Solutions:
1) For Windows 7 Command Window(cmd.exe), open cmd.exe with run as administrator and execute following command:
docker-machine env --shell cmd default
You will receive following output:
SET DOCKER_TLS_VERIFY=1
SET DOCKER_HOST=tcp://192.168.99.100:2376
SET DOCKER_CERT_PATH=C:\Users\USER_NAME\.docker\machine\machines\default
SET DOCKER_MACHINE_NAME=default
SET COMPOSE_CONVERT_WINDOWS_PATHS=true
REM Run this command to configure your shell:
REM @FOR /f "tokens=*" %i IN ('docker-machine env --shell cmd default') DO @%i
Copy the command below and execute on cmd:
@FOR /f "tokens=*" %i IN ('docker-machine env --shell cmd default') DO @%i
And then execute following command to control:
docker version
2) For Windows 7 Powershell, open powershell.exe with run as administrator and execute following command:
docker-machine env --shell=powershell | Invoke-Expression
And then execute following command to control:
docker version
3) If you reopen cmd or powershell, you should repeat the related steps again.

I know this question was long ago but I found no proper explanation and solution, so hopefully, my answer is useful :)
Assuming you install Docker Toolbox on Windows, both docker
and docker-machine
commands will be available. Often, people get confused when to use either of these.
The docker
commands are used only within a virtual machine to manage images. The docker-machine
commands are used on the host to manage the Linux VMs.
So, please use docker-machine
commands on your Windows machine. Use docker
command inside your VM. To use the docker
commands, for example, docker ps
, you either can open Docker Quickstart Terminal or run these on your cmd/bash/PowerShell:
docker-machine run default
/assuming default is your Linux VM/
docker-machine ssh default
This will start boot2docker and you will see the docker icon on the command line. Then you can use docker
commands.
Good luck :)

You can C:\Program Files\Docker\Docker>DockerCli.exe -SwitchDaemon and point Docker CLI to either Linux or Windows containers. This worked for me.
回答4:
For me the issue was virtualization was not enabled.
On windows 10: Go to task manager -> Performance -> CPU and you should see as section as "Virtualization : Enabled"
If you do not see this option, it means that virtualization has not been enabled.
Another interesting thing to note is you must have Hyper V enabled. However as I was using parallels desktop, I had to enabled to "Nested Virtualization" for Hyper V to be "truly enabled". So if your windows is a VM, check out the settings for Parallels (or whatever you're using) that nested virtualization is enabled.
回答5:
I had the same issue lately. Problem was Security Software(Trendmicro) was blocking docker to create Hyperv network interface. You should also check firewall, AV software not blocking installation or configuration.
回答6:
If you have installed docker on Windows 10 Pro with Hyper-V enabled and still you are not able to run Docker on Windows 10, then as the error suggests that your docker daemon is not started. Follow following steps it helped me to start docker successfully-
1. Use command on CMD(Admin mode)
docker-machine restart default
then you will get msg like "open C:\User\{User_name}\.docker\machine\machines\default\config.json: The system cannot find the file specified."
Go to the docker icon which will be on your windows tray(Right corner of the desktop).
Then Right click on the docker icon -> setting-> Reset -> Restart Docker
It will take few moments
then you will see the message "Docker is running with the green indicator".
Note- If you have already had running Docker containers running on your system then don't follow these steps. You may loose the exiting containers.

I am using Windows 7 with Docker Toolbox and to fix it just open
Docker Quickstart Terminal.

For me, the answer was to turn off a VPN service.
While at work, connected to a VPN, I get the error mentioned. I switch off the VPN, and then docker worked as expected on Windows 10. The command below (when complete) drops you to the interactive python prompt ">>>" and pre-installs simplejson
and requests
docker run --rm -ti -v `pwd`:/tmp jfloff/alpine-python:2.7-slim -p simplejson -p requests
回答9:
I run in to the same problem. I solved this by enabling hyper-v.
- Enable virtualization in BIOS
- Install hyper-v
回答10:
Try running the following from an elevated command prompt:
SET DOCKER_CERT_PATH=C:\Users\[YourName]\.docker\machine\machines\default
SET DOCKER_HOST=tcp://[yourDockerDeamonIp]:2376
SET DOCKER_MACHINE_NAME=default
SET DOCKER_TLS_VERIFY=1
SET DOCKER_TOOLBOX_INSTALL_PATH=C:\Program Files\Docker Toolbox
You might also find that even without setting those env variables, running commands from the docker quick start terminal works no problem.
回答11:
I had the same error on Windows. Turns out I was missing the Container feature.
Install-WindowsFeature Containers
Restart server
When up and running ensure the Docker service is running
回答12:
if you are in windows try this
docker-machine env --shell cmd default
@FOR /f "tokens=*" %i IN ('docker-machine env --shell cmd default') DO @%i
for testing try
docker run hello-world

I was getting same errors after an install on Windows 10. And I tried restarting but it did not work, so I did the following (do not recommend if you have been working in docker for awhile, this was on a fresh install):
1) Find the whale in your system tray, and right click
2) Go to settings > Reset
3) Reset to factory defaults
I was then able to follow the starting docker tutorial on the website with Windows 10, and now it works like a charm.
回答14:
I am using window 10 and i performed below steps to resolve this issue.
- check Virtualization is enabled from taskmanager-->performance
- Restarted the docker service
- Install the latest docker build and restarted the machine.
- Make sure the docker service is running.
Above steps helped me to resolve the issue.
回答15:
This is the final solution.. its works for me...!!
1) Find the whale in your system tray, and right click
2) Go to settings > Reset
3) Reset to factory defaults
回答16:
1st start Powershell "as Administrator" that will also prevent the error you got from docker version
.
The try to start the docker service: start-service docker
If that fails delete the docker.pid file you will find with cd $env:programfiles\docker; rm docker.pid
Finally you should change HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization\Containers\VSmbDisableOplocks
to 0
or delete the value.
回答17:
You can start Kitematic when you get this error. It will display a button to reset the VM and will fix the issue.
