Cloud Media Service Configuration Manager

Overview

Build a Python utility that manages configuration for a cloud-based media service. The utility must load credentials from environment variables and provide a simple way to verify the configuration is set up correctly.

Requirements

Create a module config_manager.py that implements the following functionality:

1. Configuration Loading

• Load configuration from a URL-formatted environment variable
• Support loading cloud name, API key, and API secret from the environment
• Allow programmatic configuration setup (setting values via code)

2. Configuration Retrieval

• Provide a way to retrieve the current configuration settings
• Return the cloud name, API key, and API secret values

3. Configuration Validation

• Check that all required parameters are set (cloud name, API key, API secret)
• Raise a clear error if any required configuration is missing

Implementation Notes

• Focus on configuration management only
• The configuration should be retrievable for verification purposes
• Keep the implementation straightforward

Test Cases { .test-cases }

Test Case 1: Load configuration from environment variable { .test-case @test }

File: test_config.py { .test-file }

Setup:

import os
os.environ['CLOUDINARY_URL'] = 'cloudinary://123456789012345:abcdefghijklmnopqrstuvwxyz123456@test-cloud'

Expected behavior:

• Configuration manager successfully loads cloud name, API key, and API secret
• Cloud name should be 'test-cloud'
• API key should be '123456789012345'
• API secret should be 'abcdefghijklmnopqrstuvwxyz123456'

Test Case 2: Missing configuration raises error { .test-case @test }

File: test_config.py { .test-file }

Setup:

import os
# Clear any existing Cloudinary configuration
for key in list(os.environ.keys()):
    if key.startswith('CLOUDINARY'):
        del os.environ[key]

Expected behavior:

• Attempting to validate configuration without proper setup should raise an exception
• The exception should indicate missing required configuration

Test Case 3: Manual configuration setup { .test-case @test }

File: test_config.py { .test-file }

Setup:

# No environment variables set

Expected behavior:

• Configuration manager allows setting cloud name, API key, and API secret programmatically
• Configuration can be retrieved to verify the values were set correctly
• All three parameters (cloud_name, api_key, api_secret) should be accessible
