cfenv

0.5.3 verified Mon Apr 27 auth: no python

Python wrapper for Cloud Foundry environments, providing easy access to VCAP_SERVICES and VCAP_APPLICATION environment variables. Current version: 0.5.3, updates infrequent.

pip install cfenv

Common errors

error AttributeError: 'CfEnv' object has no attribute 'name' ↓

cause Usually missing or malformed VCAP_APPLICATION environment variable.

fix

Ensure you are running inside Cloud Foundry or set VCAP_APPLICATION manually for testing.

error ImportError: No module named cfenv ↓

cause Library not installed.

fix

Run: pip install cfenv

Warnings

gotcha CfEnv() expects VCAP_APPLICATION to be set; throws AttributeError if not in a Cloud Foundry environment. ↓

fix Wrap in try-except or check the environment first.

gotcha Accessing service credentials via cfenv.get_credential() may return None if key missing. ↓

fix Use .get() with default or check key existence.

deprecated Methods like .get_service() may be renamed; prefer .get_service(name=...) over positional args. ↓

fix Use keyword arguments: cfenv.get_service(name='my-service')
