py-cfenv

py-cfenv is a tiny utility that simplifies interactions with Cloud Foundry environment variables, modeled after node-cfenv.

Quickstart

fromcfenvimportAppEnvenv=AppEnv()
env.name# 'test-app'env.port# 5000redis=env.get_service(label='redis')
redis.credentials# {'uri': '...', 'password': '...'}redis.get_url(host='hostname', password='password', port='port') # redis://pass:host

Keys may change based on the service. To see what keys are available for the app's services:

$ cf env my-app
Getting env variables forapp my-appin org my-org / space my-space as me@example.com...
OK
