# 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

## Task 1: Database Migration + Entity Changes

**Files:**
- Create: `src/main/resources/db/migration/V010__add_exposed_port_to_apps.sql`
- Modify: `src/main/java/net/siegeln/cameleer/saas/app/AppEntity.java`

- [ ] **Step 1: Create migration V010**

```sql
ALTER TABLE apps ADD COLUMN exposed_port INTEGER;
```

- [ ] **Step 2: Add exposedPort field to AppEntity**

Add after `previousDeploymentId` field:

```java
    @Column(name = "exposed_port")
    private Integer exposedPort;
```

Add getter and setter:

```java
    public Integer getExposedPort() { return exposedPort; }
    public void setExposedPort(Integer exposedPort) { this.exposedPort = exposedPort; }
```

- [ ] **Step 3: Verify compilation**

Run: `mvn compile -B -q`

- [ ] **Step 4: Commit**

```bash
git add src/main/resources/db/migration/V010__add_exposed_port_to_apps.sql \
  src/main/java/net/siegeln/cameleer/saas/app/AppEntity.java
git commit -m "feat: add exposed_port column to apps table"
```

---

## Task 2: StartContainerRequest Labels + DockerRuntimeOrchestrator

**Files:**
- Modify: `src/main/java/net/siegeln/cameleer/saas/runtime/StartContainerRequest.java`
- Modify: `src/main/java/net/siegeln/cameleer/saas/runtime/DockerRuntimeOrchestrator.java`

- [ ] **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**

Run: `mvn test -B -Dsurefire.excludes="**/*ControllerTest.java,**/AuditRepositoryTest.java,**/CameleerSaasApplicationTest.java" -q`

- [ ] **Step 5: Commit**

```bash
git add src/main/java/net/siegeln/cameleer/saas/runtime/StartContainerRequest.java \
  src/main/java/net/siegeln/cameleer/saas/runtime/DockerRuntimeOrchestrator.java \
  src/main/java/net/siegeln/cameleer/saas/deployment/DeploymentService.java
git commit -m "feat: add labels support to StartContainerRequest and DockerRuntimeOrchestrator"
```

## Task 3: RuntimeConfig Domain + AppResponse + AppService Routing

**Files:**
- Modify: `src/main/java/net/siegeln/cameleer/saas/runtime/RuntimeConfig.java`
- Modify: `src/main/java/net/siegeln/cameleer/saas/app/dto/AppResponse.java`
- Modify: `src/main/java/net/siegeln/cameleer/saas/app/AppService.java`
- Modify: `src/main/java/net/siegeln/cameleer/saas/app/AppController.java`
- Create: `src/main/java/net/siegeln/cameleer/saas/observability/dto/UpdateRoutingRequest.java`
- 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.

- [ ] **Step 7: Verify compilation**

Run: `mvn compile -B -q`

- [ ] **Step 8: Commit**

```bash
git add src/main/java/net/siegeln/cameleer/saas/runtime/RuntimeConfig.java \
  src/main/java/net/siegeln/cameleer/saas/app/dto/AppResponse.java \

- 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).

Note: The `tenant` variable is already looked up earlier in the method for container naming.

- [ ] **Step 2: Run unit tests**

Run: `mvn test -pl . -Dtest=DeploymentServiceTest -B`
Expected: All tests PASS

- [ ] **Step 3: Commit**

```bash
git add src/main/java/net/siegeln/cameleer/saas/deployment/DeploymentService.java
git commit -m "feat: add Traefik routing labels for customer apps with exposed ports"
```

## Task 6: Connectivity Health Check

**Files:**
- Create: `src/main/java/net/siegeln/cameleer/saas/observability/ConnectivityHealthCheck.java`

- [ ] **Step 1: Create startup connectivity check**

```java
package net.siegeln.cameleer.saas.observability;

import net.siegeln.cameleer.saas.runtime.RuntimeConfig;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.context.event.ApplicationReadyEvent;
import org.springframework.context.event.EventListener;
import org.springframework.stereotype.Component;
import org.springframework.web.client.RestClient;

@Component
public class ConnectivityHealthCheck {

    private static final Logger log = LoggerFactory.getLogger(ConnectivityHealthCheck.class);

    private final RuntimeConfig runtimeConfig;

    public ConnectivityHealthCheck(RuntimeConfig runtimeConfig) {
        this.runtimeConfig = runtimeConfig;
    }

    @EventListener(ApplicationReadyEvent.class)
    public void verifyConnectivity() {
        checkCameleer3Server();
    }

    private void checkCameleer3Server() {
        try {
            var client = RestClient.builder()
                    .baseUrl(runtimeConfig.getCameleer3ServerEndpoint())
                    .build();
            var response = client.get()
                    .uri("/actuator/health")
                    .retrieve()
                    .toBodilessEntity();
            if (response.getStatusCode().is2xxSuccessful()) {
                log.info("cameleer3-server connectivity: OK ({})",
                        runtimeConfig.getCameleer3ServerEndpoint());
            } else {
                log.warn("cameleer3-server connectivity: HTTP {} ({})",
                        response.getStatusCode(), runtimeConfig.getCameleer3ServerEndpoint());
            }
        } catch (Exception e) {
            log.warn("cameleer3-server connectivity: FAILED ({}) - {}",
                    runtimeConfig.getCameleer3ServerEndpoint(), e.getMessage());
        }
    }
}
```

- [ ] **Step 2: Verify compilation**

Run: `mvn compile -B -q`

- [ ] **Step 3: Commit**

```bash
git add src/main/java/net/siegeln/cameleer/saas/observability/ConnectivityHealthCheck.java
git commit -m "feat: add cameleer3-server startup connectivity check"
```

## Task 7: Docker Compose + .env + CI Updates

**Files:**
- Modify: `docker-compose.yml`
- Modify: `.env.example`
- Modify: `.gitea/workflows/ci.yml`

- [ ] **Step 1: Update docker-compose.yml — add dashboard route and CAMELEER_TENANT_ID**

In the `cameleer3-server` service:

Add to environment section:
```yaml
    CAMELEER_TENANT_ID: ${CAMELEER_TENANT_SLUG:-default}
```

Add new Traefik labels (after existing ones):
```yaml
    - 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
```

- [ ] **Step 2: Update .env.example**

Add:
```
CAMELEER_TENANT_SLUG=default
```

- [ ] **Step 3: Update CI excludes**

In `.gitea/workflows/ci.yml`, add `**/AgentStatusControllerTest.java` to the Surefire excludes (if integration test exists).

- [ ] **Step 4: Run all unit tests**

Run: `mvn test -B -Dsurefire.excludes="**/*ControllerTest.java,**/AuditRepositoryTest.java,**/CameleerSaasApplicationTest.java" -q`

- [ ] **Step 5: Commit**

```bash
git add docker-compose.yml .env.example .gitea/workflows/ci.yml
git commit -m "feat: add dashboard Traefik route and CAMELEER_TENANT_ID config"
```

## Task 8: Update HOWTO.md

**Files:**
- Modify: `HOWTO.md`

- [ ] **Step 1: Add observability and routing sections**

After the "Deploy a Camel Application" section, add:

**Observability Dashboard section** — explains how to access the dashboard at `/dashboard`, what data is visible.

**Inbound HTTP Routing section** — explains how to set `exposedPort` on an app and what URL to use.

**Agent Status section** — explains the agent-status and observability-status endpoints.

Update the API Reference table with the new endpoints:
- `GET /api/apps/{aid}/agent-status`
- `GET /api/apps/{aid}/observability-status`
- `PATCH /api/environments/{eid}/apps/{aid}/routing`

Update the .env table to include `CAMELEER_TENANT_SLUG`.

- [ ] **Step 2: Commit**

```bash
git add HOWTO.md
git commit -m "docs: update HOWTO with observability dashboard, routing, and agent status"
```
