什么是Harbor：

  Harbor是VMware公司开源的企业级Docker Registry项目，其目标是帮助用户迅速搭建一个企业级的Docker registry服务。

  它以Docker公司开源的registry为基础，提供了管理UI，基于角色的访问控制(Role Based AccessControl)，AD/LDAP集成、以及审计日志(Auditlogging) 等企业用户需求的功能，通过添加一些企业必需的功能特性，例如安全、标识和管理等，扩展了开源 Docker Distribution。

  作为一个企业级私有 Registry 服务器，Harbor 提供了更好的性能和安全。提升用户使用 Registry 构建和运行环境传输镜像的效率。

  Harbor 支持安装在多个 Registry 节点的镜像资源复制，镜像全部保存在私有 Registry 中，确保数据和知识产权在公司内部网络中管控。另外，Harbor 也提供了高级的安全特性，诸如用户管理，访问控制和活动审计等。

  Harbor 是由 VMware 中国研发团队负责开发的开源企业级 Docker Registry，不仅解决了我们直接使用 Docker Registry 的功能缺失，更解决了我们在生产使用 Docker Registry 面临的高可用、镜像仓库直接复制、镜像仓库性能等运维痛点。

为什么使用Harbor：

  Docker容器应用的开发和运行离不开可靠的镜像管理，虽然Docker Hub也提供了公共的镜像仓库，但是从安全和效率等方面考虑，部署我们私有环境内的Registry也是非常必要的。

搭建过程

环境准备

系统：Centos7.5
Docker：1.13.1(直接使用的yum install docker进行的安装)
IP地址：192.168.71.106

1、安装docker-compose

#方法一
[root@localhost ~]# curl -L https://github.com/docker/compose/releases/download/1.18.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
[root@localhost ~]# chmod +x /usr/local/bin/docker-compose
[root@localhost ~]# docker-compose version #查看版本
docker-compose version 1.18.0, build 8dd22a9
docker-py version: 2.6.1
CPython version: 2.7.13
OpenSSL version: OpenSSL 1.0.1t  3 May 2016


-------------------------华丽分割线---------------------------------
方法二：
[root@localhost ~]# yum install epel-release -y
[root@localhost ~]# yum install python-pip -y
[root@localhost ~]# pip install -U -i https://pypi.tuna.tsinghua.edu.cn/simple docker-compose 
[root@localhost ~]# docker-compose version
docker-compose version 1.18.0, build 8dd22a9
docker-py version: 2.6.1
CPython version: 2.7.13
OpenSSL version: OpenSSL 1.0.1t  3 May 2016

2、Harbor私有仓库的安装

Harbor在github上的地址：https://github.com/goharbor/harbor/releases
这里我安装当前的最新包1.6.0，分为在线安装和离线安装，这里我使用离线安装包

先下载安装包：

[root@localhost ~]# wget https://storage.googleapis.com/harbor-releases/release-1.6.0/harbor-offline-installer-v1.6.0.tgz

该版本可以从我的的百度云盘下载：https://pan.baidu.com/s/1kVQR4m_sO9LBzdOqPYGKUw 提取码：ghbz

解压安装包：

[root@localhost ~]# tar -zxf harbor-offline-installer-v1.6.0.tgz

配置文件修改：

#解压后，目录下会有harbor.cfg文件，这个文件就是Harbor的配置文件
[root@localhost ~]# cd harbor #进入解压后的目录
[root@localhost harbor]# vim harbor.cfg #对如下信息进行修改
# hostname设置访问地址，可以使用ip、域名，不可以设置为127.0.0.1或localhost
hostname = 192.168.71.106 

# 访问协议，默认是http，也可以设置https，如果设置https，则nginx ssl需要设置on
ui_url_protocol = http

# 启动Harbor后，管理员UI登录的密码，默认是Harbor12345
harbor_admin_password = Harbor12345

修改后保存

启动Harbor：

#修改完配置文件后，在的当前目录执行./install.sh，Harbor服务就会根据当期目录下的docker-compose.yml开始下载依赖的镜像，检测并按照顺序依次启动

#执行安装的命名时，必须要保证docker是启动了的，否则使用systemctl start docker.service命令启动
[root@localhost harbor]# systemctl start docker.service
[root@localhost harbor]# ./install.sh

Harbor启动的服务器(这里排版有点问题，可以复制出去到其他文本中查看)：

[root@localhost harbor]# docker-compose ps
       Name                     Command               State                                Ports

以上启动成功后，可以访问：http://192.168.71.106/harbor/sign-in，界面如下：

使用admin/Harbor12345进行登录，密码是在配置文件中设置，登录成功后进入到管理界面：

从界面可以看出很多功能模块：

• 项目：新增/删除项目，查看镜像仓库，给项目添加成员、查看操作日志、复制项目等
• 日志：仓库各个镜像create、push、pull等操作日志
• 系统管理
  • 用户管理：新增/删除用户、设置管理员等
  • 仓库管理：新增/修改目标等
  • 复制管理：新增/删除从库目标、新建/删除/启停复制规则等
  • 配置管理：认证模式、复制、邮箱设置、系统设置等

注意：非系统管理员用户登录，只能看到有权限的项目和日志，其他模块不可见。

到此，Harbor就安装完成，现在我们可以使用docker login进行登录，这里我切换到另外一台服务器(Centos)去进行远程登录

{18-10-13 19:16}localhost:~ root# docker login 192.168.71.106
Username: admin
Password: 
Error response from daemon: Get https://192.168.71.106/v1/users/: dial tcp 192.168.71.106:443: getsockopt: connection refused

上面请求的是https，因为docker1.3.2版本开始默认docker registry使用的是https，我们设置Harbor默认http方式。要解决上面的问题，就需要配置docker的damone.json配置：

#里面可以写多个IP地址，IP地址为我们搭建Harbor的仓库地址，如果有端口，可以加在后面
{18-10-13 19:12}localhost:~ root# echo '{ "insecure-registries":["192.168.71.106"] }' >  /etc/docker/daemon.json 
{18-10-13 19:15}localhost:~ root# systemctl daemon-reload               
{18-10-13 19:15}localhost:~ root# systemctl restart docker.service

#上面操作完后，再次进行登录，成功
{18-10-13 19:20}localhost:~ root# docker login 192.168.71.106
Username: admin
Password: 
Login Succeeded

提交本地镜像到Harbor仓库

# 首先从docker hub下载nginx镜像
{18-10-13 19:28}localhost:~ root# docker pull nginx

# 给镜像打tag
{18-10-13 19:32}localhost:~ root# docker tag docker.io/nginx 192.168.71.106/library/nginx:latest
{18-10-13 19:33}localhost:~ root# docker images

# 提交镜像
{18-10-13 19:35}localhost:~ root# docker push 192.168.71.106/library/nginx 
The push refers to a repository [192.168.71.106/library/nginx]

上面提交成功后，如果是公开项目，那么就可以直接使用下面的命令直接拉取下来：

{18-10-13 19:52}localhost:~ root# docker pull 192.168.71.106/library/nginx

如果是私有项目不是该项目的成员就不能进行拉取，会提示不存在或没有权限：

{18-10-13 19:52}localhost:~ root# docker pull 192.168.71.106/library/nginx  #没有登录的用户或该用户不是该项目的成员，就拉取不了     
Using default tag: latest
Trying to pull repository 192.168.71.106/library/nginx ... 
repository 192.168.71.106/library/nginx not found: does not exist or no pull access

如果要拉取就需要设置项目对应的成员，那么设置了的成员就可以进行拉取了。

好了！整个Harbor的搭建之旅就暂告一段落。夜深人静可以休息了，后续还有什么新的知识再做补充。
