Build, Ship and Run Any App, AnywhereDocker - An open platform for distributed applications for developers and sysadmins.

1. BuildDevelop an app using Docker containers with any language and any toolchain.2. ShipShip the "Dockerized" app and dependencies anywhere - to QA, teammates, or the cloud - without breaking anything.3. RunScale to 1000s of nodes, move between data centers and clouds, update with zero downtime and more.

1. the application: which may be only 10s of MB2. the necessary binaries and libraries3. an entire guest operating system - which may weigh 10s of GB 

1. the application 2. its dependencies(Bins/Libs)

1. 一个Container通常包含应用及应用依赖项，Container用来隔离进程，这些进程主要运行在主机操作系统上的隔离区和用户空间。这个是明显不同于传统的VMs2. 传统的硬件虚拟化(例如VMWare、KVM、Xen、EC2)旨在创造一个完整虚拟机。每个虚拟化应用不仅包含应用的二进制文件，还需运行该应用程序所需的库、一个完整的Guest操作系统 3. 由于所有的容器共享同一个操作系统(以及二进制文件和库)，所以，他们明显要比VM小的多，这样，就完全可以在一个物理主机上托管100个VMs(一般VM数量会受到严格限制)。此外，因为它们使用主机操作系统，重启一个VM并不意味着要重启操作系统，因此，容器更加轻便、高效 4. Docker中的容器效率会更高。因为一个传统的VM、应用、每个应用副本以及每个应用微小的变更都需要重新创建一个完整的VM  一个新的应用在主机上仅仅包含应用及其二进制文件/库，这样就无需创建一个新的客户机操作系统。 5. 如果想在主机上运行该应用的几个副本，你甚至无需复制共享的二进制文件，即使你对应用进行了变更，你也无需拷贝变更内容

1. 是写应用的人不用管操作系统的事了(我只会写JAVA，不懂Linux，没关系，你把JAVA相关的配置搞好就好了)，因为应用都在container里面2. container既可以部署在笔记本的操作系统上，也可以部署到云环境，只要操作系统一样，其它区别都没关系。并且不需要安装，解压等等(这个类似于虚拟机，但是虚拟机要考虑虚拟机容器的不同，而对于

Spotify: Continuous DeliverySpotify streams music to more than 40 million users in 57 countries around the world.4. Baidu: Platform-as-a-Service (PaaS)Baidu, Inc. is the number one Chinese-language Internet search provider that has a broad portfolio of products including social-networking products, music products, mobile related products and other products and services.5. New Relic: Distributed Applications CompositionNew Relic is a Software Analytics company that makes sense of billions of metrics across millions of apps.6. Rackspace: Continuous IntegrationRackspace‘s email service (MailGun) that allows you to send, receive and track emails effortlessly. Mailgun has made significant investments in building a Docker-centric continuous integration system for this service where high-availability is a requirement.7. Yandex: Platform-as-a-Service (PaaS)Yandex is an European Internet company and the largest search provider in Russia. Yandex’s Platform-as-a-Service (PaaS) is using Docker for infrastructure virtualization and application isolation.8. Cambridge: Continuous DeliveryCambridge Healthcare provides online access to health records and analytics for both patients and clinicians. They replaced several AWS AMIs with a single bare metal host running Docker to speed up their Jenkins-based continuous delivery pipeline.9. eBay: Easy Application DeploymenteBay Now is eBay‘s local, same day delivery service. In this use case, Senior Architect Ted Dziuba discusses his use of Docker in a continuous integration process. He uses Docker to implement an efficient, automated path from the developer‘s laptop through test and QA.

1. 作为守护进程，在Linux主机上管理LXC容器    1) 使用namespaces来做权限的控制和隔离    2) 使用cgroups来进行资源的配置    3) 通过aufs来提高文件系统的资源利用率    aufs是UnionFS的一种，它可以把对文件系统的改动当成一次commit一层层的叠加。这样的话多个容器之间就可以共享他们的文件系统层次。这样的话极大的节省了对存储的需求，并且也能加速容器的启动2. 作为一个CLI，与守护进程的REST API进行对话(docker run ...)3. 作为仓库的客户端，分享你所构建的内容(docker pull, docker commit)

1. 安装、升级内核//Docker的运行需要Linux内核提供相应的支持sudo apt-get updatesudo apt-get install linux-image-generic-lts-raring linux-headers-generic-lts-raringsudo reboot2. 第一次添加Docker的repository到你的本地秘钥库sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9sudo apt-get updatesudo apt-get install lxc-docker//期间会遇到一个警告，说这个包不可靠，你只需要回复yes然后继续安装就可以了3. 官方也提供了一个简单脚本帮助你安装，你可以用curl来获取这个脚本然后执行安装curl -s https://get.docker.io/ubuntu/ | sudo sh4. 下载安装ubuntu的镜像封装到一个沙箱中sudo docker run -i -t ubuntu /bin/bash

1. 确认是否安装了AUFSsudo apt-get updatesudo apt-get install linux-image-extra-`uname -r`2. 之后的步骤同ubntu 12.04 (64 bit)

1. 所有的实例你都需要在你的机器中运行docker进程，后台运行docker进程，简单演示sudo docker -d &2. 现在你可以运行Docker客户端，默认情况下所有的命令都会经过一个受保护的Unix socket转发给docker进程,所以我们必须运行root或者通过sudo授权sudo docker help3. 下载ubuntu base镜像# Download an ubuntu imagesudo docker pull ubuntu4. 执行一个进程CONTAINER_ID=$(sudo docker run -d ubuntu /bin/sh -c "while true; do echo hello world; sleep 1; done")sudo docker logs $CONTAINER_ID5. 查看日志文件来确认它是否正常工作sudo docker attach -sig-proxy=false $CONTAINER_ID6. 连接到容器实时查看结果sudo docker ps7. 查看正在运行的进程sudo docker stop $CONTAINER_ID8. 当我们不需要时停止容器sudo docker ps
