Alertmanager配置短信告警

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

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


2、编译代码

cd prometheus-alert-sms/
sh build.sh


3、打包镜像

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

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

apiVersion: v1
kind: ConfigMap
metadata:
name: sms-conf
namespace: monitoring
data:
sms.yaml: |
adapter:
adapter_name: "RongLianYun"
RongLianYun:
baseUrl : "https://app.cloopen.com:8883"
accountSid : "xxxxxx"
appToken : "xxxxxx"
appId : "xxxxx"
templateId : "xxx"
phones : ["11111111111","22222222222"]
AliYun:
aliRegion: "cn-hangzhou"
accessKeyId: "xxxx"
accessSecret: "xxxx"
phoneNumbers: "11111111111,22222222222"
signName: "xxxx"
templateCode: "xxxx"
---
apiVersion: apps/v1
kind: Deployment
metadata:
name: prometheus-alert-sms
namespace: monitoring
spec:
replicas: 1
selector:
matchLabels:
app: prometheus-alert-sms
template:
metadata:
labels:
app: prometheus-alert-sms
spec:
containers:
- name: prometheus-alert-sms
image: registry.cn-hangzhou.aliyuncs.com/rookieops/prometheus-alert-sms:v0.0.7
imagePullPolicy: IfNotPresent
livenessProbe:
failureThreshold: 3
httpGet:
path: /healthCheck
port: tcp-9000
scheme: HTTP
initialDelaySeconds: 30
periodSeconds: 10
successThreshold: 1
timeoutSeconds: 2
readinessProbe:
failureThreshold: 3
httpGet:
path: /healthCheck
port: tcp-9000
scheme: HTTP
initialDelaySeconds: 30
periodSeconds: 10
successThreshold: 1
timeoutSeconds: 2
env:
- name: CONFIG_PATH
value: /app/conf/sms.yaml
ports:
- name: app-port
containerPort: 9000
protocol: TCP
resources:
limits:
cpu: 500m
memory: 1Gi
requests:
cpu: 500m
memory: 1Gi
volumeMounts:
- name: sms-conf
mountPath: /app/conf/sms.yaml
subPath: sms.yaml
volumes:
- name: sms-conf
configMap:
name: sms-conf
---
apiVersion: v1
kind: Service
metadata:
name: prometheus-alter-sms
namespace: monitoring
spec:
selector:
app: prometheus-alert-sms
ports:
- name: app-port
port: 9000
targetPort: 9000
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

kubectl apply -f prometheus-alert-sms.yaml


8、修改alertmanager的报警媒介

......
- receiver: sms
group_wait: 10s
match:
filesystem: node
receivers:
- name: ‘sms‘
webhook_configs:
- url: "http://prometheus-alter-sms.monitoring.svc:9000"
send_resolved: true
......


然后如果有报警就可以正常接受到报警了。

PS：因为这个是按照我自己的短信模板进行开发的，可能并不适合你，你可以做相应的修改。
