Docker 启动应用，提示： WARNING: Your kernel does not support memory swappiness capabilities, memory swappiness discarded.

每个应用都是这么提示： WARNING: Your kernel does not support memory swappiness capabilities, memory swappiness discarded.

Adjust memory and swap accounting
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.

貌似不可行啊
