Docker搭建Harbor公开仓库的方法示例

上一篇博文讲到了Registry私有仓库，今天配置一下Harbor仓库，Harbor呢可以作为公开仓库，也可以作为私有仓库，今天就来配置一下Harbor如何实现公开仓库和私有仓库。

关于Registry公开仓库请访问博文：部署Docker私有仓库Registry

Registry和Harbor的区别

Registry：是一个私有镜像仓库，图形化支持较差，小型企业使用；
Harbor：支持可视化管理，支持私有仓库和公有仓库，支持镜像的管理控制；

Docker Harbor的优点

VMWare公司的开源镜像管理解决方案；
支持图形化管理；
方便访问和配置；
方便镜像访问控制；
支持镜像负责策略；
审计统计用户访问镜像使用情况；

Docker Harbor依赖的程序

Python；
安装Docker；
Docker Compose；

一、搭建Harbor仓库

案例描述：

两台CentOS7.4，一台服务器端，一台客户端（测试使用）；

两台服务器都要安装Docker服务，我这里Docker版本是19.03.9版本；

关于Docker容器的安装请访问：安装Docker.v19。03.9版本

1、配置Docker Compose

访问道云官网，找到安装Docker Compose，复制命令到Docker服务器端：道云

[root@centos01 ~]# curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.5/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose 

[root@centos01 ~]# chmod +x /usr/local/bin/docker-compose 
[root@centos01 ~]# docker-compose -v   
docker-compose version 1.25.5, build 8a1c60f6

2、配置Docker Harbor公开仓库

1）打开Github官网

打开Github官网搜索harbor，再点击goharbor/harbor，再点击“releases”，根据自己所需，下载相应的版本，上传至服务器（网址如下：https://github.com/goharbor/harbor/releases 也可下载在线安装的包，我没试过，可自行尝试），如下：

2）配置Harbor仓库

harbor-online-installer-v1.9.1.tgz  
[root@centos01 ~]# tar zxvf harbor-online-installer-v1.9.1.tgz -C /usr/local/
  
[root@centos01 ~]# cd /usr/local/harbor/  
[root@centos01 harbor]# cp harbor.yml harbor.yml.bak 
[root@centos01 harbor]# vim harbor.yml  
 5 hostname: 192.168.100.10   

 8 http:   
10 port: 80  
27 harbor_admin_password: Harbor12345  
[root@centos01 harbor]# ./install.sh   
[Step 0]: checking installation environment ...

Note: docker version: 19.03.9

Note: docker-compose version: 1.25.5

✔ ----Harbor has been installed and started successfully.----

Now you should be able to visit the admin portal at http://www.benet.com .
For more details, please visit https://github.com/goharbor/harbor .
   
[root@centos01 ~]# vim /usr/lib/systemd/system/docker.service 
14 ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock --insecure-registry 192.168.100.10:80
 
[root@centos01 harbor]# systemctl daemon-reload   
[root@centos01 harbor]# systemctl restart docker    
[root@centos01 harbor]# docker-compose stop    
[root@centos01 harbor]# docker-compose start     
[root@centos01 harbor]# netstat -anptu |grep 80 
tcp6  0  0 :::80     :::*     LISTEN  23473/docker-proxy

3）安装完成浏览器访问Harbor仓库

4）创建一个公开仓库

5）确保image公开仓库已经创建成功

6）Docker服务器端登录Harbor仓库

[root@centos01 ~]# docker login -uadmin -pHarbor12345 192.168.100.10:80 
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded  
[root@centos01 ~]# docker tag tomcat:latest 192.168.100.10:80/image/nginx:nginx 
   
[root@centos01 ~]# docker push 192.168.100.10:80/image/nginx:nginx
  
[root@centos01 ~]# docker logout 192.168.100.10:80 
Removing login credentials for 192.168.100.10:80

7）Harbor查看镜像是否上传成功

3、配置Docker客户端



1）修改配置文件加载Docker Harbor服务器
[root@centos02 ~]# vim /usr/lib/systemd/system/docker.service 
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock --insecure-registry 192.168.100.10:80 
 
[root@centos02 ~]# systemctl daemon-reload  
[root@centos02 ~]# systemctl restart docker  
[root@centos02 ~]# docker login -uadmin -pHarbor12345 192.168.100.10:80 
   
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded 
[root@centos02 ~]# docker pull 192.168.100.10:80/image/nginx:nginx 
 
[root@centos02 ~]# docker images  
REPOSITORY     TAG     IMAGE ID   CREATED    SIZE
192.168.100.10:80/image/nginx nginx    1b6b1fe7261e  7 days ago   647MB

4、创建Harbor私有仓库

1）创建私有仓库

2）创建一个用户

3）将刚创建的private用户添加到private私有仓库中

4）上传镜像到Harbor私有仓库

[root@centos01 ~]# docker tag tomcat:latest 192.168.100.10:80/private/tomcat:tomcat 
  
[root@centos01 ~]# docker login -uprivate -pHarbor12345 192.168.100.10:80 
   
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded 
[root@centos01 ~]# docker push 192.168.100.10:80/private/tomcat:tomcat

5）Harbor查看镜像是否上传成功

6）Docker客户端下载私有仓库中的镜像

[root@centos02 ~]# docker login -uprivate -pHarbor12345 192.168.100.10:80 
  
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded 
[root@centos02 ~]# docker pull 192.168.100.10:80/private/tomcat:tomcat 
   
[root@centos02 ~]# docker images 
REPOSITORY     TAG     IMAGE ID   CREATED    SIZE
192.168.100.10:80/image/nginx  nginx    1b6b1fe7261e  7 days ago   647MB
192.168.100.10:80/private/tomcat tomcat    1b6b1fe7261e  7 days ago   647MB

7）Harbor支持日志统计功能
