Add a local docker unit file

Create a file called /media/state/units/docker-local.service that has the following contents:

[Unit]
Description=docker local

[Service]
PermissionsStartOnly=true
ExecStartPre=/usr/bin/systemctl kill docker.service
ExecStart=/usr/bin/docker -d

[Install]
WantedBy=local.target

Enable the local docker

sudo systemctl restart local-enable.service

Have fun!

This was working in earlier versions of CoreOS. I'm returning to CoreOS now after some time away (CoreOS 298.0.0) and this trick no longer works:

core@core-01 ~ $ sudo systemctl restart local-enable.service
Failed to restart local-enable.service: Unit local-enable.service failed to load: No such file or directory.
core@core-01 ~ $

You have to manually enable/start the service now.

systemctl enable docker-local; systemctl start docker-local

This may provide a cleaner option
