Answer 1

The error is related to that part:

In the default daemon configuration on Windows, the docker client must be run elevated to connect

• First, verify that Docker Desktop application is running. If not, launch it: that will run the docker daemon (just wait few minutes).

• Then, if the error still persist, you can try to switch Docker daemon type, as explained below:

With Powershell:

1. Open Powershell as administrator
2. Launch command: & 'C:\Program Files\Docker\Docker\DockerCli.exe' -SwitchDaemon

OR, with cmd:

1. Open cmd as administrator
2. Launch command: "C:\Program Files\Docker\Docker\DockerCli.exe" -SwitchDaemon

Answer 2

I had the same problem.

Starting the docker daemon resolved the issue. Just search for docker pressing windows key and click on "Docker Dekstop". Daemon should be running in a minute.

After starting up Docker Desktop, make sure the docker daemon status in the bottom left is green and shows RUNNING when you hover over it.

Answer 3

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.

Answer 4

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.

Answer 5

If you see docker desktop is STOPPED or Not Running screen at left side bottom, then do following

1. Open PowerShell with – Run as Administrator
2. Close Docker Desktop if it is open
3. Execute the following command on PowerShell “& 'C:\Program Files\Docker\Docker\DockerCli.exe' -SwitchDaemon”
4. Open Docker Desktop, it will get started.

I was facing this issue. I tried the above-mentioned steps and it worked for me. Thanks!

Answer 6

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 :)

Answer 7

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.

1. Go to Windows Start -> Search Box (Type here to search). There enter 'Services'. Among the listed items, click Services app.
2. Now search 'Docker Desktop Service' in the Services window opened. Right click on it and Start the service. Its status should be changed to 'Running'.
3. If step 2 gives error like 'the dependency service failed to start', then start all dependency services. For me, I had to start a service called 'Server'.
4. Double click 'Docker Desktop' icon in desktop. Now you will see 'Docker Desktop is running' in system tray.
5. Now run the command 'docker version' from Command Prompt or PowerShell. It should give clean output.
6. If any issue in step 5, run Command Prompt or PowerShell as administrator.

Above resolution assumes Docker is already installed and Hyper-V / Virtualization is enabled in your system.

Answer 8

Try resolving the issue with either of the following options:

Option A

Start-Service "Hyper-V Virtual Machine Management"
Start-Service "Hyper-V Host Compute Service"

or

Option B

1. Open "Window Security"

2. Open "App & Browser control"

3. Click "Exploit protection settings" at the bottom

4. Switch to "Program settings" tab

5. Locate "C:\WINDOWS\System32\vmcompute.exe" in the list and expand it

6. Click "Edit"

7. Scroll down to "Code flow guard (CFG)" and uncheck "Override system settings"

8. Start vmcompute from powershell "net start vmcompute"

9. Then restart your system

Answer 9

1.- Open the location of the shortcut:

2.- Right click and properties and add "-SwitchDaemon" to destiny

3.- Give administrator permissions, advanced options:

4.- Restart windows.

Answer 10

I have faced same issue, it may be issue of administrator, so followed below steps to setup docker on

windows10

.

1. Download docker desktop from docker hub after login to docker.Docker Desktop Installer.exe file will be downloaded.
2. Install Docker Desktop Installer.exeusing 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.
3. After install, go to -> computer management -> Local users and groups -> Groups -> docker-user -> Add user in members
4. Run docker desktop using Run as administrator
5. Check docker whale icon in Notification tab
6. run command >docker version Successfully using docker without any issue.

Answer 11

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

Answer 12

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:

1. Use command on cmd(Admin mode)

   docker-machine restart default
   

2. 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.

3. Go to the docker icon which will be on your windows tray (bottom right corner of the desktop)

4. Right click on the docker icon > Settings > Reset > Restart Docker

   It will take few moments

5. 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.

Answer 13

Reason : one reason may cause because we shut down the vmmem by command

wsl --shutdown

Solution : Simple Restart the Docker by right-clicking will fix the problem.

Answer 14

For me on Windows 11, editing %APPDATA%\Docker\settings.json to the following values and then restarting Docker Desktop did the trick (I am using WSL2, not Hyper-V):

Answer 15

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.

Answer 16

Open C drive in powershell Or Git bash and run below command

.\Program Files\Docker\Docker\DockerCli.exe -SwitchDaemon

Answer 17

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.

Answer 18

The same issue arrived when I started with the docker in windows 10. I was able to run docker --version successfully but failed when I tried to run docker pull docker/whalesay.
I tried many things suggested in the answers over here but my issue was resolved when I followed the below steps:
1 . Search for docker in windows and run docker desktop as administrator.
2 . Check the bottom-left docker symbol it should be green if the docker is running.
3 . If it's not running first install "wsl_update".
4 . Open the docker desktop and sign in with your docker credentials, when you are logged in you can see the server restarting and the bottom left logo turns green.
5. To check whether docker is running or not open PowerShell as administrator and run docker run hello-world.

Answer 19

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.

Answer 20

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.

Answer 21

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.

Answer 22

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.

Answer 23

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

Answer 24

That's worked for me on win10-home https://github.com/docker/for-win/issues/11967

1. Shutdown your service docker
2. Now execute this into the window command terminal
   RMDIR /S %USERPROFILE%\AppData\Roaming\Docker
3. Startup your service docker
4. Now click on your "Docker Desktop"

The "Docker Desktop" will now runnig ... done ... :)

Answer 25

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.

Answer 26

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

$ docker version Client: Version: 17.05.0-ce API version: 1.29 Go version: go1.7.5 Git commit: 89658be Built: Fri May 5 15:36:11 2017 OS/Arch: windows/amd64

Answer 27

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:

1. Open "Turn Windows features on or off"
2. If you are not sure how to do this please refer https://www.howtogeek.com/250228/what-windows-10s-optional-features-do-and-how-to-[turn-them-on-or-off/][1]
3. Turn Hyper-V off (uncheck box, making sure all sub-components are marked as off)
4. Hit "Ok" - and your machine will reboot.
5. When your computer starts up again, open "Turn Windows features on or off" and turn Hyper-V back on. Your machine will reboot again.

Now you can test by running docker hello-world image.

Answer 28

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:

ubantu version 20

After installation you can run command like docker -version or docker run hello-world in Linux terminal.

Answer 29

Make sure you have Hyper-V enabled, that was the problem in my case.

Answer 30

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
