Dockerd –graph / – data-root似乎不能与systemd一起使用
添加完后：
-g /vagrant/lib/docker 我尝试重新启动dockerd时遇到这些错误：
● docker.service - Docker Application Container Engine Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Thu 2017-08-03 21:20:50 UTC; 1s ago Docs: https://docs.docker.com Process: 6495 ExecStart=/usr/bin/dockerd -g /vagrant/lib/docker -H fd:// (code=exited, status=1/FAILURE) Main PID: 6495 (code=exited, status=1/FAILURE) CPU: 61ms Aug 03 21:20:50 badger systemd[1]: docker.service: Main process exited, code=exited, status=1/FAILURE Aug 03 21:20:50 badger systemd[1]: Failed to start Docker Application Container Engine.

以下是systemd的configuration文件的摘录：
[Service] Type=notify # the default is not to use systemd for cgroups because the delegate issues still # exists and systemd currently does not support the cgroup feature set required # for containers run by docker ExecStart=/usr/bin/dockerd -g /vagrant/lib/docker -H fd://

vagrant@vagrant:~$ mount | grep vagrant /dev/mapper/vagrant--vg-root on / type ext4 (rw,relatime,errors=remount-ro,data=ordered) /dev/mapper/vagrant--vg-root on /var/lib/docker/aufs type ext4 (rw,relatime,errors=remount-ro,data=ordered) vagrant on /vagrant type vboxsf (rw,nodev,relatime)
该图不会在/vagrant 。 你可以select任何其他文件夹，它应该工作。 问题是因为这不同于普通文件夹，它在主机和虚拟机之间共享和同步。
正如你可以看到types为vboxsf。 这个挂载文件夹的行为不一样。 因此，装载在这上面的docker和docker图也performance怪异。 我不知道什么是不同的，但我知道这是行不通的。 如果有人知道确切的差异，然后做评论
