HTTP Server Update - Production Components

Date: 2026-01-09 Version: 0.2.0 (from 0.1.0) Status: ✅ COMPLETE - ALL TESTS PASSING

Summary

Successfully updated the HTTP server (src/index.ts) to use production-grade components with enterprise reliability features. All endpoints tested and verified working.

Changes Made

1. Imports Updated ✅

Before:

import { createDokployClient } from './api/dokploy.js';

After:

import { createProductionDokployClient } from './api/dokploy-production.js';
import { ProductionDeployer } from './orchestrator/production-deployer.js';
import type { DeploymentState as OrchestratorDeploymentState } from './orchestrator/production-deployer.js';

2. Deployment State Enhanced ✅

Before (8 fields):

interface DeploymentState {
  id: string;
  name: string;
  status: 'initializing' | 'creating_project' | 'creating_application' | 'deploying' | 'completed' | 'failed';
  url?: string;
  error?: string;
  createdAt: Date;
  projectId?: string;
  applicationId?: string;
  progress: number;
  currentStep: string;
}

After (Extended with orchestrator state + logs):

interface HttpDeploymentState extends OrchestratorDeploymentState {
  logs: string[];
}

// OrchestratorDeploymentState includes:
// - phase: 9 detailed phases
// - status: 'in_progress' | 'success' | 'failure'
// - progress: 0-100
// - message: detailed step description
// - resources: { projectId, environmentId, applicationId, domainId }
// - timestamps: { started, completed }
// - error: { phase, message, code }

3. Deployment Logic Replaced ✅

Before (140 lines inline):

Direct API calls in deployStack() function
Basic try-catch error handling
4 manual deployment steps
No retry logic
No rollback mechanism

After (Production orchestrator):

async function deployStack(deploymentId: string): Promise<void> {
  const deployment = deployments.get(deploymentId);
  if (!deployment) {
    throw new Error('Deployment not found');
  }

  try {
    const client = createProductionDokployClient();
    const deployer = new ProductionDeployer(client);

    // Execute deployment with production orchestrator
    const result = await deployer.deploy({
      stackName: deployment.stackName,
      dockerImage: process.env.STACK_IMAGE || '...',
      domainSuffix: process.env.STACK_DOMAIN_SUFFIX || 'ai.flexinit.nl',
      port: 8080,
      healthCheckTimeout: 60000,
      healthCheckInterval: 5000,
    });

    // Update state with orchestrator result
    deployment.phase = result.state.phase;
    deployment.status = result.state.status;
    deployment.progress = result.state.progress;
    deployment.message = result.state.message;
    deployment.url = result.state.url;
    deployment.error = result.state.error;
    deployment.resources = result.state.resources;
    deployment.timestamps = result.state.timestamps;
    deployment.logs = result.logs;

    deployments.set(deploymentId, { ...deployment });
  } catch (error) {
    // Enhanced error handling
    deployment.status = 'failure';
    deployment.error = {
      phase: deployment.phase,
      message: error instanceof Error ? error.message : 'Unknown error',
      code: 'DEPLOYMENT_FAILED',
    };
    deployments.set(deploymentId, { ...deployment });
    throw error;
  }
}

4. Health Endpoint Enhanced ✅

Added Features Indicator:

{
  "status": "healthy",
  "version": "0.2.0",
  "features": {
    "productionClient": true,
    "retryLogic": true,
    "circuitBreaker": true,
    "autoRollback": true,
    "healthVerification": true
  }
}

5. New Endpoint Added ✅

GET /api/deployment/:deploymentId - Detailed deployment info for debugging:

{
  "success": true,
  "deployment": {
    "id": "dep_xxx",
    "stackName": "username",
    "phase": "completed",
    "status": "success",
    "progress": 100,
    "message": "Deployment complete",
    "url": "https://username.ai.flexinit.nl",
    "resources": {
      "projectId": "...",
      "environmentId": "...",
      "applicationId": "...",
      "domainId": "..."
    },
    "timestamps": {
      "started": "...",
      "completed": "..."
    },
    "logs": ["..."] // Last 50 log entries
  }
}

6. SSE Streaming Updated ✅

Enhanced progress events with more detail:

{
  "phase": "creating_application",
  "status": "in_progress",
  "progress": 50,
  "message": "Creating application container",
  "resources": {
    "projectId": "...",
    "environmentId": "..."
  }
}

Complete event includes duration:

{
  "url": "https://...",
  "status": "ready",
  "resources": {...},
  "duration": 32.45 // seconds
}

Production Features Now Active

1. Retry Logic ✅

Implementation: DokployProductionClient.request()
Strategy: Exponential backoff (1s → 2s → 4s → 8s → 16s)
Max Retries: 5
Smart Retry: Only retries 5xx and 429 errors

2. Circuit Breaker ✅

Implementation: CircuitBreaker class
Threshold: 5 consecutive failures
Timeout: 60 seconds
States: Closed → Open → Half-open
Purpose: Prevents cascading failures

3. Automatic Rollback ✅

Implementation: ProductionDeployer.rollback()
Trigger: Any phase failure
Actions: Deletes application, cleans up resources
Order: Reverse of creation (application → domain)

4. Health Verification ✅

Implementation: ProductionDeployer.verifyHealth()
Method: Polls /health endpoint
Timeout: 60 seconds (configurable)
Interval: 5 seconds
Purpose: Ensures application is running before completion

5. Structured Logging ✅

Implementation: DokployProductionClient.log()
Format: JSON with timestamp, level, phase, action, duration
Storage: In-memory per deployment
Access: Via /api/deployment/:id endpoint

6. Idempotency Checks ✅

Implementation: Multiple methods in orchestrator
Project: Checks if exists before creating
Application: Prevents duplicate creation
Domain: Checks existing domains

7. Resource Tracking ✅

Project ID: Captured during creation
Environment ID: Retrieved automatically
Application ID: Tracked through lifecycle
Domain ID: Stored for reference
