1、前言
谈及docker，避免不了需要熟练的记住好多命令及其用法，对于熟悉shell、技术开发人员而言，还是可以接受的，熟练之后，命令行毕竟是很方便的，便于操作及脚本化。但对于命令行过敏、非技术人员，进行docker部署、管理是比较头疼的，学习成本是很高的。
倘若有一款可视化的管理平台能够使用，那便是极好的。在技术的世界里，没有你做不到，只有你想不到，shipyard就有这样功能的，是一个docker可视化管理工具。此外还有其他可视化的docker管理工具供大家使用参考。
友情提示：
对于docker初学者，不推荐使用docker可视化工具，还是先多熟悉熟悉命令行吧，这样便于理解docker。
2、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。
通过Web用户界面，你可以浏览相关信息，比如你的容器在使用多少处理器和内存资源、在运行哪些容器，哪些镜像，还可以检查所有集群上的事件日志等。
其特性主要包括：
1）支持节点动态集群，可扩展节点的规模（swarm、etcd方案）
2）支持镜像管理、容器管理、节点管理等功能
3）可视化的容器管理和监控管理
4）在线连接容器console终端
容器管理：
展示整个docker环境的容器列表，容器状态，容器属性、容器创建等。
具体容器详情：
可以对容器进行相关的操作，如容器的基本信息、启停、删除、状态监控(CPU、内存、网络情况)、日志查看、进入容器终端(docker exec)。
镜像管理：
展示所有镜像列表，镜像基本信息、镜像删除、下载等。
此外，还有节点管理、仓库管理、用户管理等等，在此不一一罗列，安装完之后，自己慢慢体验吧。
