先講解一下如何創建一個machine
1. 打開命令行
2. 使用 docker-machine ls 命令，默認情況下如下
$ docker-machine ls
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
3. 創建一個machine
- 如果你使用mac，不支持Hyper-V的windows上使用toolbox或者是docker for mac 需要使用virtualbox作爲驅動。
- 如果使用docker for windows可以使用如下方式創建
選擇一個machine之後，選擇虛擬機交換管理器
之後創建外部網絡
點擊確定
這樣就可以創建machine了
docker-machine create -d hyperv --hyperv-virtual-switch "<NameOfVirtualSwitch>" <nameOfNode>下面是示例：
```shell

```但是筆者電腦出現了一個
Error creating machine: Error in driver during machine creation: exit status 1經過幾次嘗試懷疑爲內存不足，通過更改最小啓動內存解決問題。
