I am new to Docker and after writing docker version in cmd I got this error,
error during connect: This error may indicate that the docker daemon is not running.: Get "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/version": open //./pipe/docker_engine: The system cannot find the file specified.
The following steps solved this problem:
Open cmd as administrator
Launch command: "C:\Program Files\Docker\Docker\DockerCli.exe" -SwitchDaemon
some times docker might be disabled from starting on boot or login so in the windows search bar or when clicking the WinKey and starting to type Dock... like showen in the picture below, Then press Enter to start the Docker Daemon
Try running dockerd in a separate terminal and then try running this command.
To avoid doing this every time you can go to services -> find Docker -> select Startup Type as Automatic (Delayed) and reboot the machine.
Simple Solution: Just open Powershell and type dockerd which will start the daemon and you shall be able to use the docker now without errors.
On Windows, reason behind this issue is that Docker is not started. I tried couple of solution provided on multiple online portal to start it. What worked for me is:
In Docker Desktop if you are already logged in as a user, logout from there
Again login to docker desktop with docker account
When we login to docker account, it internally triggers the restart. So resulting if it's not started, it will start the docker for us.
I had this, but when I used a command shell elevated to Administrator, docker version was fine.
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.
this error in windows 10
step 1
pls install (https://learn.microsoft.com/en-us/windows/wsl/install-manual#step-4---download-the-linux-kernel-update-package) Download the latest package:
this link WSL2 Linux kernel update package for x64 machines
then restart then automatically running
In my case,
I download the this github repo.MaxySpark
Closed all the application related to docker.
1.Click on docker.reg file in the downloaded repo.
2.Click on yes->yes->ok to merge.
3.Again open the Docker Toolbox and run docker run hello-world
Open cmd as administrator
Launch command: C:\Program Files\Docker\Docker\DockerCli.exe -SwitchDaemon
It simply means that your docker application is not running or you have not logged in to docker application, or docker desktop service is not running .
1: Just open Docker desktop application, login with docker credentials.
2: if already logged in and still getting this error, go to windows + r ==> and type 'services.msc', and restart the docker desktop service.
All done.
It can be kernel problem:
You need to update WSL2 Linux kernel update package for x64 machines
Follow this tutorial:
https://linuxhint.com/resolve-docker-daemon-not-running/
and before execute "docker run hello-world" command, dont forget restart docker

i installed docker on my laptop (windows 10) and docker is running in the background and i can do anything in docker command prompt (pull/push/build,etc); however, if i want to open the docker dashboard by right clicking the docker icon and selecting either dashboard or setting
it won't open any docker GUI. I should normally see the following, but nothing happens on my laptop.
Is there any step missing so i can see the Docker UI?

You can powerShell as admin.
Run this code:
cd "C:\Program Files\Docker\Docker"
./DockerCli.exe -SwitchDaemon
Running Powershell with elevated access solved my issue.
Usually this error means the Docker daemon that is docker services is not up and running.
Make sure docker is running by issuing below command in power shell in elevated mode.
docker run hello-world
A response as hello from docker will be printed on console.
Else start the docker by double clicking the docker app from start menu.
Below is the snapshot of graphically up and running docker daemon.
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
Fow Windows:
Launch command: "C:\Program Files\Docker\Docker\DockerCli.exe" -SwitchDaemon
This error is because of organisation network certificates which are installed in local machine. Beacuse some companies restricted network by installing certificates.
docker daemon service is not running on my machine and when I start the service, this error us resolved.
I had faced the same error, the following worked for me:
In the windows taskbar, the docker icon was red in color saying Out of Memory...
In the Docker Desktop App, goto
Settings -> Resources -> Disk Image Size -> decrease the space allocated -> Apply & Restart
This did happen to me while i was using docker today for the first time. I fixed by opening up the docker app in the PC and signing and selecting the necessary subscription plan.
Open docker with docker <homepath>. Simply upgrade docker and then run this command
docker-compose up -d
you will be able to solve the specified path error.
docker.errors.DockerException: Error while fetching server API version: (2, 'CreateFile', 'The system cannot find the file specified.')

Doing the above solved the error.
Yo,
open docker app > settings > Docker engine > "debug": true,
debug was false initially, after changing it to "true" it worked.
Thanks.

I am aware there are a lot of questions about running Docker on windows, however this question is about running the brand new Docker for Windows, on Windows.
In my case I am using Windows 10 Pro 64 bit. According to the site this version should be supported.
I have been following a tutorial I found here:
https://prakhar.me/docker-curriculum/
I also tried following the official guide of course: https://docs.docker.com/docker-for-windows/
In both tutorials I get the same error message when trying to assign a port using either the -P parameter or when trying to specify a port -p 8080:5000:
In the official guide I run docker run -d -p 80:80 --name webserver nginx and get:
C:\Program Files\Docker\Docker\Resources\bin\docker.exe: Error response from daemon: driver failed programming external connectivity on endpoint webserver (f9946544e4c6ad2dd9cb8cbccd251e4d48254e86562bd8e6da75c3bd42c7e45a): Error starting userland proxy: mkdir /port/tcp:0.0.0.0:80:tcp:172.17.0.2:80: input/output error.
Following the unofficial guide i run docker run -p 8888:5000 prakhar1989/catnip and get basically the same error:
C:\Program Files\Docker\Docker\Resources\bin\docker.exe: Error response from daemon: driver failed programming external connectivity on endpoint focused_swartz (48a0c005779c6e89bf525ead2ecff44a7f092495cd22ef7d19973002963cb232): Error starting userland proxy: mkdir /port/tcp:0.0.0.0:8888:tcp:172.17.0.2:5000: input/output error.
If I don't try to assign a port the container will run, but then I don't know how to access it.
The docker version I am running:
Docker version 1.12.3, build 6b644ec`
docker-compose version 1.8.1, build 004ddae`
docker-machine.exe version 0.8.2, build e18a919`
Any help would be very appreciated. Thank you.
Here's a new twist.
The last Windows 10 update (Fall Creators Update, 2017) has a new "feature". It automatically starts any applications that were running when you last shutdown.
This reconstitutes Docker for Windows in a bad state. That made it appear those ports were in use by something else - it was the ghost of itself. This explained why those ports were still in use even though I stopped/started my containers and even reboot!
The solution in this case is to simply restart Docker daemon.
To prevent this after the next shutdown, don't use the shutdown button. Type this instead:
shutdown /s /t 0
This bypasses the new feature.
See the answer from Jason[MS] in this thread:
https://answers.microsoft.com/en-us/insider/forum/insider_wintp-insider_perf-insiderplat_pc/programs-autostart-after-boot-in-windows-10-fall/09dd8d3e-7b36-45d1-9181-6587dd5d53ab
Here's one guy's workaround (from the end of this thread - haven't tried it myself):
http://www.icttoolbox.nl/info/stop-windows-10-creator-fall-reopening-programs-reboot/
Restarting the Docker daemon fixes this problem temporarily, but to get rid of it ultimately I had to disable Windows 10 fast startup, which is the feature #biscuit314 described.
To disable Windows 10 fast startup, get to the Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable > Uncheck Turn on fast startup (recommended) and hit Save changes
This is caused by a port numbering conflict: github issue here https://github.com/docker/compose/issues/3277
Essentially the port is in use! The reason resetting worked is because it wiped other mappings off.
1) Stop all the running containers docker stop $(docker ps -a -q) then
2) Stop the Docker on your machine & restart it.
Then run the required command. This will solve the issue.
If its in windows OS, Please do restart the Docker
This has fixed the issue for me
For Linux - Debian Users,
Use docker stop $(docker ps -a -q) only when you know whether you want to stop all the containers or not.... If yes then please run docker rm $(docker ps -a -q) to remove containers ....
Then stop the docker daemon - systemctl stop docker
Then start docker daemon - systemctl start docker
Also verify whether docker daemon is up or not - service docker status
After following all above mention steps you should be fine.....
I got the same issue before on window 10.
Restart docker, it works
Try stopping docker and initiating it again on administrator mode. After it starts open power shell on administrator mode as well.
Because the error says "mkdir" maybe this will solve your problem. Im not sure but it worked for me.
In the case of using -P a port conflict does not seen to be the reason for the error once -P will chose ports randomly. The error it self wasn't quite friendly to me but because I saw the mkdir word on it I imagined it might be a permission error, thats why I restarted docker on administrator mode and started power shell on administrator mode.
I tried all the suggestions on this issue: killing all the containers, restarting Docker Desktop, disabling "Fast Startup," restarting my computer, making sure "Experimental Features" were disabled. None of that stuff worked.
I did eventually get it running. Here are some things you may want to try (because I'm not sure what actually fixed it).
Find "Docker Desktop" and right-click to "Run as Administrator..."
Pay attention to the port that it's complaining about. Some people say this could just be Docker's unfriendly way of saying "that port is in use." In my case, the port was 80. I went into the Services on Windows Pro and disabled the "World Wide Web Publishing Service" just to be safe.
If you are here because you have this issue in Visual Studio 2019:
According to this post, the VS team is preparing a fix for this issue in 16.5 version, meanwhile, you can add the property "publishAllPorts": true in your launchSettings.json, for example:
"Docker": {
"commandName": "Docker",
"launchBrowser": true,
"launchUrl": "{Scheme}://{ServiceHost}:44374", #<== Set a fixed port
"environmentVariables": {
"ASPNETCORE_URLS": "https://+:44374;https://+:5000",
"ASPNETCORE_HTTPS_PORT": "44374"
},
"publishAllPorts": true, #<== This is equivalent to the -P flag in 'docker run'
"useSSL": true
}
Notice that the property "httpPort": XYZT is not defined. Having it defined will make the workaround not work.
It worked for me with this setup:
Windows 10 1709 Build 16299.1747 with Fast Start OFF
Docker Desktop 2.2.05 (43884)
Docker Engine 19.03.8
Visual Studio 2019 Enterprise 16.5.4.
Microsoft.VisualStudio.Azure.Containers.Tools.Targets 1.10.8
I realized that the command VS was creating, contained the -p parameter twice, one with the port I specified and another with port 80, like this: -p 3010:80 -p 3010:3010.
After adding publishAllPorts it now creates the container and I can remotely debug it.
This is what worked for me after trying every thing. Seems we need to kill the running process.
Exit docker, right-click the icon Quit Docker Desktop
Open the windows task manager, find and kill the process com.docker.backend.exe
restart docker, double-click the icon to open the Docker Desktop
