Docker图形界面管理
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

Status: Downloaded newer image for docker.io/abh1nav/dockerui:latest2）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

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：
| 镜像名称 | 运行服务 | 描述 |
| rethinkdb | shipyard数据库 | 一个NoSQL数据库，用于存储shipyard系统的数据，比如账号、节点、容器等信息 |
| microbox/etcd | 服务注册、发现系统 | K/V存储系统，用于Swarm节点实现服务注册、发现。也支持consul、zookeeper。 |
| shipyard/docker-proxy | docker API代理 | 连接本地/var/run/docker.sock代理，用于让Swarm Agent连接API管理。 |
| swarm | swarm集群 | 官方管理Docker集群工具，使得多个engine为一个整体管理，对外提供Swarm manager API，用户就像操作单台engine一样。 |
| shipyard/shipyard | shipyard前端 | 容器web管理系统，内部连接Swarm Manager管理容器和RethinkDB存储数据。 |
Shipyard分为自动部署和手动部署，相关文档参照：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）
[root@centos7 ~]# docker run -itd --restart=always --name shipyard-rethinkdb rethinkdb
