error starting docker daemon on ubuntu 14.04 (Devices cgroup isn't mounted)
I resolved this issue by starting the docker deamon manually using:
sudo service docker start
Note: Looks like this issue was only present in Ubuntu 14.04 and earlier. The newer Ubuntu versions don't need this.
Try 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-grubReboot your system.
Some folks have reported restarting the docker daemon works:
sudo systemctl restart dockerAs noted above the newer docker documentation doesn't refer to this in the new Docker versions.
Update
This works for some folks on Ubuntu 14.04 or earlier:
sudo apt-get install cgroup-lite
maybe need packages:
apt-get install aufs-toolsapt-get install cgroup-lite
