上篇文章了解到了如何使用新的版本的harbor，这篇文章来了解一下harbor架构的组成和运行时各个组件的使用方式。
[root@liumiao harbor]# docker-compose psName Command State Ports
------------------------------------------------------------------------------------------------------------------------------
harbor-adminserver /harbor/start.sh Up
harbor-db /usr/local/bin/docker-entr ... Up 3306/tcp

[root@liumiao harbor]# | 组件 | 说明 | 实现 |
|---|---|---|
| Proxy | 用于转发用户的请求到registry/ui/token service的反向代理 | nginx：使用nginx官方镜像进行配置 |
| Registry | 镜像的push/pull命令实施功能 | registry：使用registry官方镜像 |
| Database | 保存项目/用户/角色/复制策略等信息到数据库中 | harbor-db：Mariadb的官方镜像用于保存harbor的数据库信息 |
| Core Service: UI/token/webhook | 用户进行镜像操作的界面实现，通过webhook的机制保证镜像状态的变化harbor能够即使了解以便进行日志更新等操作，而项目用户角色则通过token的进行镜像的push/pull等操作 | harbor-ui等 |
| Job services | 镜像复制，可以在harbor实例之间进行镜像的复制或者同步等操作 | harbor-jobservice |
| Log collector | 负责收集各个镜像的日志信息进行统一管理 | harbor-log：缺省安装下日志的保存场所为/var/log/harbor |
proxy就是使用nginx作为反向代理，而整个的核心则在于nginx的设定文件，通过如下的设定文件可以清楚的看到harbor所解释的将各个其他组件集成在一起的说明内容，而实际的实现也基本上就是靠nginx的设定。

[root@liumiao harbor]# 可以看到使用的是MariaDB 10.2.14, harbor的数据库名称为registry
[root@liumiao harbor]# docker exec -it harbor-db sh
sh-4.3# mysql -uroot -pliumiaopw

networks:harbor:external: false[root@liumiao harbor]# 在前一篇文章的例子中我们使用默认的80口作为harbor的端口，如果希望进行更改（比如改为8848），按照如下步骤进行修改即可
| 步骤 | 详细说明 |
|---|---|
| Step 1 | 修改l中80：80端口映射，改为8848：80.(https方式修改8848：443) |
| Step 2 | 修改hostname信息，将端口号带上，改为192.168.163.128:8848 |
| Step 3 | 停止harbor：docker-compose down |
| Step 4 | 执行prepare更新设定： ./prepare |
| Step 5 | 启动harbor：docker-compose up -d |
可以通过查看数据库的properties或者api/systeminfo来确认harbor设定项目的详细信息
