Harbor介紹

Harbor是VMware公司開源的企業級Docker Registry項目
Harbor的優點

基於角色控制docker

基於鏡像的複製策略數據庫

支持LDAP目錄服務/AD域服務json

圖像刪除和垃圾收集vim

圖形UI（能夠訪問Web界面）後端

審計

RESTful API

Harbor架構組成

Proxy：

經過一個前置的反向代理統一接收瀏覽器、Docker客戶端的請求， 並將請求轉發給後端不一樣的服務

Registry：倉庫

負責儲存Docker鏡像， 並處理docker push(上傳)/pull(下載)命令

Core services：

Harbor的核心功能，包括UI、webhook、 token(令牌) 服務

Database：mysql

爲core services提供數據庫服務

Log collector：

負責收集其餘組件的log,供往後進行分析

Docker私有倉庫架構拓撲：

在這裏插入圖片描述

過程介紹：

訪問倉庫以前先用帳戶訪問Core service，UI支持web界面，首次成功登陸後token發身份驗證令牌，後期用戶直接使用分發的令牌訪問database倉庫，查看鏡像，若是沒有就直接返回無鏡像名稱（hub公共倉庫下載），若是存在，使用webhook回調，倉庫發送信息返回客戶端，最終全部的操做信息都會記錄到log collector中

名詞解釋

webhook：

微服務當中的回調機制

token(令牌)生成方式：

1.服務器給予序列號，後面直接經過序列號找服務器驗證，方可經過

2.基於客戶端的MAC地址，生成字符串，每次傳參數時須要帶上MAC地址，此時服務器會去驗證MAC地址，若以前已驗證過則可直接經過

database：

存儲用戶信息，包括權限，鏡像的屬性信息

部署Harbor服務

下載Harbor安裝程序：
wget http://harbor.orientsoft.cn/harbor-1.2.2/harbor-offline-installer-v1.2.2.tgz
tar xvf harbor-offline-installer-v1.2.2.tgz -C /usr/local
配置Harbor參數文件：

參數位於文件/usr/local/harbor/harbor.cfg

Harbor所須要參數：

hostname 、ui_url_protocol、max_job_workers

db_password、customize_crt、ssl_cert、ssl_cert_key

secretkey_path

Harbor可選參數：

電子郵件設置、harbour_admin_password、auth_mode

self_registration、token_expiration

project_creation_restriction、verify_remote_cert

啓動並安裝Harbor：

[root@localhost harbor]# sh /usr/local/harbor/install.sh

查看Harbor啓動鏡像並訪問管理頁面
建立一個新項目：

首先登陸Harbor

鏡像打tag

上傳鏡像到Harbor

以上操做都是在Harbor本地，若是其餘客戶端操做Harbor，就會報錯，須要在Harbor之外的其餘Docker客戶端修改配置，而後重啓Docker
