再探docker私有倉庫，harbor！
- harbor的優點
- harbor核心組件
- 部署harbor
- harbor中的七個容器：
harbor的優點
- 基于角色控制
- 基于鏡像的復制策略
- 圖形UI
- 審計
- RESTful API
- 影像洗掉和垃圾收集
- 支持LDAP/AD
harbor核心組件
- proxy：通過一個前置的反向代理統一接受瀏覽器、Docker客戶端的請求，并將請求轉發給后端不同的服務
- Core services：Harbor的核心功能，包括UI、webhook、token服務
webhook：是一種反向API機制，類似于觸發器
token：令牌，提供身份驗證服務 - Database：為core services提供資料庫服務
- Log collector：負責收集其他組件的log，供日后進行分析
- Registry：復制儲存Docker鏡像，并處理docker push/pull命令
部署harbor
- 安裝harbor
[root@server ~]# tar zxf harbor-offline-installer-v1.2.2.tgz -C /usr/local/
[root@server ~]# chmod +x docker-compose
[root@server ~]# cp docker-compose /usr/local/bin/
- 配置harbor引數并查看容器
5 hostname = 192.168.1.101
56 ##The initial password of Harbor admin, only works for the first time when Harbor starts.
57 #It has no effect after the first launch of Harbor.
58 #Change the admin password from UI after launching Harbor.
59 harbor_admin_password = Harbor12345 //定義了admin的密碼
[root@server harbor]# docker ps -a //發現多了幾個容器

- 想要使用不是本地的ip地址推送鏡像，需要修改
[root@server docker]# vim daemon.json
