+# Cameleer SaaS -- How to Install, Start & Bootstrap
+
+## Quick Start (Development)
+
+```bash
+# 1. Clone
+git clone https://gitea.siegeln.net/cameleer/cameleer-saas.git
+cd cameleer-saas
+
+# 2. Create environment file
+cp .env.example .env
+
+# 3. Generate Ed25519 key pair
+mkdir -p keys
+ssh-keygen -t ed25519 -f keys/ed25519 -N ""
+mv keys/ed25519 keys/ed25519.key
+
+# 4. Start the stack
+docker compose -f docker-compose.yml -f docker-compose.dev.yml up -d
+
+# 5. Wait for services to be ready (~30s)
+docker compose logs -f cameleer-saas --since 10s
+# Look for: "Started CameleerSaasApplication"
+
+# 6. Verify
+curl http://localhost:8080/actuator/health
+# {"status":"UP"}
+```
+
+## Prerequisites
+
+- Docker Desktop (Windows/Mac) or Docker Engine 24+ (Linux)
+- Git
+- `curl` or any HTTP client (for testing)
+
+## Architecture
+
+The platform runs as a Docker Compose stack with 6 services:
+
+| Service | Image | Port | Purpose |
+|---------|-------|------|---------|
+| **traefik** | traefik:v3 | 80, 443 | Reverse proxy, TLS, routing |
+| **postgres** | postgres:16-alpine | 5432* | Platform database + Logto database |
+| **logto** | ghcr.io/logto-io/logto | 3001*, 3002* | Identity provider (OIDC) |
+| **cameleer-saas** | cameleer-saas:latest | 8080* | SaaS API server |
+| **cameleer3-server** | cameleer3-server:latest | 8081 | Observability backend |
+| **clickhouse** | clickhouse-server:latest | 8123* | Trace/metrics/log storage |
+
+*Ports exposed to host only with `docker-compose.dev.yml` overlay.
+
+## Installation
+
+### 1. Environment Configuration
+
+```bash
+cp .env.example .env
+```
+
+Edit `.env` and set at minimum:
+
+```bash
+# Change in production
+POSTGRES_PASSWORD=<strong-password>
+CAMELEER_AUTH_TOKEN=<random-string-for-agent-bootstrap>
+CAMELEER_TENANT_SLUG=<your-tenant-slug>   # e.g., "acme" — tags all observability data
+
+# Logto M2M credentials (get from Logto admin console after first boot)
+LOGTO_M2M_CLIENT_ID=
+LOGTO_M2M_CLIENT_SECRET=
+```
+
+### 2. Ed25519 Keys
+
+The platform uses Ed25519 keys for license signing and machine token verification.
+
+```bash
+mkdir -p keys
+ssh-keygen -t ed25519 -f keys/ed25519 -N ""
+mv keys/ed25519 keys/ed25519.key
+```
+
+This creates `keys/ed25519.key` (private) and `keys/ed25519.pub` (public). The keys directory is mounted read-only into the cameleer-saas container.
+
+If no key files are configured, the platform generates ephemeral keys on startup (suitable for development only -- keys change on every restart).
+
+### 3. Start the Stack
+
+**Development** (ports exposed for direct access):
+```bash
+docker compose -f docker-compose.yml -f docker-compose.dev.yml up -d
+```
+
+**Production** (traffic routed through Traefik only):
+```bash
+docker compose up -d
+```
+
+### 4. Verify Services
+
+```bash
+# Health check
+curl http://localhost:8080/actuator/health
+
+# Check all containers are running
+docker compose ps
+```
+
+## Bootstrapping
+
+### First-Time Logto Setup
+
+On first boot, Logto seeds its database automatically. Access the admin console to configure it:
+
+1. Open http://localhost:3002 (Logto admin console)
+2. Complete the initial setup wizard
+3. Create a **Machine-to-Machine** application:
+   - Go to Applications > Create Application > Machine-to-Machine
+   - Note the **App ID** and **App Secret**
+   - Assign the **Logto Management API** resource with all scopes
+4. Update `.env`:
+   ```
+   LOGTO_M2M_CLIENT_ID=<app-id>
+   LOGTO_M2M_CLIENT_SECRET=<app-secret>
+   ```
+5. Restart cameleer-saas: `docker compose restart cameleer-saas`
+
+### Create Your First Tenant
+
+With a Logto user token (obtained via OIDC login flow):
+
+```bash
+TOKEN="<your-logto-jwt>"
+
+# Create tenant
+curl -X POST http://localhost:8080/api/tenants \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"name": "My Company", "slug": "my-company", "tier": "MID"}'
+
+# A "default" environment is auto-created with the tenant
+```
+
+### Generate a License
+
+```bash
+TENANT_ID="<uuid-from-above>"
+
+curl -X POST "http://localhost:8080/api/tenants/$TENANT_ID/license" \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+### Deploy a Camel Application
+
+```bash
+# List environments
+curl "http://localhost:8080/api/tenants/$TENANT_ID/environments" \
+  -H "Authorization: Bearer $TOKEN"
+
+ENV_ID="<default-environment-uuid>"
+
+# Upload JAR and create app
+curl -X POST "http://localhost:8080/api/environments/$ENV_ID/apps" \
+  -H "Authorization: Bearer $TOKEN" \
+  -F 'metadata={"slug":"order-service","displayName":"Order Service"};type=application/json' \
+  -F "file=@/path/to/your-camel-app.jar"
+
+APP_ID="<app-uuid-from-response>"
+
+# Deploy (async -- returns 202 with deployment ID)
+curl -X POST "http://localhost:8080/api/apps/$APP_ID/deploy" \
+  -H "Authorization: Bearer $TOKEN"
+
+DEPLOYMENT_ID="<deployment-uuid>"
+
+# Poll deployment status
+curl "http://localhost:8080/api/apps/$APP_ID/deployments/$DEPLOYMENT_ID" \
+  -H "Authorization: Bearer $TOKEN"
+# Status transitions: BUILDING -> STARTING -> RUNNING (or FAILED)
+
+# View container logs
+curl "http://localhost:8080/api/apps/$APP_ID/logs?limit=50" \
+  -H "Authorization: Bearer $TOKEN"
+
+# Stop the app
+curl -X POST "http://localhost:8080/api/apps/$APP_ID/stop" \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+### Enable Inbound HTTP Routing
+
+If your Camel app exposes a REST endpoint, you can make it reachable from outside the stack:
+
+```bash
+# Set the port your app listens on (e.g., 8080 for Spring Boot)
+curl -X PATCH "http://localhost:8080/api/environments/$ENV_ID/apps/$APP_ID/routing" \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"exposedPort": 8080}'
+```
+
+Your app is now reachable at `http://{app-slug}.{env-slug}.{tenant-slug}.{domain}` (e.g., `http://order-service.default.my-company.localhost`). Traefik routes traffic automatically.
+
+To disable routing, set `exposedPort` to `null`.
+
+### View the Observability Dashboard
+
+The cameleer3-server React SPA dashboard is available at:
+
+```
+http://localhost/dashboard
+```
+
+This shows execution traces, route topology graphs, metrics, and logs for all deployed apps. Authentication is required (Logto OIDC token via forward-auth).
+
+### Check Agent & Observability Status
+
+```bash
+# Is the agent registered with cameleer3-server?
+curl "http://localhost:8080/api/apps/$APP_ID/agent-status" \
+  -H "Authorization: Bearer $TOKEN"
+# Returns: registered, state (ACTIVE/STALE/DEAD/UNKNOWN), routeIds
+
+# Is the app producing observability data?
+curl "http://localhost:8080/api/apps/$APP_ID/observability-status" \
+  -H "Authorization: Bearer $TOKEN"
+# Returns: hasTraces, lastTraceAt, traceCount24h
+```

+```
+
+## Troubleshooting
+
+**Logto fails to start**: Check that PostgreSQL is healthy first. Logto needs the `logto` database created by `docker/init-databases.sh`. Run `docker compose logs logto` for details.
+
+**cameleer-saas won't start**: Check `docker compose logs cameleer-saas`. Common issues:
+- PostgreSQL not ready (wait for healthcheck)
+- Flyway migration conflict (check for manual schema changes)
+
+**Ephemeral key warnings**: `No Ed25519 key files configured -- generating ephemeral keys (dev mode)` is normal in development. For production, generate keys as described above.
+
+**Container deployment fails**: Check that Docker socket is mounted (`/var/run/docker.sock`) and the `cameleer-runtime-base` image is available. Pull it with: `docker pull gitea.siegeln.net/cameleer/cameleer-runtime-base:latest`

+# Phase 4: Observability Pipeline + Inbound Routing — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Complete the deploy → hit endpoint → see traces loop. Serve the existing cameleer3-server dashboard, add agent connectivity verification, enable optional inbound HTTP routing for customer apps, and wire up observability data health checks.
+
+**Architecture:** Wiring phase — cameleer3-server already has full observability. Phase 4 adds Traefik routing for the dashboard + customer app endpoints, new API endpoints in cameleer-saas for agent-status and observability-status, and configures `CAMELEER_TENANT_ID` on the server.
+
+**Tech Stack:** Spring Boot 3.4.3, docker-java 3.4.1, ClickHouse JDBC, Traefik v3 labels, Spring RestClient

+- [ ] **Step 1: Add labels field to StartContainerRequest**
+
+Replace the current record with:
+
+```java
+package net.siegeln.cameleer.saas.runtime;
+
+import java.util.Map;
+
+public record StartContainerRequest(
+        String imageRef,
+        String containerName,
+        String network,
+        Map<String, String> envVars,
+        long memoryLimitBytes,
+        int cpuShares,
+        int healthCheckPort,
+        Map<String, String> labels
+) {}
+```
+
+- [ ] **Step 2: Apply labels in DockerRuntimeOrchestrator.startContainer**
+
+In the `startContainer` method, after `.withHostConfig(hostConfig)` and before `.withHealthcheck(...)`, add:
+
+```java
+                .withLabels(request.labels() != null ? request.labels() : Map.of())
+```
+
+- [ ] **Step 3: Fix all existing callers of StartContainerRequest**
+
+The `DeploymentService.executeDeploymentAsync` method creates a `StartContainerRequest`. Add `Map.of()` as the labels argument (empty labels for now — routing labels come in Task 5):
+
+Find the existing `new StartContainerRequest(...)` call and add `Map.of()` as the last argument.
+
+- [ ] **Step 4: Verify compilation and run unit tests**

+- Modify: `src/main/resources/application.yml`
+
+- [ ] **Step 1: Add domain property to RuntimeConfig**
+
+Add field and getter:
+
+```java
+    @Value("${cameleer.runtime.domain:localhost}")
+    private String domain;
+
+    public String getDomain() { return domain; }
+```
+
+- [ ] **Step 2: Add domain to application.yml**
+
+In the `cameleer.runtime` section, add:
+
+```yaml
+    domain: ${DOMAIN:localhost}
+```
+
+- [ ] **Step 3: Update AppResponse to include exposedPort and routeUrl**
+
+Replace the record:
+
+```java
+package net.siegeln.cameleer.saas.app.dto;
+
+import java.time.Instant;
+import java.util.UUID;
+
+public record AppResponse(
+        UUID id,
+        UUID environmentId,
+        String slug,
+        String displayName,
+        String jarOriginalFilename,
+        Long jarSizeBytes,
+        String jarChecksum,
+        Integer exposedPort,
+        String routeUrl,
+        UUID currentDeploymentId,
+        UUID previousDeploymentId,
+        Instant createdAt,
+        Instant updatedAt
+) {}
+```
+
+- [ ] **Step 4: Create UpdateRoutingRequest**
+
+```java
+package net.siegeln.cameleer.saas.observability.dto;
+
+public record UpdateRoutingRequest(
+        Integer exposedPort
+) {}
+```
+
+- [ ] **Step 5: Add updateRouting method to AppService**
+
+```java
+    public AppEntity updateRouting(UUID appId, Integer exposedPort, UUID actorId) {
+        var app = appRepository.findById(appId)
+                .orElseThrow(() -> new IllegalArgumentException("App not found"));
+        app.setExposedPort(exposedPort);
+        return appRepository.save(app);
+    }
+```
+
+- [ ] **Step 6: Update AppController — add PATCH routing endpoint and update toResponse**
+
+Add the endpoint:
+
+```java
+    @PatchMapping("/{appId}/routing")
+    public ResponseEntity<AppResponse> updateRouting(
+            @PathVariable UUID environmentId,
+            @PathVariable UUID appId,
+            @RequestBody UpdateRoutingRequest request,
+            Authentication authentication) {
+        try {
+            var actorId = resolveActorId(authentication);
+            var app = appService.updateRouting(appId, request.exposedPort(), actorId);
+            var env = environmentService.getById(app.getEnvironmentId()).orElse(null);
+            return ResponseEntity.ok(toResponse(app, env));
+        } catch (IllegalArgumentException e) {
+            return ResponseEntity.notFound().build();
+        }
+    }
+```
+
+This requires adding `EnvironmentService` and `RuntimeConfig` as constructor dependencies to `AppController`. Update the constructor.
+
+Update `toResponse` to accept the environment and compute the route URL:
+
+```java
+    private AppResponse toResponse(AppEntity app, EnvironmentEntity env) {
+        String routeUrl = null;
+        if (app.getExposedPort() != null && env != null) {
+            var tenant = tenantRepository.findById(env.getTenantId()).orElse(null);
+            if (tenant != null) {
+                routeUrl = "http://" + app.getSlug() + "." + env.getSlug() + "."
+                        + tenant.getSlug() + "." + runtimeConfig.getDomain();
+            }
+        }
+        return new AppResponse(
+                app.getId(), app.getEnvironmentId(), app.getSlug(), app.getDisplayName(),
+                app.getJarOriginalFilename(), app.getJarSizeBytes(), app.getJarChecksum(),
+                app.getExposedPort(), routeUrl,
+                app.getCurrentDeploymentId(), app.getPreviousDeploymentId(),
+                app.getCreatedAt(), app.getUpdatedAt());
+    }
+```
+
+This requires adding `TenantRepository` as a constructor dependency too. Update the existing `toResponse(AppEntity)` calls in other methods to pass the environment — look up the environment from the `environmentId` path variable or from `environmentService`.
+
+For the list/get/create endpoints that already have `environmentId` in the path, look up the environment once and pass it.

+**Files:**
+- Modify: `src/main/java/net/siegeln/cameleer/saas/deployment/DeploymentService.java`
+
+- [ ] **Step 1: Build Traefik labels when app has exposedPort**
+
+In `executeDeploymentAsync`, after building the `envVars` map and before creating `startRequest`, add label computation:
+
+```java
+            // Build Traefik labels for inbound routing
+            var labels = new java.util.HashMap<String, String>();
+            if (app.getExposedPort() != null) {
+                labels.put("traefik.enable", "true");
+                labels.put("traefik.http.routers." + containerName + ".rule",
+                        "Host(`" + app.getSlug() + "." + env.getSlug() + "."
+                                + tenant.getSlug() + "." + runtimeConfig.getDomain() + "`)");
+                labels.put("traefik.http.services." + containerName + ".loadbalancer.server.port",
+                        String.valueOf(app.getExposedPort()));
+            }
+```
+
+Then pass `labels` to the `StartContainerRequest` constructor (replacing the `Map.of()` added in Task 2).

+# Phase 3: Runtime Orchestration + Environments
+
+**Date:** 2026-04-04
+**Status:** Draft
+**Depends on:** Phase 2 (Tenants + Identity + Licensing)
+**Gitea issue:** #26
+
+## Context
+
+Phase 2 delivered multi-tenancy, identity (Logto OIDC), and license management. The platform can create tenants and issue licenses, but there is nothing to run yet. Phase 3 is the core product differentiator: customers upload a Camel JAR, the platform builds an immutable container image with the cameleer3 agent auto-injected, and deploys it to a logical environment. This is "managed Camel runtime" — similar to Coolify or MuleSoft CloudHub, but purpose-built for Apache Camel with deep observability.
+
+Docker-first. The `KubernetesRuntimeOrchestrator` is deferred to Phase 5.
+
+**Single-node constraint:** Because Phase 3 builds images locally via Docker socket (no registry push), the cameleer-saas control plane and the Docker daemon must reside on the same host. This is inherent to the single-tenant Docker Compose stack and is acceptable for that target. In K8s mode (Phase 5), images are built via Kaniko and pushed to a registry, removing this constraint.
+
+## Key Decisions
+
+| Decision | Choice | Rationale |
+|----------|--------|-----------|
+| JAR delivery | Direct HTTP upload (multipart) | Simplest path. Git-based and image-ref options can be added later. |
+| Agent JAR source | Bundled in `cameleer-runtime-base` image | Version-locked to platform release. Updated by rebuilding the platform image with the new agent version. No runtime network dependency. |
+| Build speed | Pre-built base image + single-layer customer add | Customer image build is `FROM base` + `COPY app.jar`. ~1-3 seconds. |
+| Deployment model | Async with polling | Image builds are inherently slow. Deploy returns immediately with deployment ID. Client polls for status. |
+| Entity hierarchy | Environment → App → Deployment | User thinks "I'm in dev, deploy my app." Environment is the workspace context. |
+| Environment provisioning | Hybrid auto + manual | Every tenant gets a `default` environment on creation. Additional environments created manually, tier limit enforced. |
+| Cross-environment isolation | Logical (not network) | Docker single-tenant mode — customer owns the stack. Data separated by `environmentId` in cameleer3-server. Network isolation is a K8s Phase 5 concern. |
+| Container networking | Shared `cameleer` bridge network | Customer containers join the existing network. Agent reaches cameleer3-server at `http://cameleer3-server:8081`. |
+| Container naming | `{tenant-slug}-{env-slug}-{app-slug}` | Human-readable, unique, identifies tenant+environment+app at a glance. |
+| Bootstrap tokens | Shared `CAMELEER_AUTH_TOKEN` from cameleer3-server config | Platform reads the existing token and injects it into customer containers. Environment separation via agent `environmentId` claim, not token. Per-environment tokens deferred to K8s Phase 5. |
+| Health checking | Agent health endpoint (port 9464) | Guaranteed to exist, no user config needed. User-defined health endpoints deferred. |
+| Inbound HTTP routing | Not in Phase 3 | Most Camel apps are consumers (queues, polls), not servers. Traefik routing for customer apps deferred to Phase 4/4.5. |
+| Container logs | Captured via docker-java, written to ClickHouse | Unified log query surface from day 1. Same pattern future app logs will use. |
+| Resource constraints | cgroups via docker-java `mem_limit` + `cpu_shares` | Protect the control plane from noisy neighbors. Tier-based defaults. Even in single-tenant Docker mode, a runaway Camel app shouldn't starve Traefik/Postgres/Logto. |
+| Orchestrator metadata | JSONB field on deployment entity | Docker stores `containerId`. K8s (Phase 5) stores `namespace`, `deploymentName`, `gitCommit`. Same table, different orchestrator. |
+
+## Data Model
+
+### Environment Entity
+
+```sql
+CREATE TABLE environments (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    tenant_id UUID NOT NULL REFERENCES tenants(id) ON DELETE CASCADE,
+    slug VARCHAR(100) NOT NULL,
+    display_name VARCHAR(255) NOT NULL,
+    bootstrap_token TEXT NOT NULL,
+    status VARCHAR(20) NOT NULL DEFAULT 'ACTIVE',
+    created_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
+    updated_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
+    UNIQUE(tenant_id, slug)
+);
+
+CREATE INDEX idx_environments_tenant_id ON environments(tenant_id);
+```
+
+- `slug` — URL-safe, immutable, unique per tenant. Auto-created environment gets slug `default`.
+- `display_name` — User-editable. Auto-created environment gets `Default`.
+- `bootstrap_token` — The `CAMELEER_AUTH_TOKEN` value used for customer containers in this environment. In Docker mode, all environments share the same value (read from platform config). In K8s mode (Phase 5), can be unique per environment.
+- `status` — `ACTIVE` or `SUSPENDED`.
+
+### App Entity
+
+```sql
+CREATE TABLE apps (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    environment_id UUID NOT NULL REFERENCES environments(id) ON DELETE CASCADE,
+    slug VARCHAR(100) NOT NULL,
+    display_name VARCHAR(255) NOT NULL,
+    jar_storage_path VARCHAR(500),
+    jar_checksum VARCHAR(64),
+    jar_original_filename VARCHAR(255),
+    jar_size_bytes BIGINT,
+    current_deployment_id UUID,
+    previous_deployment_id UUID,
+    created_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
+    updated_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
+    UNIQUE(environment_id, slug)
+);
+
+CREATE INDEX idx_apps_environment_id ON apps(environment_id);
+```
+
+- `slug` — URL-safe, immutable, unique per environment.
+- `jar_storage_path` — Relative path to uploaded JAR (e.g., `tenants/{tenant-slug}/envs/{env-slug}/apps/{app-slug}/app.jar`). Relative to the configured storage root (`cameleer.runtime.jar-storage-path`). Makes it easy to migrate the storage volume to a different mount point or cloud provider.
+- `jar_checksum` — SHA-256 hex digest of the uploaded JAR.
+- `current_deployment_id` — Points to the active deployment. Nullable (app created but never deployed).
+- `previous_deployment_id` — Points to the last known good deployment. When a new deploy succeeds, `current` becomes the new one and `previous` becomes the old `current`. When a deploy fails, `current` stays as the failed one but `previous` still points to the last good version, enabling a rollback button.
+
+### Deployment Entity
+
+```sql
+CREATE TABLE deployments (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    app_id UUID NOT NULL REFERENCES apps(id) ON DELETE CASCADE,
+    version INTEGER NOT NULL,
+    image_ref VARCHAR(500) NOT NULL,
+    desired_status VARCHAR(20) NOT NULL DEFAULT 'RUNNING',
+    observed_status VARCHAR(20) NOT NULL DEFAULT 'BUILDING',
+    orchestrator_metadata JSONB DEFAULT '{}',
+    error_message TEXT,
+    deployed_at TIMESTAMPTZ,
+    stopped_at TIMESTAMPTZ,
+    created_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
+    UNIQUE(app_id, version)
+);
+
+CREATE INDEX idx_deployments_app_id ON deployments(app_id);
+```
+
+- `version` — Sequential per app (1, 2, 3...). Incremented on each deploy.
+- `image_ref` — Docker image reference, e.g., `cameleer-runtime-{tenant}-{app}:v3`.
+- `desired_status` — What the user wants: `RUNNING`, `STOPPED`.
+- `observed_status` — What the platform sees: `BUILDING`, `STARTING`, `RUNNING`, `FAILED`, `STOPPED`.
+- `orchestrator_metadata` — Docker mode: `{"containerId": "abc123"}`. K8s mode (Phase 5): `{"namespace": "...", "deploymentName": "...", "gitCommit": "..."}`.
+- `error_message` — Populated when `observed_status` is `FAILED`. Build error, startup crash, etc.
+
+## Component Architecture
+
+### RuntimeOrchestrator Interface
+
+```java
+public interface RuntimeOrchestrator {
+    String buildImage(BuildImageRequest request);
+    void startContainer(StartContainerRequest request);
+    void stopContainer(String containerId);
+    void removeContainer(String containerId);
+    ContainerStatus getContainerStatus(String containerId);
+    void streamLogs(String containerId, LogConsumer consumer);
+}
+```
+
+- Single interface, implemented by `DockerRuntimeOrchestrator` (Phase 3) and `KubernetesRuntimeOrchestrator` (Phase 5).
+- Injected via Spring `@Profile` or `@ConditionalOnProperty`.
+- Request objects carry all context (image name, env vars, network, labels, etc.).
+
+### DockerRuntimeOrchestrator
+
+Uses `com.github.docker-java:docker-java` library. Connects via Docker socket (`/var/run/docker.sock`).
+
+**buildImage:**
+1. Creates a temporary build context directory
+2. Writes a Dockerfile:
+   ```dockerfile
+   FROM cameleer-runtime-base:{platform-version}
+   COPY app.jar /app/app.jar
+   ```
+3. Copies the customer JAR as `app.jar`
+4. Calls `docker build` via docker-java
+5. Tags as `cameleer-runtime-{tenant-slug}-{app-slug}:v{version}`
+6. Returns the image reference
+
+**startContainer:**
+1. Creates container with:
+   - Image: the built image reference
+   - Name: `{tenant-slug}-{env-slug}-{app-slug}`
+   - Network: `cameleer` (the platform bridge network)
+   - Environment variables:
+     - `CAMELEER_AUTH_TOKEN={bootstrap-token}`
+     - `CAMELEER_EXPORT_TYPE=HTTP`
+     - `CAMELEER_EXPORT_ENDPOINT=http://cameleer3-server:8081`
+     - `CAMELEER_APPLICATION_ID={app-slug}`
+     - `CAMELEER_ENVIRONMENT_ID={env-slug}`
+     - `CAMELEER_DISPLAY_NAME={tenant-slug}-{env-slug}-{app-slug}`
+   - Resource constraints (cgroups):
+     - `memory` / `memorySwap` — hard memory limit per container
+     - `cpuShares` — relative CPU weight (default 512)
+     - Defaults configurable via `cameleer.runtime.container-memory-limit` (default `512m`) and `cameleer.runtime.container-cpu-shares` (default `512`)
+     - Protects the control plane (Traefik, Postgres, Logto, cameleer-saas) from noisy neighbor Camel apps
+   - Health check: HTTP GET to agent health port 9464
+2. Starts container
+3. Returns container ID
+
+**streamLogs:**
+- Attaches to container stdout/stderr via docker-java `LogContainerCmd`
+- Passes log lines to a `LogConsumer` callback (for ClickHouse ingestion)
+
+### cameleer-runtime-base Image
+
+A pre-built Docker image containing everything except the customer JAR:
+
+```dockerfile
+FROM eclipse-temurin:21-jre-alpine
+WORKDIR /app
+
+COPY cameleer3-agent-{version}-shaded.jar /app/agent.jar
+
+ENTRYPOINT exec java \
+  -Dcameleer.export.type=${CAMELEER_EXPORT_TYPE:-HTTP} \
+  -Dcameleer.export.endpoint=${CAMELEER_EXPORT_ENDPOINT} \
+  -Dcameleer.agent.name=${HOSTNAME} \
+  -Dcameleer.agent.application=${CAMELEER_APPLICATION_ID:-default} \
+  -Dcameleer.agent.environment=${CAMELEER_ENVIRONMENT_ID:-default} \
+  -Dcameleer.routeControl.enabled=${CAMELEER_ROUTE_CONTROL_ENABLED:-false} \
+  -Dcameleer.replay.enabled=${CAMELEER_REPLAY_ENABLED:-false} \
+  -Dcameleer.health.enabled=true \
+  -Dcameleer.health.port=9464 \
+  -javaagent:/app/agent.jar \
+  -jar /app/app.jar
+```
+
+- Built as part of the CI pipeline for cameleer-saas.
+- Published to Gitea registry: `gitea.siegeln.net/cameleer/cameleer-runtime-base:{version}`.
+- Version tracks the platform version + agent version (e.g., `0.2.0` includes agent `1.0-SNAPSHOT`).
+- Updating the agent JAR = rebuild this image with the new agent version → rebuild cameleer-saas image → all new deployments use the new agent.
+
+### JAR Upload
+
+- `POST /api/environments/{eid}/apps` with multipart file
+- Validation:
+  - File extension: `.jar`
+  - Max size: 200 MB (configurable via `cameleer.runtime.max-jar-size`)
+  - SHA-256 checksum computed and stored
+- Storage: relative path `tenants/{tenant-slug}/envs/{env-slug}/apps/{app-slug}/app.jar` under the configured storage root (`cameleer.runtime.jar-storage-path`, default `/data/jars`)
+  - Docker volume `jardata` mounted into cameleer-saas container
+  - Database stores the relative path only — decoupled from mount point
+- JAR is overwritten on re-upload (new deploy uses new JAR)
+
+### Async Deployment Pipeline
+
+1. **API receives deploy request** → creates `Deployment` entity with `observed_status=BUILDING` → returns deployment ID (HTTP 202 Accepted)
+2. **Background thread** (Spring `@Async` with a bounded thread pool):
+   a. Calls `orchestrator.buildImage(...)` → updates `observed_status=STARTING`
+   b. Calls `orchestrator.startContainer(...)` → updates `observed_status=STARTING`
+   c. Polls agent health endpoint (port 9464) with timeout → updates to `RUNNING` or `FAILED`
+   d. On any failure → updates `observed_status=FAILED`, `error_message=...`
+3. **Client polls** `GET /api/apps/{aid}/deployments/{did}` for status updates
+4. **On success:** set `previous_deployment_id = old current_deployment_id`, then `current_deployment_id = new deployment`. Stop and remove the old container.
+5. **On failure:** `current_deployment_id` is set to the failed deployment (so status is visible), `previous_deployment_id` still points to the last known good version. Enables rollback.
+
+### Container Logs → ClickHouse
+
+- When a container starts, platform attaches a log consumer via `orchestrator.streamLogs()`
+- Log consumer batches lines and writes to ClickHouse table:
+
+```sql
+CREATE TABLE IF NOT EXISTS container_logs (
+    tenant_id UUID,
+    environment_id UUID,
+    app_id UUID,
+    deployment_id UUID,
+    timestamp DateTime64(3),
+    stream String,  -- 'stdout' or 'stderr'
+    message String
+) ENGINE = MergeTree()
+ORDER BY (tenant_id, environment_id, app_id, timestamp);
+```
+
+- Logs retrieved via `GET /api/apps/{aid}/logs?since=...&limit=...` which queries ClickHouse
+- ClickHouse TTL can enforce retention based on license `retention_days` limit (future enhancement)
+
+### Bootstrap Token Handling
+
+In Docker single-tenant mode, all environments share the single cameleer3-server instance and its single `CAMELEER_AUTH_TOKEN`. The platform reads this token from its own configuration (`cameleer.runtime.bootstrap-token` / `CAMELEER_AUTH_TOKEN` env var) and injects it into every customer container. No changes to cameleer3-server are needed.
+
+Environment-level data separation happens at the agent registration level — the agent sends its `environmentId` claim when it registers, and cameleer3-server uses that to scope all data. The bootstrap token is the same across environments in a Docker stack.
+
+The `bootstrap_token` column on the environment entity stores the token value used for that environment's containers. In Docker mode this is the same shared value for all environments. In K8s mode (Phase 5), each environment could have its own cameleer3-server instance with a unique token, enabling true per-environment token isolation.

+
+## Tier Enforcement
+
+| Tier | max_environments | max_agents (apps) |
+|------|-----------------|-------------------|
+| LOW | 1 | 3 |
+| MID | 2 | 10 |
+| HIGH | unlimited (-1) | 50 |
+| BUSINESS | unlimited (-1) | unlimited (-1) |
+
+- `max_environments` enforced on `POST /api/tenants/{tid}/environments`. The auto-created `default` environment counts toward the limit.
+- `max_agents` enforced on `POST /api/environments/{eid}/apps`. Count is total apps across all environments in the tenant.
+
+## Docker Compose Changes
+
+The cameleer-saas service needs:
+- Docker socket mount: `/var/run/docker.sock:/var/run/docker.sock` (already present in docker-compose.yml)
+- JAR storage volume: `jardata:/data/jars`
+- `cameleer-runtime-base` image must be available (pre-pulled or built locally)
+
+The cameleer3-server `CAMELEER_AUTH_TOKEN` is read by cameleer-saas from shared environment config and injected into customer containers.
+
+New volume in docker-compose.yml:
+```yaml
+volumes:
+  jardata:

+## Verification Plan
+
+1. Upload a sample Camel JAR via `POST /api/environments/{eid}/apps`
+2. Deploy via `POST /api/apps/{aid}/deploy` — returns 202 with deployment ID
+3. Poll `GET /api/apps/{aid}/deployments/{did}` — status transitions: `BUILDING` → `STARTING` → `RUNNING`
+4. Container visible in `docker ps` as `{tenant}-{env}-{app}`
+5. Container is on the `cameleer` network
+6. cameleer3 agent registers with cameleer3-server (visible in server logs)
+7. Agent health endpoint responds on port 9464
+8. Container logs appear in ClickHouse `container_logs` table
+9. `GET /api/apps/{aid}/logs` returns log entries
+10. `POST /api/apps/{aid}/stop` stops the container, status becomes `STOPPED`
+11. `POST /api/apps/{aid}/restart` restarts with same image
+12. Re-upload JAR + redeploy creates deployment v2, stops v1
+13. Tier limits enforced: LOW tenant cannot create more than 1 environment or 3 apps
+14. Default environment auto-created on tenant provisioning

+# Phase 4: Observability Pipeline + Inbound Routing
+
+**Date:** 2026-04-04
+**Status:** Draft
+**Depends on:** Phase 3 (Runtime Orchestration + Environments)
+**Gitea issue:** #28
+
+## Context
+
+Phase 3 delivered the managed Camel runtime: customers upload a JAR, the platform builds a container with the cameleer3 agent injected, and deploys it. The agent connects to cameleer3-server and sends traces, metrics, diagrams, and logs to ClickHouse. But there is no way for the user to see this data yet, and customer apps that expose HTTP endpoints are not reachable.
+
+Phase 4 completes the loop: deploy an app, hit its endpoint, see the traces in the dashboard.
+
+cameleer3-server already has the complete observability stack — ClickHouse schemas with `tenant_id` partitioning, full search/stats/diagram/log REST APIs, and a React SPA dashboard. Phase 4 is a **wiring phase**, not a build-from-scratch phase.
+
+## Key Decisions
+
+| Decision | Choice | Rationale |
+|----------|--------|-----------|
+| Observability UI | Serve existing cameleer3-server React SPA via Traefik | Already built. SaaS management UI is Phase 9 — observability UI is not SaaS-specific. |
+| API access | Traefik routes directly to cameleer3-server with forward-auth | No proxy layer needed. Forward-auth validates user, injects headers. Server API works as-is. |
+| Server changes | None | Single-tenant Docker mode works out of the box. `CAMELEER_TENANT_ID` env var already supported. |
+| Agent changes | None | Agent already sends `applicationId`, `environmentId`, connects to `CAMELEER_EXPORT_ENDPOINT`. |
+| Tenant ID | Set `CAMELEER_TENANT_ID` to tenant slug in Docker Compose | Tags ClickHouse data with the real tenant identity from day one. Avoids `'default'` → real-id migration later. |
+| Inbound routing | Optional `exposedPort` on deployment, Traefik labels on customer containers | Thin feature. `{app}.{env}.{tenant}.{domain}` routing via Traefik Host rule. |
+
+## What's Already Working (Phase 3)
+
+- Customer containers on the `cameleer` bridge network
+- Agent configured: `CAMELEER_AUTH_TOKEN`, `CAMELEER_EXPORT_ENDPOINT=http://cameleer3-server:8081`, `CAMELEER_APPLICATION_ID`, `CAMELEER_ENVIRONMENT_ID`
+- cameleer3-server writes traces/metrics/diagrams/logs to ClickHouse
+- Traefik routes `/observe/*` to cameleer3-server with forward-auth middleware
+- Forward-auth endpoint at `/auth/verify` validates JWT, returns `X-Tenant-Id`, `X-User-Id`, `X-User-Email` headers
+
+## Component 1: Serve cameleer3-server Dashboard
+
+### Traefik Routing
+
+Add Traefik labels to the cameleer3-server service in `docker-compose.yml` to serve the React SPA:
+
+```yaml
+# Existing (Phase 3):
+- traefik.http.routers.observe.rule=PathPrefix(`/observe`)
+- traefik.http.routers.observe.middlewares=forward-auth
+
+# New (Phase 4):
+- traefik.http.routers.dashboard.rule=PathPrefix(`/dashboard`)
+- traefik.http.routers.dashboard.middlewares=forward-auth
+- traefik.http.services.dashboard.loadbalancer.server.port=8080
+```
+
+The cameleer3-server SPA is served from its own embedded web server. The SPA already calls the server's API endpoints at relative paths — the existing `/observe/*` Traefik route handles those requests with forward-auth.
+
+**Note:** If the cameleer3-server SPA expects to be served from `/` rather than `/dashboard`, a Traefik StripPrefix middleware may be needed:
+
+```yaml
+- traefik.http.middlewares.dashboard-strip.stripprefix.prefixes=/dashboard
+- traefik.http.routers.dashboard.middlewares=forward-auth,dashboard-strip
+```
+
+This depends on how the cameleer3-server SPA is configured (base path). To be verified during implementation.
+
+### CAMELEER_TENANT_ID Configuration
+
+Set `CAMELEER_TENANT_ID` on the cameleer3-server service so all ingested data is tagged with the real tenant slug:
+
+```yaml
+cameleer3-server:
+  environment:
+    CAMELEER_TENANT_ID: ${CAMELEER_TENANT_SLUG:-default}
+```
+
+In the Docker single-tenant stack, this is set once during initial setup (e.g., `CAMELEER_TENANT_SLUG=acme` in `.env`). All ClickHouse data is then partitioned under this tenant ID.
+
+Add `CAMELEER_TENANT_SLUG` to `.env.example`.
+
+## Component 2: Agent Connectivity Verification
+
+New endpoint in cameleer-saas to check whether a deployed app's agent has successfully registered with cameleer3-server and is sending data.
+
+### API
+
+```
+GET /api/apps/{appId}/agent-status
+Returns: 200 + AgentStatusResponse
+```
+
+### AgentStatusResponse
+
+```java
+public record AgentStatusResponse(
+    boolean registered,
+    String state,           // ACTIVE, STALE, DEAD, UNKNOWN
+    Instant lastHeartbeat,
+    List<String> routeIds,
+    String applicationId,
+    String environmentId
+) {}
+```
+
+### Implementation
+
+`AgentStatusService` in cameleer-saas calls cameleer3-server's agent registry API:
+
+```
+GET http://cameleer3-server:8081/api/v1/agents
+```
+
+This returns the list of registered agents. The service filters by `applicationId` matching the app's slug and `environmentId` matching the environment's slug.
+
+If the cameleer3-server doesn't expose a public agent listing endpoint, the alternative is to query ClickHouse directly for recent data:
+
+```sql
+SELECT max(timestamp) as last_seen
+FROM container_logs
+WHERE app_id = ? AND deployment_id = ?
+LIMIT 1
+```
+
+The preferred approach is the agent registry API. If it requires authentication, cameleer-saas can use the shared `CAMELEER_AUTH_TOKEN` as a machine token.
+
+### Integration with Deployment Status
+
+After a deployment reaches `RUNNING` status (container healthy), the platform can poll agent-status to confirm the agent has registered. This could be surfaced as a sub-status:
+
+- `RUNNING` — container is healthy
+- `RUNNING_CONNECTED` — container healthy + agent registered with server
+- `RUNNING_DISCONNECTED` — container healthy but agent not yet registered (timeout: 30s)
+
+This is a nice-to-have enhancement on top of the basic agent-status endpoint.
+
+## Component 3: Inbound HTTP Routing for Customer Apps
+
+### Data Model
+
+Add `exposed_port` column to the `apps` table:
+
+```sql
+ALTER TABLE apps ADD COLUMN exposed_port INTEGER;
+```
+
+This is the port the customer's Camel app listens on inside the container (e.g., 8080 for a Spring Boot REST app). When set, Traefik routes external traffic to this port.
+
+### API
+
+```
+PATCH /api/apps/{appId}/routing
+Body: { "exposedPort": 8080 }    // or null to disable routing
+Returns: 200 + AppResponse
+```
+
+The routable URL is computed and included in `AppResponse`:
+
+```java
+// In AppResponse, add:
+String routeUrl    // e.g., "http://order-svc.default.acme.localhost" or null if no routing
+```
+
+### URL Pattern
+
+```
+{app-slug}.{env-slug}.{tenant-slug}.{domain}
+```
+
+Example: `order-svc.default.acme.localhost`
+
+The `{domain}` comes from the `DOMAIN` env var (already in `.env.example`).
+
+### DockerRuntimeOrchestrator Changes
+
+When starting a container for an app that has `exposedPort` set, add Traefik labels:
+
+```java
+var labels = new HashMap<String, String>();
+labels.put("traefik.enable", "true");
+labels.put("traefik.http.routers." + containerName + ".rule",
+    "Host(`" + app.getSlug() + "." + env.getSlug() + "." + tenant.getSlug() + "." + domain + "`)");
+labels.put("traefik.http.services." + containerName + ".loadbalancer.server.port",
+    String.valueOf(app.getExposedPort()));
+```
+
+These labels are set on the Docker container via docker-java's `withLabels()` on the `CreateContainerCmd`.
+
+Traefik auto-discovers labeled containers on the `cameleer` network (already configured in `traefik.yml` with `exposedByDefault: false`).
+
+### StartContainerRequest Changes
+
+Add optional fields to `StartContainerRequest`:
+
+```java
+public record StartContainerRequest(
+    String imageRef,
+    String containerName,
+    String network,
+    Map<String, String> envVars,
+    long memoryLimitBytes,
+    int cpuShares,
+    int healthCheckPort,
+    Map<String, String> labels       // NEW: Traefik routing labels
+) {}
+```
+
+### RuntimeConfig Addition
+
+```yaml
+cameleer:
+  runtime:
+    domain: ${DOMAIN:localhost}
+```
+
+## Component 4: End-to-End Connectivity Health
+
+### Startup Verification
+
+On application startup, cameleer-saas verifies that cameleer3-server is reachable:
+
+```java
+@EventListener(ApplicationReadyEvent.class)
+public void verifyConnectivity() {
+    // HTTP GET http://cameleer3-server:8081/actuator/health
+    // Log result: "cameleer3-server connectivity: OK" or "FAILED: ..."
+}
+```
+
+This is a best-effort check, not a hard dependency. If cameleer3-server is not yet running (e.g., starting up), the SaaS platform still starts. The check is logged for diagnostics.
+
+### ClickHouse Data Verification
+
+Add a lightweight endpoint for checking whether a deployed app is producing observability data:
+
+```
+GET /api/apps/{appId}/observability-status
+Returns: 200 + ObservabilityStatusResponse
+```
+
+```java
+public record ObservabilityStatusResponse(
+    boolean hasTraces,
+    boolean hasMetrics,
+    boolean hasDiagrams,
+    Instant lastTraceAt,
+    long traceCount24h
+) {}
+```
+
+Implementation queries ClickHouse:
+
+```sql
+SELECT
+    count() > 0 as has_traces,
+    max(start_time) as last_trace,
+    count() as trace_count_24h
+FROM executions
+WHERE tenant_id = ? AND application_id = ? AND environment = ?
+  AND start_time > now() - INTERVAL 24 HOUR
+```
+
+This requires cameleer-saas to query ClickHouse directly (the `clickHouseDataSource` bean from Phase 3). The query is scoped by tenant + application + environment.
+
+## Docker Compose Changes
+
+### cameleer3-server labels (add dashboard route)
+
+```yaml
+cameleer3-server:
+  environment:
+    CAMELEER_TENANT_ID: ${CAMELEER_TENANT_SLUG:-default}
+  labels:
+    # Existing:
+    - traefik.enable=true
+    - traefik.http.routers.observe.rule=PathPrefix(`/observe`)
+    - traefik.http.routers.observe.middlewares=forward-auth
+    - traefik.http.services.observe.loadbalancer.server.port=8080
+    # New:
+    - traefik.http.routers.dashboard.rule=PathPrefix(`/dashboard`)
+    - traefik.http.routers.dashboard.middlewares=forward-auth,dashboard-strip
+    - traefik.http.middlewares.dashboard-strip.stripprefix.prefixes=/dashboard
+    - traefik.http.services.dashboard.loadbalancer.server.port=8080
+```
+
+### .env.example addition
+
+```
+CAMELEER_TENANT_SLUG=default
+```
+
+## Database Migration
+
+```sql
+-- V010__add_exposed_port_to_apps.sql
+ALTER TABLE apps ADD COLUMN exposed_port INTEGER;
+```
+
+## New Configuration Properties
+
+```yaml
+cameleer:
+  runtime:
+    domain: ${DOMAIN:localhost}
+```
+
+## Verification Plan
+
+1. Deploy a sample Camel REST app with `exposedPort: 8080`
+2. `curl http://order-svc.default.acme.localhost` hits the Camel app
+3. The Camel route processes the request
+4. cameleer3 agent captures the trace and sends to cameleer3-server
+5. `GET /api/apps/{appId}/agent-status` shows `registered: true, state: ACTIVE`
+6. `GET /api/apps/{appId}/observability-status` shows `hasTraces: true`
+7. Open `http://localhost/dashboard` — cameleer3-server SPA loads
+8. Traces visible in the dashboard for the deployed app
+9. Route topology graph shows the Camel route structure
+10. `CAMELEER_TENANT_ID` is set to the tenant slug in ClickHouse data
+
+## What Phase 4 Does NOT Touch
+
+- No changes to cameleer3-server code (works as-is for single-tenant Docker mode)
+- No changes to the cameleer3 agent
+- No new ClickHouse schemas (cameleer3-server manages its own)
+- No SaaS management UI (Phase 9)
+- No K8s-specific changes (Phase 5)
