Apollo - A reliable configuration management system

Build Status GitHub release Maven Central Repo Coverage Status Coverity Scan Build Status codecov.io License

Apollo(阿波罗)是携程框架部门研发的分布式配置中心,能够集中化管理应用不同环境、不同集群的配置,配置修改后能够实时推送到应用端,并且具备规范的权限、流程治理等特性,适用于微服务配置管理场景。

服务端基于Spring Boot和Spring Cloud开发,打包后可以直接运行,不需要额外安装Tomcat等应用容器。

Java客户端不依赖任何框架,能够运行于所有Java运行时环境,同时对Spring/Spring Boot环境也有较好的支持。

.Net客户端不依赖任何框架,能够运行于所有.Net运行时环境。

配置界面

Features

  • 统一管理不同环境、不同集群的配置

    • Apollo提供了一个统一界面集中式管理不同环境(environment)、不同集群(cluster)、不同命名空间(namespace)的配置。
    • 同一份代码部署在不同的集群,可以有不同的配置,比如zk的地址等
    • 通过命名空间(namespace)可以很方便的支持多个不同应用共享同一份配置,同时还允许应用对共享的配置进行覆盖
  • 配置修改实时生效(热发布)

    • 用户在Apollo修改完配置并发布后,客户端能实时(1秒)接收到最新的配置,并通知到应用程序。
  • 版本发布管理

    • 所有的配置发布都有版本概念,从而可以方便的支持配置的回滚。
  • 灰度发布

    • 支持配置的灰度发布,比如点了发布后,只对部分应用实例生效,等观察一段时间没问题后再推给所有应用实例。
  • 权限管理、发布审核、操作审计

    • 应用和配置的管理都有完善的权限管理机制,对配置的管理还分为了编辑和发布两个环节,从而减少人为的错误。
    • 所有的操作都有审计日志,可以方便的追踪问题。
  • 客户端配置信息监控

    • 可以方便的看到配置在被哪些实例使用
  • 提供Java和.Net原生客户端

    • 提供了Java和.Net的原生客户端,方便应用集成
    • 支持Spring Placeholder, Annotation和Spring Boot的ConfigurationProperties,方便应用使用(需要Spring 3.1.1+)
    • 同时提供了Http接口,非Java和.Net应用也可以方便的使用
  • 提供开放平台API

    • Apollo自身提供了比较完善的统一配置管理界面,支持多环境、多数据中心配置管理、权限、流程治理等特性。
    • 不过Apollo出于通用性考虑,对配置的修改不会做过多限制,只要符合基本的格式就能够保存。
    • 在我们的调研中发现,对于有些使用方,它们的配置可能会有比较复杂的格式,如xml, json,需要对格式做校验。
    • 还有一些使用方如DAL,不仅有特定的格式,而且对输入的值也需要进行校验后方可保存,如检查数据库、用户名和密码是否匹配。
    • 对于这类应用,Apollo支持应用方通过开放接口在Apollo进行配置的修改和发布,并且具备完善的授权和权限控制
  • 部署简单

    • 配置中心作为基础服务,可用性要求非常高,这就要求Apollo对外部依赖尽可能地少
    • 目前唯一的外部依赖是MySQL,所以部署非常简单,只要安装好Java和MySQL就可以让Apollo跑起来
    • Apollo还提供了打包脚本,一键就可以生成所有需要的安装包,并且支持自定义运行时参数
