本文介绍如何通过编辑GRUB配置文件并启用内存和交换会计功能，来消除在Ubuntu上运行Docker时出现的内核不支持cgroup交换限制的警告。此步骤涉及使用sudo权限编辑/etc/default/grub文件，设置GRUB_CMDLINE_LINUX参数，更新GRUB并重启系统。

When users run Docker, they may see these messages when working with an image:

WARNING: Your kernel does not support cgroup swap limit. WARNING: Your
kernel does not support swap limit capabilities. Limitation discarded.
To prevent these messages, enable memory and swap accounting on your system. To enable these on system using GNU GRUB (GNU GRand Unified Bootloader), do the following.

Log into Ubuntu as a user with sudo privileges.

Edit the /etc/default/grub file.

Set the GRUB_CMDLINE_LINUX value as follows:

GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"
Save and close the file.

Update GRUB.

$ sudo update-grub
Reboot your system.
