+# Dual Deployment Architecture: Docker + Kubernetes
+
+**Date:** 2026-04-04
+**Status:** Approved
+**Supersedes:** Portions of `2026-03-29-saas-platform-prd.md` (deployment model, phase ordering, auth strategy)
+
+## Context
+
+Cameleer SaaS must serve two deployment targets:
+- **Docker Compose** — production-viable for small customers and air-gapped installs (single-tenant per stack)
+- **Kubernetes** — managed SaaS and enterprise self-hosted (multi-tenant)
+
+The original PRD assumed K8s-only production. This design restructures the architecture and roadmap to treat Docker Compose as a first-class production target, uses the Docker+K8s dual requirement as a filter for build-vs-buy decisions, and reorders the phase roadmap to ship a deployable product faster.
+
+Key constraints:
+- The application is **always multi-tenant** — Docker deployments have exactly 1 tenant
+- Don't build custom abstractions over K8s-only primitives when no Docker equivalent exists
+- Prefer right-sized OSS tools over Swiss Army knives or custom builds
+- K8s-only features (NetworkPolicies, HPA, Flux CD) are operational enhancements, never functional requirements
+
+## Build-vs-Buy Decisions
+
+### BUY (Use 3rd Party OSS)
+
+| Subsystem | Tool | License | Why This Tool |
+|---|---|---|---|
+| **Identity & Auth** | **Logto** | MPL-2.0 | Lightest IdP (2 containers, ~0.5-1 GB). Orgs, RBAC, M2M tokens, OIDC/SSO federation all in OSS. Replaces ~3-4 months of custom auth build (OIDC, SSO, teams, invites, MFA, password reset, custom roles). |
+| **Reverse Proxy** | **Traefik** | MIT | Native Docker provider (labels) and K8s provider (IngressRoute CRDs). Same mental model in both environments. Already on the k3s cluster. ForwardAuth middleware for tenant-aware routing. Auto-HTTPS via Let's Encrypt. ~256 MB RAM. |
+| **Database** | **PostgreSQL** | PostgreSQL License | Already chosen. Platform data + Logto data (separate schemas). |
+| **Trace/Metrics Storage** | **ClickHouse** | Apache-2.0 | Replaced OpenSearch in the cameleer3-server stack. Columnar OLAP, excellent for time-series observability data. |
+| **Schema Migrations** | **Flyway** | Apache-2.0 | Already in place. |
+| **Billing (subscriptions)** | **Stripe** | N/A (API) | Start with Stripe Checkout for fixed-tier subscriptions. No custom billing infrastructure day 1. |
+| **Billing (usage metering)** | **Lago** (deferred) | AGPL-3.0 | Purpose-built for event-based metering. 8 containers — deploy only when usage-based pricing launches. Design event model with Lago's API shape in mind from day 1. Integrate via API only (keeps AGPL safe). |
+| **GitOps (K8s only)** | **Flux CD** | Apache-2.0 | K8s-only, and that's acceptable. Docker deployments get release tarballs + upgrade scripts. |
+| **Image Builds (K8s)** | **Kaniko** | Apache-2.0 | Daemonless container image builds inside K8s. For Docker mode, `docker build` via docker-java is simpler. |
+| **Monitoring** | **Prometheus + Grafana + Loki** | Apache-2.0 | Works in both Docker and K8s. Optional for Docker (customer's choice), standard for K8s SaaS. |
+| **TLS Certificates** | **Traefik ACME** (Docker) / **cert-manager** (K8s) | MIT / Apache-2.0 | Standard tools, no custom code. |
+| **Container Registry (K8s)** | **Gitea Registry** (SaaS) / **registry:2** (self-hosted) | — | Docker mode doesn't need a registry (local image cache). |
+
+### BUILD (Custom / Core IP)
+
+| Subsystem | Why Build |
+|---|---|
+| **License signing & validation** | Ed25519 signed JWT with tier, features, limits, expiry. Dual mode: online API check + offline signed file. No off-the-shelf tool does this. Core IP. |
+| **Agent bootstrap tokens** | Tightly coupled to the cameleer3 agent protocol (PROTOCOL.md). Custom Ed25519 tokens for agent registration. |
+| **Tenant lifecycle** | CRUD, configuration, status management. Core business logic. User management (invites, teams, roles) is delegated to Logto's organization model. |
+| **Runtime orchestration** | The core of the "managed Camel runtime" product. `RuntimeOrchestrator` interface with Docker and K8s implementations. No off-the-shelf tool does "managed Camel runtime with agent injection." |
+| **Image build pipeline** | Templated Dockerfile: JRE + cameleer3-agent.jar + customer JAR + `-javaagent` flag. Simple but custom. |
+| **Feature gating** | Tier-based feature gating logic. Which features are available at which tier. Business logic. |
+| **Billing integration** | Stripe API calls, subscription lifecycle, webhook handling. Thin integration layer. |
+| **Observability proxy** | Routing authenticated requests to tenant-specific cameleer3-server instances. |
+| **MOAT features** | Debugger, Lineage, Correlation — the defensible product. Built in cameleer3 agent + server. |
+
+### SKIP / DEFER
+
+| Subsystem | Why Skip |
+|---|---|
+| **Secrets management (Vault)** | Docker: env vars + mounted files. K8s: K8s Secrets. Vault is enterprise-tier complexity. Defer until demanded. |
+| **Custom role management UI** | Logto provides this. |
+| **OIDC provider implementation** | Logto provides this. |
+| **WireGuard VPN / VPC peering** | Far future, dedicated-tier only. |
+| **Cluster API for dedicated tiers** | Don't design for this until enterprise customers exist. |
+| **Management agent for updates** | Watchtower is optional for connected customers. Air-gapped gets release tarballs. Don't build custom. |
+
+## Architecture
+
+### Platform Stack (Docker Compose — 6 base containers)
+
+```
+-------------------------------------------------------+
+|  Traefik (reverse proxy, TLS, ForwardAuth)            |
+|  - Docker: labels-based routing                       |
+|  - K8s: IngressRoute CRDs                             |
+--------+---------------------+------------------------+
+         |                     |
+--------v--------+  +---------v-----------+
+| cameleer-saas   |  | cameleer3-server    |
+| (Spring Boot)   |  | (observability)     |
+| Control plane   |  | Per-tenant instance |
+---+-------+-----+  +----------+----------+
+    |       |                    |
+---v--+ +--v----+     +---------v---------+
+| PG   | | Logto |     | ClickHouse        |
+|      | | (IdP) |     | (traces/metrics)  |
+------+ +-------+     +-------------------+
+```
+
+Customer Camel apps are **additional containers** dynamically managed by the control plane via Docker API (Docker mode) or K8s API (K8s mode).
+
+### Auth Flow
+
+```
+User login:
+  Browser -> Traefik -> Logto (OIDC flow) -> JWT issued by Logto
+  
+API request:
+  Browser -> Traefik -> ForwardAuth (cameleer-saas /auth/verify)
+    -> Validates Logto JWT, injects X-Tenant-Id header
+    -> Traefik forwards to upstream service
+
+Machine auth (agent bootstrap):
+  cameleer3-agent -> cameleer-saas /api/agent/register
+    -> Validates bootstrap token (Ed25519)
+    -> Issues agent session token
+    -> Agent connects to cameleer3-server
+```
+
+Logto handles all user-facing identity. The cameleer-saas app handles machine-to-machine auth (agent tokens, license tokens) using Ed25519.
+
+### Runtime Orchestration
+
+```java
+RuntimeOrchestrator (interface)
+  + deployApp(tenantId, appId, envId, imageRef, config) -> Deployment
+  + stopApp(tenantId, appId, envId) -> void
+  + restartApp(tenantId, appId, envId) -> void
+  + getAppLogs(tenantId, appId, envId, since) -> Stream<LogLine>
+  + getAppStatus(tenantId, appId, envId) -> AppStatus
+  + listApps(tenantId) -> List<AppSummary>
+
+DockerRuntimeOrchestrator (docker-java library)
+  - Talks to Docker daemon via /var/run/docker.sock
+  - Creates containers with labels for Traefik routing
+  - Manages container lifecycle
+  - Builds images locally via docker build
+
+KubernetesRuntimeOrchestrator (fabric8 kubernetes-client)
+  - Creates Deployments, Services, ConfigMaps in tenant namespace
+  - Builds images via Kaniko Jobs, pushes to registry
+  - Manages rollout lifecycle
+```
+
+### Image Build Pipeline
+
+```
+Customer uploads JAR
+  -> Validation (file type, size, SHA-256, security scan)
+  -> Templated Dockerfile generation:
+       FROM eclipse-temurin:21-jre-alpine
+       COPY cameleer3-agent.jar /opt/agent/
+       COPY customer-app.jar /opt/app/
+       ENTRYPOINT ["java", "-javaagent:/opt/agent/cameleer3-agent.jar", "-jar", "/opt/app/customer-app.jar"]
+  -> Build:
+       Docker mode: docker build via docker-java (local image cache)
+       K8s mode: Kaniko Job -> push to registry
+  -> Deploy to requested environment
+```
+
+### Multi-Tenancy Model
+
+- **Always multi-tenant.** Docker Compose has 1 pre-configured tenant.
+- **Schema-per-tenant** in PostgreSQL for platform data isolation.
+- **Logto organizations** map 1:1 to tenants. Logto handles user-tenant membership.
+- **ClickHouse** data partitioned by tenant_id.
+- **cameleer3-server** instances are per-tenant (separate containers/pods).
+- **K8s bonus:** Namespace-per-tenant for network isolation, resource quotas.
+
+### Environment Model
+
+Each tenant can have multiple logical environments (tier-dependent):
+
+| Tier | Environments |
+|---|---|
+| Low | prod only |
+| Mid | dev, prod |
+| High+ | dev, staging, prod + custom |
+
+Each environment is a separate deployment of the same app image with different configuration:
+- Docker: separate container, different env vars
+- K8s: separate Deployment, different ConfigMap
+
+Promotion = deploy same image tag to a different environment with that environment's config.
+
+### Configuration Strategy

+### Docker vs K8s Feature Matrix
+
+| Feature | Docker Compose | Kubernetes |
+|---|---|---|
+| Deploy Camel apps | Yes (Docker API) | Yes (K8s API) |
+| Multiple environments | Yes (separate containers) | Yes (separate Deployments) |
+| Agent injection | Yes | Yes |
+| Observability (traces, topology) | Yes | Yes |
+| Identity / SSO / Teams | Yes (Logto) | Yes (Logto) |
+| Licensing | Yes | Yes |
+| Auto-scaling | No | Yes (HPA) |
+| Network isolation (multi-tenant) | Docker networks | NetworkPolicies |
+| GitOps deployment | No (manual updates) | Yes (Flux CD) |
+| Rolling updates | Manual restart | Native |
+| Platform monitoring | Optional (customer adds Grafana) | Standard (Prometheus/Grafana/Loki) |
+| Certificate management | Traefik ACME | cert-manager |
+
+## Revised Phase Roadmap
+
+### Phase 2: Tenants + Identity + Licensing
+**Goal:** A customer can sign up, get a tenant, and access the platform via Traefik.
+
+- Integrate Logto as identity provider
+  - Replace custom user-facing auth (login, registration, password management)
+  - Keep Ed25519 JWT for machine tokens (agent bootstrap, license signing)
+  - Configure Logto organizations to map to tenants
+- Tenant entity + CRUD API
+- License token generation (Ed25519 signed JWT: tier, features, limits, expiry)
+- Traefik integration with ForwardAuth middleware
+- Docker Compose production stack (6 containers)
+- Externalize Ed25519 keys (mounted files, not per-boot)
+
+**Files to modify/create:**
+- `src/main/java/net/siegeln/cameleer/saas/tenant/` — new package
+- `src/main/java/net/siegeln/cameleer/saas/license/` — new package
+- `src/main/java/net/siegeln/cameleer/saas/config/SecurityConfig.java` — Logto OIDC integration
+- `src/main/resources/db/migration/V005__create_tenants.sql`
+- `src/main/resources/db/migration/V006__create_licenses.sql`
+- `docker-compose.yml` — expand to full production stack
+- `traefik.yml` — static config
+- `src/main/resources/application.yml` — Logto + Traefik config
+
+### Phase 3: Runtime Orchestration + Environments
+**Goal:** Customer can upload a Camel JAR, deploy it to dev/prod, see it running with agent attached.
+
+- `RuntimeOrchestrator` interface
+- `DockerRuntimeOrchestrator` implementation (docker-java)
+- Customer JAR upload endpoint
+- Image build pipeline (Dockerfile template + docker build)
+- Logical environment model (dev/test/prod per tenant)
+- Environment-specific config overlays
+- App lifecycle API (deploy, start, stop, restart, logs, health)
+
+**Key dependencies:** docker-java, Kaniko (for future K8s)
+
+### Phase 4: Observability Pipeline
+**Goal:** Customer can see traces, metrics, and route topology for deployed apps.
+
+- Connect cameleer3-server to customer app containers
+- ClickHouse tenant-scoped data partitioning
+- Observability API proxy (tenant-aware routing to cameleer3-server)
+- Basic topology graph endpoint
+- Agent ↔ server connectivity verification
+
+### Phase 5: K8s Operational Layer
+**Goal:** Same product works on K8s with operational enhancements.
+
+- `KubernetesRuntimeOrchestrator` implementation (fabric8)
+- Kaniko-based image builds
+- Flux CD integration for platform GitOps
+- Namespace-per-tenant provisioning
+- NetworkPolicies, ResourceQuotas
+- Helm chart for K8s deployment
+- Registry integration (Gitea registry / registry:2)
+
+### Phase 6: Billing
+**Goal:** Customers can subscribe and pay.
+
+- Stripe Checkout integration
+- Subscription lifecycle (create, upgrade, downgrade, cancel)
+- Tier enforcement (feature gating based on active subscription)
+- Usage tracking in platform DB (prep for Lago integration later)
+- Webhook handling for payment events
+
+### Phase 7: Security Hardening + Monitoring
+**Goal:** Production-hardened platform.
+
+- Prometheus/Grafana/Loki stack (optional Docker compose overlay, standard K8s)
+- SOC 2 compliance review
+- Rate limiting
+- Container image signing (cosign)
+- Supply chain security (SBOM, Trivy scanning)
+- Audit log shipping to separate sink
+
+### Frontend (React Shell) — Parallel Track (Phase 2+)
+- Can start as soon as Phase 2 API contracts are defined
+- Uses `@cameleer/design-system`
+- Screens: login, dashboard, app deployment, environment management, observability views, team management, billing
+
+## Verification Plan
+
+### Phase 2 Verification
+1. `docker compose up` starts all 6 containers
+2. Navigate to Logto admin, create a user
+3. User logs in via OIDC flow through Traefik
+4. API calls with JWT include `X-Tenant-Id` header
+5. License token can be generated and verified
+6. All existing tests still pass
+
+### Phase 3 Verification
+1. Upload a sample Camel JAR via API
+2. Platform builds container image
+3. Deploy to "dev" environment
+4. Container starts with cameleer3 agent attached
+5. App is reachable via Traefik routing
+6. Logs are accessible via API
+7. Deploy same image to "prod" with different config
+
+### Phase 4 Verification
+1. Running Camel app sends traces to cameleer3-server
+2. Traces visible in ClickHouse with correct tenant_id
+3. Topology graph shows route structure
+4. Different tenant cannot see another tenant's data
+
+### Phase 5 Verification
+1. Helm install deploys full platform to k3s
+2. Tenant provisioning creates namespace + resources
+3. App deployment creates K8s Deployment + Service
+4. Kaniko builds image and pushes to registry
+5. NetworkPolicy blocks cross-tenant traffic
+6. Same API contracts work as Docker mode
+
+### End-to-End Smoke Test (Any Phase)
+```bash
+# Docker Compose
+docker compose up -d
+# Create tenant + user via API/Logto
+# Upload sample Camel JAR
+# Deploy to environment
+# Verify agent connects to cameleer3-server
+# Verify traces in ClickHouse
+# Verify observability API returns data
+```
