SDK not starting

[cgreenhalgh]

On current release (Databox 0.5.2) I just tried starting the SDK as per readme, i.e.

docker run --rm -v /var/run/docker.sock:/var/run/docker.sock --network host -t databoxsystems/databox:0.5.2 /databox sdk -start

and it starts the various containers including databox-sdk (mongo, redis, test server, datasource-mock), but that container exits almost immediately. Log output is:

set port to 8086
dev mode  false
