在运行Android Studio Cloud后，切换root用户启动docker服务会提示：
Failed to start docker.service: Unit docker.service is masked.
Failed to start docker.service: Unit docker.socket is masked.解决办法
取消 mask 状态
systemctl unmask docker.service
systemctl unmask docker.socket再次运行docker还是报错:

systemctl unmask containerd.service启动docker
启动正常无报错
systemctl start docker
