之前都是使用命令行进行Docker的管理，这里简单介绍一下Docker的图形界面管理。之所以说简单介绍，是因为在生产环境都是集群，很少使用图形界面管理单台Docker主机，所以就演示记录一下，在个人测试时还是可以用到的。

一、使用Docker UI进行Docker管理

1）首先，下载Docker UI镜像

[root@centos7 ~]# docker pull abh1nav/dockerui:latest
    Trying to pull repository docker.io/abh1nav/dockerui ... 
    latest: Pulling from docker.io/abh1nav/dockerui
    a3ed95caeb02: Pull complete 
    5d3df020ecd3: Pull complete 
    bebf5a3b4dfb: Pull complete 
    e4452c0fe72b: Pull complete 
    6167d9726b07: Pull complete 
    53ebae19a314: Pull complete 
    Digest: sha256:a9c6c5393f561a0f42f41cfa80572b666e745d9b419569c42bac1e5cf9ceda32
    Status: Downloaded newer image for docker.io/abh1nav/dockerui:latest

2）创建Docker容器

[root@centos7 ~]# docker run -d -p 9000:9000 -v /var/run/docker.sock:/docker.sock --name dockerui abh1nav/dockerui:latest -e="/docker.sock" 
    5f32d12629381614c11fa9d0c742326319c3bdbd8142a61d28e3d61a091b9555
    [root@centos7 ~]# docker ps -l
    CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS              PORTS                    NAMES
    5f32d1262938        abh1nav/dockerui:latest   "./dockerui -e=/do..."   4 seconds ago       Up 3 seconds        0.0.0.0:9000->9000/tcp   dockerui

3）使用浏览器访问

二、使用Shipyard进行Docker管理

Shipyard也是基于Docker API实现的容器图形管理系统，支持container、image、engine、cluster等功能，可满足我们基本的容器部署需求。

Shipyard介绍：

shipyard是docker的web可视化界面管理工具，是建立在docker集群管理工具Citadel之上，可以管理镜像、容器、主机等资源的web图形化工具，包括core和extension两个版本，core即shipyard主要是把多个 Docker host上的 containers 统一管理（支持跨越多个host），extension即shipyard-extensions添加了应用路由和负载均衡、集中化日志、部署等。Shipyard是在Docker Swarm实现对容器、镜像、docker集群、仓库、节点进行管理的web系统。

Shipyard特性：

*  支持节点动态集群，可扩展节点的规模（swarm、etcd方案）
 *  支持镜像管理、容器管理、节点管理等功能
 *  可视化的容器管理和监控管理
 *  在线容console终端

Shipyard服务介绍：

   <td style="vertical-align:top;">镜像名称</td>

Shipyard分为自动部署和手动部署，相关文档参照：[http://shipyard-project.com/deploy/][http_shipyard-project.com_deploy] 。自动部署使用脚本自动完成，这里就做一下手动部署。

1）部署Datastore（也就是rethinkdb）
