Cozystack v0.37: OpenAPI Dashboard, Lineage Webhook, PVC Expansion in Tenants, and SeaweedFS S3 Discovery

Version 0.37 is a major release that overhauls the platform UI and introduces powerful new infrastructure capabilities.

Major Features and Improvements

New OpenAPI-Based Dashboard

The old Kubeapps-based UI is replaced with a brand-new OpenAPI-based Dashboard. The new dashboard features module-aware navigation, dynamic branding, richer Kubernetes resource views, and is built directly on the Cozystack API schema — making it automatically aware of all available applications and their configuration options.

Lineage Webhook

A new Lineage Webhook automatically tags Pods, PVCs, Services, Ingresses, and Secrets with labels referencing their managing Cozystack application. This creates a clear ownership chain across all platform resources, enabling better visibility and cleanup.

PVC Expansion in Tenant Clusters

Tenant Kubernetes clusters now support PVC expansion via the KubeVirt CSI resizer, allowing users to grow their persistent volumes without recreation.

SeaweedFS as Stacked Service with S3 Discovery

SeaweedFS is updated to v3.99 and restructured as a stacked service. Users can now discover their S3 buckets directly from the dashboard, and the service load balancer IP is visible in the UI.

Smoother Upgrades

Installer and migration handling has been hardened with decoupled CRDs from the API server and better rollout logic. Migration from v0.36.2+ is now smoother.
