sh -c "echo deb https://get.docker.com/ubuntu docker main > /etc/apt/sources.list.d/docker.list"
aptitude update; aptitude -y install lxc-docker
or just run below one command:
wget -qO- https://get.docker.com/ | sh
for "docker info" with warning "No swap limit support":
sed -i 's,GRUB_CMDLINE_LINUX_DEFAULT="",GRUB_CMDLINE_LINUX_DEFAULT="cgroup_enable=memory swapaccount=1",g' /etc/default/grub
grub-mkconfig -o /boot/grub/grub.cfg
reboot
CentOS 7.1:
