docker仓库之harbor高可用 (三)

基于上一篇部署完成了企业级仓库harbor的部署，今天我们来聊聊什么是harbor的高可用

Harbor 支持基于策略的 Docker 镜像复制功能，这类似于 MySQL 的主从同步，
其可以实现不同的数据中心、不同的运行环境之间同步镜像，并提供友好的管理
界面，大大简化了实际运维中的镜像管理工作，已经有用很多互联网公司使用
harbor 搭建内网 docker 仓库的案例，并且还有实现了双向复制的案列，本文将
实现单向复制的部署：

1.准备机器
#我这边直接复用上一篇的10.0.0.110，再开一个虚机为10.0.0.111
10.0.0.110  harbor1
10.0.0.111  harbor2
2.更改主机名
#为了清晰看见，我这里做了主机名修改
root@ubuntu1804:~# hostnamectl set-hostname harbor1
root@ubuntu1804:~# hostnamectl set-hostname harbor2
root@harbor2:~# apt install lrzsz
3.安装docker
root@harbor2:~# bash docker-install.sh
4.解压缩和安装插件
root@harbor2:/usr/local/src# tar -xvf harbor-offline-installer-v1.7.6.tgz
#安装插件我这里就不多说了，在我的harbor安装有详细步骤说明
5.安装成功
[Step 4]: starting Harbor ...
Creating network "harbor_harbor" with the default driver
Creating harbor-log ... done
Creating harbor-adminserver ... done
Creating registryctl        ... done
Creating harbor-db          ... done
Creating registry           ... done
Creating redis              ... done
Creating harbor-core        ... done
Creating harbor-portal      ... done
Creating harbor-jobservice  ... done
Creating nginx              ... done

✔ ----Harbor has been installed and started successfully.----

6.验证从harbor登录

 

 7.创建一个linux项目

#和主harbor的项目名称保持一致

 

8.测试登录harbor2
root@harbor2:/usr/local/src/harbor# docker login 10.0.0.111
Username: admin
Password: 
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
root@harbor2:/usr/local/src/harbor# docker login 10.0.0.110
Username: admin
Password: 
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

9.点击复制管理，设置harbor的主同步策略， 主harbor和从harbor设置双向同步规则！！！

 

 

 

10.主harbor查看镜像同步状态

 

 

 

11.查看镜像是否以及被同步

 

 

12.测试可以上传和下载
#本次测试我重新开了一台机器

root@ubuntu1804:~# docker pull 10.0.0.110/linux/nginx:latest
latest: Pulling from linux/nginx
45b42c59be33: Pull complete 
8acc495f1d91: Pull complete

Status: Downloaded newer image for 10.0.0.110/linux/nginx:latest
10.0.0.110/linux/nginx:latest

13.现在我在客户机上传一个镜像上传到我的10.0.0.110的harbor上，查看是否会被备份在10.0.0.111的机器

root@ubuntu1804:~# docker tag mysql:latest 10.0.0.110/linux/mysql:latest
root@ubuntu1804:~# docker push 10.0.0.110/linux/mysql:latest 
The push refers to repository [10.0.0.110/linux/mysql]

14.查看mysql镜像是否被备份

 

 

 

结语：本次harbor的高可用到这里全部OK！！！
