Swap limit support allows you to limit the swap the container uses, see https://docs.docker.com/engine/admin/resource_constraints
According to https://docs.docker.com/engine/installation/linux/linux-postinstall/#your-kernel-does-not-support-cgroup-swap-limit-capabilities :
You can enable these capabilities on Ubuntu or Debian by following
these instructions. Memory and swap accounting incur an overhead of
about 1% of the total available memory and a 10% overall performance
degradation, even if Docker is not running.
1) Log into the Ubuntu or Debian host as a user with sudo privileges.
2) Edit the
/etc/default/grub
file. Add or edit theGRUB_CMDLINE_LINUX
line to add the following two key-value pairs:GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"
3) Update GRUB.
$ sudo update-grub

Well for me it's been like this:
edit the file /etc/default/grub.d/50-cloudimg-settings.cfg and edit the line to GRUB_CMDLINE_LINUX_DEFAULT="console=ttyS0 cgroup_enable=memory swapaccount=1"
sudo nano /etc/default/grub.d/50-cloudimg-settings.cfg
update grup
sudo update-grub
reboot
sudo reboot
