How to fix docker ‘Got permission denied while trying to connect to the Docker daemon socket’
Problem:

You are running a command like docker ps but you get this error message:

    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/containers/json: dial unix /var/run/docker.sock: connect: permission denied

Solution:

As a quick fix, running the command as root using sudo (e.g. sudo docker ps) will solve the issue temporarily.

The issue here is that the user you’re running the command as is not a member of the docker group. In order to add it to the docker group, run

    sudo usermod -a -G docker $USER

After running that command, you need to logout and log back in to your computer (or terminate your SSH session and re-connect in case you are logged in using SSH) – else, the group change does not take effect.
