redisconfig

Simple, robust Redis configuration for Python

Installation

pip install redisconfig

Basic Usage

>>> import redisconfig

>>> config = redisconfig.RedisConfig()
RedisConfig(host='127.0.0.1', port=6379, db=0, ssl=False, password=None)

>>> config.host
'127.0.0.1'

>>> config.url()
'redis://127.0.0.1:6379/0'

>>> config.connection()
Redis<ConnectionPool<Connection<host=127.0.0.1,port=6379,db=0>>>

REDIS_URL Environment Variable

In many cases the Redis connection URL is stored in the REDIS_URL environment variable. redisconfig will use that value as a default for several operations, such as the module-level config() and connection() methods. With an environment variable of REDIS_URL=rediss://noop:badpassword@10.0.0.1/2:

>>> redisconfig.config()
RedisConfig(host='10.0.0.1', port=6379, db=2, ssl=True, password='badpassword')

>>> redisconfig.connection()
Redis<ConnectionPool<SSLConnection<host=10.0.0.1,port=6379,db=2>>>

Update Configuration Values

You can update values directly like config.db = 5 but sometimes you want to change values without changing the underlying configuration. The url() and replace() methods on RedisConfig allow you to make new urls or configs without changing the original values.

Create a new URL:

>>> config = redisconfig.RedisConfig()
>>> config.url()
'redis://127.0.0.1:6379/0'

>>> config.url(db=2)
'redis://127.0.0.1:6379/2'

Create a new RedisConfig instance:

>>> config.replace(db='10.0.0.1')
RedisConfig(host='10.0.0.1', port=6379, db=0, ssl=False, password=None)

Developing

The following things are needed to use this repository:

Once you have the prerequisites installed and have cloned the repository you can ready your development environment with poetry install -E dev. You should see output similar to:

$ poetry install -E dev
Creating virtualenv redisconfig in /tmp/redisconfig/.venv
Installing dependencies from lock file

...
