# Phase 3: Runtime Orchestration + Environments — 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:** Customers can upload a Camel JAR, the platform builds a container image with cameleer agent auto-injected, and deploys it to a logical environment with full lifecycle management.

**Architecture:** Environment → App → Deployment entity hierarchy. `RuntimeOrchestrator` interface with `DockerRuntimeOrchestrator` (docker-java) implementation. Async deployment pipeline with status polling. Container logs streamed to ClickHouse. Pre-built `cameleer-runtime-base` image for fast (~1-3s) customer image builds.

**Tech Stack:** Spring Boot 3.4.3, docker-java 3.4.1, ClickHouse JDBC 0.7.1, Spring @Async, PostgreSQL, Flyway

Run: `mvn test -pl . -Dtest=EnvironmentServiceTest -B`
Expected: COMPILATION FAILURE (EnvironmentService doesn't exist yet)

- [ ] **Step 3: Implement EnvironmentService**

Note: This requires adding `ENVIRONMENT_CREATE`, `ENVIRONMENT_UPDATE`, and `ENVIRONMENT_DELETE` to `AuditAction.java`. Add them after the existing `TENANT_DELETE` entry:

```java
    ENVIRONMENT_CREATE, ENVIRONMENT_UPDATE, ENVIRONMENT_DELETE,
```

Then create the service:

## Task 6: Auto-create Default Environment on Tenant Provisioning

**Files:**
- Modify: `src/main/java/net/siegeln/cameleer/saas/tenant/TenantService.java`

- [ ] **Step 1: Add EnvironmentService dependency to TenantService**

Add `EnvironmentService` as a constructor parameter and field. In the `create()` method, after saving the tenant and provisioning the Logto org, add:

```java
environmentService.createDefaultForTenant(saved.getId());
```

The constructor should become:
```java
public TenantService(TenantRepository tenantRepository,
                     AuditService auditService,
                     LogtoManagementClient logtoClient,
                     EnvironmentService environmentService) {
    this.tenantRepository = tenantRepository;
    this.auditService = auditService;
    this.logtoClient = logtoClient;
    this.environmentService = environmentService;
}
```

Add the field:
```java
private final EnvironmentService environmentService;
```

- [ ] **Step 2: Run existing tenant tests to ensure nothing broke**

Run: `mvn test -pl . -Dtest=TenantServiceTest -B`
Expected: Tests may fail due to missing constructor arg — update `TenantServiceTest` to mock `EnvironmentService` and pass it.

- [ ] **Step 3: Fix TenantServiceTest**

Add `@Mock private EnvironmentService environmentService;` and pass it in the `setUp()` constructor call. This is the existing test pattern.

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

Run: `mvn test -pl . -Dtest=TenantServiceTest,EnvironmentServiceTest -B`
Expected: All tests PASS

- [ ] **Step 5: Commit**

```bash
git add src/main/java/net/siegeln/cameleer/saas/tenant/TenantService.java \
  src/test/java/net/siegeln/cameleer/saas/tenant/TenantServiceTest.java
git commit -m "feat: auto-create default environment on tenant provisioning"

- Create: `src/main/java/net/siegeln/cameleer/saas/deployment/DeploymentEntity.java`
- Create: `src/main/java/net/siegeln/cameleer/saas/deployment/DeploymentRepository.java`

- [ ] **Step 1: Create enums**

`DesiredStatus.java`:
```java
package net.siegeln.cameleer.saas.deployment;

public enum DesiredStatus {
    RUNNING, STOPPED
}
```

`ObservedStatus.java`:
```java
package net.siegeln.cameleer.saas.deployment;

public enum ObservedStatus {
    BUILDING, STARTING, RUNNING, FAILED, STOPPED
}
```

- [ ] **Step 2: Create DeploymentEntity**

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

import jakarta.persistence.*;
import org.hibernate.annotations.JdbcTypeCode;
import org.hibernate.type.SqlTypes;

import java.time.Instant;
import java.util.Map;

    public UUID getAppId() { return appId; }
    public void setAppId(UUID appId) { this.appId = appId; }
    public int getVersion() { return version; }
    public void setVersion(int version) { this.version = version; }
    public String getImageRef() { return imageRef; }
    public void setImageRef(String imageRef) { this.imageRef = imageRef; }
    public DesiredStatus getDesiredStatus() { return desiredStatus; }
    public void setDesiredStatus(DesiredStatus desiredStatus) { this.desiredStatus = desiredStatus; }
    public ObservedStatus getObservedStatus() { return observedStatus; }
    public void setObservedStatus(ObservedStatus observedStatus) { this.observedStatus = observedStatus; }
    public Map<String, Object> getOrchestratorMetadata() { return orchestratorMetadata; }
    public void setOrchestratorMetadata(Map<String, Object> orchestratorMetadata) { this.orchestratorMetadata = orchestratorMetadata; }
    public String getErrorMessage() { return errorMessage; }
    public void setErrorMessage(String errorMessage) { this.errorMessage = errorMessage; }
    public Instant getDeployedAt() { return deployedAt; }
    public void setDeployedAt(Instant deployedAt) { this.deployedAt = deployedAt; }
    public Instant getStoppedAt() { return stoppedAt; }
    public void setStoppedAt(Instant stoppedAt) { this.stoppedAt = stoppedAt; }
    public Instant getCreatedAt() { return createdAt; }
}
```

- [ ] **Step 3: Create DeploymentRepository**

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

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.stereotype.Repository;

import java.util.List;
import java.util.Optional;
import java.util.UUID;

@Repository
public interface DeploymentRepository extends JpaRepository<DeploymentEntity, UUID> {

    List<DeploymentEntity> findByAppIdOrderByVersionDesc(UUID appId);

    @Query("SELECT COALESCE(MAX(d.version), 0) FROM DeploymentEntity d WHERE d.appId = :appId")
    int findMaxVersionByAppId(UUID appId);

    Optional<DeploymentEntity> findByAppIdAndVersion(UUID appId, int version);
}
```

- [ ] **Step 4: Verify compilation**

Run: `mvn compile -B -q`
Expected: BUILD SUCCESS

- [ ] **Step 5: Commit**

```bash
git add src/main/java/net/siegeln/cameleer/saas/deployment/
git commit -m "feat: add deployment entity, repository, and status enums"
```

git commit -m "feat: add container log service with ClickHouse storage and log API"
```

## Task 16: Security Config + Docker Compose + CI Updates

**Files:**
- Modify: `src/main/java/net/siegeln/cameleer/saas/config/SecurityConfig.java`
- Modify: `docker-compose.yml`
- Modify: `.gitea/workflows/ci.yml`
- Create: `docker/runtime-base/Dockerfile`

- [ ] **Step 1: Update SecurityConfig to permit new API paths**

In the `apiFilterChain` method (the `@Order(2)` chain), update the `requestMatchers` for `permitAll` to include the new endpoints that should be accessible. The deployment status polling and log endpoints need auth (already covered by the default `.anyRequest().authenticated()`). No changes needed unless specific paths require different treatment.

Actually, all new endpoints require authentication (which is the default), so no security config changes are needed. Verify by checking the existing config — all `POST`/`GET`/`PATCH`/`DELETE` on `/api/**` already require auth.

- [ ] **Step 2: Update docker-compose.yml — add jardata volume and CAMELEER_AUTH_TOKEN**

Add `jardata` to the `volumes` section:

```yaml
volumes:
  pgdata:
  chdata:
  acme:
  jardata:
```

Add to the cameleer-saas service environment:
```yaml
      CAMELEER_AUTH_TOKEN: ${CAMELEER_AUTH_TOKEN:-default-bootstrap-token}
      CAMELEER_SERVER_ENDPOINT: http://cameleer-server:8081
      CLICKHOUSE_URL: jdbc:clickhouse://clickhouse:8123/cameleer
```

Add to the cameleer-saas service volumes:
```yaml
      - jardata:/data/jars
```

Add `CAMELEER_AUTH_TOKEN` to the cameleer-server service environment:
```yaml
      CAMELEER_AUTH_TOKEN: ${CAMELEER_AUTH_TOKEN:-default-bootstrap-token}
```

- [ ] **Step 3: Update .env.example with new variables**

Append:
```
CAMELEER_AUTH_TOKEN=change_me_bootstrap_token
CAMELEER_CONTAINER_MEMORY_LIMIT=512m
CAMELEER_CONTAINER_CPU_SHARES=512
```

- [ ] **Step 4: Create cameleer-runtime-base Dockerfile**

```dockerfile
FROM eclipse-temurin:21-jre-alpine
WORKDIR /app

# Agent JAR is copied during CI build from Gitea Maven registry
# ARG AGENT_JAR=cameleer-agent-1.0-SNAPSHOT-shaded.jar
COPY agent.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
```

- [ ] **Step 5: Update CI to exclude new integration tests**

In `.gitea/workflows/ci.yml`, update the Surefire excludes to add the new TestContainers-dependent tests:

```yaml
      - name: Build and Test (unit tests only)
        run: >-
          mvn clean verify -B
          -Dsurefire.excludes="**/AuthControllerTest.java,**/TenantControllerTest.java,**/LicenseControllerTest.java,**/AuditRepositoryTest.java,**/CameleerSaasApplicationTest.java,**/EnvironmentControllerTest.java,**/AppControllerTest.java,**/DeploymentControllerTest.java"
```

- [ ] **Step 6: Verify compilation**

Run: `mvn compile -B -q`
Expected: BUILD SUCCESS

- [ ] **Step 7: Run all unit tests**

Run: `mvn test -B -Dsurefire.excludes="**/AuthControllerTest.java,**/TenantControllerTest.java,**/LicenseControllerTest.java,**/AuditRepositoryTest.java,**/CameleerSaasApplicationTest.java,**/EnvironmentControllerTest.java,**/AppControllerTest.java,**/DeploymentControllerTest.java"`
Expected: All unit tests PASS

- [ ] **Step 8: Commit**

```bash
git add docker-compose.yml .env.example .gitea/workflows/ci.yml \
  docker/runtime-base/Dockerfile \
  src/main/java/net/siegeln/cameleer/saas/config/SecurityConfig.java
git commit -m "feat: update Docker Compose, CI, and add runtime-base Dockerfile"
```
