I have installed docker client on Windows Subsystem for Linux (WSL) on Windows 10.0.17763 Home.
When I run
sudo docker ps
I got:
Cannot connect to the Docker daemon at tcp://localhost:2375. Is the
docker daemon running?
and after removing docker environment variables (unset DOCKER_HOST , unset DOCKER_TLS_VERIFY , unset DOCKER_TLS_PATH), I still have the same issue with docker daemon:
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is
the docker daemon running?
When I try to start docker daemon sudo systemctl start docker I am getting:
Failed to connect to bus: No such file or directory
docker version is 19.03.4
docker compose version is 1.24.1
Also restarting LxssManager win service will not help.
What should I do?
WSL is no real Linux Kernel which is why nothing, also running the Windows Subsystem for Linux as administrator by right clicking from start menu and running sudo service docker start does not work.
There is a new version, WSL 2 which is supposed to solve the docker issue but I did not try it our so far: https://docs.docker.com/docker-for-windows/wsl-tech-preview/

I am struggling with docker in order to run it. I got Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? error. thereafter I tried several things but it did not work.

Interacting with snapd is not yet supported on Windows Subsystem for Linux.
This command has been left available for documentation purposes only.
I'm using ubuntu 18.04 app in windows system. what should I do?
Seems like WSL cannot connect to the docker daemon running through Docker for Windows, probably because it is not exposed or is not running.
WSL1
In case you are using WSL 1, you can expose the docker daemon through this option in Docker for Windows:
I recommend this article for a detailed guide.
I would highly recommend running docker within WSL 2 instead, since it provides faster boot times and allows docker to use CPU/RAM dynamically instead of you having to preallocate it.
WSL2
In case you are using WSL 2, you will have to enable the WSL 2 back-end for docker through Docker for Windows. The docker team has an extensive guide on this here.
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

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.

I have installed minikube and started it with it's default virtual machine so basically started the minikube with minikube start. In minikube vm which i have accessed through minikube ssh i am trying to build my dockerfile after mounting the local file system but it's showing error Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
I checked the ActiveState of docker through systemctl show --property ActiveState docker and it's showing failed but the docker version is showing me all the normal details like version built etc.
This is the statement that i am trying to execute : $ sudo docker build --file=Dockerfile --tag=demo-backend:latest --rm=true .
Should i install docker seperatley and if not how should access docker in VM which is already present in my system
It looks like somehow docker has not started properly.
Please try to execute sudo systemctl start docker and let me know if that was the issue.
EDIT:
Adding more info from the comments in order to supplement the answer:
I had to set the docker environment variable to local instance of
docker running in minikube through this command: eval $(minikube
docker-env) and then restart the docker and all of this has to done in
the same shell in which i aim to access the docker otherwise it does
not works. this made me acces the docker from minikube – rehan
On a Ubuntu 14.04 server instance I uninstalled the previous Docker version and installed docker-ce.
Now, when I'm trying to issue for example docker ps, I get
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
Running sudo docker ps does not fix it.
Restarting the Server using sudo service docker restart neither does fix it.
Current user is already in docker group.
Solved it:
/var/log/upstart/docker.log
Did contain this entry:
Error starting daemon: error initializing graphdriver: /var/lib/docker contains several valid graphdrivers: devicemapper, aufs; Please cleanup or explicitly choose storage driver (-s <DRIVER>)
I deleted /var/lib/docker/devicemapper and everything went back to normal.
I am running Ubuntu 14 in codeanywhere.com, and I'm getting "Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?" error when I try to build the docker image.
Also, when I try to stop docker, I'm getting "stop: Unknown instance:", looks like Docker never got started.
How should I fix this problem?

I've tried installing docker on an ubuntu-14 machine running on codeanywhere.com right now using this guide, and when the installation process was finished I found this error in /var/log/upstart/docker.log -
time="2018-02-10T03:09:22.148778137-05:00" level=fatal msg="Your Linux kernel version 2.6.32-042stab112.15 is not supported for running docker. Please upgrade your kernel to 3.10.0 or newer."
Even if upgrading the kernel is somehow possible, I don't think codeanywhere.com is the right place to install docker on, as the env itself is probably a docker container. If you're adamant about doing this, perhaps you should contact them and check for the best course of action for your needs.
