Add provisioning controller and REST API for managed warehouses#332
Conversation
Adds end-to-end provisioning flow: PostHog calls a REST API to initiate provisioning, the controller drives Crossplane via Duckling CRs to create per-team AWS resources (Aurora, S3, IAM), and updates the config store as resources come up. The team router gates worker stack creation on warehouse readiness and uses per-team namespace/SA from the warehouse config. New packages: - controlplane/provisioner: reconciliation loop + K8s dynamic client for Duckling CRs (pending→provisioning→ready, deleting→deleted, failure handling) - controlplane/provisioning: production-facing REST API on separate port (POST /teams/:id/provision, POST /teams/:id/deprovision, GET /teams/:id/warehouse) Key design decisions: - Provisioning API runs on separate port (:9091) from admin (:9090) - Separate bearer token (--provisioning-token) for provisioning vs admin - Controller uses WarehouseStore interface for testability - CAS (compare-and-swap) updates prevent state races - Synced=False tolerance (5min grace period) for Crossplane transients - Teams are auto-created on first provision call - Non-K8s builds get stub (provisioning package has no build tag) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
