docker-desktop
For win10 I had the same issue:
error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.39/images/load?quiet=0: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.
The docker service appeared to work. Restarting did not help. Running the binary from the installation directory as administrator helped.
In my case:
run as administrator -> C:\Program Files\Docker\Docker\Docker for Windows.exe
If you have installed docker on Windows 10 Pro with Hyper-V enabled and you are still not able to run Docker on Windows 10, then, as the error suggests, your docker daemon is not started.
The following steps helped me to start docker successfully:
Use command on cmd(Admin mode)
docker-machine restart default
Then you'll get a message something 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 (bottom right corner of the desktop)
Right click on the docker icon > Settings > Reset > Restart Docker
It will take few moments
Then you'll see the following message:
Docker is running with the green indicator
Note: If you already had Docker containers running on your system, then don't follow these steps. You may lose the existing containers.
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.
Faced the similar issue, having installed docker desktop on a Windows VM, running on WSL2.
Solution:
Updated the Windows to latest build and VMTools to the latest(11.2) version, fixed the issue, now docker is running non-stop.
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
I have faced same issue, it may be issue of administrator, so followed below steps to setup docker on
windows10
.
Docker Desktop Installer.exe
file will be downloaded.Docker Desktop Installer.exe
using Run as administrator
-> Mark windows container during installation else it will only install linux container. It will ask for Logout after logging out and login it shows docker desktop in menu.Run as administrator
I run in to the same problem. I solved this by enabling hyper-v.
Solved for me by running a docker desktop app, check-in notification. Setup if necessary.
$ net start com.docker.service
The Docker for Windows Service service is starting. The Docker for Windows Service service was started successfully.
$ docker version
$ net start com.docker.service
The requested service has already been started.
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.
You can start Kitematic when you get this error. It will display a button to reset the VM and will fix the issue.
Open C drive in powershell Or Git bash and run below command
.\Program Files\Docker\Docker\DockerCli.exe -SwitchDaemon
Try resolving the issue with either of the following options:
Start-Service "Hyper-V Virtual Machine Management"
Start-Service "Hyper-V Host Compute Service"
or
Open "Window Security"
Open "App & Browser control"
Click "Exploit protection settings" at the bottom
Switch to "Program settings" tab
Locate "C:\WINDOWS\System32\vmcompute.exe" in the list and expand it
Click "Edit"
Scroll down to "Code flow guard (CFG)" and uncheck "Override system settings"
Start vmcompute from powershell "net start vmcompute"
Then restart your system
If none of the other answers work for you, try this: Open up a terminal and run:
wsl -l -v
If you notice that there's a docker-desktop left hanging in the 'Installing' state, close Docker, run powershell as adminstrator and unregister docker-desktop:
PS C:\WINDOWS\system32> .\wslconfig.exe /u docker-desktop
Restart docker and hopefully it works. If it doesn't, try uninstalling docker first, then unregistering docker-desktop, and re-installing Docker.

For me the error was resolved by stopping a virtual Ubuntu instance that'd been running in Hyper-V:
The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.
Once Ubuntu instance had been stopped, and Docker Desktop had been restarted, my usual docker commands ran just fine.
PS: I had the idea to try this because of an Error Log that Docker Desktop had helpfully compiled and offered to send to Docker Hub as user feedback... the log appeared to indicate that my machine was short on RAM, and Docker was failing for this very simple reason. Killing the Ubuntu instance solved that.
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
For Installation in Windows 10 machine: Before installing search Windows Features in search and check the windows hypervisor platform and Subsystem for Linux
Installation for WSL 1 or 2 installation is compulsory so install it while docker prompt you to install it.
https://docs.microsoft.com/en-us/windows/wsl/install-win10
You need to install ubantu(version 16,18 or 20) from windows store:
After installation you can run command like docker -version
or docker run hello-world
in Linux terminal.

The error is related to that part:
In the default daemon configuration on Windows, the docker client must be run elevated to connect
You can do this in order to switch Docker daemon:
With Powershell:
& 'C:\Program Files\Docker\Docker\DockerCli.exe' -SwitchDaemon
OR, with cmd:
"C:\Program Files\Docker\Docker\DockerCli.exe" -SwitchDaemon
My solution was pretty simple. I noticed that docker was running linux containers instead of windows containers. What i did is switch to windows containers by right clicking on the docker icon in the system tray and choosing Switch to Windows Containers.
I too faced error which says
"Access is denied. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running."
Resolved this by running "powershell" in administrator mode.
This solution will help those who uses two users on one windows machine
In my case the WSL2 Linux-Kernel was missing, download, execute and restart:
https://docs.microsoft.com/de-de/windows/wsl/wsl2-kernel
Solved the problem.
I am using Windows 7 with Docker Toolbox and to fix it just open Docker Quickstart Terminal.

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.
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.
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.
Error Code:
error during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.29/version: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect . This error may also indicate that the docker daemon is not running.
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.
One of my friends was having a similar issue, we tried this and it worked.
Hyper-V, despite being listed under "Turn Windows features on or off" as being active, was not in fact active. This became apparent when running systeminfo under PowerShell, and seeing that the requirements were listed as met (which is not the output you would expect were Hyper-V actually running).Steps:
Now you can test by running docker hello-world image.
I got the same error for Docker version 19.03.12 and Windows 10. Resolved it by going through the below steps. Hope it helps others.
Above resolution assumes Docker is already installed and Hyper-V / Virtualization is enabled in your system.
After installing docker desktop into your pc (windows one). You may find up this location. What is actually does,? It starts the Docker Daemon via your CLI
"C:\Program Files\Docker\Docker\DockerCli.exe" -SwitchDaemon
I am using window 10 and i performed below steps to resolve this issue.
Above steps helped me to resolve the issue.
You need the admin privilege to run the service
I had the similar issue. The problem goes away when I run command prompt ( run as an administrator" , and type " docker version".

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 run "C:\Program Files\Docker\Docker\DockerCli.exe" -SwitchDaemon
and point Docker CLI to either Linux or Windows containers. This worked for me.
