Docker搭建私有仓库之Harbor的步骤

[root@dockerA ~]# yum -y install yum-utils device-mapper-persistent-data lvm2
//下载docker-compose工具所需的依赖（部署docker环境时，就可以安装了）
[root@dockerA ~]# curl -L https://github.com/docker/compose/releases/download/1.25.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
//下载docker-compose工具
[root@dockerA ~]# chmod +x /usr/local/bin/docker-compose
[root@dockerA ~]# docker-compose -v      
docker-compose version 1.25.0, build 0a186604
//查看docker-compose工具版本信息，确保已经安装成功

[root@dockerA ~]# wget https://storage.googleapis.com/harbor-releases/release-1.7.0/harbor-offline-installer-v1.7.4.tgz
//下载harbor软件包
[root@dockerA ~]# tar zxf harbor-offline-installer-v1.7.0.tgz -C /usr/local
[root@dockerA ~]# cd /usr/local/harbor/
[root@dockerA harbor]# vim harbor.cfg 
//编写其配置文件，其他版本默认是cfg结尾的，这个版本是yml结尾的，文件内容都一样的
hostname=192.168.45.129         //更改其为本机的IP地址
harbor_admin_password: Harbor12345    
//这一行原本就是存在，不需要自行填写，只需记得它的用户名和密码即可，有需要可以自行进行修改
[root@dockerA harbor]# ./install.sh        //执行安装脚本

[root@dockerA harbor]# vim /usr/lib/systemd/system/docker.service 
//编写docker主配置文件
 ExecStart=/usr/bin/dockerd --insecure-registry 192.168.45.129
 //跟registry差不多，主要harbor配置文件中没有填写端口号，这里也可添加，否则可能会出现错误
[root@dockerA harbor]# systemctl daemon-reload 
[root@dockerA harbor]# systemctl restart docker      //重新启动docker服务
[root@dockerA harbor]# pwd
/usr/local/harbor             //注意目录，必须在这个目录下
[root@dockerA harbor]# docker-compose start
//使用docker-compose工具启动所有容器（因为在重新启动docker时，所有的容器都已经关闭了）
[root@dockerA harbor]# netstat -anpt | grep 80       //确认80端口在监听
tcp6    0   0 :::80          :::*          LISTEN   22871/docker-proxy 

仓库搭建完成后，接着在dockerA（harbor）服务器上上传镜像！
[root@dockerA harbor]# docker login -u admin -p Harbor12345 192.168.45.129 
//指定用户名、密码及harbor服务器地址登录

[root@dockerA ~]# docker tag centos:7 192.168.45.129/test/centos:7
//需要更改镜像名称，test是刚才创建的仓库名称
[root@dockerA ~]# docker push 192.168.45.129/test/centos:7
//向harbor服务器的test仓库上传镜像

[root@dockerB ~]# vim /usr/lib/systemd/system/docker.service 
//编写docker的主配置文件
 13 ExecStart=/usr/bin/dockerd --insecure-registry 192.168.45.129
//指定harbor服务器的IP地址
[root@dockerB ~]# systemctl daemon-reload

[root@dockerB ~]# docker login -u admin -p Harbor12345 192.168.45.129
//登录到harbor服务器
