# 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**:
|
||||
```typescript
|
||||
import { createDokployClient } from './api/dokploy.js';
|
||||
```
|
||||
|
||||
**After**:
|
||||
```typescript
|
||||
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):
|
||||
```typescript
|
||||
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):
|
||||
```typescript
|
||||
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):
|
||||
```typescript
|
||||
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**:
|
||||
```json
|
||||
{
|
||||
"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:
|
||||
```json
|
||||
{
|
||||
"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:
|
||||
```javascript
|
||||
{
|
||||
"phase": "creating_application",
|
||||
"status": "in_progress",
|
||||
"progress": 50,
|
||||
"message": "Creating application container",
|
||||
"resources": {
|
||||
"projectId": "...",
|
||||
"environmentId": "..."
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Complete event** includes duration:
|
||||
```javascript
|
||||
{
|
||||
"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
|
||||

1. ✅ **Deploy to Production** - Ready for `portal.ai.flexinit.nl`
|
||||
2. ✅ **Monitor Deployments** - Use `/api/deployment/:id` for debugging
|
||||
3. ✅ **Analyze Logs** - Check structured logs for performance metrics
|
||||
4. ✅ **Circuit Breaker Monitoring** - Watch for threshold breaches
|
||||
|
||||

|
||||
|
||||
## Performance Impact
|
||||
|
||||
**Before**:
|
||||
- Single API call failure = deployment failure
|
||||
- No retry = transient errors cause failures
|
||||
- No rollback = orphaned resources
|
||||
|
||||
**After**:
|
||||
- 5 retries with exponential backoff
|
||||
- Circuit breaker prevents cascade
|
||||
- Automatic rollback on failure
|
||||
- Health verification ensures success
|
||||
- **Result**: Higher success rate, cleaner failures
|
||||

||||
## Migration Notes
|
||||
|
||||
### For Developers
|
||||
- Old server backed up to `src/index-legacy.ts.backup`
|
||||
- Can revert with: `cp src/index-legacy.ts.backup src/index.ts`
|
||||
- Production server is drop-in replacement
|
||||
|
||||
### For Operations
|
||||
- Monitor circuit breaker state via health endpoint
|
||||
- Check `/api/deployment/:id` for debugging
|
||||
- Logs available in deployment state
|
||||
- Health check timeout is expected (SSL provisioning)
|
||||
