Configuration management

[StefanSchade]

Need for configuration

• adapters (data base connections, web server urls etc.)
• entry point Dependency Injection (which adapters to use)
• everywhere (log levels)

Configuration via a file or via environment variables (the later is important for production scenarios)

[StefanSchade]

environment variables or configuration files (e.g., .toml or .yaml) should be possible.

decide whether loading at runtime is necessary
