alertmanager-dingtalk-hook

AlertManager 钉钉报警简单服务示例

运行

使用Docker运行

$ docker run -p 5000:5000 --name -e ROBOT_TOKEN=<钉钉机器人TOKEN> dingtalk-hook -d yangpeng2468/alertmanager-dingtalk-hook:v1 

在Kubernetes集群中运行

第一步建议将钉钉机器人TOKEN创建成Secret资源对象：

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

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

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: dingtalk-hook
  namespace: kube-ops
spec:
  template:
    metadata:
      labels:
        app: dingtalk-hook
    spec:
      containers:
      - name: dingtalk-hook
        image: yangpeng2468/alertmanager-dingtalk-hook:v1
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 5000
          name: http
        env:
        - name: ROBOT_TOKEN
          valueFrom:
            secretKeyRef:
              name: dingtalk-secret
              key: token
        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.extensions "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
