I am new to docker, I plug my PI3 to test some stuff and I'm already facing an error, I can't figured that out myself.

So I freshly install raspbian and docker.

That's my install log

Then I try the classic hello-word test

and there is the log

Answer 1

It looks 17.11.0 has the problem.

Could you try to install the old one as below ?

$ sudo apt install docker-ce=17.09.0~ce-0~raspbian

Or wait for the fix.

(2017.12.5)
It looks 2017-11-29-raspbian-stretch has same issue. To avoid upgrading by apt upgrade, Do:
sudo apt-mark hold docker-ce.
And unhold when it fixes.

I can confirm that this solution worked for me. RPi B+ v3 on 12/5/17. – Laevorotatory

Working here. Waiting a notification for the unhold :) – Peradventure

Answer 2

Another solution is to add cgroup_enable=memory cgroup_memory=1 in /boot/cmdline.txt at the end of the line and reboot.

Could you elaborate a bit on the implications of this? What does it do? Are there any negative side effects to be expected? – Schmo

It enables memory control groups, since now it will probably be required to run docker, or at least it's not a bug in docker, it's related to how kernel manages memory, isolates resources. – Bury

This works on a brand new NOOBs based install with stretch. To be just a bit clearer, add these parameters to the end of the existing command line. Do not add them as a new line. – Leghorn

Answer 3

Quick fix: please create a folder and mount using below command:

sudo mkdir /sys/fs/cgroup/systemd
sudo mount -t cgroup -o none,name=systemd cgroup /sys/fs/cgroup/systemd
