py-cfenv
py-cfenv is a tiny utility that simplifies interactions with Cloud Foundry environment variables, modeled after node-cfenv.
Quickstart
from cfenv import AppEnv
env = AppEnv()
env.name # 'test-app'
env.port # 5000
redis = env.get_service(label='redis')
redis.credentials # {'uri': '...', 'password': '...'}
redis.get_url(host='hostname', password='password', port='port') # redis://pass:hostKeys may change based on the service. To see what keys are available for the app's services:
$ cf env my-app
Getting env variables for app my-app in org my-org / space my-space as me@example.com...
OK
