Ubuntu 16調整docker數據路徑：docker
注：docker默認數據路徑爲/var/lib/docker，佔用的系統盤空間，咱們須要改成/space/docker，遷到數據盤下。ide
先按正常安裝dockerspa
systemctl stop docker
rsync -av --progress /var/lib/docker /space/
vi /etc/systemd/system/multi-user.target.wants/docker.service
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock --data-root=/space/dockerrest
:wqget
systemctl daemon-reload
systemctl start docker
docker images （確認原來的image都在）
rm -rf /var/lib/docker
systemctl restart docker
