Harbor 是一个用于存储和分发 Docker 镜像的企业级 Registry 服务器，由 vmware
开源，其通过添加一些企业必需的功能特性，例如安全、标识和管理等，扩展了开源
Docker Distribution。作为一个企业级私有 Registry 服务器，Harbor 提供了更
好的性能和安全。提升用户使用 Registry 构建和运行环境传输镜像的效率。Harbor
支持安装在多个 Registry 节点的镜像资源复制，镜像全部保存在私有 Registry 中，
确保数据和知识产权在公司内部网络中管控，另外，Harbor 也提供了高级的安全
特性，诸如用户管理，访问控制和活动审计等。
一. Harbor 功能介绍
基于角色的访问控制：用户与 Docker 镜像仓库通过“项目”进行组织管理，一个用户可
以对多个镜像仓库在同一命名空间（project）里有不同的权限。
镜像复制：镜像可以在多个 Registry 实例中复制（同步）。尤其适合于负载均衡，高
可用，混合云和多云的场景。
图形化用户界面：用户可以通过浏览器来浏览，检索当前 Docker 镜像仓库，管理项目
和命名空间。
AD/LDAP 支：Harbor 可以集成企业内部已有的 AD/LDAP，用于鉴权认证管理。
审计管理：所有针对镜像仓库的操作都可以被记录追溯，用于审计管理。
国际化：已拥有英文、中文、德文、日文和俄文的本地化版本。更多的语言将会添加进来。
RESTful API - RESTful API：提供给管理员对于 Harbor 更多的操控, 使得与其它管
理软件集成变得更容易。
部署简单：提供在线和离线两种安装工具， 也可以安装到 vSphere 平台(OVA 方
式)虚拟设备。

nginx： harbor的一个反向代理组件，代理registry、ui、token等服务。这个代理会转发harbor web和docker client的各种请求到后端服务上。harbor-adminserver：harbor系统管理接口，可以修改系统配置以及获取系统信息。
harbor-db： 存储项目的元数据、用户、规则、复制策略等信息。
harbor-jobservice： harbor里面主要是为了镜像仓库之前同步使用的。
harbor-log： 收集其他harbor的日志信息。
harbor-ui： 一个用户界面模块，用来管理registry。
registry： 存储docker images的服务，并且提供pull/push服务。
redis： 存储缓存信息
webhook： 当registry中的image状态发生变化的时候去记录更新日志、复制等操作。
token service： 在docker client进行pull/push的时候负责token的发放。
二. Harbor 安装
Server1 安装 Docker
[root@docker-server-node1 ~]# wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[root@docker-server-node1 ~]# yum install docker-ce -y
[root@docker-server-node1 ~]# systemctl start docker
Server2 安装 Docker
[root@docker-server-node2 ~]# wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[root@docker-server-node2 ~]# yum install docker-ce -y
[root@docker-server-node2 ~]# systemctl start docker
下载 Harbor 安装包
本次使用当前 harbor 1.7.6 离线安装包，具体名称为
harbor-offline-installer-v1.7.6.tgz
离线安装包
推荐使用离线完整安装包
[root@docker-server-node1 ~]# cd /usr/local/src/
[root@docker-server-node1 src]# wget https://storage.googleapis.com/harbor-releases/release-1.7.0/harbor-offline-installer-v1.7.5.tgz
在线安装包
不推荐使用在线安装包安装，需要从网络下载全部所需文件
[root@docker-server-node1 src]# wget
https://github.com/vmware/harbor/releases/download/v1.7.5/harbor-online-
installer-v1.10.1.tgz
三.配置 Harbor
3.1 解压并编辑 harbor.cfg
[root@docker-server-node1 src]# tar -xf harbor-offline-installer-v1.7.6.tgz
[root@docker-server-node1 src]# ln -sv /usr/local/src/harbor /usr/local/
‘/usr/local/harbor’ -> ‘/usr/local/src/harbor’[root@docker-server-node1 src]# cd /usr/local/harbor/

五.实现 harbor 高可用
- Harbor 有两种高可用实现方式：
- 基于共享存储实现
- 基于镜像复制实现
Harbor 支持基于策略的 Docker 镜像复制功能，这类似于 MySQL 的主从同步，
其可以实现不同的数据中心、不同的运行环境之间同步镜像，并提供友好的管理
界面，大大简化了实际运维中的镜像管理工作，已经有用很多互联网公司使用
harbor 搭建内网 docker 仓库的案例，并且还有实现了双向复制的案列。
5.1 新部署一台 harbor 服务器
Server1:192.168.100.10
此处 Server1 为从 Harbor，主 Harbor 为 Server2:192.168.100.19
主在向从复制镜像时，需要从 Harbor 有相同的镜像仓库名。此实验都使
用默认的 library。

从 Harbor 部署好的样子:
5.3 在主 Harbor 默认的 library 参考添加复制规则
从 harbor 的 library 仓库，与主 harbor 仓库名称 library 一致。当然，
也可以创建新的仓库，主从的仓库名保持一致即可。
在主 Harbor Server2:192.168.100.19 的仓库管理添加从 Harbor 作为目标:
在主 Harbor Server2:192.168.100.19 的 library 添加复制规则:
5.4 在从 harbor 仓库下载镜像使用
从 Harbor 上将同步的 alpine 镜像 pull 下来测试
[root@docker-server-node1 ~]# docker pull 192.168.100.10/library/alpine:latest
latest: Pulling from library/alpine

六.实现 harbor 双向同步
在从 Harbor(192.168.100.10)创建复制规则，将上传到从 Harbor 的镜像同步到
主 Harbor(192.168.100.19)，两边都在 library 仓库创建复制规则。
