# 🚀 AI Dev Factory - Session Continuation Guide
|
||||
|
||||
**Last Updated:** 2024-11-28
|
||||
**Current Phase:** Phase 2 - OpenHands Integration (API Mode)
|
||||
**Time to Completion:** ~3-4 hours
|
||||
**Next Approach:** OpenHands Server API Mode ✅
|
||||
|
||||
---
|
||||
|
||||
## 📊 CURRENT STATUS
|
||||
|
||||
### ✅ What's Working:
|
||||
- **Gitea:** https://git.oky.sh (HTTPS, PostgreSQL backend)
|
||||
- **n8n:** https://n8n.oky.sh (HTTPS, workflow automation)
|
||||
- **Caddy:** Auto SSL with Let's Encrypt
|
||||
- **SSH:** n8n → localhost credentials configured
|
||||
- **OpenHands CLI:** `/home/bam/.local/bin/openhands` (v1.3.0)
|
||||
|
||||
### ⚠️ Current Blocker:
|
||||
- OpenHands headless mode (Docker) hangs on runtime startup
|
||||
- **Solution:** Switch to OpenHands Server API mode
|
||||
|
||||
### 🎯 Goal:
|
||||
Create automated workflow: Gitea push → n8n → OpenHands API → Build/Test
|
||||

|
||||
```
|
||||
|

|
||||
|
||||
## 🎯 NEXT STEPS: OpenHands Server API Setup
|
||||
|
||||
### Step 1: Start OpenHands in Server Mode (15 min)
|
||||
|
||||
**Goal:** Run OpenHands as persistent HTTP API service
|
||||
|
||||
**OpenHands serve uses port 3000 by default (cannot be changed in current version)**
|
||||
|
||||
```bash
|
||||
# Test server startup
|
||||
/home/bam/.local/bin/openhands serve
|
||||
|
||||
# Expected: Server starts, listens on http://localhost:3000
|
||||
```
|
||||
|
||||
**Create systemd service for persistence:**
|
||||
```bash
|
||||
sudo nano /etc/systemd/system/openhands.service
|
||||
|
||||
# Paste:
|
||||
[Unit]
|
||||
Description=OpenHands Server
|
||||
After=network.target docker.service
|
||||
Requires=docker.service
|
||||
|
||||
[Service]
|
||||
Type=simple
|
||||
User=bam
|
||||
WorkingDirectory=/home/bam
|
||||
Environment="PATH=/home/bam/.local/bin:/usr/local/bin:/usr/bin:/bin"
|
||||
EnvironmentFile=/home/bam/openhands/.env
|
||||
ExecStart=/home/bam/.local/bin/openhands serve
|
||||
Restart=always
|
||||
RestartSec=10
|
||||
|
||||
[Install]
|
||||
WantedBy=multi-user.target
|
||||
|
||||
# Save and enable:
|
||||
sudo systemctl daemon-reload
|
||||
sudo systemctl enable openhands.service
|
||||
sudo systemctl start openhands.service
|
||||
sudo systemctl status openhands.service
|
||||
```
|
||||
|
||||
**Verify:**
|
||||
```bash
|
||||
# Check if running
|
||||
curl http://localhost:3000/
|
||||
|
||||
# Check logs
|
||||
sudo journalctl -u openhands.service -f
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Step 1.5: Configure Backup LLM Models (10 min)
|
||||
|
||||
**Goal:** Setup DeepSeek V2 as fallback when MiniMax fails
|
||||
|
||||
OpenHands can use multiple LLM providers with automatic fallback.
|
||||
|
||||
**Check current config:**
|
||||
```bash
|
||||
cat /home/bam/.openhands/settings.json
|
||||
```
|
||||
|
||||
**Update settings to include backup models:**
|
||||
```bash
|
||||
nano /home/bam/.openhands/settings.json
|
||||
```
|
||||
|
||||
**Add LLM configuration:**
|
||||
```json
|
||||
{
|
||||
"LLM_MODEL": "openai/MiniMax-M2",
|
||||
"LLM_API_KEY": "${MINIMAX_API_KEY}",
|
||||
"LLM_BASE_URL": "https://api.minimax.io/v1",
|
||||
|
||||
"LLM_FALLBACK_MODELS": [
|
||||
{
|
||||
"model": "deepseek/deepseek-coder-v2",
|
||||
"api_key": "${DEEPSEEK_API_KEY}",
|
||||
"base_url": "https://api.deepseek.com/v1"
|
||||
},
|
||||
{
|
||||
"model": "gpt-4o",
|
||||
"api_key": "${OPENAI_API_KEY}",
|
||||
"base_url": "https://api.openai.com/v1"
|
||||
}
|
||||
],
|
||||
|
||||
"LLM_TIMEOUT": 60,
|
||||
"LLM_RETRY_COUNT": 3
|
||||
}
|
||||
```
|
||||
|
||||
**Verify API keys are loaded:**
|
||||
```bash
|
||||
cat /home/bam/openhands/.env
|
||||
# Should contain:
|
||||
# MINIMAX_API_KEY=xxx
|
||||
# DEEPSEEK_API_KEY=xxx
|
||||
# OPENAI_API_KEY=xxx (optional backup)
|
||||
```
|
||||
|
||||
**Note:** Exact config format may vary. Check OpenHands documentation or existing settings.json structure. The systemd service will load these env vars automatically.
|
||||
|
||||
**Restart OpenHands to apply:**
|
||||
```bash
|
||||
sudo systemctl restart openhands.service
|
||||
sudo systemctl status openhands.service
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Step 2: Discover API Endpoints (15 min)
|
||||
|
||||
**Goal:** Find available API endpoints for triggering tasks
|
||||
|
||||
**Check OpenHands documentation:**
|
||||
```bash
|
||||
# Look for API docs in help
|
||||
/home/bam/.local/bin/openhands serve --help
|
||||
|
||||
# Or check if web UI exposes API docs:
|
||||
# Visit: http://10.10.10.11:3000/docs
|
||||
# Or: http://10.10.10.11:3000/api/docs
|
||||
```
|
||||
|
||||
**Expected endpoints (typical OpenHands API):**
|
||||
```
|
||||
POST /api/sessions # Create new session
|
||||
POST /api/sessions/{id}/messages # Send task message
|
||||
GET /api/sessions/{id} # Get session status
|
||||
GET /api/sessions/{id}/events # Get execution events
|
||||
```
|
||||
|
||||
**Test manually:**
|
||||
```bash
|
||||
# Create session
|
||||
curl -X POST http://localhost:3000/api/sessions \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"workspace": "/home/bam/workspace",
|
||||
"model": "openai/MiniMax-M2",
|
||||
"api_key": "your_minimax_key"
|
||||
}'
|
||||
|
||||
# Response should include session_id
|
||||
```
|
||||
|
||||
**If API endpoints unclear:**
|
||||
- Check OpenHands GitHub docs
|
||||
- Inspect network requests in web UI (browser DevTools)
|
||||
- Look for OpenAPI/Swagger spec
|
||||
|
||||
---
|
||||
|
||||
### Step 3: Create n8n → OpenHands API Workflow (45 min)
|
||||
|
||||
**Goal:** Build n8n workflow that calls OpenHands API
|
||||
|
||||
#### Workflow Design:
|
||||
```
|
||||
[1] Manual Trigger (for testing)
|
||||
↓
|
||||
[2] HTTP Request - Create Session
|
||||
→ POST /api/sessions
|
||||
→ Save session_id
|
||||
↓
|
||||
[3] HTTP Request - Send Task
|
||||
→ POST /api/sessions/{session_id}/messages
|
||||
→ Body: { "task": "Create file test.txt" }
|
||||
↓
|
||||
[4] Wait 5 seconds
|
||||
↓
|
||||
[5] HTTP Request - Get Status (loop until done)
|
||||
→ GET /api/sessions/{session_id}
|
||||
→ Check if "status": "completed"
|
||||
↓
|
||||
[6] If Node - Check Success
|
||||
├─ TRUE → [7] Get Results
|
||||
└─ FALSE → [8] Error Handler
|
||||
```
|
||||
|
||||
#### n8n Configuration:
|
||||
|
||||
**Node 1: Manual Trigger**
|
||||
- Just add it, no config
|
||||
|
||||
**Node 2: HTTP Request - Create Session**
|
||||
```
|
||||
Method: POST
|
||||
URL: http://127.0.0.1:3000/api/sessions
|
||||
Headers:
|
||||
Content-Type: application/json
|
||||
Body:
|
||||
{
|
||||
"workspace": "/home/bam/workspace",
|
||||
"model": "openai/MiniMax-M2",
|
||||
"api_key": "{{$env.MINIMAX_API_KEY}}"
|
||||
}
|
||||
|
||||
Options:
|
||||
Response Format: JSON
|
||||
```
|
||||
|
||||
**Node 3: HTTP Request - Send Task**
|
||||
```
|
||||
Method: POST
|
||||
URL: http://127.0.0.1:3000/api/sessions/{{ $json.session_id }}/messages
|
||||
Body:
|
||||
{
|
||||
"task": "Create a file named test.txt with content: Hello from n8n API!"
|
||||
}
|
||||
```
|
||||
|
||||
**Node 4: Wait Node**
|
||||
```
|
||||
Time: 5 seconds
|
||||
```
|
||||
|
||||
**Node 5: HTTP Request - Get Status**
|
||||
```
|
||||
Method: GET
|
||||
URL: http://127.0.0.1:3000/api/sessions/{{ $node["HTTP Request"].json.session_id }}
|
||||
|
||||
# May need to loop this until status is "completed"
|
||||
# Use n8n Loop node if available
|
||||
```
|
||||
|
||||
**Node 6: SSH - Verify File Created**
|
||||
```
|
||||
Credentials: ai-dev-localhost
|
||||
Command: cat /home/bam/workspace/test.txt
|
||||
```
|
||||
|
||||
#### Test Workflow:
|
||||
1. Execute manually
|
||||
2. Check each node output
|
||||
3. Verify file created in /home/bam/workspace/
|
||||
|
||||
---
|
||||
|
||||
### Step 4: Gitea Webhook Integration (30 min)
|
||||
|
||||
**Goal:** Trigger n8n workflow on git push
|
||||
|
||||
#### In Gitea (https://git.oky.sh):
|
||||
1. Create test repository: `test-project`
|
||||
2. Go to Settings → Webhooks → Add Webhook → Gitea
|
||||
3. Configure:
|
||||
```
|
||||
Target URL: https://n8n.oky.sh/webhook/gitea-push
|
||||
HTTP Method: POST
|
||||
Content Type: application/json
|
||||
Secret: [generate random string]
|
||||
Trigger On: Push events
|
||||
Active: ✓
|
||||
```
|
||||
4. Test webhook
|
||||
|
||||
#### In n8n:
|
||||
1. Replace Manual Trigger with Webhook Trigger
|
||||
2. Configure:
|
||||
```
|
||||
Webhook URLs:
|
||||
Production: https://n8n.oky.sh/webhook/gitea-push
|
||||
|
||||
HTTP Method: POST
|
||||
|
||||
Authentication: Header Auth
|
||||
Name: X-Gitea-Signature
|
||||
Value: [your secret from Gitea]
|
||||
|
||||
Response:
|
||||
Mode: Last Node
|
||||
Code: 200
|
||||
```
|
||||
|
||||
3. Extract data:
|
||||
```
|
||||
Repository: {{ $json.repository.full_name }}
|
||||
Commit: {{ $json.commits[0].message }}
|
||||
Branch: {{ $json.ref }}
|
||||
```
|
||||
|
||||
4. Pass to OpenHands:
|
||||
```
|
||||
Task: "Build and test project {{ $json.repository.full_name }} on commit {{ $json.after }}"
|
||||
Workspace: "/home/bam/workspace/{{ $json.repository.name }}"
|
||||
```
|
||||
|
||||
#### Test:
|
||||
```bash
|
||||
# In test-project repo
|
||||
echo "Test" > README.md
|
||||
git add .
|
||||
git commit -m "Test webhook"
|
||||
git push origin main
|
||||
|
||||
# Check n8n workflow executes
|
||||
# Check OpenHands builds project
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Step 5: Build Workflow with Retry Logic (1-2 hours)
|
||||
|
||||
**Goal:** Production-ready workflow with error handling
|
||||
|
||||
#### Enhanced Workflow:
|
||||
```
|
||||
[1] Webhook Trigger (Gitea push)
|
||||
↓
|
||||
[2] Extract Repo Info
|
||||
↓
|
||||
[3] Clone/Update Repository (SSH)
|
||||
→ git clone or git pull
|
||||
↓
|
||||
[4] Create OpenHands Session
|
||||
↓
|
||||
[5] Send Build Task
|
||||
→ Task: "Run npm install, npm test, npm build"
|
||||
↓
|
||||
[6] Poll Status (Loop)
|
||||
→ Check every 10s
|
||||
→ Timeout: 5 minutes
|
||||
↓
|
||||
[7] If Node - Build Success?
|
||||
├─ YES → [8] Success Notification
|
||||
│ └─ Update commit status ✅
|
||||
│
|
||||
└─ NO → [9] Get Error Details
|
||||
↓
|
||||
[10] Send Feedback to OpenHands
|
||||
→ "Build failed with: {error}, please fix"
|
||||
↓
|
||||
[11] Retry Counter (max 3)
|
||||
├─ < 3 → Back to [5]
|
||||
└─ ≥ 3 → [12] Final Failure Notification
|
||||
```
|
||||
|
||||
#### Key Components:
|
||||
|
||||
**Clone Repository Node (SSH):**
|
||||
```bash
|
||||
cd /home/bam/workspace
|
||||
if [ -d "{{ $json.repo_name }}" ]; then
|
||||
cd {{ $json.repo_name }} && git pull
|
||||
else
|
||||
git clone {{ $json.clone_url }}
|
||||
fi
|
||||
```
|
||||
|
||||
**Build Task (to OpenHands):**
|
||||
```json
|
||||
{
|
||||
"task": "Navigate to /home/bam/workspace/{{ $json.repo_name }} and run: npm install && npm test && npm build. Report any errors.",
|
||||
"workspace": "/home/bam/workspace/{{ $json.repo_name }}",
|
||||
"max_iterations": 20
|
||||
}
|
||||
```
|
||||
|
||||
**Retry Logic (n8n Function Node):**
|
||||
```javascript
|
||||
// Get retry count from workflow static data
|
||||
const retries = $workflow.staticData.retry_count || 0;
|
||||
|
||||
if (retries >= 3) {
|
||||
return {
|
||||
action: 'fail',
|
||||
message: 'Max retries exceeded'
|
||||
};
|
||||
}
|
||||
|
||||
// Increment retry
|
||||
$workflow.staticData.retry_count = retries + 1;
|
||||
|
||||
return {
|
||||
action: 'retry',
|
||||
attempt: retries + 1,
|
||||
feedback: $json.error_message
|
||||
};
|
||||
```
|
||||
|
||||
**Success Notification (HTTP to Gitea API):**
|
||||
```
|
||||
POST https://git.oky.sh/api/v1/repos/{{ $json.repo }}/statuses/{{ $json.commit_sha }}
|
||||
Authorization: token YOUR_GITEA_TOKEN
|
||||
Body:
|
||||
{
|
||||
"state": "success",
|
||||
"description": "Build passed",
|
||||
"context": "openhands/build"
|
||||
}
|
||||
```
|
||||
|
||||

## 📋 TROUBLESHOOTING
|
||||
|
||||
### OpenHands Server Won't Start:
|
||||
|
||||
```bash
|
||||
# Check if port in use
|
||||
sudo netstat -tulpn | grep 3000
|
||||
|
||||
# Check OpenHands logs
|
||||
sudo journalctl -u openhands.service -n 50
|
||||
|
||||
# Try manual start to see errors
|
||||
/home/bam/.local/bin/openhands serve
|
||||
```
|
||||
|
||||
### API Endpoints Not Found:
|
||||
|
||||
```bash
|
||||
# Check OpenHands version
|
||||
/home/bam/.local/bin/openhands --version
|
||||
|
||||
# May need to update
|
||||
pipx upgrade openhands-ai
|
||||
|
||||
# Or reinstall
|
||||
pipx uninstall openhands-ai
|
||||
pipx install openhands-ai
|
||||
```
|
||||
|
||||
### n8n Cannot Reach OpenHands:
|
||||
|
||||
```bash
|
||||
# Test from n8n container
|
||||
docker exec -it n8n curl http://host.docker.internal:3000
|
||||
|
||||
# If fails, check if n8n has host.docker.internal access
|
||||
# May need to add to docker-compose:
|
||||
extra_hosts:
|
||||
- "host.docker.internal:host-gateway"
|
||||
```
|
||||
|
||||
### Webhook Not Triggering:
|
||||
|
||||
```bash

## 🚀 READY TO START?
|
||||
|
||||
**Pre-flight Checklist:**
|
||||
- [ ] All services running (docker compose ps)
|
||||
- [ ] Can access Gitea (https://git.oky.sh)
|
||||
- [ ] Can access n8n (https://n8n.oky.sh)
|
||||
- [ ] SSH to ai-dev-node working
|
||||
- [ ] Fresh terminal session
|
||||
|
||||
**First Command:**
|
||||
```bash
|
||||
/home/bam/.local/bin/openhands serve
|
||||
```
|
||||
|
||||
If starts successfully → proceed to Step 1 systemd service!
|
||||
If error → investigate OpenHands CLI installation
|
||||
|
||||

|
||||
|
||||
## 📝 NOTES
|
||||
|
||||
- **Port 3000:** OpenHands serve uses port 3000 (not configurable in CLI v1.3.0)
|
||||
- **Note:** This conflicts with Gitea's internal port 3000, but OK since Gitea exposed as 3333
|
||||
- OpenHands API: http://localhost:3000 (localhost only)
|
||||
- n8n will access via http://host.docker.internal:3000 from container
|
||||
- **API Mode vs Headless:** API is more reliable for automation
|
||||
- **Persistence:** systemd service ensures OpenHands survives reboots
|
||||
- **Security:** OpenHands API on localhost only (127.0.0.1)
|
||||
- **Scaling:** Can add more OpenHands instances later
|
||||
- **LLM Fallback:** MiniMax M2 → DeepSeek V2 → OpenAI GPT-4o (if configured)
|
||||
|
||||
**Good luck!** 🎯

|
||||
## ⚠️ Important Notes
|
||||
|
||||
### First Run Considerations
|
||||
|
||||
1. **Initial Conversation:** Takes 2-3 minutes (Docker image pull + runtime init)
|
||||
2. **Subsequent Runs:** 30-60 seconds
|
||||
3. **Runtime Containers:** Created per conversation, auto-removed when done
|
||||
4. **Resource Usage:** Each runtime uses ~500MB RAM, 1 vCPU
|
||||
|
||||
### Security Considerations
|
||||
|
||||
1. **OpenHands API:** Only accessible from localhost (127.0.0.1)
|
||||
2. **n8n Access:** Secured via HTTPS + Basic Auth
|
||||
3. **Gitea Access:** Secured via HTTPS
|
||||
4. **Docker Socket:** Mounted read-only in n8n
|
||||
|
||||
### Scaling Considerations
|
||||
|
||||
1. **Concurrent Builds:** Currently supports 1 build at a time
|
||||
2. **To Scale:** Run multiple OpenHands server instances on different ports
|
||||
3. **Load Balancing:** Add n8n load balancer node to distribute requests
|
||||
4. **Resource Limits:** Set Docker memory/CPU limits for runtime containers
|
||||

|
||||
|
||||
## 🐛 Troubleshooting Quick Reference
|
||||
|
||||
### Problem: OpenHands not responding
|
||||
|
||||
```bash
|
||||
# Check status
|
||||
sudo systemctl status openhands.service
|
||||
|
||||
# Check logs
|
||||
sudo journalctl -u openhands.service -n 50
|
||||
|
||||
# Restart service
|
||||
sudo systemctl restart openhands.service
|
||||
|
||||
# Test manually
|
||||
curl http://localhost:3000/api/options/agents
|
||||
```
|
||||
|
||||
### Problem: n8n can't reach OpenHands
|
||||
|
||||
```bash
|
||||
# Test connectivity from n8n
|
||||
docker exec n8n wget -O- http://172.18.0.1:3000/api/options/agents
|
||||
|
||||
# If fails, restart n8n
|
||||
cd /home/bam/services/services-stack
|
||||
docker compose restart n8n
|
||||
```
|
||||
|
||||
### Problem: Webhook not triggering
|
||||
|
||||
1. Check n8n workflow is **Active**
|
||||
2. Verify webhook URL matches
|
||||
3. Check Gitea "Recent Deliveries" for errors
|
||||
4. Test manual webhook trigger in Gitea
|
||||
|
||||
### Problem: Build timeout
|
||||
|
||||
1. Check OpenHands logs for errors
|
||||
2. Verify runtime container is running
|
||||
3. Increase retry limit in n8n workflow
|
||||
4. Check LLM API keys are valid

# Gitea → n8n → OpenHands Webhook Integration Guide
|
||||
|
||||
**Workflow:** Automatic CI/CD on every git push
|
||||
**File:** `/tmp/openhands-gitea-webhook-workflow.json`

|
||||
## 📋 Overview
|
||||
|
||||
This workflow automatically triggers OpenHands builds when you push to Gitea:
|
||||
|
||||
```
|
||||
Git Push → Gitea Webhook → n8n → OpenHands API → Build & Test → Results

||||
|
||||
```bash
|
||||
# Clone the test repository
|
||||
git clone https://git.oky.sh/[your-username]/openhands-test.git
|
||||
cd openhands-test
|
||||
|
||||
# Check current status
|
||||
git status
|
||||
```
|
||||
|
||||
### Step 8: Create a Simple Node.js Project
|
||||
|
||||
```bash
|
||||
# Initialize package.json
|
||||
cat > package.json << 'EOF'
|
||||
{
|
||||
"name": "openhands-test",
|
||||
"version": "1.0.0",
|
||||
"description": "Test project for OpenHands CI/CD",
|
||||
"main": "index.js",
|
||||
"scripts": {
|
||||
"test": "node test.js",
|
||||
"build": "echo 'Build completed successfully'"
|
||||
},
|
||||
"author": "",
|
||||
"license": "MIT"
|
||||
}
|
||||
EOF
|
||||
|
||||
# Create main file
|
||||
cat > index.js << 'EOF'
|
||||
function add(a, b) {
|
||||
return a + b;
|
||||
}
|
||||
|
||||
function multiply(a, b) {
|
||||
return a * b;
|
||||
}
|
||||
|
||||
module.exports = { add, multiply };
|
||||
EOF
|
||||
|
||||
# Create test file
|
||||
cat > test.js << 'EOF'
|
||||
const { add, multiply } = require('./index.js');
|
||||
|
||||
console.log('Running tests...');
|
||||
|
||||
// Test add function
|
||||
if (add(2, 3) === 5) {
|
||||
console.log('✓ add(2, 3) = 5 PASSED');
|
||||
} else {
|
||||
console.log('✗ add test FAILED');
|
||||
process.exit(1);
|
||||
}
|
||||
|
||||
// Test multiply function
|
||||
if (multiply(4, 5) === 20) {
|
||||
console.log('✓ multiply(4, 5) = 20 PASSED');
|
||||
} else {
|
||||
console.log('✗ multiply test FAILED');
|
||||
process.exit(1);
|
||||
}
|
||||
|
||||
console.log('\nAll tests passed! ✅');
|
||||
EOF
|
||||
|
||||
# Add all files
|
||||
git add .
|
||||
git commit -m "Add Node.js project with tests"
|
||||
git push origin main
|
||||
```
|
||||
|
||||
### Step 9: Monitor the Workflow
|
||||
|
||||
**In n8n:**
|
||||
1. Go to **"Executions"** (left sidebar)
|
||||
2. You should see a new execution appear
|
||||
3. Click on it to see the progress
|
||||
4. Watch as each node executes:
|
||||
- ✅ Webhook received
|
||||
- ✅ Repo info extracted
|
||||
- ✅ OpenHands session created
|
||||
- ✅ Build status polled
|
||||
- ✅ Events retrieved
|
||||
- ✅ Results analyzed
|
||||
|
||||
**Expected execution time:** 2-3 minutes (first time), 30-60 seconds (subsequent)
|
||||
|
||||
**In Gitea:**
|
||||
1. Go to your repository → **Settings** → **Webhooks**
|
||||
2. Click on your webhook
|
||||
3. Scroll to **"Recent Deliveries"**
|
||||
4. You should see the delivery with HTTP 200 response
|
||||
|
||||
### Step 10: Verify Build Results
|
||||
|
||||
**Check n8n Execution:**
|
||||
1. In n8n, click on the execution
|
||||
2. Click on **"Analyze Build Results"** node
|
||||
3. Check the output - you should see:
|
||||
```json
|
||||
{
|
||||
"repo": "username/openhands-test",
|
||||
"branch": "main",
|
||||
"commit": "abc123...",
|
||||
"build_status": "SUCCESS" or "FAILED",
|
||||
"total_events": 10+,
|
||||
"has_errors": false,
|
||||
"has_success": true
|
||||
}
|
||||
```
|
||||
|
||||
**Check OpenHands Logs:**
|
||||
```bash
|
||||
# List conversations
|
||||
curl http://localhost:3000/api/conversations | python3 -m json.tool
|
||||
|
||||
# Get specific conversation events (use conversation_id from n8n)
|
||||
curl "http://localhost:3000/api/conversations/[conversation-id]/events" | python3 -m json.tool
|
||||
```
|
||||
|
||||
**Check Runtime Container:**
|
||||
```bash
|
||||
# Find the runtime container
|
||||
docker ps | grep openhands-runtime
|
||||
|
||||
# Check if tests ran successfully
|
||||
docker exec [container-name] cat /workspace/test.js
|
||||
|
||||
# Check installed packages
|
||||
docker exec [container-name] ls -la /workspace/node_modules
|
||||
```
|
||||

|
||||
## 🎯 Workflow Logic Explained
|
||||
|
||||
### Node 1: Gitea Webhook
|
||||
- **Trigger:** Receives POST requests from Gitea
|
||||
- **Path:** `/webhook/gitea-push`
|
||||
- **Payload:** Complete webhook payload with repo, commit, pusher info
|
||||
|
||||
### Node 2: Extract Repo Info
|
||||
- Parses Gitea webhook payload
|
||||
- Extracts: repository name, clone URL, branch, commit SHA, message
|
||||
- Builds task description for OpenHands
|
||||
|
||||
### Node 3: Create OpenHands Session
|
||||
- **POST** `/api/conversations`
|
||||
- Passes repository URL and branch
|
||||
- Includes custom build task
|
||||
|
||||
### Node 4-8: Status Polling Loop
|
||||
- Waits 10s initially
|
||||
- Checks status every 15s
|
||||
- Max 20 retries (5 minutes timeout)
|
||||
- Loops until status is RUNNING, STOPPED, or AWAITING_USER_INPUT
|
||||
|
||||
### Node 9: Get Build Events
|
||||
- Retrieves all events from the conversation
|
||||
- Contains logs, actions, observations
|
||||
|
||||
### Node 10: Analyze Build Results
|
||||
- Scans events for error/success indicators
|
||||
- Determines final build status
|
||||
- Counts total events
|
||||
|
||||
### Node 11-12: Format & Respond
|
||||
- Formats response JSON
|
||||
- Sends back to Gitea webhook
|
||||
|
||||
---
|
||||
|
||||
## 📊 Customizing the Workflow
|
||||
|
||||
### Change Build Commands
|
||||
|
||||
Edit the **"Extract Repo Info"** node, modify the `task` variable:
|
||||
|
||||
```javascript
|
||||
const task = `Build and test project ${repoFullName}. ` +
|
||||
`Run: npm install && npm run lint && npm test && npm build`;
|
||||
```
|
||||
|
||||
### Add Python Support
|
||||
|
||||
```javascript
|
||||
const task = `Clone repository, install dependencies with pip, ` +
|
||||
`and run: pip install -r requirements.txt && pytest`;
|
||||
```
|
||||
|
||||
### Add Docker Build
|
||||
|
||||
```javascript
|
||||
const task = `Build Docker image: docker build -t ${repoName}:${commitSha.substring(0,8)} . ` +
|
||||
`Run tests in container: docker run ${repoName} npm test`;
|
||||
```
|
||||
|
||||
### Filter by Branch
|
||||
|
||||
Add a filter after webhook trigger:
|
||||
|
||||
```javascript
|
||||
// In Extract Repo Info node, add at the top:
|
||||
const branch = payload.ref?.replace('refs/heads/', '') || '';
|
||||
|
||||
if (branch !== 'main' && branch !== 'develop') {
|
||||
throw new Error('Skipping build for branch: ' + branch);
|
||||
}
|
||||
```
|
||||
|
||||
### Add Notifications
|
||||
|
||||
After "Analyze Build Results", add:
|
||||
- **Slack notification node**
|
||||
- **Email node**
|
||||
- **Discord webhook**
|
||||
|
||||
Example for Slack:
|
||||
```json
|
||||
{
|
||||
"channel": "#ci-cd",
|
||||
"text": "Build {{$json.build_status}} for {{$json.repo}} on {{$json.branch}}"
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 🐛 Troubleshooting
|
||||
|
||||
### Webhook Not Triggering
|
||||
|
||||
**Problem:** No execution appears in n8n after git push
|
||||
|
||||
**Solutions:**
|
||||
1. Check workflow is **Active** (toggle at top of workflow)
|
||||
2. Verify webhook URL in Gitea matches n8n webhook path
|
||||
3. Check Gitea "Recent Deliveries" for errors
|
||||
4. Test webhook manually in Gitea UI
|
||||
|
||||
**Debug:**
|
||||
```bash
|
||||
# Check n8n logs
|
||||
docker logs n8n | grep webhook
|
||||
|
||||
# Test webhook manually
|
||||
curl -X POST https://n8n.oky.sh/webhook/gitea-push \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"test": "data"}'
|
||||
```
|
||||
|
||||
### Build Timeout
|
||||
|
||||
**Problem:** Workflow hits max retries (5 minutes)
|
||||
|
||||
**Solutions:**
|
||||
1. Increase max retries in "Retry Counter" node (change `maxRetries` from 20 to 40)
|
||||
2. Increase wait time from 15s to 30s
|
||||
3. Check OpenHands logs for errors:
|
||||
```bash
|
||||
sudo journalctl -u openhands.service -f
|
||||
```
|
||||
|
||||
### Build Always Shows "UNKNOWN"
|
||||
|
||||
**Problem:** Build status is never SUCCESS or FAILED
|
||||
|
||||
**Solutions:**
|
||||
1. Check event messages don't contain success/error keywords
|
||||
2. Modify "Analyze Build Results" node to look for different patterns:
|
||||
```javascript
|
||||
const hasSuccess = events.some(e =>
|
||||
e.message?.includes('Tests passed') ||
|
||||
e.message?.includes('Build complete')
|
||||
);
|
||||
```
|
||||
|
||||
### OpenHands Connection Failed
|
||||
|
||||
**Problem:** "Cannot reach 172.18.0.1:3000"
|
||||
|
||||
**Solutions:**
|
||||
1. Verify OpenHands is running:
|
||||
```bash
|
||||
sudo systemctl status openhands.service
|
||||
curl http://localhost:3000/api/options/agents
|
||||
```
|
||||
|
||||
2. Test from n8n container:
|
||||
```bash
|
||||
docker exec n8n wget -O- http://172.18.0.1:3000/api/options/agents
|
||||
```
|
||||
|
||||
3. Restart n8n:
|
||||
```bash
|
||||
cd /home/bam/services/services-stack
|
||||
docker compose restart n8n
|
||||
```
|
||||

|
||||
3. You should see events showing:
|
||||
- Agent state changes
|
||||
- File creation action
|
||||
- Success/completion messages
|
||||
|
||||
#### On the Server:
|
||||
```bash
|
||||
# Check if OpenHands created the file
|
||||
docker exec openhands-runtime-[conversation-id] cat /workspace/hello.txt
|
||||
|
||||
# Or check all runtime containers
|
||||
docker ps | grep openhands-runtime
|
||||
```
|
||||
|
||||
#### Via API:
|
||||
```bash
|
||||
# Get conversation ID from n8n output, then:
|
||||
curl http://localhost:3000/api/conversations/[conversation-id]/events
|
||||
```

|
||||
## 🔧 Workflow Configuration Details
|
||||
|
||||
### Node 1: Create Conversation
|
||||
- **Type:** HTTP Request
|
||||
- **URL:** `http://172.18.0.1:3000/api/conversations`
|
||||
- **Method:** POST
|
||||
- **Body:**
|
||||
```json
|
||||
{
|
||||
"initial_user_msg": "Create a file named hello.txt with content: Hello from n8n automated workflow!"
|
||||
}
|
||||
```
|
||||
|
||||
### Node 2: Wait 5s
|
||||
- Gives OpenHands time to start initializing
|
||||
|
||||
### Node 3: Get Conversation Status
|
||||
- **URL:** `http://172.18.0.1:3000/api/conversations/{{ $json.conversation_id }}`
|
||||
- **Method:** GET
|
||||
- Uses conversation_id from previous node
|
||||
|
||||
### Node 4: Check If Ready
|
||||
- **Logic:** Status is RUNNING, AWAITING_USER_INPUT, or STOPPED
|
||||
- **True:** Proceed to get events
|
||||
- **False:** Wait 10 more seconds and check again
|
||||
|
||||
### Node 5: Get Events
|
||||
- **URL:** `http://172.18.0.1:3000/api/conversations/{id}/events?limit=20`
|
||||
- Retrieves last 20 events to see what happened
|
||||
|
||||

||||
|
||||
## 🎨 Customizing the Workflow
|
||||
|
||||
### Change the Task:
|
||||
1. Click on **"Create Conversation"** node
|
||||
2. Under **"Body Parameters"**
|
||||
3. Change `initial_user_msg` to your desired task:
|
||||
```
|
||||
"Run npm install && npm test && npm build"
|
||||
"Clone https://github.com/user/repo and run tests"
|
||||
"Create a Python script that does X"
|
||||
```
|
||||
|
||||
### Add Repository Support:
|
||||
Add these parameters to the Create Conversation node:
|
||||
```json
|
||||
{
|
||||
"initial_user_msg": "Run tests",
|
||||
"repository": "https://github.com/user/repo",
|
||||
"selected_branch": "main"
|
||||
}
|
||||
```
|
||||
|
||||
### Increase Timeout:
|
||||
1. Modify **"Wait 10s More"** node
|
||||
2. Change amount to 15 or 20 seconds
|
||||
3. For long-running tasks, add a maximum retry counter
|
||||
|
||||

|
||||
|
||||
## 🐛 Troubleshooting
|
||||
|
||||
### Error: "Connection refused" or "Cannot reach 172.18.0.1:3000"
|
||||
|
||||
**Check OpenHands is running:**
|
||||
```bash
|
||||
sudo systemctl status openhands.service
|
||||
curl http://localhost:3000/api/options/agents
|
||||
```
|
||||
|
||||
**Restart OpenHands if needed:**
|
||||
```bash
|
||||
sudo systemctl restart openhands.service
|
||||
```
|
||||
|
||||
### Error: Workflow stuck in "STARTING" status
|
||||
|
||||
**This is normal for first run!**
|
||||
- Runtime container is being created
|
||||
- Wait 2-3 minutes
|
||||
- Check runtime logs:
|
||||
```bash
|
||||
docker logs [openhands-runtime-container-name]
|
||||
```
|
||||
|
||||
### Error: Workflow loops forever
|
||||
|
||||
**Add a loop counter:**
|
||||
1. Add a **"Function"** node before "Wait 10s More"
|
||||
2. Add this code:
|
||||
```javascript
|
||||
// Check static data
|
||||
const retries = $workflow.staticData.retries || 0;
|
||||
|
||||
if (retries > 20) {
|
||||
throw new Error('Max retries exceeded (5 minutes)');
|
||||
}
|
||||
|
||||
$workflow.staticData.retries = retries + 1;
|
||||
return $input.all();
|
||||
```
|
||||
|
||||
### No events returned
|
||||
|
||||
**Conversation may still be initializing**
|
||||
- Wait longer before checking events
|
||||
- Check conversation status shows "RUNNING" or "STOPPED"
|
||||
|
||||

|
||||
|
||||
## 🚀 Next Steps
|
||||
|
||||
### Test Successful? Move to Gitea Webhook Integration!
|
||||
|
||||
Once this workflow works, you can:
|
||||
|
||||
1. **Replace Manual Trigger with Webhook Trigger**
|
||||
- Node type: "Webhook"
|
||||
- URL: `https://n8n.oky.sh/webhook/gitea-push`
|
||||
|
||||
2. **Add Gitea Webhook**
|
||||
- Repository → Settings → Webhooks
|
||||
- Target URL: The webhook URL from n8n
|
||||
- Trigger: Push events
|
||||
|
||||
3. **Extract Repository Info**
|
||||
- Add "Set" node after webhook
|
||||
- Extract: `{{ $json.repository.full_name }}`
|
||||
- Extract: `{{ $json.commits[0].message }}`
|
||||
|
||||
4. **Pass to OpenHands**
|
||||
```json
|
||||
{
|
||||
"initial_user_msg": "Clone {{ $json.repository.clone_url }}, run tests",
|
||||
"repository": "{{ $json.repository.clone_url }}",
|
||||
"selected_branch": "{{ $json.ref }}"
|
||||
}

|
||||
→ Get conversation_id
|
||||
|
||||
2. Wait for runtime initialization
|
||||
|
||||
3. POST /api/conversations/{id}/message
|
||||
→ "Run npm install && npm test && npm build"
|
||||
|
||||
4. Poll events for results
|
||||
|
||||
5. On failure, POST /api/conversations/{id}/message

|
||||
|
||||
## 🧪 Testing with curl
|
||||
|
||||
### Test 1: Create Conversation
|
||||
```bash
|
||||
curl -X POST http://localhost:3000/api/conversations \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"initial_user_msg": "Create a file named test.txt with content: Hello World"}'
|
||||
```
|
||||
|
||||
### Test 2: Check Status
|
||||
```bash
|
||||
CONV_ID="your-conversation-id-here"
|
||||
curl http://localhost:3000/api/conversations/${CONV_ID}
|
||||
```
|
||||
|
||||
### Test 3: Get Events
|
||||
```bash
|
||||
curl "http://localhost:3000/api/conversations/${CONV_ID}/events?limit=10"
|
||||
```
|
||||
|
||||
### Test 4: Send Additional Message
|
||||
```bash
|
||||
curl -X POST http://localhost:3000/api/conversations/${CONV_ID}/message \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"content": "Now create another file called test2.txt"}'
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 📊 Response Status Codes
|
||||
|
||||
- `200 OK` - Successful request
|
||||
- `422 Unprocessable Entity` - Invalid request body
|
||||
- `404 Not Found` - Conversation not found
|
||||
- `500 Internal Server Error` - Server error
|
||||
|
||||
---
|
||||
|
||||
## 🐛 Common Issues
|
||||
|
||||
### Issue: Conversation stuck in "STARTING"
|
||||
- **Cause:** Runtime container still initializing
|
||||
- **Solution:** Wait 2-3 minutes on first run, ~30s on subsequent runs
|
||||
- **Check:** `docker logs openhands-runtime-{conversation_id}`
|
||||
|
||||
### Issue: "Field required" error
|
||||
- **Cause:** Missing required fields in request body
|
||||
- **Solution:** Check OpenAPI spec at /docs for exact schema
|
||||
|
||||
### Issue: Events not updating
|
||||
- **Cause:** Agent may be waiting for runtime or processing
|
||||
- **Solution:** Poll events endpoint every 5-10 seconds
