DockerUI是一个开源的基于Docker API的web应用程序，提供等同Docker命令行的大部分功能，支持container管理，image管理。它最值得称道的是它华丽的设计和用来运行和管理docker的简洁的操作界面。
DockerUI优点：
1）支持container批量操作；
2）支持image管理（虽然比较薄弱）
DockerUI缺点：
1）不支持多主机。
2）不支持鉴权

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
通过脚本快速拉取镜像，启动容器：

1）RethinkDB
deploy首先启动的就是RethinkDB容器，shipyard采用RethinkDB作为数据库来保存用户等信息
2）Discovery
为了使用Swarm，我们需要一个外部的密钥值存储群容器，shipyard默认是采用了etcd。
3）shipyard_certs
证书管理容器，实现证书验证功能
4）Proxy
默认情况下，Docker引擎只监听Socket，我们可以重新配置引擎使用TLS或者使用一个代理容器，转发请求从TCP到Docker监听的UNIX Socket。
5）Swarm Manager
Swarm管理器
6）Swarm Agent
Swarm代理，运行在每个节点上。
7）Controller
shipyard控制器，Remote API的实现和web的实现。

我最喜欢的Google文档功能之一是它会在我工作时不断自动保存我的文档版本。这意味着即使我在进行关键更改之前忘记在某个点进行保存，也很有可能会自动创建一个保存点。至少，我可以将文档恢复到错误更改之前的状态，并从该点继续工作。对于在MacOS(或UNIX)上运行的Ruby编码器，是否有具有等效功能的工具？例如，一个工具会每隔几分钟自动将Gitcheckin我的本地存储库以获取我正在处理的文件。也许我有点偏执，但这点小保险可以让我在日常工作中安心。 最佳答案 虚拟机有些人可能讨厌我对此的回应，但我在编码时经常使用VIM，它具有自动保存功
是否可以让这段代码更紧凑？我在这里错过了什么吗？ifvaluemax_ratemax_rateelsevalueend 最佳答案 这里有一些完全不同的东西:[min_rate,value,max_rate].sort[1] 关于ruby-如何更优雅地记下这三种情况？，我们在StackOverflow上找到一个类似的问题： https://stackoverflow.com/questions/13309740/
