nexus 数据库备份任务webhook 通知

nexus 的数据库备份是比较重要的，可以方便我们在故障的是时候进行应用恢复。
以下使用benthos 组件进行nexus 数据库备份事件的应用通知处理

环境准备

使用docker-compose 运行

• docker-compose.yaml 文件

version: "3"
services:
  nexus:
    image: sonatype/nexus3
    ports:
    - "8081:8081"
    volumes:
    - ./nexus-data:/nexus-data
    - ./backup/:/backup/
  benthos:
    image: jeffail/benthos
    volumes:
    - "./webhook.yaml:/benthos.yaml"
    ports:
    - "4195:4195"
  smtp2http:
    image: dalongrong/smtp2http
    command: --listen=:25 --webhook=http://benthos:4195/ --strict=false

• 启动

docker-compose up -d

• 说明
  如果出现权限的问题，可以直接设置777 权限，简单（但是不是很合理）chmod 777 backup nexus-data

配置webhook 功能

使用全局webhook

• 配置全局audit webhook

注意地址使用docker-compose 内置的服务发现功能，实际上就是benthos 服务的信息

• 配置db exporter 任务
  如下

运行任务&&查看效果

• 启动任务
  直接点击run运行配置的db exporter 任务
• 效果

说明

我们可以用这个功能,使用备份好的数据，以及通知，进行nexus 备份机器的启动还原，方便在故障出现的时候，快速恢复系统，但是有一个要就，就是仓库数据
也同时做了备份，或者使用了共享存储
