Question

添加后：

-g /vagrant/lib/docker

我尝试重新启动 dockerd 时出现这些错误：

● docker.service - Docker Application Container Engine
   Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)

以下是systemd：

的配置文件的摘录

[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)

该图表无法在/vagrant上运行。您可以选择任何其他文件夹，它应该工作。问题是因为这与普通文件夹不同，它在主机和VM之间共享和同步。

您可以看到类型为vboxsf。此安装的文件夹的行为方式不同。因此，在此安装的docker卷和docker图表也表现得很奇怪。我不知道究竟有什么不同，但我知道它不起作用。如果有人知道确切的区别，那么请做评论

Dockerd --graph / - data-root似乎不适用于systemd
