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> -e ROBOT_SECRET=<钉钉机器人安全SECRET> -e LOG_LEVEL=debug -e PROME_URL=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
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> --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

kind: Service
metadata:

namespace: kube-ops
spec:

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
