Docker企业级私有仓库——Harbor介绍和部署? docker容器应用及开发和运行离不开可靠的镜像管理,在前面的文章我们提到了我们在拉取镜像的时候使用的是docker官方提供的公共镜像仓库,但是无论从安全还是效率等其他方面考虑,我们还是需要部署在私有环境中的Registry。
? 而本文将介绍的是一款企业级docker镜像仓库Harbor的部署和使用,而且在之后的Kubernetes的集群中,也推荐使用Harbor仓库环境。
? Harbor是由VMware公司开源的企业级的Docker Registry管理项目,相比docker官方拥有更丰富的权限权利及完善的架构设计,适用于为大规模的docker集群部署提供仓库服务。其主要提供 了Dcoker Registry 管理界面UI,可基于角色访问控制、镜像复制、AD/LDAP 集成、日志审核等功能,并且完全支持中文。
先来看看harbor整体的架构图
其实Harbor自有组件是上图中的Core Service所提供的核心功能,Replication Job Services所提供的多个Harbor实例之间的镜像同步(复制)功能以及Log collector提供的监控以及日志分析功能
其中核心服务主要是三个方面:
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。
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。
Auth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Regi?stry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。
API: 提供Harbor 的RESTful API接口
? 而上图中其他的组件都是Harbor所依赖的外部组件,例如Nginx(做代理)、Registry v2(镜像仓库,官方负责存储镜像的位置)以及数据库等等
准备环境:一台部署好docker的虚拟机Centos7作为Harbor部署服务器,另一台也需要部署docker环境来作为客户端进行相关测试
具体规划:
服务端docker-harbor:192.168.0.135,Centos7操作系统,docker-ce(即docker环境)
、docker-compose、harbor
客户端(测试端):192.168.0.129;Centos7操作系统,docker-ce
下面开始进行部署配置
首先在harbor端安装配置docker-compose和harbor软件安装
可以通过curl命令下载(考验网速的时候到了~~):
下载docker-compose工具
curl -L https://github.com/docker/compose/releases/download/1.21.1/docker-compose-`uname -s-
uname -m` -o /usr/local/bin/docker-compose
下载harbor软件包
wget http://harbor.orientsoft.cn/harbor-1.2.2/harbor-offline-installer-v1.2.2.tgz
[root@localhost opt]# ls
containerd docker-compose docker.sh harbor-offline-installer-v1.2.2.tgz rh
[root@localhost opt]# chmod +x docker-compose
[root@localhost opt]# cp -p docker-compose /usr/local/bin/
[root@localhost opt]# ls
containerd docker-compose docker.sh harbor-offline-installer-v1.2.2.tgz rh
[root@localhost opt]# tar zxf harbor-offline-installer-v1.2.2.tgz -C /usr/local/

修改harbor配置文件harbor.cfg、使用给出的脚本启动harbor
[root@localhost harbor]# vim harbor.cfg
在该过程中,应该不难发现是会下载镜像和运行相关的容器的,我们可以查看一下
[root@localhost harbor]# docker images

可见下载了13个镜像并且运行了7个容器,其实这个时候harbor服务已经搭建完了,是不是简单到不可思议了呢?
既然上文说到harbor仓库不仅部署简单,而且可以通过web UI界面进行登录管理,那么我们如何登录呢?
这就还是需要回到harbor的配置文件中看了,我们使用cat harbor.cfg 命令查看一下结果如下图:
当然这个密码是初始密码,可以修改的
好了,我们现在使用浏览器输入IP地址进行登录验证
)
登录结果:
以上,Harbor的仓库就构建完成了,下面我们在web ui界面上进行一下操作,然后在命令行终端进行相关的测试验证。
我们创建一个私有项目myproject,用于测试上传和下载镜像
在Harbor服务器节点上登录仓库,先登进去才可以进行操作的哈!
[root@localhost harbor]# docker login -u admin -p Harbor12345 http://127.0.0.1/
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
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
现在测试拉取一个nginx镜像然后使用tag命令设置一个副本进行上传测试
[root@localhost harbor]# docker pull nginx
Using default tag: latest
latest: Pulling from library/nginx
54fec2fa59d0: Pull complete
4ede6f09aefe: Pull complete

...//省略多余内容
#上传命令执行
[root@localhost harbor]# docker push 127.0.0.1/myproject/nginx
The push refers to repository [127.0.0.1/myproject/nginx]

验证结果
点击myproject之后可以查看刚刚建立的项目中对应的镜像、成员、日志等信息
以上对于服务端的测试就到这里,有兴趣的朋友可以自己再继续尝试其他操作
下面测试通过客户端登录,及远程访问harbor,毕竟企业中需要大家共享该仓库,而且有对于不同的部门和不同人的身份都有着各自的权限(由领导或者老板决定的)
客户机当前环境
[root@localhost opt]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
[root@localhost opt]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
第一步先要指定私有仓库harbor服务器的位置,IP地址
修改docker服务配置文件、重载服务
~~~shell、
[root@localhost opt]# vim /usr/lib/systemd/system/docker.service
![](https://s4.51cto.com/images/blog/202004/28/15c4b1b71282c5a09b8e15a1fb9f1c2c.png?x-oss-process=image/watermark,size_16,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_100,g_se,x_10,y_10,shadow_90,type_ZmFuZ3poZW5naGVpdGk=)
~~~shell
[root@localhost opt]# systemctl daemon-reload
[root@localhost opt]# systemctl restart docker.service
此时我们进行登录
[root@localhost opt]# docker login -u admin -p Harbor12345 http://192.168.0.135
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
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
此时我们将刚刚创建的私有仓库的一个镜像拉取测试一下(结果对比如下)
[root@localhost opt]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
[root@localhost opt]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
[root@localhost opt]# docker pull 192.168.0.135/myproject/nginx:v1

[root@localhost opt]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
192.168.0.135/myproject/nginx v1 602e111c06b6 5 days ago 127MB
此时你也可以在web ui界面中查看对应的日志记录,必然有对应的操作记录(上文说过的“审计”特性)。
拉取测试完成了,接下来进行客户端上传测试
先退出登录,拉取测试镜像
[root@localhost opt]# docker logout http://192.168.0.135
Removing login credentials for 192.168.0.135
[root@localhost opt]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE

[root@localhost opt]# docker pull cirros
...//省略部分内容
tag标签后登录harbor仓库,进行上传测试
[root@localhost opt]# docker tag cirros:latest 192.168.0.135/myproject/cirros:v1
[root@localhost opt]# docker login -u admin -p Harbor12345 http://192.168.0.135
WARNING! Using --password via the CLI is insecure. Use --password-stdin.

[root@localhost opt]# docker push 192.168.0.135/myproject/cirros:v1

我们直接通过日志验证,顺便查看之前的操作是否留有记录
至此,部署安装,服务端以及客户端的上传下载测试都顺利完成了,最后补充一下有关harbor的管理与维护的操作
? 修改harbor.cfg配置文件需要先停止所有的harbor实例并且更新配置文件后,再运行prepare脚本进行重新的加载配置,之后进行重新创建和启动harbor实例
1、关闭所有容器(对应结果就是停止和移除的现象)
[root@localhost harbor]# docker-compose down -v
Stopping nginx ... done
Stopping harbor-jobservice ... done
Stopping harbor-ui ... done
Stopping registry ... done
Stopping harbor-db ... done
Stopping harbor-adminserver ... done
Stopping harbor-log ... done
Removing nginx ... done
Removing harbor-jobservice ... done
Removing harbor-ui ... done
Removing registry ... done
Removing harbor-db ... done
Removing harbor-adminserver ... done
Removing harbor-log ... done
Removing network harbor_harbor
[root@localhost harbor]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
[root@localhost harbor]# docker-compose ps
Name Command State Ports
------------------------------
2、根据需求更改配置文件之后执行prepare脚本
[root@localhost harbor]# vim harbor.cfg
[root@localhost harbor]# ls
common docker-compose.notary.yml harbor_1_1_0_template harbor.v1.2.2.tar.gz LICENSE prepare
docker-compose.clair.yml docker-compose.yml harbor.cfg install.sh NOTICE upgrade
[root@localhost harbor]# ./prepare
Clearing the configuration file: ./common/config/adminserver/env

Clearing the configuration file: ./common/config/nginx/nginx.conf
loaded secret from file: /data/secretkey
Generated configuration file: ./common/config/nginx/nginx.conf
Generated configuration file: ./common/config/adminserver/env
Generated configuration file: ./common/config/ui/env
Generated configuration file: ./common/config/registry/config.yml
Generated configuration file: ./common/config/db/env
Generated configuration file: ./common/config/jobservice/env
Generated configuration file: ./common/config/jobservice/app.conf
Generated configuration file: ./common/config/ui/app.conf
Generated certificate, key file: ./common/config/ui/private_key.pem, cert file: ./common/config/registry/root.crt
The configuration files are ready, please use docker-compose to start the service.
3、重启docker服务和容器服务
[root@localhost harbor]# systemctl restart docker
[root@localhost harbor]# docker-compose up -d
Creating network "harbor_harbor" with the default driver
Creating harbor-log ... done
Creating harbor-adminserver ... done
Creating registry ... done
Creating harbor-db ... done
Creating harbor-ui ... done
Creating nginx ... done
Creating harbor-jobservice ... done
结果:
[root@localhost harbor]# docker-compose ps
Name Command State Ports
-------------------------------------------------------------------------------------------------------------------------
harbor-adminserver /harbor/harbor_adminserver Up
harbor-db docker-entrypoint.sh mysqld Up 3306/tcp
harbor-jobservice /harbor/harbor_jobservice Up
harbor-log /bin/sh -c crond && rm -f ... Up 127.0.0.1:1514->514/tcp
harbor-ui /harbor/harbor_ui Up
nginx nginx -g daemon off; Up 0.0.0.0:443->443/tcp, 0.0.0.0:4443->4443/tcp,
0.0.0.0:80->80/tcp
registry /entrypoint.sh serve /etc/ ... Up 5000/tcp
主要是进行用户创建及测试
1、创建用户操作
2、为项目添加新用户
我们使用新用户在client端登录
以上就是简单的harbor仓库管理和维护介绍了。
谢谢阅读!
