关于Harbor
Harbor是用于存储和分发Docker镜像的镜像仓库服务,相比Docker Registry,Harbor在安全、标识、管理等方面做了增强,更适合企业使用;
环境信息
今天要部署的Harbor版本是<font color="blue">1.9.0</font>,本次部署用的机器信息如下:
- 操作系统:CentOS Linux release 7.7.1908
- Docker:19.03.2
- docker-compose:1.23.2
部署Harbor
Harbor官方提供了在线和离线两种安装方式,考虑到企业服务器有可能无法访问外网,因此选择离线安装更加实用;
- 打开Harbor的GitHub仓库的release页面下载离线安装包,地址是:https://github.com/goharbor/h... ,如下图红框所示,我选择了最新版的1.9.0:
- 将离线安装包<font color="blue">harbor-offline-installer-v1.9.0.tgz</font>下载到电脑上,执行以下命令解压:
tar -zxvf harbor-offline-installer-v1.9.0.tgz
解压的结果是个名为<font color="blue">harbor</font>的文件夹,进入该文件夹;
- 修改配置文件<font color="blue">harbor.yml</font>,主要是修改以下两个配置:
a. hostname:填写本机的IP地址或者hostname,如果已经和域名绑定了也可以填域名;
b. harbor_admin_password:管理员初始密码;
更多配置例如https、存储等,请参考官方文档按需设置; - 开始安装,在install.sh文件所在目录执行命令<font color="blue">./install.sh</font>即可安装Harbor,部署成功的控制台信息如下:
Creating network "harbor_harbor" with the default driver
Creating harbor-log ... done
Creating registryctl ... done
Creating registry ... done
Creating harbor-db ... done
Creating redis ... done
Creating harbor-portal ... done
Creating harbor-core ... done
Creating nginx ... done
Creating harbor-jobservice ... done
✔ ----Harbor has been installed and started successfully.----
Now you should be able to visit the admin portal at http://192.168.50.167.

- 此时应该有九个容器正常运行:

- 由于Harbor的web服务使用了宿主机的80端口,所以在浏览器直接输入宿主机的IP地址即可访问Harbor的web管理页面,账号是<font color="blue">admin</font>,密码是前面设置的<font color="blue">harbor_admin_password</font>的值(默认是Harbor12345):
- 登录成功后发现空空如也,也是,目前还没啥东西:
允许http连接
接下来我们要验证Harbor服务是否可用,验证方式是从另一台Linux电脑(下面称之为A电脑)远程推送镜像到Harbor机器;
Harbor默认是不允许http连接的,这里可以修改设置来支持http连接,以便后续的验证操作;
- 如果要从A电脑连接Harbor服务器,那么要对A电脑做设置,这里A电脑是Linux操作系统;
- 编辑A电脑的<font color="blue">/etc/docker/daemon.json</font>文件(如果不存在就新建),增加以下内容,192.168.50.167是Harbor服务器的IP地址:
{
"insecure-registries":["192.168.50.167"]
}
- 重启使配置生效:
systemctl daemon-reload && systemctl restart docker
再次提醒:<font color="red">这里修改是远程连接Harbor服务的机器的配置,而不是Harbor服务器的配置;</font>
推送镜像到Harbor
接下来验证Harbor的服务,在A电脑上尝试将本机的镜像推送到Harbor;
- 登录A电脑,选个本地镜像用来测试,我这里有个名为<font color="blue">jenkinsci/blueocean:1.19.0</font>的本地镜像,ID为<font color="blue">11e2757c8bc1</font>:
root@hedy:~# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
jenkinsci/blueocean 1.19.0 11e2757c8bc1 7 days ago 553MB
- 执行以下命令,将选定的本地镜像修改名称和TAG:
docker tag 11e2757c8bc1 192.168.50.167/library/jenkinsci/blueocean:1.19.0
上述命令中,192.168.50.167是安装harbor的时候,harbor.yml文件中配置的hostname的值,library是harbor默认的项目名称;
- 执行以下命令即可从A电脑登录Harbor:
docker login 192.168.50.167 -u admin -p Harbor12345
- 执行命令<font color="blue">docker push 192.168.50.167/library/jenkinsci/blueocean:1.19.0</font>
root@hedy:~# docker push 192.168.50.167/library/jenkinsci/blueocean:1.19.0
The push refers to repository [192.168.50.167/library/jenkinsci/blueocean]

- 上传完毕,登录Harbor网页,可以看到新上传的镜像:
至此,实战完毕,在您搭建Harbor服务的时候希望本文能给您一些参考。
