我该如何纠正这个问题？
答案1
看起来您当前的内核不支持 Docker 所需的 Cgroups 功能。您使用的是 Debian 吗？无论如何，这些警告表明无法对 Docker 容器应用内存、CPU 和交换限制。如果您想要/需要它们，您应该更新内核。
答案2
在 Xenial 上也遇到了同样的问题，我正准备根据 docker 的需求重新编译内核，但没有发现当前配置中任何开关被停用，正如它声称的那样。结果：一旦我删除（--purge）所有 docker 数据包（包括 cgroupfs-mount 和 aufs-tools），并再次安装完全相同版本的 docker，它就可以正常工作了。猜测这是由某些所需数据包的详细信息中的某些内容引起的。够奇怪的了。
