Harbor 2.0.0安装及使用

背景：随着工作的不断推进，镜像越来越多，部署的机器越来越多，每次部署都需要build一次镜像非常耗时，尤其是在树莓派上build带有pip3 install pandas的镜像，往往耗时一个小时（虽然apt install python3-pandas快，但目前版本仅支持到0.25.3,1.0.0+的新接口并不支持，如pandas.json_normalize），因而就萌生了将镜像上传至镜像仓库中，而镜像仓库分为公共仓库和私有仓库，受限于隐私性，只能考虑私有仓库，目前的仓库部署方式：

部署：

服务器主机：

>>> docker pull registry:2
>>> docker run -d -p 5000:5000 --restart always --name registry registry:2

客户主机：

# 为了使http可用，需添加信任ip
>>> sudo vim /etc/docker/daemon.json
{ "insecure-registries":["服务器主机ip:5000"] } 
>>> service docker restart

上传

>>> docker tag ubuntu:latest 服务器主机ip/test/ubuntu:20.04
>>> docker push 服务器主机ip/test/ubuntu:20.04

---

可以看到，非常简单，但是也非常简陋，存在问题：

1. 缺乏权限控制，理论上只要知道ip、端口、项目名称、仓库名称就能获取；
2. 无图形化界面，管理繁琐

为了解决上述问题，引入Harbor，一个由VMware公司开源的容器镜像管理工具，貌似是中国团队开发的，因而原生支持中文，废话不多说，安装部署使用方式如下：
安装环境：

• CentOS 7.8.2003
• Docker 19.03.11
• Docker compose 1.26.0

Harbor系统运维

在docker-compose.yml目录下执行

• 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

• 修改监听端口（默认监听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

1. 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"

2. Modify harbor.cfg, add the port to the parameter “hostname”.

# vim harbor.cfg

hostname = 10.90.5.105:8888

3. Re-deploy Harbor refering to previous section.

# docker-compose down
# ./prepare
# docker-compose up -d
