docker最重要的三个概念：docker镜像，docker容器，以及docker仓库。docker镜像是是docker虚拟化中最基础的部分，通过docker镜像来启动一个docker容器，docker 容器是docker虚拟化的产物。
而docker仓库是用来存储docker镜像的地方，分为公有仓库和私用仓库。默认的公共仓库，对外开放、免费或者付费使用，企业测试环境和生产环境推荐自建私有仓库。私有仓库的特点：安全、可靠、稳定、高效，可以根据自身的业务体系进行灵活升级和管理。
使用harbor做为docker仓库的优点有：
安全，可靠，性能稳定。
一、部署harbo
#安装Docker-Compose
[root@localhost src]# yum install epel-release -y
[root@localhost src]# yum install python-pip -y
[root@localhost src]# pip install --upgrade pip
[root@localhost src]# curl -L https://github.com/docker/compose/releases/download/1.18.0/run.sh > /usr/local/bin/docker-compose
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 643 100 643 0 0 1267 0 --:--:-- --:--:-- --:--:-- 1268
[root@localhost src]# chmod +x /usr/local/bin/docker-compose
[root@localhost src]# ls /usr/local/bin/docker-compose
/usr/local/bin/docker-compose
#下载harbor 安装harbor
[root@localhost src]# cd /usr/src
[root@localhost src] wget -c https://storage.googleapis.com/harbor-releases/release-1.7.0/harbor-offline-installer-v1.7.0.tgz
[root@localhost src]# ls
debug harbor harbor-offline-installer-v1.7.0.tgz kernels
[root@localhost src]# tar -zxvf harbor-offline-installer-v1.7.0.tgz
[root@localhost /]# cd /usr/src/harbor
[root@localhost harbor]# ./install.sh
?执行harbor安装脚本，会自动下载harbor与harbor相关docker镜像，配置，启动harbor容器
?
浏览器输入主机地址，即可打开harbor登录窗口
默认账号：admin?默认密码：Harbor12345，完成登录
?二、使用Harbor
1、创建私有仓库用户名，并且设置密码，
用户管理-创建用户
2、把创建用户绑定library仓库
项目-library-成员，添加刚才创建的用户
?
?docker login，确认使用创建用户登录
[root@localhost src]# docker login 192.168.139.132
Username: caixin
Password:
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@localhost src]# 最后，通过push，把镜像上传到harbor仓库
[root@localhost src]# docker images

[root@localhost src]#例如，把上面nginx,mysql,php三个镜像上传到harbor仓库
上传之前，仓库内容为空，啥也没有
?首先，修改TAG，tag号修改为如下格式：
192.168.139.132/library/nginx:
192.168.139.132/library/mysql:
192.168.139.132/library/php:

[root@localhost src]# 最后查看镜像上传情况，是否上传到Harbor仓库
如果要使用harbor仓库里面的镜像，只需要到登录到仓库，打开对应镜像，复制pull命令到linux里执行即可。
