docker-machine:没有机器名称，没有“默认"存在 [英] docker-machine: no machine name, no "default" exists

问题描述

我下载并安装了适用于Windows 1.12.1的Docker，后者又安装了docker-machine和docker-compose.我没有安装"Docker Toolbox"，因为它与已安装的重复，并且我的系统符合要求.

I downloaded and installed Docker for Windows 1.12.1 which in turn installed the docker-machine and docker-compose. I did not install "Docker Toolbox" since its a duplicate of what was installed and my system meets the requirements.

除了docker-machine之外，其他所有东西似乎都可以正常运行，我正在运行一个教程，当我运行各种docker-machine命令(例如"ip"或"env")时，会收到以下消息.

Everything seems to work fine except for docker-machine, I'm running through a tutorial and when I run various docker-machine commands like "ip" or "env" I get the following message.

Error: No machine name(s) specified and no "default" machine exists.

因此，当我执行"docker-machine ls"时，即使我确实安装了Hyper-V docker计算机并且docker命令正常工作，列表中也没有.

So when I do a "docker-machine ls" there is nothing in the list even though I do have a Hyper-V docker machine installed and docker commands work fine.

C:\tmp>docker-machine ls
NAME   ACTIVE   DRIVER   STATE   URL   SWARM   DOCKER   ERRORS
C:\tmp>

我在这里错过了什么吗?我是否错过了文档中的某些内容?如果可以的话，有人可以指出正确的方向来解决这个问题吗?

Am I missing something here? Did I miss something in the documentation? If so can someone please point me in the right direction to fix this?

感谢您的帮助，

推荐答案

Docker Machine是一个工具，可让您在虚拟主机上安装Docker Engine

Docker Machine is a tool that lets you install Docker Engine on virtual hosts

Docker机器就像在Vm上构建docker一样，因此首先必须创建一个Vm，以您的情况为例:

Docker machine just like building docker on a Vm, so first you have to create a Vm, in your case:

docker-machine create default
