问题描述
我能够安装docker，docker-compose和docker-machine
I am able to install docker, docker-compose and docker-machine
但是，当我尝试运行时
root@DESKTOP-51NFMIM:~# docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
是否有解决此问题的建议？
Is there any suggestion for solving this problem?
推荐答案
在此信息上找到了解决方案：
Found the solution on this post: https://blog.jayway.com/2017/04/19/running-docker-on-bash-on-windows/
在另一台机器上的引擎上运行docker实际上非常容易，因为Docker可以公开CLI可以附加到的TCP端点。
Running docker against an engine on a different machine is actually quite easy, as Docker can expose a TCP endpoint which the CLI can attach to.
默认情况下，此TCP终结点处于关闭状态。要激活它，请右键单击任务栏中的Docker图标，然后选择设置，然后选中在不带TLS的tcp：// localhost：2375上公开守护程序旁边的框。
This TCP endpoint is turned off by default; to activate it, right-click the Docker icon in your taskbar and choose Settings, and tick the box next to "Expose daemon on tcp://localhost:2375 without TLS".
完成后，我们需要做的就是指示Bash下的CLI连接到Windows下运行的引擎，而不是连接到Bash下运行的不存在的引擎，就像这样：
With that done, all we need to do is instruct the CLI under Bash to connect to the engine running under Windows instead of to the non-existing engine running under Bash, like this:
$ docker -H tcp://0.0.0.0:2375 images
有两种方法可以使其永久化–为上述命令添加别名或导出一个环境变量，该变量指示Docker在哪里找到主机引擎（注意：请确保在下面使用单撇号） ：
There are two ways to make this permanent – either add an alias for the above command or export an environment variable which instructs Docker where to find the host engine (NOTE: make sure to use single apostrophe's below):
$ echo "export DOCKER_HOST='tcp://0.0.0.0:2375'" >> ~/.bashrc
$ source ~/.bashrc
现在，从Bash运行docker命令
Now, running docker commands from Bash works just like they’re supposed to.
$ docker run hello-world
成功的响应：
Hello from Docker!This message shows that your installation appears to be working correctly.
