命令docker run hello-world给我这个错误： System error: write /dev/cgroup/docker/<hash>/cgroup.procs: no space left on device
这是一个Debian Wheezy，来自backports的3.16内核。 （以前从挤压升级）
/ dev作为/ dev / dev / dev / dev udev on /dev type devtmpfs (rw,relatime,size=10240k,nr_inodes=1019797,mode=755)的10MB udev on /dev type devtmpfs (rw,relatime,size=10240k,nr_inodes=1019797,mode=755) devtmpfs挂载udev on /dev type devtmpfs (rw,relatime,size=10240k,nr_inodes=1019797,mode=755)
docker工有一个configuration选项，我需要改变？

将cgroup_enable = memory swapaccount = 1添加到您的grub并重新启动操作系统。
$ sudo vim / etc / default / grub
GRUB_CMDLINE_LINUX =“cgroup_enable =内存swapaccount = 1”
$ sudo update-grub
$ sudo重启
参考
“\ df / dev / cgroup /”是什么意思？ 难道是文件系统是“虚拟服务器”？ 在这种情况下，您可能会遇到vserver和docker之间的不兼容问题（使用相同的基础技术）。
在我的系统上，\ df不会显示它，但只有明确地提供df的path才会显示。
它也会显示在“cat / proc / mounts”中。
