Migrating Docker Storage....

Stop Docker Service

service docker stop

Copy all the things!

mkdir /pods/docker_data
rsync -avh --progress /var/lib/docker/ /pods/docker_data/

Edit /etc/default/docker to look like this*:

# Docker Upstart and SysVinit configuration file

DOCKER_OPTS="-H=tcp://0.0.0.0:1337 --api-enable-cors -g /pods/docker_data"

*Heads up! If you're doing this on a hypervisor that is touched by the automation in rdocker-cli then you'll need to edit this line in labsalt to include your salt id.

Reboot for good measure

reboot

Once you're back in, do a docker info to make sure the storage directory is pointed to the right place.
