When i try to open Docker Desktop app i see that in systemd.
And Docker Desktop doesn't start too.
$ /usr/lib/systemd/user/docker-desktop.service:8: Failed to parse service type, ignoring: exec
$ graphical-session.target: Unit not needed anymore. Stopping.

I'm getting the following error when I try to run test container in my java app from the IDE:
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
however docker desktop is running.
Also I am getting the same error when I run the testcontainers/ryuk image directly from docker desktop by clicking the run button in the images panel.
But the container runs when I use the following command in the terminal:
docker run -i --mount type=bind,source=/var/run/docker.sock,destination=/var/run/docker.sock testcontainers/ryuk:0.3.4
EDIT:
the test container works when I installed docker engine cli and use it as the active context but it's a hassle switching. It seems the default bind being used is cli.
EDIT2:
I've uninstalled and purged every docker installation and reinstalled only docker desktop and it's still the same, on a windows machine it's working properly though.
[x] I have tried with the latest version of my channel (Stable or Edge)

Expected behavior
sudo service docker command ran on wsl2 (4.19.121-microsoft-standard) should print service status
Actual behavior
sudo service docker command prints docker: unrecognized service
Information
Windows Version: 20161.1000, Windows Feature Experience Pack 120.16201.0.0
Docker Desktop Version: 2.3.0.3 (45519)
Are you running inside a virtualized Windows e.g. on a cloud server or on a mac VM: nope
I followed instructions in docker documentation page for wsl so docker can installed to my windows, and checked the command docker run -d -p 80:80 docker/getting-started on ubuntu running successfully, but the service command won't work as described above.
Steps to reproduce the behavior
follow the instructions in here
sudo service docker on wsl2 ubuntu
I am new to Docker. I'm trying to work with it on windows.
I have Windows 10 Family so I installed Linux Bash Shell.
When I run this command:
$ docker run hello-world
I get :
docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
And when I run
$ systemctl status docker
I get
System has not been booted with systemd as init system (PID 1). Can't operate
For anyone using WSL2 and seeing an identical error message, look at https://github.com/MicrosoftDocs/WSL/issues/457#issuecomment-511495846
Powershell

Hello from Docker!
This message shows that your installation appears to be working correctly.
It seems like you wont be able to use docker in Windows 10 family, since docker Desktop requires specific Windows version, as said in official documentation.
System Requirements
Windows 10 64-bit: Pro, Enterprise, or Education (Build 15063 or later).
What you can try is to run linux-based virtual machine on you Windows host, and run docker inside of it. But even if you succeeded, you will lose all advantages of the docker in resources consumption.
Just run the Docker Daemon with.
sudo dockerd &
The sudo make it run as super user.
Dockerd is DOCKERDaemon
The single & at the end just make it run in the background.
The issue here is that from the error message, it states that you are using WSL (Windows Sub-system for Linux Version 1), this version did not have Docker support as it is not a full Linux kernel, but an translation layer between a Linux user-space and then translated to Windows Kernel commands.
Running the wsl --list -v command will show you the version you are using:
You can install WSL version 2, which has a Microsoft provided full Linux Kernel running using Hyper-V infrastructure (but not full Hyper-V). This way it runs on Windows Home, Education, and Professional. And here you can run a Linux Instance and the install Docker.
Windows Subsystem for Linux Installation Guide
After starting a command prompt, I normally start with login in to openshift with this command:
$ oc login https://api.starter-us-west-1.openshift.com
--token=
Works fine. Up till now I then connected to the docker registry of Openshift with the command:
$ docker login -u myOpenShiftName -p registry.starter-us-west-1.openshift.com (or :443)
Now I get this error (partly translated):
Warning: failed to get default registry endpoint from daemon (error
during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.37/info:
open //./pipe/docker_engine: The system cannot find the specified
file. 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.). Using system default:
https://index.docker.io/v1/
Do I need a local docker running?
UPDATE/ANSWER: yes. On windows10 home start e.g. DockerQuickstartTerminal.
At another computer I had a similar error on Windows 10 pro with Docker. The service was started, but after I had started "Docker for Windows" the error disappeared.
My environment is Win10 home, virtual box + extension + docker toolbox.
The docker command cannot work without its local Docker daemon process running.
If you want to be able to work with OCI/Docker images and not need docker and the daemon, for some things you can use a tool like Skopeo.
https://github.com/containers/skopeo
There are also tools for building OCI container images which aren't dependent on docker.
I am running docker commands in the docker quick start terminal. I need to run those commands in my windows terminal. When I check the version of docker, It shows correctly but when I run docker ps or other docker commands. It shows like :
C:\Users\rajasekar.sambandam>docker ps
error during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.29/containers
/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.
On Windows, docker runs in the background in an linux VM. The quick start terminal delegates all the calls to the VM, and thats why the docker commands work.
When running from a normal terminal, run the command:
eval $(docker-machine env default)
This command will connect the current terminal to the backgound machine.
