To create the redis instance within your application

from flask import Flask
from flask.ext.redis import FlaskRedis
app = Flask(__name__)
redis_store = FlaskRedis(app)

or

from flask import Flask
from flask.ext.redis import FlaskRedis
redis_store = FlaskRedis()
def create_app():
    app = Flask(__name__)
    redis_store.init_app(app)
    return app

USE

from ..configs import redis_store
@app.route('/')
def index():
    potato = redis_store.get('potato', 'None')
    if potato is None:
        potato = 'potato'
        redis_store.set('potato',potato)
    return potato
