## P0-RBAC-001 Validation Results ✅ **Both fixes working correctly**: - RBAC permissions (commit e22969f): Agent can read Template/Session CRDs - API manifest inclusion (commit 8d01529): Template manifest included in payload **Evidence**: - Agent successfully fetches templates from K8s (no 403 errors) - API includes manifest in WebSocket command - Both fixes validated and production-ready ## New Issue Discovered: P0-MANIFEST-001 🔴 **Template manifest case mismatch blocks session provisioning** **Root Cause**: - Database manifest has capitalized field names: "Spec", "Ports", "BaseImage" - Agent parsing expects lowercase: "spec", "ports", "baseImage" - Parsing fails → Agent falls back to K8s → Template CRD schema mismatch → Deployment fails **Impact**: BLOCKS all session creation despite P0-RBAC-001 fixes working **Fix Required**: Add JSON struct tags to template structs in api/internal/sync/parser.go **Files**: - BUG_REPORT_P0_TEMPLATE_MANIFEST_CASE_MISMATCH.md (comprehensive analysis) - P0_RBAC_001_VALIDATION_RESULTS.md (validation report) **Session Tested**: admin-firefox-browser-bc0bee20 (stuck in pending, no pod created) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
The TemplateManifest struct had yaml tags but was missing json tags. When marshaled to JSON, Go's default behavior uses capitalized field names (e.g., 'Spec', 'BaseImage', 'Ports'), but the agent's parsing code expects lowercase camelCase field names (e.g., 'spec', 'baseImage', 'ports') matching Kubernetes CRD conventions. This caused the agent to fail parsing template manifests with: 'failed to parse template manifest: invalid template spec' Fix: Added json tags to all fields in TemplateManifest struct to ensure lowercase camelCase serialization when stored in the database. Changes: - Added json tags to APIVersion, Kind, Metadata, and all Spec fields - Ensures compatibility with agent's parseTemplateCRD() function - Maintains existing yaml tags for repository sync functionality Root cause: api/internal/sync/parser.go line 326 marshals to JSON without json tags, causing capitalized field names. Resolves: P0-MANIFEST-001
…orking ## P0-MANIFEST-001 Validation Results ✅ **FIX COMPLETELY VALIDATED AND WORKING** **JSON Struct Tags Fix** (commit c092e0c): - Added json tags to all TemplateManifest fields - Templates re-synced with lowercase field names - Agent successfully parsing manifests from payload **Session Provisioning Evidence**: - ✅ Template parsed: firefox-browser (ports: 1) - ✅ Deployment created - ✅ Service created (ClusterIP: 10.110.232.135, Port: 3000) - ✅ Pod running: admin-firefox-browser-d40f9190-584bc6576f-5b9z9 (1/1 Ready) - ✅ Session started successfully in 6 seconds **Database Verification**: ```json { "spec": {"baseImage": "...", "ports": [{"containerPort": 3000}]} } ``` All field names now lowercase (baseImage, ports, containerPort) **Agent Logs**: ``` [K8sOps] Parsed template from payload: firefox-browser (ports: 1) [StartSessionHandler] Session started successfully ``` **Minor Issue** (P1 - not blocking): - Agent needs pods/portforward RBAC permission for VNC tunnel - Session pods working correctly, VNC tunneling separate issue **Recommendation**: ✅ APPROVE FOR PRODUCTION 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
…ission for VNC tunneling
…tunneling The agent needs pods/portforward permission to create port-forwards from the agent to session pods for VNC streaming through the control plane VNC proxy. Without this permission, VNC tunnel creation fails with: 'User "system:serviceaccount:streamspace:streamspace-agent" cannot create resource "pods/portforward" in API group "" in the namespace "streamspace"' Impact: - Sessions provision successfully (pods running) - VNC streaming through control plane blocked - Direct pod VNC access works (workaround available) Fix: - Added pods/portforward permission with create and get verbs - Applied to both standalone RBAC (agents/k8s-agent/deployments/rbac.yaml) - Applied to Helm chart RBAC (chart/templates/rbac.yaml) - Scoped to streamspace namespace (Role, not ClusterRole) VNC Proxy Architecture (v2.0-beta): User Browser → Control Plane VNC Proxy → Agent VNC Tunnel → Session Pod Changes: - agents/k8s-agent/deployments/rbac.yaml: Added pods/portforward rule - chart/templates/rbac.yaml: Added pods/portforward rule Resolves: P1-VNC-RBAC-001
…onal - Merged Builder's P1-VNC-RBAC-001 fix (commit e586f24) - Added pods/portforward RBAC permission to agent - Validated VNC tunnel creation (2-second setup, no RBAC errors) - VNC proxy architecture fully operational - Integration testing unblocked (VNC-dependent tests can proceed) Validation Results: - ✅ VNC tunnel created successfully - ✅ Port-forward established: localhost:34045 -> pod:3000 - ✅ No RBAC errors - ✅ 2-second tunnel creation time (excellent) - ✅ Production ready All P0 and P1 issues now resolved.

… on heartbeats The UpdateAgentHeartbeat function was only updating last_heartbeat timestamp but not the status field, causing the database to show agents as 'offline' even though they were connected via WebSocket and sending heartbeats. This caused the AgentSelector to reject all session creation requests with HTTP 503 'No online agents available' despite agents being connected and healthy. Root Cause: - In-memory WebSocket state: Agent connected, heartbeats received - Database state: status = 'offline' (never updated on heartbeat) - AgentSelector queries database for status = 'online' - Result: Zero sessions could be created Impact: - CRITICAL: Complete session creation failure (HTTP 503) - Discovered during Integration Test 3.1 (Agent Failover) - Blocks all integration testing requiring session creation Fix: - Updated UpdateAgentHeartbeat() to set status = 'online' on every heartbeat, ensuring database state matches WebSocket connection state - handleRegister() already sets status = 'online' on connect (working) - handleUnregister() already sets status = 'offline' on disconnect (working) Changes: - api/internal/websocket/agent_hub.go:478 - Added status = 'online' to UPDATE agents query in UpdateAgentHeartbeat() Agent Lifecycle (After Fix): 1. Agent connects → handleRegister() → status = 'online' ✓ 2. Agent sends heartbeat → UpdateAgentHeartbeat() → status = 'online' ✓ 3. Agent disconnects → handleUnregister() → status = 'offline' ✓ Resolves: P1-AGENT-STATUS-001
The Docker Agent is a standalone binary that runs on Docker hosts and connects to the Control Plane via WebSocket. It enables StreamSpace to manage sessions on Docker infrastructure alongside Kubernetes. Features Implemented: - Complete agent structure with WebSocket connection - Agent registration and heartbeat mechanism - Single-writer pattern for WebSocket communication - Docker client integration with daemon verification - Configuration management via flags and environment variables - Graceful shutdown and cleanup - Multi-stage Dockerfile for production deployment - Comprehensive README with deployment guides Architecture: - Agent connects TO Control Plane (outbound, firewall-friendly) - Command-driven session lifecycle (start/stop/hibernate/wake) - Manages Docker containers, networks, and volumes - VNC tunneling support (planned) - Resource monitoring and capacity management Files Added: - agents/docker-agent/main.go (589 lines) - Core agent implementation - agents/docker-agent/internal/config/config.go - Configuration management - agents/docker-agent/internal/errors/errors.go - Error definitions - agents/docker-agent/go.mod - Go module dependencies - agents/docker-agent/Dockerfile - Multi-stage container build - agents/docker-agent/README.md - Documentation and deployment guides TODO (Deferred to Next Commits): - Docker operations module (container/network/volume management) - Command handlers (start/stop/hibernate/wake session) - Message handler (WebSocket message processing) - VNC handler and tunnel implementation Build Status: ✅ Compiles successfully (10MB binary) Dependencies: - github.com/docker/docker v24.0.7+incompatible - github.com/gorilla/websocket v1.5.1 This completes the basic docker-agent framework. Command handlers and Docker operations will be implemented in subsequent commits. Related: v2.0 multi-platform architecture (K8s + Docker + VM + Cloud)
Completed the docker-agent implementation with full session lifecycle
management capabilities. The agent can now start and stop sessions on
Docker hosts via Control Plane commands.
Features Implemented:
1. Docker Operations Module (agent_docker_operations.go, 583 lines):
- Template parsing from Control Plane payload
- Container creation with resource limits (CPU/memory)
- Image pulling and caching
- Container lifecycle management (create/start/stop/remove)
- Network management (ensure StreamSpace network exists)
- Volume mounting for persistent storage
- Resource parsing (Gi/Mi/G/M for memory, millicores for CPU)
2. Command Handlers (agent_handlers.go, 268 lines):
- StartSessionHandler: Creates and starts session containers
- StopSessionHandler: Stops and removes session containers
- HibernateSessionHandler: Placeholder for container pause
- WakeSessionHandler: Placeholder for container unpause
- Success/error response handling to Control Plane
3. Message Handler (agent_message_handler.go, 111 lines):
- WebSocket message routing (command/ping/shutdown)
- Command dispatching to appropriate handlers
- Ping/pong for connection keepalive
- Graceful shutdown handling
4. Main Integration:
- Wired command handlers into agent initialization
- Connected message handler to WebSocket readPump
- Complete end-to-end message flow
Session Lifecycle Flow:
1. Control Plane sends start_session command via WebSocket
2. Agent parses template manifest from payload
3. Agent ensures network exists
4. Agent creates container with resource limits
5. Agent starts container and waits for running state
6. Agent sends success response with container ID and IP
7. Control Plane can send stop_session to cleanup
Docker Operations:
- Container naming: streamspace-{sessionId}
- Network: Configurable (default: streamspace)
- Volumes: Per-session persistent home volumes
- Resource limits: Memory and CPU from template or command
- Port bindings: Automatic host port assignment
Build Status: ✅ Compiles successfully (10MB binary)
TODO (Future Enhancements):
- VNC tunnel support (port-forward to session containers)
- Hibernate/wake implementation (container pause/unpause)
- Resource monitoring and reporting
- Auto-cleanup of orphaned containers
- Health checks and auto-recovery
Files Added/Modified:
- agent_docker_operations.go (NEW, 583 lines)
- agent_handlers.go (NEW, 268 lines)
- agent_message_handler.go (NEW, 111 lines)
- main.go (MODIFIED, wired handlers)
The docker-agent is now functionally complete for basic session
management and ready for integration testing with Control Plane.

### P1-COMMAND-SCAN-001 Fix: NULL Handling for ErrorMessage
**Problem**: CommandDispatcher crashes when scanning pending commands with NULL error_message
**Root Cause**: ErrorMessage field type mismatch (string cannot accept NULL from database)
**Files Modified**:
- api/internal/models/agent.go (ErrorMessage string → *string)
- api/internal/api/handlers.go (4 pointer assignments for NULL-safe scanning)
**Impact**:

- ✅ Test 3.2 (Command Retry) unblocked
**Code Changes**:
```go
// api/internal/models/agent.go
type AgentCommand struct {
ErrorMessage *string // Now accepts NULL as nil pointer
}
// api/internal/api/handlers.go
if errorMessage.Valid {
cmd.ErrorMessage = &errorMessage.String // Pointer assignment
}
```

- Root Cause: CommandDispatcher expects updated_at column in agent_commands table, but it was missing from the schema. This caused UPDATE queries to fail with 'column does not exist' error when marking commands as failed. - Fix: Added migration 004 to add updated_at column with: * DEFAULT CURRENT_TIMESTAMP for new rows * Backfill existing rows with created_at value * Auto-update trigger to maintain timestamp on UPDATEs - Impact: Enables accurate command status tracking and audit logging. Failed commands can now be properly marked and timestamped.

…ked AgentHub
PROBLEM:
- AgentHub stored connections in-memory per pod
- Multiple API replicas caused "No agents available" errors
- Agent connections only visible to the pod they connected to
- Commands failed when routed to different API pods
SOLUTION:
Implemented optional Redis integration for AgentHub state sharing:
1. **AgentHub Redis Integration** (api/internal/websocket/agent_hub.go):
- Added redis.Client and podName fields to AgentHub struct
- New NewAgentHubWithRedis() constructor for multi-pod mode
- Store agent→pod mapping in Redis: agent:{agentID}:pod
- Store connection state: agent:{agentID}:connected (5min TTL)
- Refresh TTL on heartbeats for active agents
- Redis pub/sub for cross-pod command routing
- Pod-specific channels: pod:{podName}:commands
- Backwards compatible: NewAgentHub() works without Redis
2. **Main.go Integration** (api/cmd/main.go):
- Initialize separate Redis client for AgentHub (DB 1)
- Environment variable: AGENTHUB_REDIS_ENABLED=true/false
- Auto-detect POD_NAME from Kubernetes downward API
- Graceful fallback to single-pod mode on Redis failure
- Proper cleanup on shutdown
3. **Helm Chart Updates**:
- Added POD_NAME env var using Kubernetes fieldRef
- Added AGENTHUB_REDIS_ENABLED configuration
- New values.yaml option: redis.agentHubEnabled (default: true)
- Automatic configuration when redis.enabled=true
BENEFITS:
✅ Horizontal API scaling: Run unlimited API replicas
✅ Load balancing: Distribute agent connections across pods
✅ High availability: Agents can reconnect to any pod
✅ Optional: Redis not required for single-pod deployments
✅ Backwards compatible: Existing deployments work unchanged
DEPLOYMENT:
For multi-pod mode:
1. Set redis.enabled=true in Helm values
2. Scale API: kubectl scale deployment streamspace-api --replicas=3
3. AgentHub automatically uses Redis for state sharing
For single-pod mode (no changes needed):
1. Keep redis.enabled=false (default)
2. AgentHub uses in-memory connections only
TESTING:
- Build verified (no compilation errors)
- Redis DB 1 for AgentHub, DB 0 for cache (isolation)
- 5-minute TTL prevents stale agent entries
- Pub/sub routing enables cross-pod commands

ENHANCEMENT:
Enable multiple k8s-agent replicas for the SAME cluster with active-standby
failover using Kubernetes leader election.
PROBLEM (Before):
- Only one k8s-agent replica could run per cluster
- Agent failure caused complete outage until pod restarted
- No automatic failover for agent high availability
- Manual intervention required for agent recovery
SOLUTION:
Implemented Kubernetes leader election for agent HA:
1. **Leader Election Module** (agents/k8s-agent/internal/leaderelection/):
- Uses k8s.io/client-go/tools/leaderelection
- Lease-based leader election (coordination.k8s.io/leases)
- Configurable lease duration (default: 15s)
- Automatic leader re-election on failure
- Pod identity from POD_NAME environment variable
2. **Agent Integration** (agents/k8s-agent/main.go):
- New --enable-ha flag (or ENABLE_HA env var)
- runWithLeaderElection() for HA mode
- runStandalone() for single-instance mode
- Only leader runs agent logic (WebSocket connection to Control Plane)
- Standby replicas wait and automatically take over on leader failure
- Graceful leadership transitions
- Leader logs: "🎖️ I am the LEADER - starting agent..."
- Standby logs: "New leader elected: <pod-name> (I am standby)"
3. **Helm Chart Configuration** (chart/):
- values.yaml: k8sAgent.ha.enabled (default: false)
- values.yaml: k8sAgent.replicaCount supports 2+ for HA
- k8s-agent-deployment.yaml: ENABLE_HA environment variable
- k8s-agent-deployment.yaml: POD_NAME from fieldRef (metadata.name)
- rbac.yaml: Added coordination.k8s.io/leases permissions for leader election
ARCHITECTURE:
**Single-Pod Mode (ha.enabled=false, replicaCount=1)**:
- Traditional deployment
- One active agent per cluster
- Auto-restart on failure (Kubernetes liveness probe)
**HA Mode (ha.enabled=true, replicaCount=2+)**:
```

Control Plane API
(WebSocket Connection)
```
- Pod 1 becomes leader, starts agent, connects to Control Plane
- Pod 2 waits in standby mode
- If Pod 1 fails:
* Lease expires (15s default)
* Pod 2 wins election automatically
* Pod 2 becomes leader, starts agent
* Control Plane sees agent reconnect (same agentId)
* Seamless failover with minimal downtime (~15-20s)
USAGE:
**Enable HA Mode:**
```yaml
# values.yaml
k8sAgent:
replicaCount: 2 # or 3 for extra redundancy
ha:
enabled: true # Enable leader election
```
**Or via command-line:**
```bash
helm install streamspace ./chart \
--set k8sAgent.replicaCount=2 \
--set k8sAgent.ha.enabled=true
```
**Verify Leadership:**
```bash
# Check which pod is leader
kubectl logs -n streamspace deployment/streamspace-k8s-agent | grep "leader"
# Expected output:
# Pod 1: "[LeaderElection] 🎖️ Became leader for agent: k8s-prod-cluster"
# Pod 2: "[LeaderElection] New leader elected: streamspace-k8s-agent-abc123 (I am standby)"
```
**Test Failover:**
```bash
# Delete leader pod
kubectl delete pod -n streamspace <leader-pod-name>
# Watch standby become leader (within 15-20 seconds)
kubectl logs -n streamspace -f deployment/streamspace-k8s-agent
```
BENEFITS:
✅ Automatic failover on agent failure (15-20s downtime)
✅ Zero manual intervention required
✅ Multiple replicas provide redundancy
✅ Backwards compatible (HA disabled by default)
✅ Minimal resource overhead (only leader is active)
✅ Production-ready high availability
CONFIGURATION:
- Lease Duration: 15 seconds (non-leader waits to acquire)
- Renew Deadline: 10 seconds (leader must renew within)
- Retry Period: 2 seconds (re-attempt interval)
LIMITATIONS:
- Only one active agent per cluster at a time (by design)
- Leadership transition takes ~15-20 seconds
- Requires Kubernetes 1.14+ (Lease resource)
COMPATIBILITY:
- ✅ Works with existing single-pod deployments (HA off by default)
- ✅ Compatible with all agent features (VNC tunneling, session management)
- ✅ No API changes required
- ✅ Seamless upgrade path

…patibility
**Problem:**
- UI connect button was greyed out for running sessions
- UI expects status.phase === 'Running' (capital R)
- API WebSocket sent status.phase === 'running' (lowercase r)
- Case mismatch prevented connect button from enabling
**Solution:**
- Added strings.Title() to capitalize state before sending to UI
- Changed: status["phase"] = state → status["phase"] = strings.Title(state)
- Now sends "Running", "Pending", "Terminated", etc. (capitalized)
**Files Changed:**
- api/internal/websocket/handlers.go:
- Added strings import
- Line 366: Capitalize state with strings.Title()
**Testing:**
- Session state "running" now sent as "Running" to UI
- Connect button enabled when status.phase === 'Running'
**Related:**
- UI code at ui/src/components/SessionCard.tsx:270
- disabled={session.status.phase !== 'Running' || !session.status.url}

…y for Selkies, Kasm, and Guacamole sessions, including UI and database schema updates.
Same pattern as Issues #229 and #233 - migration file exists but wasn't included in the inline migrations array in database.go. Migration 008 adds: - streaming_protocol column (VARCHAR(50), default 'vnc') - streaming_port column (INTEGER, default 5900) - streaming_path column (VARCHAR(255), for URL-based protocols) - Index on streaming_protocol for fast queries - Updates existing sessions to have explicit VNC values This enables StreamSpace to support multiple streaming technologies (VNC, Selkies, Guacamole, X2Go, RDP, etc.) beyond just VNC. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
The security headers middleware was blocking VNC session viewer from loading in iframes due to X-Frame-Options: DENY and CSP frame-ancestors 'none'. Changed to allow SAMEORIGIN framing for VNC proxy paths: - /api/v1/http/* (HTTP proxy for VNC) - /api/v1/vnc/* (VNC WebSocket) - /api/v1/websockify/* (WebSocket proxy) These paths now use: - X-Frame-Options: SAMEORIGIN - frame-ancestors 'self' All other paths retain strict DENY/none policy for clickjacking protection. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Remove dependency on agentHub.IsAgentConnected() which only works on the local pod's in-memory WebSocket connections. In multi-pod API deployments without Redis, this caused "no agents available" errors because the agent might be connected to a different pod. Changes: - filterAgents: Use status='online' from database instead of local WebSocket check. The database is shared across all pods. - getOnlineAgents: Add 90-second heartbeat freshness check to ensure we only select agents with recent heartbeats This allows multi-pod API deployments to work correctly without Redis. Redis is still recommended for production HA (for real-time agent status updates), but this fix ensures basic functionality works. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
