Flask-Zookeeper
The Flask-Zookeeper extension provides support to Zookeeper clusters.
Quickstart
First, install cdumay-rest-client using pip:
pip install flask-zookeeper
Flask-Zookeeper depends, and will install for you, recent versions of Flask and Kazzo. Flask-Zookeeper is compatible with and tested on Python 2.7, 3.4 and 3.5.
Next, add a FlaskZookeeperClient instance to your code:
from flask import Flask
from flask_zookeeper import FlaskZookeeperClient
app = Flask(__name__)
fzc = FlaskZookeeperClient(app)You can take a look at tests/test_base.py for more complete example.
You can also take a look at tests/test_blueprint.py for an example using Flask’s application factories and blueprints.

Flask-Zookeeper uses additional variables which can be set in the app.config:
