how to get permission
docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/create": dial unix /var/run/docker.sock: connect: permission denied.
Solution 1:
You have to add your user to the docker group by
sudo usermod -a -G docker $USER
then reboot and retry running Docker-related command.
