I am new to Docker and after writing docker version in cmd
I got this error:
error during connect: This error may indicate that the docker daemon is not running.: Get "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/version": open //./pipe/docker_engine: The system cannot find the file specified.
Edit: the OS is Windows.
On Linux you should check the daemon status by systemctl status docker.service, then:
sudo systemctl enable docker.service
sudo systemctl enable docker.socket
sudo systemctl start docker.socket
sudo systemctl start docker.service
On Windows you should check its status by the Windows Service Manager.

I have Microsoft Windows 10 Pro version 10.0.19041 N/A Build 19041 and I follow steps here https://learn.microsoft.com/en-us/windows/wsl/install-win10 to install Ubuntu 20.04 LTS on it using WLS2 , I'm doing so to install docker by following steps here https://docs.docker.com/engine/install/ubuntu/#install-using-the-repository
but when I try to run sudo docker run hello-world it gives me this error docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
See 'docker run --help'. I know that a similar question asked here Cannot connect to the Docker daemon at unix:/var/run/docker.sock. Is the docker daemon running? ,and I try to run systemctl daemon-reload and systemctl start docker but al the solutions does not worked for me it gives me another errors like System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down and Also try to fix it but I can't, So I need your help.
Note : I have already install Docker in windows and It works fine.
I have been solving this problem by following these steps
Purge the Grub package Linux command according this issue https://github.com/microsoft/WSL/issues/4903
Stop Docker Desktop from Windows
Run sudo dockerd which is the daemon service for Docker containers

For Docker run
PS C:\Users\XXXX> docker run hello-world
docker : C:\Program Files\Docker\Docker\Resources\bin\docker.exe: error during connect: Post

I am not getting if docker is installed then why docker images and docker run are not working ?
Make sure the Docker service is runnig.
(1) Go to Services.
(2) Check service Docker for Windows is running.
You can stop/start the service as well using below commands in command prompt.
Net stop com.docker.service
Net start com.docker.service
Refer article : https://success.docker.com/article/docker-for-windows-fails-with-a-daemon-not-running-message
Have you manually started docker after the installation?
Install Docker Desktop on Windows
I couldn't start my ansible server installed in Centos/7 yet the installation works properly, any help plz
[vagrant#ansible-server ~]$ sudo systemctl status ansibled
Unit ansibled.service could not be found.
[vagrant#ansible-server ~]$ sudo systemctl start ansibled
Failed to start ansibled.service: Unit not found.
Ansible is not a Linux system Service. The command you are using is use for any service which is install on the linux. Just use Ansible command to run your playbook or adhoc command.
hello I just installed docker for windows on a windows 10 computer.
docker run -d -p 8787:8787 rocker/rstudio
gives me:
docker: error during connect: Post
http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.35/containers/create: 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. See 'docker run --help'
What I have done so far:
installed https://download.docker.com/win/stable/Docker%20for%20Windows%20Installer.exe
enabled virtualization in the BIOS
made sure that hyper-v is enabled
I working on CentOS7 and I install ceph by manual build
./autogen.sh
./configure
make
make install
and manual deploy by follow this link http://ceph.com/docs/master/install/manual-deployment/
but ceph doesn't exist in directory /etc/rc.d/init.d/
Failed to issue method call: Unit ceph.service failed to load: No such
file or directory
So, I can't start service.
In document of manual deploy it's said I have to use command
sudo /etc/rc.d/init.d/ceph start mon.node1
In CentOS7 use systemd
So, use command sudo systemctl start ceph-osd#0 will work!!!
You can run systemctl status ceph* as a quick way to show any services on the box or systemctl list-units --type=service | grep ceph the service name syntax is ceph-mon#<hostname>.service or ceph-osd#<osd_num>.service
Please run systemctl list-unit-files and you can list all ceph services and you must find OSD number with ceph osd tree and put in this command systemctl status ceph-osd#{OSD_NUM}.target
