Docker 是最近相当热门的一个名词，它是一个基于 Linux Container 的轻量化的虚拟技术，而微软也相当积极与 Docker 合作，在 Azure 上支持这个火热的技术，并且提供简单的方式来建立 Docker Host，本文将会介绍如何在 Azure 上使用 Docker运行DockerMono镜像。
Docker 简介
Docker 是一个开源的项目，主要的特点是能将应用程序包装在一个 LXC (Linux Container) 容器中，当这些应用被包装进容器后，部署、迁移都变得更为简单。与传统的虚拟化技术相比，虚拟机需要安装操作系统才能执行应用程序，而 Container 则不需要安装操作系统就能运行应用程序。Container 技术是一种在 操作系统内的 Kernel 层所打造虚拟运行环境，所以 Container 彼此之间共享了 Host OS 的 Kernel，但通过namespace 区分来达到隔离每个容器的目的。
本文主要着重介绍Azure 对于 Docker 所提供的支持。
在 Azure 上建立 Docker Host
Docker 可以运行在 Linux 操作系统之下，所以如果要在 Azure 上使用 Docker，您也可以自行建立一个Linux VM，并在上面安装 并运行Docker Deamon 。而微软在正式宣布与 Docker 密切合作后，推出了对 Docker 的直接支持，CentOS 7 中 Docker 的安装
Docker 软件包已经包括在默认的 CentOS-Extras 软件源里。因此想要安装 docker，只需要运行下面的 yum 命令：
- [root@Mono ~]# yum install docker
启动 Docker 服务
- [root@ Mono ~]# systemctl start docker.service
- [root@ Mono ~]# systemctl enable docker.service
下载官方的 CentOS 镜像到本地
- [root@Mono ~]# docker pull centos
- centos:latest: The image you are pulling has been verified
- 511136ea3c5a: Pull complete
- 5b12ef8fd570: Pull complete
- 34943839435d: Pull complete
- Status: Downloaded newer image for centos:latest
确认 CentOS 镜像已经被获取：
- [root@Mono ~]# docker images centos
- REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
- centos latest 34943839435d 13 days ago 224 MB
运行一个 Docker 容器：
- [root@Mono ~]# docker run -i -t centos /bin/bash
- [root@5d841f64f6f0 /]# ls /etc
- BUILDTIME group nsswitch.conf rpm
- DIR_COLORS group- openldap sasl2
- DIR_COLORS.256color gshadow opt securetty
- DIR_COLORS.lightbgcolor gshadow- os-release security
- GREP_COLORS gss pam.d selinux
- X11 host.conf passwd services
- aliases hostname passwd- shadow
- alternatives hosts pkcs11 shadow-
- bash_completion.d hosts.allow pki shells
- bashrc hosts.deny pm skel
- binfmt.d init.d popt.d ssl
- centos-release inputrc prelink.conf.d sysconfig
- chkconfig.d iproute2 printcap sysctl.d
- cron.daily issue profile system-release
- cron.hourly issue.net profile.d system-release-cpe
- csh.cshrc krb5.conf protocols systemd
- csh.login ld.so.conf rc.d terminfo
- dbus-1 ld.so.conf.d rc0.d tmpfiles.d
- default libaudit.conf rc1.d udev
- dracut.conf.d libuser.conf rc2.d virc
- environment localtime rc3.d xdg
- exports login.defs rc4.d xinetd.d
- filesystems logrotate.d rc5.d yum
- fstab magic rc6.d yum.conf
- gcrypt modules-load.d redhat-release yum.repos.d
- gnupg motd resolv.conf
- groff mtab rpc
我们可以看到，CentOS 容器已经被启动，并且我们得到了 bash 提示符。在 docker 命令中我们使用了 "-i 捕获标准输入输出"和 "-t 分配一个终端或控制台"选项。若要断开与容器的连接，输入 exit。
- [root@5d841f64f6f0 /]# exit
Exit
#p#
我们还可以搜索基于 mono的容器。 发现已经有非常多的mono容器，我们开始玩docker mono。
- [root@Mono ~]# docker search mono
