systemctl docker.service设置未生效

Question

我正在Ubuntu 18.04.1上运行Docker 18.03.5

环境

$ docker version

Docker.Service

使用sudo systemctl edit docker.service，将其保存在我的override.conf中

# /etc/systemd/system/docker.service.d/override.conf
[Service]
#ExecStart=/usr/bin/docker daemom -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock
ExecStart=
ExecStart=/usr/bin/dockerd --group beijing -H unix:///var/run/docker.sock

Docker套接字错误权限

运行后

$ sudo systemctl daemon-reload
$ sudo systemctl restart docker

我仍然看到Docker套接字默认为 docker 组，而不是北京组

是什么导致docker.service设置不生效？
