在企业内部使用Docker容器来部署使用是我们都会自己搭建一个自己的私有Docker Registry 仓库；网上有很多种方法，这里介绍使用 Vmwar 公司开源的 企业级的 Docker Registry 来管理项目；主要它还带中文。
环境要求：
[root@reg harbor]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
Python 2.7.5 #系统自带
Docker version 1.10.3
docker-compose version 1.10.1
安装软件：
curl -fsSL https://get.docker.io | bash
yum install python-pip -y
pip install -i https://pypi.douban.com/simple/ docker-compose
修改docker配置文件：
修改docker的默认仓库：
vim /etc/sysconfig/docker
OPTIONS='--selinux-enabled -H 0.0.0.0:2375 -H unix:///var/run/docker.sock --insecure-registry 10.0.10.88'
重启docker服务：systemctl restart docker.service
harbor离线安装包下载：[303M大小]
https://github.com/vmware/harbor/releases/download/0.5.0/harbor-offline-installer-0.5.0.tgz
[root@reg ~]# tar xf harbor-offline-installer-0.5.0.tgz -C /opt/
[root@reg ~]# cd /opt/harbor/
[root@reg harbor]# ls
common docker-compose.yml harbor.0.5.0.tgz harbor.cfg install.sh LICENSE NOTICE prepare
1、修改配置文件harbor.cfg
hostname= reg.docker.tb #本机外网IP或域名，该地址供用户通过UI进行访问，不要使用127.0.0.1
ui_url_protocal = https #配置访问协议,默认为http;如果要启动SSl认证为:https
email_server = smtp.qq.com #配置邮件服务器地址
email_server_port =25 #邮件服务器端口
email_username= xxxxx #用户
email_password = xxxx #密码
email_from = admin@simpletour.com #发件人地址
email_ssl = false #是否进行ssl加密
harbor_admin_password = Harbor12345 #harbor admin的初始密码
auth_mode = db_auth #harbor认证模式，默认为db_auth，本地mysql，也可以配置ldap认证
#ldap认证方式
ldap_url= ldaps://ldap.mydomain.com
ldap_basedn = ou=people,dc=mydomain,dc=com
ldap_uid = uid
ldap_scope = 3
#数据库密码
db_password = root123
self_registration = on
use_compressed_js = on
max_job_workers = 3 #最大工作进程
token_expiration = 30 #token过期时间，默认为30分钟
verify_remote_cert = on
customize_crt = on
#显示的认证及组织信息
crt_country = CN
crt_state = State
crt_location = CN
crt_organization = organization
crt_organizationalunit = organizational unit
crt_commonname = example.com
crt_email = example@example.com
#可选的https证书配置地址
ssl_cert = /root/cert/reg.docker.tb.crt
ssl_cert_key = /root/cert/reg.docker.tb.key
2、上面启动了SSL认证，所以要创建一个CA证书[实验环境自己创建，线上环境购买就好]
创建相应目录：
mkdir -p /root/cert/
进入/data/cert目录下，创建CA认证：
localdomain=reg.docker.tb
以下根据自己情况修改：
openssl req -nodes -subj "/C=CN/ST=GuangDong/L=DongGuan/CN=$localdomain" -newkey rsa:2048 -keyout $localdomain.key -out $localdomain.csr
openssl x509 -req -days 3650 -in $localdomain.csr -signkey $localdomain.key -out $localdomain.crt
openssl x509 -req -in $localdomain.csr -CA $localdomain.crt -CAkey $localdomain.key -CAcreateserial -out $localdomain.crt -days 10000
执行安装./install.sh
[root@reg harbor]# ./install.sh

----Harbor has been installed and started successfully.----
Now you should be able to visit the admin portal at http://reg.docker.tb.
For more details, please visit https://github.com/vmware/harbor .
注：默认执行上面安装后会自动启动服务；
此时打开网页访问reg.docker.tb时就会提示ssl不安全的连接，说明ssl添加成功；但是在命令行登陆docker仓库时不成功的。[用Ip登陆则成功]
[root@reg harbor]# docker login reg.docker.tb
Username (upload): admin
Password:
Email (msf6300@163.com): admin@example.com
Error response from daemon: invalid registry endpoint https://reg.docker.tb/v0/: unable to ping registry endpoint https://reg.docker.tb/v0/
v2 ping attempt failed with error: Get https://reg.docker.tb/v2/: x509: certificate is valid for server, not reg.docker.tb
v1 ping attempt failed with error: Get https://reg.docker.tb/v1/_ping: x509: certificate is valid for server, not reg.docker.tb. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry reg.docker.tb` to the daemon's arguments. In the case of HTTPS, if you have access to the registry's CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/reg.docker.tb/ca.crt
解决方法：停止服务：
[root@reg harbor]# docker-compose down
创建对应目录：
mkdir -p /etc/docker/certs.d/reg.docker.tb
cp /data/cert/reg.docker.tb.crt /etc/docker/certs.d/reg.docker.tb/ca.crt
启动服务：
[root@reg harbor]# docker-compose up -d
再次登陆,成功了：
[root@reg harbor]# docker login reg.docker.tb
Username: admin
Password:
Email: admin@example.com
WARNING: login credentials saved in /root/.docker/config.json

查看配置文件的信息：[保存了用户名，仓库地址和加密码MD5密码]
登陆过的用户信息都会保存在： /root/.docker/config.json以json格式保存。
本机上传镜像
[root@harbor harbor]# docker push reg.docker.tb/test/ubuntu
The push refers to a repository [reg.docker.tb/test/ubuntu]

本机拉取镜像：
[root@harbor harbor]# docker pull reg.docker.tb/test/ubuntu:latest

Status: Downloaded newer image for reg.docker.tb/test/ubuntu:latest
此时，如果其它的Docker主机[centos6系统]要使用此仓库，只需要把上面的ca.crt复制到docker主机的： /etc/docker/certs.d/reg.docker.tb/目录下；并且要修改一下Docker配置文件的仓库地址：/etc/sysconfig/docker
[root@node2 certs.d]# grep "insecure-registry" /etc/sysconfig/docker
INSECURE_REGISTRY='--insecure-registry reg.docker.tb'
因为这里使用了一个域名，我同时也在/etc/hosts文件中添加了对应的解析；把docker服务重启一下即可；
注：如果你的客户端是Centos7系统，添加的参数:/usr/lib/systemd/system/docker.service
在ExecStart行后面添加仓库地址：
ExecStart=/usr/bin/docker daemon -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock --insecure-registry reg.docker.tb
