I have docker installed.
I navigate to my project on git bash (windows) and type docker build .
and following error occurs:
error during connect: This error may indicate that the docker daemon is not running. open //./pipe/docker_engine: The specified file could not be found.
So I did some reaseach, did all steps from Windows Manual installation steps for older versions of WSL(https://learn.microsoft.com/en-us/windows/wsl/install-manual) but it seems like I have already met all of requirements
and the problem still occurs.

I installed Docker desktop latest version (Docker Engine - v20.10.22).
pointed it to search containers in Windows.
run the command docker --help (it is working okay)
Now when I am trying to run any command I am getting this error.
docker Error response from daemon: open
\.\pipe\docker_engine_windows: The system cannot find the file
specified.
did by any chance someone gets this error and got it resolved ?
I am trying to start my docker by running shortcut of docker desktop but it shows the message Docker Desktop Stopping and never returns anything else.
Docker version gives me Docker version 20.10.16, build aa7e414
Docker build gives me this below error -
docker build .
error during connect: This error may indicate that the docker daemon is not running.: Post “http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/build?buildargs=%7B%7D&cachefrom=%5B%5D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&labels=%7B%7D&memory=0&memswap=0&networkmode=default&rm=1&shmsize=0&target=&ulimits=null&version=1”: open //./pipe/docker_engine: The system cannot find the file specified.
I had the same probably using Windows. To fix it, I had to make sure WSL 2 was installed properly:
https://learn.microsoft.com/en-gb/windows/wsl/install-manual#step-4---download-the-linux-kernel-update-package
If it's already installed on your machine, try uninstalling and reinstalling it.
Then, open Docker Desktop and click on the 'troubleshoot' icon in the top right corner. Click 'Clean/Purge Data' and select 'WSL 2' only and click 'delete'. Then restart your machine and it should work. Hope that helps!
Setup:
Ubuntu 20.04 distro running inside WSL2 (5.4.72-microsoft-standard-WSL2)
VS Code version 1.55.2 installed in Windows
Docker version 19.03.8, build afacb8b7f0 installed in WSL2
docker-compose version 1.29.0, build 07737305 installed in WSL2
Remote-Containers Extension for VS Code v0.166.1 installed locally (I could not find an option to explicitly install this inside WSL2, but I am not sure if this even matters, see below)
Original error:
When I open the command palette and enter Remote-Containers: Rebuild and Reopen in Container, I get the error `The 'docker' command was not found. Make sure Docker is installed' in a pop up window.
What I tried:
Attempt 1
First, I thought that the Remote-Containers extension wants to execute the docker commands inside windows and not WSL2. Since I don't have Docker Desktop installed on Windows, it is impossible to execute docker commands in Windows. So I tried downloading a specific version of the the Remote-Containers extension file from the marketplace v0.165.0 I believe, copying it into the VS extension folder inside WSL2 /home/kevinsuedmersen/.vscode-server/extensions and installing it manually from the VS Code Extension panel. However, this also installed the Remote-Containers extension locally, so probably on Windows. I am not sure if locally means that this extension is available globally, but nevertheless, I am still getting the error that the docker command is not found as explained above.
Attempt 2
I notice that when I open a PowerShell on Windows, I can use the docker daemon inside WSL2 by prepending wsl to all docker commands, e.g. wsl docker run hello-world. So, I went to the VS Code and in settings (Settings > Remote > Containers > Docker Path), I changed the docker path from docker to wsl docker, but then, I got this error Docker Desktop WSL 2 backend required. This is even the case on another laptop, where I actually have Docker Desktop installed and the WSL2 backend enabled.
Attempt 3
I tried changing the docker path in VS code to the full path of the docker socket in WSL2 /var/run/docker.sock, but then I got the error Current user does not have permission to run 'docker'. Try adding the user to the 'docker' group. My current user kevinsuedmersen is already member of the docker group.
Any advice or directions are greatly appreciated.
Answer was given on the GitHub Repo of the VS-Remote-Container Extension here: https://github.com/microsoft/vscode-remote-release/issues/4914
We are using Windows OS 7 to develop an application using tech stack viz. docker, spring, java8, gradle etc. We have installed the docker toolbox on our machine.
Now the base image is located in our docker repository of our organization. But the docker is not able to identify the host.
We are able to connect to our repository from docker installed on a linux machine. In that case we have made changes in these 2 files viz.
1.
/etc/systemd/system/docker.service.d/daemon.conf
here we have added http_proxy and https_proxy.
2.
/etc/docker/daemon.json
here we have mentioned the host name as
{"insecure-registries":["<host-name>"]}
But we are not able to find these files in docker tool-box in windows 7.
Please let us know how to resolve this issue.
We are getting the following error in dockerBuildImage gradle task currently wherein it is not able to download the base image.
:dockerBuildImage FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':dockerBuildImage'.
> Could not build image: Get https:<host-name>/v2/: x509: certificate signed by unknown authority
Please advise.
The following worked for me in docker toolbox
change the file /var/lib/boot2docker/profile to include following text:
--insecure-registry=<host1-name>
export "NO_PROXY=<host-name>"
export HTTP_PROXY=<value>
export HTTPS_PROXY=<value>
Then restart the docker-machine to make these changes visible.
I'm trying to use the OpenFOAM docker image. I installed everything correctly and when I try to run OpenFOAM_Start I get the error:
Started machines may have new IP addresses. You may need to re-run the docker-machine env command.
Error response from daemon: No such container: of_1712
Error: failed to start containers: of_1712
Error: No such container: of_1712
Stopping "default"...
Machine "default" was stopped.
Then I ran docker-machine env command and I got the error:
Error checking TLS connection: Host is not running
I would appreciate if you could help me know what is the problem and how I can solve it.
P.S. Hopefully this is not off-topic. Please let me know if I should ask this question in a different stackexchange.
I found the solution but I'm still not sure what the error above mean. As indicated in the OpenFOAM installation guide, right after installation of the docker image you should run the:
"OF_Create_Env"
shortcut on the Desktop. A shell will open and close automatically,
completing setup of the user working environment. This step is mandatory
only on the first occasion of OpenFOAM for Windows installation.
Then you can run OpenFOAM_Start again and it just works.
