Cannot enable cgroup_enable=memory swapaccount=1 on GCE Debian Jessie instance
In order to support Docker memory limits / quotas I'd like to enable the
cgroup_enable=memory swapaccount=1
Linux kernel command line options on my Debian Jessie Google Cloud Compute Engine instances. After adding them to /etc/default/grub
, updating and rebooting I can see the options being active in /proc/cmdline
:
BOOT_IMAGE=/boot/vmlinuz-3.16.0-4-amd64 root=UUID=aeb374a4-1a04-4ed7-adac-d5c57b350575 ro console=ttyS0,38400n8 elevator=noop cgroup_enable=memory swapaccount=1
However, docker info
still complains about them being disabled:
$ docker info
[...]
WARNING: No kernel memory limit support
WARNING: No cpu cfs quota support
WARNING: No cpu cfs period support
[...]
Any ideas? Has the kernel included with the GCE Debian image built without support for these features?
Update /etc/default/grub
and set:
GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"
run update-grub && reboot
Instead of docker info
(which seems to be buggy) use rather lxc-checkconfig
or check-config.sh from Docker (moby) repository:
wget https://raw.githubusercontent.com/moby/moby/master/contrib/check-config.sh && bash check-config.sh
