1，简单介绍。
Harbor，是一个英文单词，意思是港湾，港湾是干什么的呢，就是停放货物的，而货物呢，是装在集装箱中的，说到集装箱，就不得不提到Docker容器，因为docker容器的技术正是借鉴了集装箱的原理。所以，Harbor正是一个用于存储Docker镜像的企业级Registry服务。
Harbor是Vmvare中国团队开发的开源registry仓库，相比docker官方拥有更丰富的权限权利和完善的架构设计，适用大规模docker集群部署提供仓库服务。
2，主要组件。
- Proxy：Harbor的registry, UI, token等服务，通过一个前置的反向代理统一接收浏览器、Docker客户端的请求，并将请求转发给后端不同的服务。
- Registry： 负责储存Docker镜像，并处理docker push/pull 命令。由于我们要对用户进行访问控制，即不同用户对Docker image有不同的读写权限，Registry会指向一个token服务，强制用户的每次docker pull/push请求都要携带一个合法的token, Registry会通过公钥对token 进行解密验证。
- Core services： 这是Harbor的核心功能，主要提供以下服务：
1，UI：提供图形化界面，帮助用户管理registry上的镜像（image）, 并对用户进行授权。
2，webhook：为了及时获取registry 上image状态变化的情况， 在Registry上配置webhook，把状态变化传递给UI模块。
3，token 服务：负责根据用户权限给每个docker push/pull命令签发token. Docker 客户端向Regiøstry服务发起的请求,如果不包含token，会被重定向到这里，获得token后再重新向Registry进行请求。

3，token 服务：负责根据用户权限给每个docker push/pull命令签发token. Docker 客户端向Regiøstry服务发起的请求,如果不包含token，会被重定向到这里，获得token后再重新向Registry进行请求。
- Database：为core services提供数据库服务，负责储存用户权限、审计日志、Docker image分组信息等数据。
- Log collector：为了帮助监控Harbor运行，负责收集其他组件的log，供日后进行分析。
有架构图如下：
- CentOS：7.3
- docker-ce：17.12.1
- docker-compose：version-1.18.0
- harbor-offline：v1.5.1
3，安装。
1，安装docker。
wget http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo && mv docker-ce.repo /etc/yum.repos.d yum -y install docker-ce-17.12.1.ce-1.el7.centos
启动服务。
systemctl enable docker systemctl start docker systemctl status docker
2，安装docker-compose。
源码地址：https://github.com/docker/compose/releases
下载指定版本。
curl -L https://github.com/docker/compose/releases/download/1.18.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
添加执行权限。
chmod +x /usr/local/bin/docker-compose
验证一下。
$docker-compose --version 输出： docker-compose version 1.18.0, build 8dd22a9
3，安装harbor。
源码地址：https://github.com/goharbor/harbor/releases
项目分有在线版，以及离线版，这里介绍离线版的安装。
下载安装包。
wget https://storage.googleapis.com/harbor-releases/release-1.5.0/harbor-offline-installer-v1.5.1.tgz
或许用迅雷下载，速度更佳。
解压安装包。
$tar xf harbor-offline-installer-v1.5.1.tgz $ls harbor common docker-compose.clair.yml docker-compose.notary.yml docker-compose.yml ha harbor.cfg harbor.v1.5.1.tar.gz install.sh LICENSE NOTICE prepare
更改配置。
$vim harbor.cfg 将hostname更改为本机ip即可。 hostname = 192.168.111.5
其他的配置保持默认即可，还有一些常用配置，如果需要，可以自行按需修改。
执行安装。

看到这些输出，说明安装已经完成。
查看一下服务：

访问私服仓库。
192.168.111.5
默认用户名/密码：admin/Harbor12345
登陆之后可以修改一下密码。
4，客户端验证。
在另外一台主机上安装docker服务，验证私服可用性。
1，安装docker。
wget http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo && mv docker-ce.repo /etc/yum.repos.d yum -y install docker-ce-17.12.1.ce-1.el7.centos
启动服务。
systemctl enable docker systemctl start docker systemctl status docker
2，配置私服连接。
cat > /etc/docker/daemon.json << EOF
{ "insecure-registries":["192.168.111.5"] }
EOF
重启docker。
systemctl daemon-reload systemctl restart docker
登陆私服，如果登陆失败，可能是两台主机时间不同步。
$docker login -u admin -p Harbor12345 192.168.111.5 WARNING! Using --password via the CLI is insecure. Use --password-stdin. Login Succeeded
3，验证拉取镜像。
先本地pull一个镜像。
$docker pull busybox Using default tag: latest latest: Pulling from library/busybox 90e01955edcd: Pull complete Digest: sha256:2a03a6059f21e150ae84b0973863609494aad70f0a80eaeb64bddd8d92465812 Status: Downloaded newer image for busybox:latest $docker images REPOSITORY TAG IMAGE ID CREATED SIZE busybox latest 59788edf1f3e 2 months ago 1.15MB
更改一下tag，测试一下push。
$docker tag busybox 192.168.111.5/library/busybox:1 $docker push 192.168.111.5/library/busybox:1 The push refers to repository [192.168.111.5/library/busybox] 8a788232037e: Pushed 1: digest: sha256:915f390a8912e16d4beb8689720a17348f3f6d1a7b659697df850ab625ea29d5 size: 527
可以在私服当中看到这个镜像：
本地删除镜像，然后测试一下pull。
查看镜像。 $docker images REPOSITORY TAG IMAGE ID CREATED SIZE 192.168.111.5/library/busybox 1 59788edf1f3e 2 months ago 1.15MB busybox latest 59788edf1f3e 2 months ago 1.15MB 删除本地镜像。 $docker rmi -f 59788edf1f3e 59788edf1f3e 从本地私服pull镜像。 $docker pull 192.168.111.5/library/busybox:1 1: Pulling from library/busybox 90e01955edcd: Pull complete Digest: sha256:915f390a8912e16d4beb8689720a17348f3f6d1a7b659697df850ab625ea29d5 Status: Downloaded newer image for 192.168.111.5/library/busybox:1 再次查看镜像。 $docker images REPOSITORY TAG IMAGE ID CREATED SIZE 192.168.111.5/library/busybox 1 59788edf1f3e 2 months ago 1.15MB
