一：用途
Harbor是一个用于存储和分发Docker镜像的企业级Registry服务器。
二：安装docker-ce
环境：阿里云轻量应用服务器CentOS 7.3
这里通过yum Docker源仓库安装：
①安装yum 管理依赖包
sudo yum install-y yum-utils device-mapper-persistent-data lvm2②添加Docker 源仓库
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo③安装Docker CE
sudo yum install docker-ce docker-ce-cli containerd.io三：安装docker-compose
参考这篇博客：https://www.cnblogs.com/wucaiyun1/p/11811112.html
四：安装harbor
https://github.com/goharbor/harbor/blob/master/docs/installation_guide.md
①下载harbor
wget https://storage.googleapis.com/harbor-releases/harbor-offline-installer-v1.6.1.tgz或者到github releases下载
https://github.com/goharbor/harbor/releases
②配置安装(http方式)
[root@iZuf6hcb8yumasfp52oemxZ ailala]# tar -xf harbor-offline-installer-v1.6.1.tgz
[root@iZuf6hcb8yumasfp52oemxZ ailala]# cd harbor
[root@iZuf6hcb8yumasfp52oemxZ harbor]# vi harbor.yml
[root@iZuf6hcb8yumasfp52oemxZ harbor]# ./prepare[root@iZuf6hcb8yumasfp52oemxZ harbor]# ./install③登录
五：上传镜像到harbor仓库
在本机配置harbor仓库http可信
/etc/docker/daemon.json中添加“"insecure-registries":["reg.slito.com"]”，不然会报错，默认是走https的，重启docker；
登录harbor仓库
[root@iZuf6hcb8yumasfp52oemxZ harbor]# docker login fixedbug.work:88
