背景：隨着工作的不斷推進，鏡像越來越多，部署的機器越來越多，每次部署都需要build一次鏡像非常耗時，尤其是在樹莓派上build帶有pip3 install pandas的鏡像，往往耗時一個小時（雖然apt install python3-pandas快，但目前版本僅支持到0.25.3,1.0.0+的新接口並不支持，如pandas.json_normalize），因而就萌生了將鏡像上傳至鏡像倉庫中，而鏡像倉庫分爲公共倉庫和私有倉庫，受限於隱私性，只能考慮私有倉庫，目前的倉庫部署方式：
部署：
服務器主機：
>>> docker pull registry:2
>>> docker run -d -p 5000:5000 --restart always --name registry registry:2
客戶主機：
# 爲了使http可用，需添加信任ip
>>> sudo vim /etc/docker/daemon.json
{ "insecure-registries":["服務器主機ip:5000"] }
>>> service docker restart
上傳
>>> docker tag ubuntu:latest 服務器主機ip/test/ubuntu:20.04
>>> docker push 服務器主機ip/test/ubuntu:20.04
可以看到，非常簡單，但是也非常簡陋，存在問題：
- 缺乏權限控制，理論上只要知道ip、端口、項目名稱、倉庫名稱就能獲取；
- 無圖形化界面，管理繁瑣
爲了解決上述問題，引入Harbor，一個由VMware公司開源的容器鏡像管理工具，貌似是中國團隊開發的，因而原生支持中文，廢話不多說，安裝部署使用方式如下：
安裝環境：
- CentOS 7.8.2003
- Docker 19.03.11
- Docker compose 1.26.0
安裝過程參考：https://juejin.im/post/5d9c2f25f265da5bbb1e3de5

docker-compose version 1.26.0, build d4451659
# 安裝
# 下載在線安裝包
>>> wget https://storage.googleapis.com/harbor-releases/harbor-online-installer-v2.0.0.tgz

>>> cd harbor
安裝：
# 編輯配置文件
>>> vim harbor.yml.tmpl
# 修改hostname
hostname: 服務器ip
# 將https註釋掉，以關閉https支持
# https related config
#https:
# # https port for harbor, default is 443
# port: 443
# # The path of cert and key files for nginx
# certificate: /your/certificate/path
# private_key: /your/private/key/path
# 默認的管理員賬號密碼也可以修改
# 安裝
>>> mv harbor.yml.tmpl harbor.yml

Harbor系統運維
在docker-compose.yml目錄下執行
- Stopping Harbor:
#docker-compose stop
Stopping harbor-jobservice ... done
Stopping nginx ... done
Stopping harbor-core ... done
Stopping redis ... done
Stopping registry ... done
Stopping harbor-portal ... done
Stopping registryctl ... done
Stopping harbor-db ... done
Stopping harbor-log ... done
- Restarting Harbor after stopping:
#docker-compose start
Starting log ... done
Starting registry ... done
Starting registryctl ... done
Starting postgresql ... done
Starting portal ... done
Starting redis ... done
Starting core ... done
Starting jobservice ... done
Starting proxy ... done
- To change Harbor’s configuration, first stop existing Harbor instance and update harbor.cfg.
Then run prepare script to populate the configuration. Finally re-create and start Harbor’s instance:
# docker-compose down
# vim harbor.cfg
# ./prepare
# docker-compose up -d
- Removing Harbor’s containers while keeping the image data and Harbor’s database files on the file system:
# docker-compose down
- Removing Harbor’s database and image data (for a clean re-installation):
# rm -r /data/database
# rm -r /data/registry
- 修改監聽端口（默認監聽80端口）
Configuring Harbor listening on a customized port.
By default, Harbor listens on port 80(HTTP) and 443(HTTPS, if configured) for both admin portal and docker commands, you can configure it with a customized one.
For HTTP protocol
- Modify docker-compose.yml，Replace the first “80” to a customized port, e.g. 8888:80.
# vim docker-compose.yml
proxy:
image: library/nginx:1.11.5
restart: always
volumes:
- ./config/nginx:/etc/nginx
ports:
- 8888:80
- 443:443
depends_on:
- mysql
- registry
- ui
- log
logging:
driver: "syslog"
options:
syslog-address: "tcp://127.0.0.1:1514"
tag: "proxy"
- Modify harbor.cfg, add the port to the parameter “hostname”.
# vim harbor.cfg
hostname = 10.90.5.105:8888
- Re-deploy Harbor refering to previous section.
# docker-compose down
# ./prepare
# docker-compose up -d
