Docker:设备 cgroup 未安装(Ubuntu 16.04)

Question

我正在尝试在远程网络服务器上的 Ubuntu 16.04 上安装 docker。但是，我收到一个让我非常沮丧的错误。我已经安装了很多次 docker，也在这个操作系统上，但这从未发生过。

我卡在sudo apt-get install -y docker-engine，无法安装docker-engine:

~# systemctl status docker.service

我将 root 添加到组中，还找到了将 GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1" 添加到文件/etc/default/grub 的建议，但该文件不存在!

我也试过 sudo apt-get install cgroupfs-mount 但没有成功:-(

感谢您的帮助!

所以，伙计们。不幸的是，没有解决方案。原因是远程网络服务器的架构，一个托管的虚拟机。 我的供应商告诉我，所有虚拟机在一个环境中都使用相同的内核，因此 dokker 无法访问它。

现在唯一的选择是切换到另一台服务器。
