Neo4j for OpenShift?

Question

NoSQL

Prompt at whom there is an experience how to unroll a subject?

Tried it - github.com/tomasmuller/openshift-neo4jtemplate Have
n't mastered it yet.
In particular, the 8th (what exactly the environment variable should contain, and where to set it, in action_hooks) and the 9th points (here jetty is launched, but on the local machine, as I understand it, what's the point?) Is not clear.

Or tell me where else you can host Neo4j for free?
