadata:
  4.   name: sms-conf
  5.   namespace: monitoring
  6. data:
  7.   sms.yaml: |
  8.     adapter:
  9.       adapter_name: "RongLianYun"
  10.     RongLianYun:
  11.       baseUrl : "https://app.cloopen.com:8883"
  12.       accountSid : "xxxxxx"
  13.       appToken   : "xxxxxx"
  14.       appId      : "xxxxx"
  15.       templateId : "xxx"
  16.       phones : ["11111111111","22222222222"]
  18.     AliYun:
  19.       aliRegion: "cn-hangzhou"
  20.       accessKeyId: "xxxx"
  21.       accessSecret: "xxxx"
  22.       phoneNumbers: "11111111111,22222222222"
  23.       signName: "xxxx"
  24.       templateCode: "xxxx"
  25. ---
  26. apiVersion: apps/v1
  27. kind: Deployment
  28. metadata:
  29.   name: prometheus-alert-sms
  30.   namespace: monitoring
  31. spec:
  32.   replicas: 1
  33.   selector:
  34.     matchLabels:
  35.       app: prometheus-alert-sms
  36.   template:
  37.     metadata:
  38.       labels:
  39.         app: prometheus-alert-sms
  40.     spec:
  41.       containers:
  42.         - name: prometheus-alert-sms
  43.           image: registry.cn-hangzhou.aliyuncs.com/rookieops/prometheus-alert-sms:v0.0.7
  44.           imagePullPolicy: IfNotPresent
  45.           livenessProbe:
  46.             failureThreshold: 3
  47.             httpGet:
  48.               path: /healthCheck
  49.               port: tcp-9000
  50.               scheme: HTTP
  51.             initialDelaySeconds: 30
  52.             periodSeconds: 10
  53.             successThreshold: 1
  54.             timeoutSeconds: 2
  55.             readinessProbe:
  56.               failureThreshold: 3
  57.               httpGet:
  58.                 path: /healthCheck
  59.                 port: tcp-9000
  60.                 scheme: HTTP
  61.               initialDelaySeconds: 30
  62.               periodSeconds: 10
  63.               successThreshold: 1
  64.               timeoutSeconds: 2
  65.           env:
  66.             - name: CONFIG_PATH
  67.               value: /app/conf/sms.yaml
  68.           ports:
  69.             - name: app-port
  70.               containerPort: 9000
  71.               protocol: TCP
  72.           resources:
  73.             limits:
  74.               cpu: 500m
  75.               memory: 1Gi
  76.             requests:
  77.               cpu: 500m
  78.               memory: 1Gi
  79.           volumeMounts:
  80.             - name: sms-conf
  81.               mountPath: /app/conf/sms.yaml
  82.               subPath: sms.yaml
  83.       volumes:
  84.         - name: sms-conf
  85.           configMap:
  86.             name: sms-conf
  87. ---
  88. apiVersion: v1
  89. kind: Service
  90. metadata:
  91.   name: prometheus-alter-sms
  92.   namespace: monitoring
  93. spec:
  94.   selector:
  95.     app: prometheus-alert-sms
  96.   ports:
  97.     - name: app-port
  98.       port: 9000
  99.       targetPort: 9000
  100.       protocol: TCP

到自己购买的短信服务获取对应的信息。
7、部署yaml文件

  1. kubectl apply -f prometheus-alert-sms.yaml

8、修改alertmanager的报警媒介

  1.  ......
  2.       - receiver: sms 
  3.         group_wait: 10s
  4.         match:
  5.           filesystem: node
  6.     receivers:
  7.     - name: 'sms'
  8.       webhook_configs:
  9.       - url: "http://prometheus-alter-sms.monitoring.svc:9000"
  10.         send_resolved: true
  11. ......

然后如果有报警就可以正常接受到报警了。
