Public bug reported:

Hello everybody,

this is my first bug report, so I apologize for any mistakes.

I'm trying to install docker with swap support, but cgroups swap support
is missing. It works on ubuntu 17.10, but it breaks on ubuntu 18.04

Was cgroup swap support removed from default kernel in ubuntu 18.04?
Should I recompile the kernel to enable it?


This is what check configs report:

root@proxima:~# wget
https://raw.githubusercontent.com/moby/moby/master/contrib/check-
config.sh && bash check-config.sh


- CONFIG_MEMCG_SWAP_ENABLED: missing
    (cgroup swap accounting is currently not enabled, you can enable it by 
setting boot option "swapaccount=1")


this is my /etc/default/grub

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="console=tty1 console=ttyS0 cgroup_enable=memory 
swapaccount=1"
GRUB_CMDLINE_LINUX=""
