GreenKube

What's Changed

Added

• Scaleway Kapsule support in NodeCollector: _detect_cloud_provider now recognises Scaleway nodes via k8s.scaleway.com/* labels (primary signal set by the Scaleway Cloud Controller Manager on every Kapsule node) and falls back to node.spec.provider_id starting with scaleway:// for clusters where those labels may be absent. _extract_node_pool returns k8s.scaleway.com/nodepool-name (with nodepool-id as a fallback). Scaleway region mappings (fr-par, nl-ams, pl-waw → Electricity Maps zones) and PUE profile (1.37) were already present in the data layer and are now fully wired up.
• Collector health checks: New HealthCheckService (src/greenkube/core/health.py) that performs periodic connectivity checks against all data sources — Prometheus, OpenCost, Electricity Maps, Boavizta, and Kubernetes. Each probe reports status (healthy, degraded, unreachable, unconfigured), latency, resolved URL, and whether the service was auto-discovered or manually configured.
• GET /api/v1/health/services endpoint: Returns aggregated health status for all data sources with per-service details. Supports ?force=true to bypass the 30-second cache and trigger fresh probes.
• GET /api/v1/health/services/{service_name} endpoint: Returns health status for a single named service.
• POST /api/v1/config/services endpoint: Allows updating service URLs (Prometheus, OpenCost, Boavizta) and the Electricity Maps token at runtime from the frontend. Changes are session-scoped and do not persist across pod restarts.
• Health models: New ServiceHealth, HealthCheckResponse, and ServiceConfigUpdate Pydantic models in src/greenkube/models/health.py.
• Frontend service health overview: The Settings page now displays a color-coded health card for each data source (green=healthy, yellow=degraded, red=unreachable, gray=unconfigured) with latency, URL, and auto-discovery status.
• Frontend service configuration: New "Configure Services" section on the Settings page allows users to override Prometheus URL, OpenCost URL, Electricity Maps token, and Boavizta URL directly from the browser — with immediate health re-check feedback.
• Frontend startup health popup: On first load, if any data source is unreachable or unconfigured, a modal popup alerts the user and offers inline fields to configure the missing service URLs/tokens.
• Sidebar health indicators: The sidebar now shows per-service health dots for all data sources, giving an at-a-glance overview of system health from any page.
• HealthBadge component: Reusable Svelte component (frontend/src/lib/components/HealthBadge.svelte) for color-coded service health indicators.
• HealthPopup component: Modal component (frontend/src/lib/components/HealthPopup.svelte) for first-connection service configuration.
• Health check caching: Results are cached for 30 seconds to avoid hammering external services on repeated page loads.
• CI/CD CLI flags: New --no-color flag (and NO_COLOR env var support) to disable Rich formatting for clean pipeline logs. New --fail-on-recommendations flag on greenkube recommend to exit with code 1 when recommendations are found. New --fail-on-co2-threshold and --fail-on-cost-threshold flags on greenkube report to enforce carbon/cost policy gates in CI/CD pipelines.
• Frontend test suite: Comprehensive Vitest test suite (frontend/tests/) with 133 tests across 8 files covering all JS utility modules (formatters, API client, Svelte stores, ECharts option builders) and Svelte components (StatCard, Card, DataState, HealthBadge) using @testing-library/svelte. Added npm test, npm run test:watch, and npm run test:coverage scripts.
• Test coverage badges in README: Added Python coverage (79%), frontend coverage (93%), and total tests (771 passed) shields.io badges at the top of the README.
