Docker on windows error related to daemon - docker

I am trying to install Docker Tools on Windows 7 laptop, installed Docker using Windows Docker Tools.
When I run docker run hello-world I get the below error. I have already removed the VM, and recreated it. Also, I am using a VPN.
Please let me know what steps should I try next.
C:\Program Files\Docker Toolbox\docker.exe: error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.35/containers/create: open //./pipe/docker_engine: The system cannot find the fi 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. See 'C:\Program Files\Docker Toolbox\docker.exe run --help'.

Try restarting the docker service using below on cmd-prompt:
Net stop com.docker.service
Net start com.docker.service
or restart the Docker for Windows service through the Windows GUI by right clicking the service and choosing restart
Have a look at this article on success.docker.com

Building a docker image on wsl

I got a new machine and am now using wsl for the first time instead of just ubuntu. I am trying to rebuild one of my projects, but I am unable to build the docker image.
When running docker-compose build I get the error:
ERROR: Couldn't connect to Docker daemon at http+docker://localhost - is it running?
If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
I have tried running:
systemctl start docker
But then I get the error:
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down
Can anyone tell me what im doing wrong , please and thank you.
From WSL you actually want to use Docker from the Windows host:
Install Docker Desktop for Windows
Go to the settings > Resources > WSL Integration and flip the switch for the Distros where you want Docker enabled.
You should now be able to run docker -v in your WSL commandline and get an output of the Docker version

Run windows container on docker toolbox?

I am trying to run microsoft/iis:latest image on my docker toolbox set-up in my Windows 10 Home.
As expected, with the containers running on a virtual linux VM, i get the below message.
$ docker run -it microsoft/iis
Unable to find image 'microsoft/iis:latest' locally
latest: Pulling from microsoft/iis
C:\Program Files\Docker Toolbox\docker.exe: no matching manifest for linux/amd64 in the manifest list entries.
See 'C:\Program Files\Docker Toolbox\docker.exe run --help'.
Is there a way i can run such containers on toolbox, without using 'Docker for Windows' set-up?
Thanks.
Nope, you cannot run Windows containers in Windows Home. Windows containers run directly in the OS without the intervention of Docker Desktop. Docker Desktop is only a convenient interface in this case.
You can install in Virtualbox Microsoft Hyper-V Server with is free and there (I think) you can run Windows Containers.

Openshift (oc) login to registry keeps on failing - how to start the Docker daemon?

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.

There are also tools for building OCI container images which aren't dependent on docker.

how to run docker commands in my windows command prompt?

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.

docker create service unavailable

I am behind a corporate firewall, running on Windows 7. I believe that I have gotten past any proxy issues (at least as far as accessing the container for which I'm trying to install.)
At this point I'm trying to execute docker's run command which 'acquires' the tensorflow package an installs it on my system.
$ docker run -it -p 8888:8888 gcr.io/tensorflow/tensorflow
C:\Program Files\Docker Toolbox\docker.exe: An error occurred trying to connect:
Post https://192.168.99.100:2376/v1.23/containers/create: Service Unavailable.
See 'C:\Program Files\Docker Toolbox\docker.exe run --help'.
I'm new to docker, (obviously) but I see that the 192.168.99.100 default docker container exists and is running.
I do see documentation regarding the 'create' service endpoint. I'm at a dead end. Any help is appreciated.

when you type docker command docker client try to connect with your local docker service. And in linux world you need a superuser privileges to connect client and service.
I don`t run docker on windows, but may be you need run docker as Administrator. like linux
sudo docker run ...
