I'm trying to deploy a flaskapp with docker, so I have two containers, one for my flaskapp and another for redis. I've setup a network and executed both within it. When accessing my flaskapp the following error occurs:
ConnectionError: Error 99 connecting to localhost:6379. Cannot assign requested address.
This is happening because I'm using redis as cache for flask-session and I'm hosting redis at a container called exampleredis.
My question is: how can I setup redis host to be exampleredis in Flask?
I have the following config file:
class DevConfig(Config):
REDIS_HOST = 'exampleredis'
SESSION_TYPE = 'redis'
JSONIFY_PRETTYPRINT_REGULAR = False
JSON_SORT_KEYS = False
BCRYPT_LOG_ROUNDS = 15
DEBUG = True
According to the document of flask-session, this should probably work:
import redis
class DevConfig(Config):
SESSION_REDIS = redis.from_url('redis://exampleredis:6379')
SESSION_TYPE = 'redis'
...
