Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.39/images/json: dial unix /var/run/docker.sock: connect: permission denied

 

Solution:

The error message tells you that your current user can’t access the docker engine, because you’re lacking permissions to access the unix socket to communicate with the engine.

As a temporary solution, you can use

sudo

to run the failed command as root.

However, it is recommended to fix the issue by adding the current user to the 

docker group:

Run this command in your favorite shell and then completely log out of your account and log back in (if in doubt, reboot!):

  • sudo usermod -a -G docker $USER

After doing that, you should be able to run the command without any issues. Run

docker run hello-world

as a normal user in order to check if it works. Reboot if the issue still persists.

Logging out and logging back in is required because the group change will not have an effect unless your session is closed.
