failing to start docker engine open //./pipe/docker_engine - windows

I'm receiving the following error in docker on windows 10 laptop.
I've try to reinstall and restart but nothing helps.
The docker service is running OK but what i understand that i have a problem with the docker daemon (from what i read)
The whole issue started when i run the 2 commands:
net stop com.docker.service
net start com.docker.service
from there on i keep getting the error below and cannot solve it.
C:\Users\xxxx>docker images error during connect: Get
http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.30/images/json: 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.
anyone succeed to solve it?

docker client must be run elevated to connect
This indicates that you do not have enough permissions. Try starting the terminal as administrator.

I run Docker remotely as a non admin user.
For this the user running docker should have full permission to location where Docker is installed.
User should be part of docker_users group
docker daemon runs on port 2375 by default. Try to whitelist this port. Allow incoming connections to 2375 in Windows Firewall settings
Restart your docker daemon and Docker service.
Restart the running Docker instance[Docker for Windows] if required. You do not have to reinstall.

Docker container as Windows service start before login

I have created a container via Docker Desktop on a Windows PC and would now like to start this container like a service or daemon during system startup. If successful, the container would be accessible from its own network via 192.168.178.35:80 without a user having to log in and start Docker.
This is really not my favorite topic but I tried to learn about Windows task scheduling.
As you can see here I wrote a short powershell script that starts Docker Desktop.exe and then the container.
start "C:\Program Files\Docker\Docker\Docker Desktop.exe"
sleep 10
docker start 9df2014cdb06
exit
I assigned the script to the SYSTEM user in the task scheduler. (see screenshot 1)
Unfortunately, 192.168.178.35:80 cannot be reached when the system is booted. When I log in, I see that various Docker background processes in Task manager. (See screenshot 2).
However, Docker is no longer accessible in Powershell. (See error message)
PS C:\WINDOWS\system32> docker ps
error during connect: In the default daemon configuration on Windows, the docker client must be
run with elevated privileges to connect.: Get "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/containers/json":
open //./pipe/docker_engine: The system cannot find the file specified.
And starting it from the desktop icon does not succeed either. Instead, the message appears that Docker is already running.
But my container is not running.
How do I get my container running and accessible on Windows after system startup and before user login?

Auto Start Docker on Windows reboot

I created a task to autostart docker on windows server using TaskScheduler
referred to https://stackoverflow.com/a/59467740/12768108
As admin created a local "task-executor" user and added it to the administrator group.
As admin added the same user to the docker-users group
Now after logging into the system using another user account(already in the docker users group), I run the task manually from the task scheduler the docker services started with daemon mode and I am able to run all docker commands like "docker ps".
But when restarting the machine it only started two services of docker ie "docker desktop" and "docker desktop backend" and not others, also when tried to run docker ps gives below error
error during connect: This error may indicate that the docker daemon is not running.: Get "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/containers/json": open //./pipe/docker_engine: The system cannot find the file specified.
I have also tried https://github.com/tfenster/dockeraccesshelper but this helps me achieve only point 1 of the description.
Can someone please let me know what i am missing here ?

Permissions to run docker container on self-hosted windows azure devops agent

In an azure devops build pipeline running on a self-hosted windows agent, I am trying to execute a tool that run a docker container.
Unfortunately I get this error :
Failed to start: failed to create container: Error response from daemon: CreateFile c:\Users\BUILDAGENT\.aerokube\selenoid: Access is denied.
The build agent is configured with its own windows local user "BUILDAGENT", so he has permissions on the C:\Users\BUILDAGENT\ folder
Looking at the process manager, I see that except com.docker.service, the others docker processes are running with the user that launched the Docker Desktop (my coworker).
If I restart windows and relaunch docker myself, the settings selected by my coworker ("Disk Image Location" for instance), are not restored...
Is there a way to make docker run as a daemon on startup with a specific user (service or system user, but not mine or my coworker) ?
Once this is done I guess I just have to give permissions for that specific user on the C:\Users\BUILDAGENT\ folder to solve my issue, right ?
Update :
I added my BUILDAGENT user in docker-users group, and it solves the permission issue, but I still would like to run docker as a service, instead of login as my local user to launch it with its GUI...
but I still would like to run docker as a service, instead of login as my local user to launch it with its GUI
You could try to create a task scheduler to run docker with that specific user when your PC starts.
Please check this thread How to create an automated task using Task Scheduler on Windows 10 for some more details.
In this case, docker will start automatically every time you start your computer.

Docker on Win10 - is it possible to have multiple terminals?

I am new to Docker - installed DockerToolbox on Win10. And managed to run some basic docker examples. But I cannot seem to figure out how to access same container from multiple command line windows.
Quick online search suggested finding container ID (e.g. 2c7e29b9b666) via
docker ps
then running (I presume in new command window)
docker exec -it 2c7e29b9b666 bash
but that does not work in Win10.
Error message received is:
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
Edit: in the first window I started docker machine via:
docker-machine create --driver virtualbox tombox
and I can see 'tombox' in second window if I do:
docker-machine ls
Do I need to somehow reference 'tombox' when running docker commands in second window?

Docker unreachable after computer sleep

I have just installed docker using docker-toolbox 1.8.2 on Windows 10.
Due to due to this issue I had to recreate the docker image using these commands
docker-machine rm default
docker-machine --native-ssh create -d virtualbox default
After that it has been working fine, except for one problem:
When the PC has gone to sleep and then wakes again, the docker commands can no longer connect. Example:
> docker images
An error occurred trying to connect: Get https://192.168.99.100:2376/v1.20/images/json:
dial tcp 192.168.99.100:2376: ConnectEx tcp: A connection attempt failed because the
connected party did not properly respond after a period of time, or established connection
failed because connected host has failed to respond.
However the docker-machine lists the machine as running:
> docker-machine ls
NAME ACTIVE DRIVER STATE URL SWARM
default * virtualbox Running tcp://192.168.99.100:2376
I can also confirm in VirtualBox that the VM screen seems to be active.
I have tried starting and stopping the machine, but that does not help
C:\x> docker-machine stop default
C:\x> docker-machine start default
Starting VM...
Started machines may have new IP addresses. You may need to re-run the `docker-machine env` command.
C:\x> docker-machine env default --shell=powershell
Ironically, the last command hangs, so I never get any environment settings.
The only thing that helps is to restart the whole PC. But that should be unnecessary?
I have also posted this as an issue on the docker github repository,but that was closed. A related issue seems to be this one, but no workaround or solution has been posted for Windows.
After hous of fighting with VirtualBox + Docker Toolbox, I finally found the way, how to make Docker working again (even without restarting all the containers):
Wake up PC from sleep
Try docker images (won`t work)
Open VirtualBox -> Close VM with saving state (CTRL+V)
Run your VM again
Try docker images again (now should work)
Please note: All steps are in VirtualBox only! Running docker-machine restart default will create another host-only adapter, which is something you do not want. If you did it anyway, delete all additionally created adapters (File->Preferences->Network on VirtualBox), then follow steps 1-5.
I have experienced the exact same symptoms on Windows 8.1... The thing is that it's not really a docker-specific issue, but more how Windows manages the VirtualBox network adapters after sleep (I think...). The culprit in my case is that the network adapter's addresses were becoming private after sleep (they became 169.* addresses).
Credits to this guy who gave me the idea: http://lyngtinh.blogspot.ca/2011/12/how-to-disable-autoconfiguration-ipv4.html
Fix:
Start a command prompt as Administrator
Find out the "useful" network adapters: ipconfig /all. The useful ones in my case were the ones labeled "VirtualBox Host-Only Ethernet Adapter" that didn't have private ips (not starting with 169.*).
Run this command and note the "Idx" of the useful VirtualBox network adapters: netsh interface ipv4 show inter.
Run this command to disable the IP auto configuration: netsh interface ipv4 set interface <idx> dadtransmits=0 store=persistent. Replace <idx> with each index found in the previous step.
Restart Windows
Afterwards, I was able to docker-machine start default, then docker-machine env default --shell cmd, put the PC to sleep, wake up and run docker-machine env default --shell cmd again.
I found that removing 'host only adapter' (File->Preferences->Network on VirtualBox), and restart the docker-machine helps.
Not a real solution. But probably better over restart the computer.
Having tried all the other answers here, and having varying but not consistent success, the following seems to reliably bring it back for me after this problem occurs.
Open a powershell/command window (I have most success if I run all docker-machine commands in a powershell window opened as administrator, I don't know if that's important or not) then run (where "dev" is the name of your docker machine instance):
docker-machine ssh dev
Then on the terminal that is opened, run:
sudo shutdown -r now
When the machine restarts, it seems to refresh the network and work correctly. Note, however, that simply running docker-machine restart dev did not have the same effect for me.
Your machine needs to be running before you can do the ssh, so if it's not running, execute docker-machine start dev before trying to SSH.
Had the same problem on Windows 8.1 and docker toolbox 1.12.0
None of the above solutions worked for me, too.

Found another way to make docker work after system wake up:
In the docker Quickstart Terminal window, stop docker process Ctrl-C (if it is still running)
Run command docker-compose down
Shut down docker with docker-machine stop default
Exit terminal window Ctrl-D
Run Quickstart Terminal again and do all subsequent steps you need.
This worked for me, on Windows host machine.
Configure your network adapter to
1) Allow the network adapter to wake the computer,
2) Allow a magic packet to wake the computer,
3) Allow IPV6

Also, on virtual box network settings, go to advanced, and allow promiscuous mode to VM machines, or allow all
