Got permission denied while trying to connect to the Docker daemon socket

執行docker指令出現下面的錯誤訊息

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.38/images/load?quiet=0: dial unix /var/run/docker.sock: connect: permission denied

這是因為權限不足，用下面指令加入權限即可

sudo usermod -aG docker $USER
