These are instructions to create a series of buttons within the Apple Home app that control PS4 power and open/close any app you want.
Install Node.js
Begin by installing Node.js if you haven't already. Their website has up-to-date versions and installation instructions for your OS.
For macOS I use Homebrew to install packages. If you're a developer (or an aspiring one), I highly recommend using it. Via homebrew, installing node is as simple as brew install node.

随着Docker的发展，Docker的生态圈也越来越成熟，GitHub上出现了很多与Docker相关的开源项目。近日，CenturyLink在其博客上总结了基于Docker的10个开发工具，主要集中在PaaS平台、集群管理、持续集成和Docker的管理工具等四个方面。InfoQ中文站在其基础上进行了整理，具体如下。
Flynn
Flynn是一个使用Go语言编写的开源PaaS平台，Flynn使用模块化的设计，任何一个模块都可以独立的进行修改、升级和替换。Flynn的目标是简化分布式环境中应用的部署和维护，通过使用git push命令，Flynn就可以将应用部署到Docker，从而省去了复杂的配置和操作。Flynn的架构大致分为两层，Layer 0是底层的资源层，提供分布式配置、任务调度、服务发现、主机隔离等基础功能；Layer 1基于Layer 0构建了一个用于集群中管理、部署、扩展服务的系统，主要包括管理API/客户端、Git接收器、数据存储、路由。Flynn目前仍在开发中，尚未发布稳定版，但已经获得了很多公司的资助，它被称为是下一代的开源PaaS平台。
Deis Deis也是一个支持共有云和私有云的开源PaaS系统，Deis基于Docker和CentOS构建了一个类Heroku的PaaS系统。Deis主要设计用来和不同的云提供商进行交互，目前支持 Rackspace、EC2、 DigitalOcean、Google Compute Engine、Bare-Metal。Deis使用out-of-the-box的方式支持Ruby、Python、Node.js、Java、Clojure、Scala、Play、PHP、Perl、Dart和Go语言，同样支持git push部署。Flynn和Deis都是两个基于Docker的云计算微PaaS技术，关于它们的区别，可以参考[这篇文章](http://www.centurylinklabs.com/flynn-vs-deis-the-tale-of-two-docker-micro-pa
