1.prometheus dingtalk 发送报警:

• promtheus 配置：

kind: ConfigMap
apiVersion: v1
metadata:
  name: alertmanager
  namespace: kube-system
data:
  config.yml: |-
    global:
      resolve_timeout: 5m
    route:
      receiver: webhook
      group_wait: 30s
      group_interval: 1m
      repeat_interval: 1m
      routes:
      - receiver: webhook
        group_wait: 10s
    receivers:
    - name: webhook
      webhook_configs:
      - url: 'http://10.255.72.206:80/' #这里地址是dingtalk的部署地址,后期可以通过k8s docker化成服务然后配置动态发现。
