CentOS部署Harbor镜像仓库

CentOS部署Harbor镜像仓库

 

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;

  1. 官方网站:https://goharbor.io/
  2. 官方开源:https://github.com/goharbor/harbor

环境信息

今天要部署的Harbor版本是1.9.0,本次部署用的机器信息如下:

  1. 操作系统:CentOS Linux release 7.7.1908
  2. Docker:19.03.2
  3. 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;

  1. 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/harbor/releases ,如下图红框所示,我选择了最新版的1.9.0:
    在这里插入图片描述
  2. 将离线安装包harbor-offline-installer-v1.9.0.tgz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harbor的文件夹,进入该文件夹;

  1. 修改配置文件harbor.yml,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;
  2. 开始安装,在install.sh文件所在目录执行命令./install.sh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.

  1. 此时应该有九个容器正常运行:
[root@vostro ~]# docker ps

  1. 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admin,密码是前面设置的harbor_admin_password的值(默认是Harbor12345):

  2. 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;

  1. 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;
  2. 编辑A电脑的/etc/docker/daemon.json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"]
}
  1. 重启使配置生效:
systemctl daemon-reload  && systemctl restart docker

再次提醒: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;

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;

  1. 登录A电脑,选个本地镜像用来测试,我这里有个名为jenkinsci/blueocean:1.19.0的本地镜像,ID为11e2757c8bc1
root@hedy:~# docker images
REPOSITORY                          TAG                 IMAGE ID            CREATED             SIZE
jenkinsci/blueocean                 1.19.0              11e2757c8bc1        7 days ago          553MB
  1. 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;
3. 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
  1. 执行命令docker push 192.168.50.167/library/jenkinsci/blueocean:1.19.0
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]

  1. 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。
