··· 8 8 9 9 **Sync Architecture**: The operator implements **unidirectional sync from HSM to Kubernetes Secrets only**. HSM is the authoritative source of truth. K8s Secrets are read-only replicas that get updated when HSM data changes. There is no K8s → HSM sync functionality. 10 10 11 11 + **GitOps Deployment**: This Kubernetes deployment is GitOps-based. You are not able to push new images to the Kubernetes cluster from this machine. Code changes require updating the deployment through the GitOps pipeline. 12 12 + 13 13 + **Code Modernization**: Avoid keeping legacy code whenever possible. Replace and improve functions as necessary rather than maintaining backward compatibility with outdated patterns. 14 14 + 11 15 ## Project Overview 12 16 13 17 A Kubernetes operator that bridges Hardware Security Module (HSM) data storage with Kubernetes Secrets, providing true secret portability through hardware-based security. The operator implements a controller pattern that synchronizes HSM binary data files to Kubernetes Secret objects using a unified binary architecture with gRPC communication, automatic USB device discovery, and dynamic agent deployment. ··· 43 47 **Race-Free Coordination:** 44 48 - HSMDevice CRDs contain readonly specifications only (no status field) 45 49 - Discovery pods report via their own pod annotations 46 46 - - HSMPool CRDs aggregate all discovery reports from multiple nodes 50 50 + - **HSMPool CRDs are the source of truth** for agent discovery and multi-device operations 51 51 + - HSMPool aggregates all discovery reports from multiple nodes 47 52 - Owner references ensure automatic cleanup when resources are deleted 48 53 - 5-minute grace periods prevent agent churn during outages 49 54 55 55 + **Multi-Device Agent Architecture:** 56 56 + - **HSMPool-based Agent Discovery**: API and controllers query HSMPool to find all agent instances for a device type 57 57 + - **Multiple Agent Instances**: Each physical device gets its own agent pod (e.g., `hsm-agent-pico-hsm-0`, `hsm-agent-pico-hsm-1`) 58 58 + - **Multi-Agent Operations**: API operations (list, write, delete) work across all agents when mirroring is enabled 59 59 + - **Automatic Synchronization**: HSMSyncReconciler handles conflict detection and resolution between devices 60 60 + 50 61 **gRPC Communication Architecture:** 51 62 - Protocol definition in `api/proto/hsm/v1/hsm.proto` with 10 HSM operations 52 63 - Manager ↔ Agent: gRPC for efficient, type-safe HSM operations 53 64 - Discovery → Manager: Pod annotations for race-free device reporting 54 54 - - External → Manager: REST API proxy routing to appropriate agents 65 65 + - **External → Manager**: REST API proxy routes to ALL agents for multi-device operations 55 66 - Generated code: `api/proto/hsm/v1/hsm.pb.go` and `hsm_grpc.pb.go` 56 67 57 68 **Controller Hierarchy:** ··· 60 71 ├── HSMSecretReconciler - HSM to K8s Secret sync 61 72 ├── HSMPoolReconciler - Aggregates discovery reports from pod annotations 62 73 ├── HSMPoolAgentReconciler - Deploys agents when pools are ready 74 74 + ├── HSMSyncReconciler - Multi-device HSM synchronization and conflict resolution 63 75 └── DiscoveryDaemonSetReconciler - Manages discovery DaemonSet lifecycle 64 76 65 77 Discovery Controllers: ··· 255 267 # Monitor sync status 256 268 kubectl get hsmsecret my-secret -o jsonpath='{.status.syncStatus}' 257 269 258 258 - # Check discovered devices 270 270 + # Check discovered devices in HSMPool (source of truth for agents) 259 271 kubectl get hsmpool -o jsonpath='{.status.aggregatedDevices[*].devicePath}' 272 272 + 273 273 + # Check HSMPool readiness for agent deployment 274 274 + kubectl get hsmpool -o custom-columns=NAME:.metadata.name,PHASE:.status.phase,DEVICES:.status.totalDevices 275 275 + 276 276 + # View all agent pods for multi-device setup 277 277 + kubectl get pods -l app.kubernetes.io/name=hsm-agent 260 278 261 279 # View discovery pod reports 262 280 kubectl get pods -l app.kubernetes.io/component=discovery \ ··· 308 326 2. `HSMPoolReconciler` aggregates device discovery reports from pod annotations (race-free) 309 327 3. `HSMPoolAgentReconciler` deploys agents dynamically when devices are ready 310 328 4. `HSMSyncReconciler` handles multi-device HSM synchronization (HSM ↔ HSM only) 329 329 + 330 330 + **Agent Discovery Architecture:** 331 331 + - **HSMPool as Source of Truth**: API and controllers query HSMPool.Status.AggregatedDevices instead of individual HSMDevice resources 332 332 + - **Multi-Instance Agent Tracking**: Agent manager tracks agents by keys like `pico-hsm-0`, `pico-hsm-1` for multiple physical devices 333 333 + - **Pool-Based Cleanup**: Agent cleanup based on HSMSecret existence rather than device-specific references 334 334 + - **API Multi-Device Operations**: 335 335 + - `findAvailableAgent()` queries HSMPools to find any available agent for a device type 336 336 + - `getAllAvailableAgents()` returns all agents across all pools for mirroring operations 337 337 + - Operations like delete/write with `mirror=true` target ALL agents simultaneously 311 338 312 339 **PKCS#11 Client Implementation:** 313 340 - Production: `internal/hsm/pkcs11_client.go` with CGO
