Multi-Environment Configuration Manager

A utility that manages application credentials across different deployment environments using secure credential injection.

Capabilities

Load credentials from dictionary

• When given a dictionary with keys "API_KEY" and "SECRET_TOKEN", the function creates a credential configuration that can be used by remote functions @test
• When given an empty dictionary, the function creates a credential configuration with no values @test

Load credentials from environment variables

• When environment variables "DATABASE_URL" and "API_ENDPOINT" are set locally, the function copies them to make them available in remote execution @test

Load credentials from configuration file

• When given a path to a .env file containing "SERVICE_KEY=abc123" and "AUTH_TOKEN=xyz789", the function loads these credentials for remote use @test

Execute remote function with injected credentials

• A remote function decorated with credential injection successfully accesses "API_KEY" from its environment variables when credentials are provided from a dictionary @test
