On qemu, I'm trying to run Docker with Yocto project and there isn't any network connectivity on qemu. But I'm unable to start the daemon.
I have cloned hello-world file and saved it as a tar using docker commands. I have added the tar file to my image which already contains docker-ce on qemu.
But on running dockerd& the daemon fails to start with the message "Devices cgroup isn't mounted."
How can I use qemu to launch docker and subsequently the hello-world image without Internet access?

I am a beginner at Docker. I need to create two containers for mongo and mongo-express. But, I'm getting an error as error during connect: This error may indicate that the docker daemon is not running.
Then I tried below steps:
I run the cmd as administrator. Then I run the command "C:\Program Files\Docker\Docker\DockerCli.exe" -SwitchDaemon. It didn't work for me. then I tried with 'C:\Program Files\Docker\Docker\DockerCli.exe' -SwitchDaemon way. Then I enabled hypervisor also. Still, I am getting the same error. When I ran the docker version command in cmd I received the below-mentioned outputs:
Then after I tried with cd "C:\Program Files\Docker\Docker" and ./DockerCli.exe -SwitchDaemon separately.
docker info command gives below mentioned error:

Did you install the Docker Desktop on your Windows PC? If not please install it and Run it. If you already installed it, please run it first!
Then you can see whether the docker engine is starting or not!
After the docker engine started check whether this error is still there. Most probably error will fix after doing that!
If the docker engine is not started, please uninstall docker and delete everything from Registry.
Press Win+R and %appdata%\Docker to go and delete all the files.
Then reinstall the docker, if better you can install the docker desktop. Because with the docker desktop, the docker provides a whole bundle with it! Then you will be able to install the docker for windows smoothly.
Because this error usually getting when the docker engine is not started. Also, this may happen missing Linux kernel on windows. Both issues will address with the correct installation of the Docker Desktop.
You can check whether you have a docker Linux subsystem running on your windows pc by running the following command on cmd,
wsl -l
If you get a result like this,
C:\Users\gayan>wsl -l
Windows Subsystem for Linux Distributions:
docker-desktop-data (Default)
docker-desktop
Then you are okay and ready to go.
If not, please try to uninstall and install the docker desktop
Make sure you delete the previous registry, To do that press Win+R and type Regedit Then go to HKEY_LOCAL_MACHINE -> SOFTWARE -> Docker Inc and delete that folder.
If still you are getting the same error, try to troubleshoot the docker desktop. you can refer to the docker documentation.
My docker build cmd is failing to create an image using Dockerfile. It shows this error
here is the screenshot of the error
Check if you can access the site on the host machine.
Check your docker networking, for a docker VM, it is usually a bridge network by default.
Check if you need to add the repository to YUM.
I come across this error when running an image on nvidia-docker. This image used to run well, but now it fails. The change in the device I'm made: cloned docker/compose, then removed docker/compose.
I manage to run nvidia-docker hello-world, but this does not use Nvidia drivers.
I replaced XXX instead of the full path.
running command:
nvidia-docker run --name my_test arg1 bash

docker: Error response from daemon: create nvidia_driver_410.48: found reference to volume 'nvidia_driver_410.48' in driver 'nvidia-docker', but got an error while checking the driver: error while checking if volume "nvidia_driver_410.48" exists in driver "nvidia-docker": Post http://XXXdocker%2Fplugins%2Fnvidia-docker.sock/VolumeDriver.Get: dial unix XXX/docker/plugins/nvidia-docker.sock: connect: connection refused: volume name must be unique.

Try to delete the old containers(including stopped containers), list and delete the nvidia docker volumes. Restart docker daemon if this does not solve the problem.
Else: try to purge/reinstall nvidia-container-toolkit and restart the docker daemon on top of the aforementioned step.
I'm new to using Docker (never used it before) and I'm running into these errors:
I installed the Docker for Windows and following the steps on this
tutorial, but Docker Desktop doesn't load up for me at all.
I tried to run the docker pull hello-world command but I'm getting the error: 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.
How do I fix this? Thanks
New to docker and I'm using Windows 7 SP1. It looks like docker is running fine in my machine as I have tried running hello-world by command docker run hello-world as instructed in the tutorial and got expected result. Now all I'm trying to do is create a docker image for a .net core console app. My app built and ran. but while building docker image by command docker build -t myapp . I get the below error
error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.30/build?buildargs=%7B%7D&cachefrom=%5B%5D&cgroupparent=&cpuperiod=0&c

Below my Dockerfile
FROM microsoft/dotnet:1.1-runtime-nanoserver
WORKDIR /DotNetConsole
COPY /bin/Debug/netcoreapp1.1/publish/ .
ENTRYPOINT ["dotnet", "DotNetConsole.dll"]
I could get around this problem by starting the "Docker QuickStart Terminal" installed with the docker tools, and running the commands for building the docker images from there.
If I used GIT BASH instead of the Docker QuickStart Terminal to execute the commands, I would get this kind of error. So it seems that if the commands are not executed from the Docker terminal itself, these errors show up.
