Cannot connect to the Docker daemon at unix:/var/run/docker.sock. Is the docker daemon running?
Solution 1
You can try out this:
systemctl start docker
It worked fine for me.
P.S.: after if there is commands that you can't do without sudo, try this:
gpasswd -a $USER docker
Solution 2
Just Run
sudo dockerd
dockerd is the daemon service for docker containers, because it is not running in background we're not able to take any actions related to the service, which needs be restarted.
Solution 3
You can get this error if docker doesn't shut down cleanly. The following answer is for the docker snap package.
Run snap logs docker
and look for the following:
Error starting daemon: pid file found, ensure docker is not running or delete /var/snap/docker/179/run/docker.pid
Deleting that file and restarting docker worked for me.
rm /var/snap/docker/<your-version-number>/run/docker.pid
snap stop docker
snap start docker
Make sure to replace <your-version-number>
with the appropriate version number.
Solution 4
Easy way to fix this issue, try this
sudo su
systemctl start docker
systemctl enable docker
systemctl restart docker
Solution 5
I just hit this after doing a fresh install of DOCKER from the main docs. The problem for me was that immediately after the install, the service is not running.
These commands will help you to make sure docker is up and running for your run command to find it:
$ sudo service --status-all
$ sudo service docker start
$ sudo service docker start

I have applied every solution available on internet but still I cannot run Docker.
I want to use Scrapy Splash on my server.
Here is
history
of commands I ran.docker run -p 8050:8050 scrapinghub/splash sudo docker run -p 8050:8050 scrapinghub/splash sudo usermod -aG docker $(whoami) sudo docker run -p 8050:8050 scrapinghub/splash newgrp docker sudo docker run -p 8050:8050 scrapinghub/splash reboot sudo docker run -p 8050:8050 scrapinghub/splash docker run -p 8050:8050 scrapinghub/splash
You can see I tried to restart my server as well, but it didnt help.
