greentic-config

Enterprise configuration loader for Greentic hosts. This crate resolves configuration from defaults, user-level config, project config, environment variables, and CLI overrides with clear precedence and provenance tracking.

Features

• Loads canonical schema from greentic-config-types (no secrets).
• Precedence: CLI > env > project > user > defaults.
• Provenance tracking for every resolved field.
• Validation hooks for dev-only fields, path sanity, and unsafe combinations.
• Explain output (string/JSON) for operators.

Services and events mapping

• Services endpoints (e.g., services.events.url) live in greentic-config-types; resolver applies precedence and exposes provenance.
• Events knobs (events.reconnect, events.backoff) get defaults (reconnect enabled, max_retries=50, backoff initial=250ms, max=30s, multiplier=2.0, jitter=true) and validation (offline + remote endpoint is rejected; backoff sanity enforced).
• No secrets in config; route auth material via your secrets backend.

Status

• Schema and loader implemented; CLI binary behind the cli feature (greentic-config show|explain|validate).
• Defaults are non-secret and filesystem/network safe.
