Docker build error during connect

asked Oct 23, 2018 at 10:29

You can powerShell as admin.

Run this code:

cd "C:Program FilesDockerDocker"
./DockerCli.exe -SwitchDaemon

Running Powershell with elevated access solved my issue.

On Windows, go to the folder %homepath%.docker, open daemon.json and if debug is set to true then set it to false.

I had the same error as in the question and after I changed the above it worked again for me. After I got the error, I had been looking at the various docker settings and decided to set debug to false because I don’t need any daemon debug info for what I’m doing. I don’t know why it was set to true originally.

In my case, although I had the docker service running as admin and the service was shown as running, it was not.

Open the docker desktop app, click on the ‘troubleshoot’ icon. Check if the service is effectively running (bottom left). If it’s not, try to ‘clean/purge data’, and then restart the service. It worked for me!

Verify it by running docker run hello-world

same for me. service looks like running, but no client can connect. user- or elevated level of command line.

I had the same issue — I was able to resolve the issue by running power shell with Admin privs. I validated this was the same behavior for running the commands via elevated cmd prompt. It also enabled docker run hello-world command which was returning the error message ...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.

Solved for me. Run docker desktop app, check in notification. Setup if necessary…
Be happy.

Closing this issue. @Venkateshkuntla, if you still have the problem, please re-open and supply a diagnostics ID and detaisl of your setup (Docker for Windows version etc).

I have the same issue since I upgraded. Powershell in admin mode doesn’t help.

Same issue: 601A73D6-300C-4099-96C4-1D1FE8D18493/20180917131950

I fixed this issue by settings the certificate environment variables (for SSH/TLS):

SET DOCKER_CERT_PATH=%UserProfile%.dockermachinemachinesHypervDefault
SET DOCKER_MACHINE_NAME=HypervDefault
SET DOCKER_HOST=tcp://192.168.1.15:2376
SET DOCKER_TLS_VERIFY=1

The problem began when I created the «HypervDefault» machine, and deleted the «default» machine, which can be verified with docker-machine commands:

docker-machine ls
docker-machine env HypervDefault
FOR /f "tokens=*" %i IN ('docker-machine env HypervDefault') DO @%i

The above commands might need to run with Admin privileges (elevated), and make sure docker service is running: net start com.docker.service . Then the docker commands can run well:

docker ps
docker image ls
docker container ls --all

P.S: If your local IP Address (NAT) changes, for example: 192.168.1.3 —> 192.168.1.15 ; you can re-generate the certs (and it will auto update config.json for the machine respectively)
docker-machine regenerate-certs [machine-name]

@ducquoc does not work at step FOR /f «tokens=*» %i IN (‘docker-machine env HypervDefault’) DO @%i

@blueyestar :
That line, I use the «HypervDefault» as the machine name. In default case , the name is «default» . I think you should check that. (and adjust the variable environment to default respectively)

Another possibility is that some batch syntax (of cmd.exe) might not be run by PowerShell. In new versions of Docker they will use PowerShell syntax , so I think you can check the actual to be used by using the default (no machine name):

That will have output as a hint about the loop command to set environment variables. (though usually it’s only the IP change need to be updated)

@prabuddha93: Issue solved with your solution. Thank you

@zilurrane …your tip resolved the issue… See my note for my observation

cd «C:Program FilesDockerDocker»

Especially on windows machine when you see the above error after a docker update, try the above commands. It appears like the Docker Desktop UI may indicate that you are already using Linux Containers, but the update may have messed up that setting. Running the above commands will set to Linux Containers and there after you can work happily.

worked for me as well

open with powershell, It work for me.

Thanks!

This isn’t a workable solution to be honest for Linux containers users (assuming Docker is configured to use Linux containers), since it papers over an issue with Linux Containers by switching Docker over to use Windows containers.

There’s a problem with the interoperability of Docker, HyperV, Linux containers, and security levels (in my case) that are preventing me from making progress installing even the most basic docker containers (alpine, centos).

I’m going to look around a bit more for instructions, and if all else fails, screw it and install a Linux desktop on my corporate laptop in order to get my job done. I’ve been very disappointed with how much of a headache it’s been trying to get this to work on Windows, compared to OSX where everything «just worked out of the box».

For anyone else reading this thread, the error message is coming from HyperV.

cd "C:Program FilesDockerDocker"

Thanks for this. It solve my issue.

Thanks for this. It solve my issue.

As noted previously, this switches Docker from Linux to Windows containers. This doesn’t likely fix the underlying issue; it only papers over the fact that there’s an issue with HyperV interacting with Docker.

I’ll see if I can get Docker to work with my Windows 10 Pro desktop, given that I no longer have access to the machine that I ran into the original issues with.

I had the same issue very recently and was able to get it working again pretty easily:

I fixed it by using «Reset to factory defaults…» under Settings > Reset.

Of course I had to sign in again and all my containers were gone, so I had to re-download everything but that’s not a big deal, after all that is what docker is for, right!

I fixed this issue by settings the certificate environment variables (for SSH/TLS):

SET DOCKER_CERT_PATH=%UserProfile%.dockermachinemachinesHypervDefault

I am trying to run but not able to resolve the issue and secondly, after installing I’ve only docker toolbox inside program files because of windows 10 basic. Kindly help me to resolve the issue

I used Anaconda it worked but on cmd it failed.

In my case docker service was not running.

Steps to start:
Check Docker Desktop Service in Services (run > services.msc).
Sart that if not running.

I fixed this issue by settings the certificate environment variables (for SSH/TLS):

SET DOCKER_CERT_PATH=%UserProfile%.dockermachinemachinesHypervDefault

SET DOCKER_MACHINE_NAME=default
SET DOCKER_HOST=tcp://192.168.99.100:2376
SET DOCKER_TLS_VERIFY=1

This fixed the issue in Windows machine.

I had the same problem in Win Server 2019. I just opened Services and started Docker Engine service.
It is strangely, but the service does not starting after installation in his own.

After that it worked for admin user.
In order to add access for other user you can use this commands in powershell:

Install-Module -Name dockeraccesshelper
Import-Module dockeraccesshelper
Add-AccountToDockerAccess "domainuser"

You must already change EditionID from Core to Professional on register there OrdinateurHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersion

1. Run ‘dockerd.exe’ located in ‘C:Program FilesDockerDockerresources’ .
2. Now execute ‘docker version’ on a new powershell as administrator

Hey it fixed ,
Try to run this command :
docker-machine env
You will see this:
export DOCKER_TLS_VERIFY=»1″
export DOCKER_HOST=»tcp://192.168.99.100:2376″
export DOCKER_CERT_PATH=»C:UsersLAP13670-local.dockermachinemachinesdefault»
export DOCKER_MACHINE_NAME=»default»
export COMPOSE_CONVERT_WINDOWS_PATHS=»true»

Run this command to configure your shell:

eval $(«C:Program FilesDocker Toolboxdocker-machine.exe» env)

then run this command on your shell
eval $("C:Program FilesDocker Toolboxdocker-machine.exe" env)

=> Your problem was solved

I ran Docker Desktop and restarted my system and it worked.

I had same problem Windows 7. Tried some of the above, nothing worked. I fixed mine by going into Docker Toolbox folder, and double clicking start.sh
your installation directoryDocker Toolbox
Find start.sh
Double click start.sh
Wait for it to finish, then it’ll work.

I’m encountered same error in powershell on Windows10 Pro, Version 1909. I run docker on HyperV.

Docker Desktop Service was runnning. Restarting Docker Desktop Service finished successfully but same error appeared.
I restart OS, but same error appeared.

I ran docker desktop app, and did tutorial.
Tutorial has finished successfully, And after that, I successfully run docker command.

PS > docker —version
Docker version 19.03.8, build afacb8b

Installed Docker Desktop for Windows’s channel is «stable» one.

Expected behavior

Actual behavior

Information

• Diagnostic ID from «Diagnose & Feedback» in the menu.
• a reproducible case if this is a bug, Dockerfiles FTW
• page URL if this is a docs issue or the name of a man page
• host distribution and version (Windows version, build number, etc)

Steps to reproduce the behavior

1. Installing the latest version of Virtual Box resolved this issue.

I uninstalled the Hyper-V service and network adapters a while ago. I think that broke my docker install

I had the same error message and for me it was my antivirus program that interfered with running docker. I had to switch of the real time scan. (I use avira).

Run ‘dockerd.exe’ located in ‘C:Program FilesDocker’ work for me

or try

top-service docker
Get-ContainerNetwork | Remove-ContainerNetwork -Force
Start-service docker

I had the same problem but I’m using «minkube», then I just ran: «minikube docker-env» to see and se the correct env on windows prompt.

If anyone getting error like «error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/ … archive/tar: write too long»
the problem seems caused by symlinks in the folder.
I solved the problem by removing symlinks from the folder

This is an issue for me i downloaded the latest docker and Terraform. I cant use the Docker provider because the docker_host value isnt working ive look everywhere tried all solutions:

• turn on experimental cli mode
• using localhost as docker host
• using named pipe as docker host
• restarting docker service
• using dockertools for docker-machine to see VM host value

after using docker machine and creating a VM i noticed the VM was using IPv6? what does this mean

docker env output:

SET DOCKER_TLS_VERIFY=1
SET DOCKER_HOST=tcp://[fe80::215:5dff:fe10:900]:2376
SET DOCKER_CERT_PATH=C:Usersmyuser.dockermachinemachinesmydockervm
SET DOCKER_MACHINE_NAME=mydockervm
SET COMPOSE_CONVERT_WINDOWS_PATHS=true
REM Run this command to configure your shell:
REM     @FOR /f "tokens=*" %i IN ('docker-machine env mydockervm') DO @%i

useful info:

• i am on a brand new Windows Server 2019
• to create VM using docker-machine i had to create a external switch in HyperV Manager
• used docker-machine.exe create --driver hyperv --hyperv-virtual-switch "myexternalswitch" --hyperv-cpu-count "1" --hyperv-memory "1024" --hyperv-disk-size "20000" mydockervm to create VM
