More Neo4j than you can shake a cat at

manage multiple ephemeral neo4j containers

tamarind is a system that manages Neo4j databases by provisioning Docker container resources for you. The user-facing API provides access to a dictionary-like lookup for your databases, and allows you to start and stop database servers on the fly.

Installation

Install from PyPI using pip:

pip3 install tamarind

You will need Docker already installed if you intend to use the Docker provisioning service. You can install Docker with the script from https://get.docker.com/.

Usage

Creating a new db

from tamarind import Neo4jDockerProvisioner

N = Neo4jDockerProvisioner()

N.start("MyDatabase")

Now you can access this graph database through py2neo:

>>> N["MyDatabase"]
<py2neo.Graph>

The object returned is a py2neo.database.Graph object:

>>> N["MyDatabase"].run("MATCH (a:Person) RETURN a.name, a.born LIMIT 4").data()
[{'a.born': 1964, 'a.name': 'Keanu Reeves'},
 {'a.born': 1967, 'a.name': 'Carrie-Anne Moss'},
 {'a.born': 1961, 'a.name': 'Laurence Fishburne'},
 {'a.born': 1960, 'a.name': 'Hugo Weaving'}]

List all

>>> N.ps().keys()
['MyDatabase', 'OldDatabase']

Stop a service

>>> N.stop("OldDatabase")
>>> N.ps().keys()
['MyDatabase']

Custom Provisioners

If you provision Neo4j instances via resources other than Docker (e.g. via AWS EC2 AMIs), you can extend the Neo4jProvisioner class with start and ps function calls (stop is an optional implementation in Tamarind).
