安装流程

提示

在安装之前请确保您已经存在Kubernetes集群；

安装步骤如下

ConfigMap

cm.yaml

apiVersion: v1
kind: ConfigMap
metadata:
  name: watchalert
  namespace: default
data:
  config.yaml: |
    Server:
      port: "9001"
      # 定义相同的Group之间发送告警通知的时间间隔(s), 组内有告警就一起发出, 没有则单独发出.
      # 第一次产生的告警, 等待10s（为了防止在等待期间,还没有推送告警消息期间这时告警消失了触发了恢复消息）
      groupWait: 10
      # 第二次产生的告警, 等待120s（为了保证告警聚合性相同时间段的告警一起发送）
      groupInterval: 120
      # 告警恢复等待时间，1m（为了防止在告警触发恢复后紧接着再次触发告警条件）
      recoverWait: 1

    MySQL:
      host: 127.0.0.1
      port: 3306
      user: root
      pass: semaik1023
      dbName: watchalert
      timeout: 10s

    Redis:
      host: 127.0.0.1
      port: 6379
      pass: ""

    Jwt:
      # 失效时间
      expire: 18000
