Docker 是最近相當熱門的一個名詞，它是一個基于 Linux Container 的輕量化的虛擬技術，而微軟也相當積極與 Docker 合作，在 Azure 上支持這個火熱的技術，并且提供簡單的方式來建立 Docker Host，本文將會介紹如何在 Azure 上使用 Docker運行DockerMono鏡像。
Docker 簡介
Docker 是一個開源的項目，主要的特點是能將應用程序包裝在一個 LXC (Linux Container) 容器中，當這些應用被包裝進容器后，部署、遷移都變得更為簡單。與傳統(tǒng)的虛擬化技術相比，虛擬機需要安裝操作系統(tǒng)才能執(zhí)行應用程序，而 Container 則不需要安裝操作系統(tǒng)就能運行應用程序。Container 技術是一種在 操作系統(tǒng)內(nèi)的 Kernel 層所打造虛擬運行環(huán)境，所以 Container 彼此之間共享了 Host OS 的 Kernel，但通過namespace 區(qū)分來達到隔離每個容器的目的。
本文主要著重介紹Azure 對于 Docker 所提供的支持。
在 Azure 上建立 Docker Host
Docker 可以運行在 Linux 操作系統(tǒng)之下，所以如果要在 Azure 上使用 Docker，您也可以自行建立一個Linux VM，并在上面安裝 并運行Docker Deamon 。而微軟在正式宣布與 Docker 密切合作后，推出了對 Docker 的直接支持，CentOS 7 中 Docker 的安裝
Docker 軟件包已經(jīng)包括在默認的 CentOS-Extras 軟件源里。因此想要安裝 docker，只需要運行下面的 yum 命令：
- [root@Mono ~]# yum install docker
啟動 Docker 服務
- [root@ Mono ~]# systemctl start docker.service
- [root@ Mono ~]# systemctl enable docker.service
下載官方的 CentOS 鏡像到本地
- [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
確認 CentOS 鏡像已經(jīng)被獲取：
- [root@Mono ~]# docker images centos
- REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
- centos latest 34943839435d 13 days ago 224 MB
運行一個 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

- bash_completion.d hosts.allow pki shells

- centos-release inputrc prelink.conf.d sysconfig

- cron.daily issue profile system-release

- csh.cshrc krb5.conf protocols systemd
- csh.login ld.so.conf rc.d terminfo

- 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
我們可以看到，CentOS 容器已經(jīng)被啟動，并且我們得到了 bash 提示符。在 docker 命令中我們使用了 "-i 捕獲標準輸入輸出"和 "-t 分配一個終端或控制臺"選項。若要斷開與容器的連接，輸入 exit。
- [root@5d841f64f6f0 /]# exit
Exit
#p#
我們還可以搜索基于 mono的容器。 發(fā)現(xiàn)已經(jīng)有非常多的mono容器，我們開始玩docker mono。
