    安装harbor

    [root@harbor2 harbor]# ./install.sh

    可以手工启动 harbor

    docker-compose start 

    docker-compose stop

    查看harbor的web界面，默认是80端口，默认用户名 admin/Harbor12345   #可以在harbor.cfg 配置文件中进行修改

     配置docker客户端即docker的容器的宿主机使用harbor镜像仓库

    [root@localhost ~]# vi /usr/lib/systemd/system/docker.service 

    修改如下框所示列

    修改docker的启动脚本  加上harbor的ip地址

 4 After=network-online.target firewalld.service
 5 Wants=network-online.target

32 [Install]
33 WantedBy=multi-user.target
    docker.service

    重新启动docker

    systemclt restart docker

     

    登录 harbor

    登录成功后会在当前用户的家目录下 ，生成一个隐藏文件，用来存放验证信息。

     docker客户端上传镜像到harbor

    [root@localhost ~]# docker images

    [root@localhost ~]# docker tag haproxy:v1 192.168.153.135/webimage/haproxy:v1

    [root@localhost ~]# docker push 192.168.153.135/webimage/haproxy:v1

     

    在另一个docker客户端点击pull命令  复制  pull命令 ，从docker客户端拉取harbor仓库的镜像

    两个 harbor仓库的同步

     添加另外一个harbor仓库

    如果 打开 harbor web界面  报 503 错误的话  

    在 harbor的安装目录下

    重启harbor

    docker-compose stop

    docker-compose start

    查看80 端口

    ss -tnl

    查看防火墙是否关闭

    如果 TEST CONNECTION 不通过的话  查看防火墙问题

    在项目中添加项目，上传镜像

     [root@192 ~]# docker images

    标记镜像  并把镜像同步到harbor中

    [root@192 ~]# docker tag nginx-base:v1 192.168.153.140/webimage/nginx-base:v1

    [root@192 ~]# docker push 192.168.153.140/webimage/nginx-base:v1

    在项目中  编辑harbor同步规则

    在此harbor界面中看到   同步日志完成

    在 另外的harbor中查看  镜像同步情况

    在界面上显示同步成功
