docker-machine 使用（二）

docker-machine 二

修改创建虚拟机的位置

环境变量添加 MACHINE_STORAGE_PATH 的值为新的路径

删除 c:/user/用户名/.docker 目录

找到 Docker Toolbox 的安装目录，比如我的是 D:\softSetUp\Docker Toolbox，这个目录下面有个 start.sh,用 bash 执行这个命令就可以创建 docker 虚拟机，此时虚拟机就是创建在我们设置的目录

但是这个脚本我们只能创建名字为 default 的虚拟机，很多东西是不能定义的，我这里改了一下脚本可以自定义几个参数：

#!/bin/bash

trap '[ "$?" -eq 0 ] || read -p "Looks like something went wrong in step ´$STEP´... Press any key to continue..."' EXIT

#Quick Hack: used to convert e.g. "C:\Program Files\Docker Toolbox" to "/c/Program Files/Docker Toolbox"
win_to_unix_path(){
    wd="$(pwd)"
    cd "$1"
        the_path="$(pwd)"
    cd "$wd"
    echo $the_path
}

    case $opt in
        i)

        VM=${OPTARG}

        d)

        DISK_SIZE=${OPTARG}
        ;;
        ?)
        echo "未知参数"
        exit 1;;
    esac

参数说明：

-i boot2docker.iso 的路径
-n 虚拟机的名字
-d 虚拟机的硬盘大小
已经加入了阿里镜像加速

用法：

./start.sh -i boot2docker -n mydocker -d 30000
