使用Docker Machine建立新的machine的方法如下。
範立環境：
- Windows 7 64Bit
- Docker Machine version 0.16.1, build cce350d7
- Oracle VirtualBox 版本 5.2.20 r125813 (Qt5.6.2)
注意：本範例的Docker Machine及VirtualBox是由Docker Toolbox安裝。
使用docker-machine create --driver=<driver-name> <machine-name>建立新machine。
<driver-name>為Macchine使用的driver名稱。<machine-name>為建立的machine名稱。
例如輸入docker-machine create --driver=virtualbox demo-docker以Oracle VirtualBox driver建立一個名稱為demo-docker的machine。
注意：如果VirtualBox內有預設的default machine正在運行，則建立新的machine時會卡在Waiting for an IP階段，所以先用docker-machine stop default把default machine停止再建立新的machine。
C:\>docker-machine create --driver=virtualbox demo-docker

To see how to connect your Docker Client to the Docker Engine running on this virtual machine, run: docker-machine env demo-docker
建立好後使用docker-machine ls列出現有的machine。第二個demo-docker即為新建的machine。
C:\>docker-machine ls
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
default - virtualbox Stopped Unknown
demo-docker - virtualbox Running tcp://192.168.99.101:2376 v19.03.5
