一、前言

先回顧下上一節建立docker-machine的過程，預設情況下docker toolbox中的docker-machine使用virtual box建立虛擬機器，KI首次啟動時建立虛擬機器的過程，大致相當於下面這條命令：

docker-machine create --driver virtualbox default

輸出如下：

Running pre-create checks...
Creating machine...
(default) Copying /Users/yjmyzz/.docker/machine/cache/boot2docker.iso to /Users/yjmyzz/.docker/machine/machines/default2/boot2docker.iso...
(default) Creating VirtualBox VM...
(default) Creating SSH key...
(default) Starting the VM...
(default) Waiting for an IP...
Waiting for machine to be running, this may take a few minutes...
Machine is running, waiting for SSH to be available...
Detecting operating system of created instance...
Detecting the provisioner...
Provisioning with boot2docker...
Copying certs to the local machine directory...
Copying certs to the remote machine...
Setting Docker configuration on the remote daemon...
Checking connection to Docker...
Docker is up and running!
To see how to connect Docker to this machine, run: docker-machine env default

其大致過程為從網上下載boot2docker.iso這個檔案，然後利用它建立VirtualBox VM，然後生成SSH key(方便免密碼登入到虛擬機器)、分配IP之類，建立完以後，可以用:

docker-machine env default

檢視虛擬機器default的狀態，如果要刪除該虛擬機器，直接

rm -rf ~/.docker/machine/machines/default

現在才開始本文的正題：

二、使用vmware做為docker machine

對於已經在mac上安裝了vmwarefusion的同學來講，為了使用docker強制安裝一個virtualbox有點多餘，其實docker支援vmwarefusion,只要把driver改一下就行了，命令如下：

docker-machine create --driver vmwarefusion default

建立完成後，用docker-machine ls列出所有虛擬機器

可以看到型別確實為vmwarefusion，然後可以

docker-machine ssh default

連線到虛擬機器的終端下，順便ping下外網地址，檢查下虛擬機器裡是否能上網(這個很重要，因為後面下載映象需要聯網)

如果有條件翻*^牆的同學，可以執行

docker pull kitematic/hello-world-nginx 

直接從docker hub拉一個只有幾M的映象檔案試試

三、設定國內映象加速pull

docker hub官網太慢了，還好國內有一家公司daocloud提供了加速服務，設定步驟：

過程略，註冊成功後，進入控制檯

3.2 點選控制檯上的加速器

拉到中間部分，有一個『主機監控程式』的文字連結，見下圖：

然後選擇主機型別，我用的是mac，所以選擇mac主機：

如果已經安裝好了docker toolbox最新版，直接點選【安裝好了】

然後會出現二條命令，複製貼上執行即可：

注：如果按它的提示，最後出現latest: Pulling from daocloud/daomonit not found之類的錯誤，可以嘗試

docker logout daocloud.io

然後重試，安裝成功後，執行

dao pull ubuntu

就可以感受下速度了

如果好奇dao這個命令是什麼鬼？可以

which dao

查詢下位置，正常情況下應該在/usr/local/bin/dao下，可以cat看下該檔案的內容：

#!/bin/sh
