From 220975aef75904b3bea17848131ad43d11decdf3 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 19 Nov 2025 00:01:46 +0000 Subject: [PATCH 01/30] fix(api): gracefully handle missing ApplicationInstall CRD When the ApplicationInstall CRD is not registered in the Kubernetes cluster, the InstallApplication handler now logs a warning and continues with the database record creation instead of returning a 500 error. This change: - Allows the API to work in development without the full K8s CRD setup - Provides a helpful message showing how to install the missing CRD - Still creates the database record so the UI can display applications - Maintains existing error handling for other K8s errors The user should install the CRD for full functionality: kubectl apply -f manifests/crds/applicationinstall.yaml --- api/internal/handlers/applications.go | 79 ++++++++++++++------------- 1 file changed, 41 insertions(+), 38 deletions(-) diff --git a/api/internal/handlers/applications.go b/api/internal/handlers/applications.go index 154d6a2a..38e66471 100644 --- a/api/internal/handlers/applications.go +++ b/api/internal/handlers/applications.go @@ -198,49 +198,52 @@ func (h *ApplicationHandler) InstallApplication(c *gin.Context) { return } - // Step 3: Create ApplicationInstall CRD + // Step 3: Create ApplicationInstall CRD (optional - for controller to create Template) // The controller will watch this and create the corresponding Template CRD - if h.k8sClient == nil { - log.Printf("Error: k8sClient is nil, cannot create ApplicationInstall for %s", name) - c.JSON(http.StatusInternalServerError, ErrorResponse{ - Error: "Kubernetes client not configured", - Message: "Cannot install application: Kubernetes client is not available.

Changes: - Add NATS event architecture design document - Create events package with types, subjects, and publisher - Add NATS dependency to go.mod (v1.37.0) - Add database tables: platform_controllers, event_log - Add platform fields to installed_applications and sessions tables The API will publish events to NATS subjects, and platform-specific controllers will subscribe and perform the actual operations. This decouples the API from Kubernetes and allows multiple platform controllers to run simultaneously. Next steps: - Update API handlers to publish NATS events instead of direct K8s calls - Update controller to subscribe to NATS events - Add NATS to docker-compose for development --- api/go.mod | 4 +

Subject: [PATCH 12/30] feat(api): add database-based session queries for multi-platform support - Create SessionDB with comprehensive session management methods - Add database migrations for new session fields (pod_name, memory, cpu, etc.) - Update ListSessions and GetSession to use database with k8s fallback - Add conversion functions for database sessions to API response format - Update cacheSessionInDB to use SessionDB for consistency This enables platform-agnostic session queries from the database, with automatic fallback to Kubernetes for backward compatibility. ---

Subject: [PATCH 13/30] feat(scripts): add Docker Compose development scripts for NATS architecture Add comprehensive development scripts for the new NATS-based multi-platform architecture: New scripts: - docker-dev.sh: Start Docker Compose environment with NATS/PostgreSQL - docker-dev-stop.sh: Stop development environment with cleanup options - build-docker-controller.sh: Build Docker platform controller image - test-nats.sh: Test NATS connectivity, publish/subscribe events Updated scripts: - local-build.sh: Add Docker controller image build - local-teardown.sh: Add Docker controller image cleanup - local-port-forward.sh: Add NATS port forwarding support - README.md: Document new Docker Compose development workflow --- scripts/README.md | 84 +++++++

Key Concepts

Architecture

-

StreamSpace consists of three main components:

+

StreamSpace uses a multi-platform event-driven architecture with NATS messaging:

-

1. Kubernetes Controller

-

Go-based controller using Kubebuilder framework that manages Session and Template CRDs.

+

1. Platform Controllers

+

Platform-specific controllers that manage sessions on their respective infrastructure via NATS events.

    -
  • Reconciles Session CRDs with Kubernetes resources
    • -
  • Creates Deployments, Services, Ingresses, PVCs
    • -
  • Handles state transitions and hibernation
    • -
  • Exports Prometheus metrics
    • +
  • Kubernetes Controller (k8s-controller/) - Kubebuilder-based, manages CRDs
    • +
  • Docker Controller (docker-controller/) - Manages Docker containers
    • +
  • NATS JetStream for durable event delivery
    • +
  • Prometheus metrics export
