LogicFlowRuntime Controller

[ricardozanini]

Goal

Implement controller to manage Quarkus Flow Runner deployments

Phase: 1 (Months 1-2)

Scope

1. Core Reconciliation

• Watch LogicFlowRuntime resources
• Create/update Deployment (Quarkus Flow Runner pods)
• Create/update Service (HTTP API endpoint)
• Create/update ConfigMap (workflow YAML definitions)
• Handle owner references and garbage collection

2. Durable Workflow Support

• Create Kubernetes Leases (one per replica)
• Create ServiceAccount + Role + RoleBinding for lease management
• Inject lease pool configuration into pods
• Set deployment strategy based on replicas (replicas=1 → Recreate, replicas>1 → RollingUpdate)

3. Status Management

• Update status with deployment readiness
• Track managed LogicFlowDefinitions
• Report lease status
• Set conditions (Ready, DeploymentReady, LeasesReady)

4. Auto-Creation Logic

• Support auto-creation from LogicFlowService
• Apply platform defaults from LogicPlatform

Deliverables

• LogicFlowRuntime controller implementation
• Deployment generation logic
• Service generation logic
• ConfigMap generation logic
• Lease creation logic
• RBAC resource generation
• Status reconciliation
• Unit tests for controller
• Integration tests (envtest)

Success Criteria

• Create LogicFlowRuntime → Deployment + Service + ConfigMap created
• Leases created for durable coordination
• Status reflects deployment readiness
• Delete LogicFlowRuntime → All resources cleaned up
