网站建设代理平台公司做网站一般多少钱
简述：
Docker 官方镜像仓库是用于管理公共镜像的地方，大家可以在上面找到想要的镜像，也可以把自己的镜像推送上去。但是有时候服务器无法访问互联网，或者不希望将自己的镜像放到互联网上，那么就需要用到 Docker Registry 私有仓库，它可以用来存储和管理自己的镜像。最近公司将项目全部打包成镜像有部署私有仓库服务的需求，经过几轮商讨，最终选择 Docker Harbor，Docker Harbor 有可视化的 Web 管理界面可以方便管理Docker 镜像操作也很方便简单，又提供了多个项目的镜像权限管理控制功能等。
Harbor 架构构成
- 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。

Harbor 日常操作管理
点击“+项目”时按规范填写项目名称。项目级别：私有即不勾选(勾选后会变为"公开")。如果设置为公共仓库，则所有人对此项目下的镜像拥有读权限，命令行中不需要执行"Docker login"即可下载镜像，镜像操作与Docker hub 一致。
创建用户
设置权限
首先退出当前用户，然后使用上述创建的账户 登录。
退出

管理 Harbor
可以使用 docker-compose来管理Harbor。一些有用的命令如下所示（必须在与docker-compose.yml 相同的目录中运行）。
停止/启动/重启 Harbor
[root@master harbor]# docker-compose stop | start | restart
