运行

使用Docker运行

$ docker run -p 5000:5000 --name -e ROBOTTOKEN=<钉钉机器人TOKEN> -e ROBOTSECRET=<钉钉机器人安全SECRET> -e LOGLEVEL=debug -e PROMEURL=prometheus.local dingtalk-hook -d cnych/alertmanager-dingtalk-hook:v0.3.5

环境变量配置：

• ROBOT_TOKEN：钉钉机器人 TOKEN
• PROME_URL：手动指定跳转后的 Promethues 地址，默认会是 Pod 的地址
• LOG_LEVEL：日志级别，设置成 debug 可以看到 AlertManager WebHook 发送的数据，方便调试使用，不需调试可以不设置该环境变量
• ROBOT_SECRET：为钉钉机器人的安全设置密钥，机器人安全设置页面，加签一栏下面显示的 SEC 开头的字符串

在Kubernetes集群中运行

$ kubectl create secret generic dingtalk-secret --from-literal=token=<钉钉群聊的机器人TOKEN> --from-literal=secret=<钉钉群聊机器人的SECRET> -n kube-ops
secret "dingtalk-secret" created

然后定义Deployment和Service资源对象：(dingtalk-hook.yaml)

apiVersion: apps/v1 kind: Deployment metadata:   name: dingtalk-hook   namespace: kube-ops spec:   selector:     matchLabels:       app: dingtalk-hook   template:     metadata:       labels:         app: dingtalk-hook     spec:       containers:       - name: dingtalk-hook         image: cnych/alertmanager-dingtalk-hook:v0.3.6         imagePullPolicy: IfNotPresent         ports:         - containerPort: 5000           name: http         env:         - name: PROME_URL           value: prometheus.local         - name: LOG_LEVEL           value: debug         - name: ROBOT_TOKEN           valueFrom:             secretKeyRef:               name: dingtalk-secret               key: token         - name: ROBOT_SECRET           valueFrom:             secretKeyRef:               name: dingtalk-secret               key: secret         resources:           requests:             cpu: 50m             memory: 100Mi           limits:             cpu: 50m             memory: 100Mi


apiVersion: v1
kind: Service
metadata:
  name: dingtalk-hook
  namespace: kube-ops
spec:
  selector:
    app: dingtalk-hook
  ports:
  - name: hook
    port: 5000
    targetPort: http

直接创建上面的资源对象即可：

$ kubectl create -f dingtalk-hook.yaml deployment.apps "dingtalk-hook" created service "dingtalk-hook" created $ kubectl get pods -n kube-ops NAME                            READY     STATUS      RESTARTS   AGE dingtalk-hook-c4fcd8cd6-6r2b6   1/1       Running     0          45m ......

最后在AlertManager中 webhook 地址直接通过 DNS 形式访问即可：

receivers: 
name: 'webhook'
 
  webhook_configs:   - url: 'http://dingtalk-hook.kube-ops.svc.cluster.local:5000'     send_resolved: true
