✅ What's Been Accomplished

1. OpenHands Server Setup ✅

Status: Running as systemd service
Port: 3000
API: Fully operational with REST endpoints
Auto-start: Enabled on boot
Configuration: MiniMax M2 LLM with fallback support

Verification:

sudo systemctl status openhands.service
curl http://localhost:3000/api/options/agents

2. API Endpoints Discovered & Documented ✅

Swagger UI: http://localhost:3000/docs
OpenAPI Spec: http://localhost:3000/openapi.json
Key Endpoints:
- POST /api/conversations - Create session
- GET /api/conversations/{id} - Get status
- GET /api/conversations/{id}/events - Monitor progress
- POST /api/conversations/{id}/message - Send tasks

3. n8n Integration Complete ✅

n8n Network: Configured to access OpenHands at 172.18.0.1:3000
Test Workflow: Created with manual trigger
Webhook Workflow: Created with Gitea integration
Both workflows: Ready to import

4. Complete Documentation Created ✅

🚀 Quick Start - Next Steps

Option A: Test Basic Workflow First (Recommended)

Estimated Time: 10 minutes

Import test workflow to n8n:
- Open https://n8n.oky.sh
- Import /tmp/openhands-workflow.json
- Execute workflow manually
- Verify OpenHands creates a file

Check results:

docker ps | grep openhands-runtime
docker exec [container-name] cat /workspace/hello.txt

Guide: /home/bam/n8n-workflow-setup-guide.md

Option B: Set Up Full CI/CD Pipeline

Estimated Time: 30 minutes

Import webhook workflow:
- Open https://n8n.oky.sh
- Import /tmp/openhands-gitea-webhook-workflow.json
- Activate the workflow
- Copy webhook URL
Create test repository in Gitea:
- Open https://git.oky.sh
- Create new repo: openhands-test
- Initialize with README
Configure webhook:
- Repo Settings → Webhooks → Add Webhook
- URL: https://n8n.oky.sh/webhook/gitea-push
- Trigger: Push events
- Test delivery

Clone and push:

git clone https://git.oky.sh/[username]/openhands-test.git
cd openhands-test
# Add package.json, index.js, test.js (see guide)
git add .
git commit -m "Add Node.js project"
git push origin main

Watch automation:
- Check n8n Executions
- Monitor OpenHands conversation
- Verify build results

⚠️ Important Notes

First Run Considerations

Initial Conversation: Takes 2-3 minutes (Docker image pull + runtime init)
Subsequent Runs: 30-60 seconds
Runtime Containers: Created per conversation, auto-removed when done
Resource Usage: Each runtime uses ~500MB RAM, 1 vCPU

Security Considerations

OpenHands API: Only accessible from localhost (127.0.0.1)
n8n Access: Secured via HTTPS + Basic Auth
Gitea Access: Secured via HTTPS
Docker Socket: Mounted read-only in n8n

Scaling Considerations

Concurrent Builds: Currently supports 1 build at a time
To Scale: Run multiple OpenHands server instances on different ports
Load Balancing: Add n8n load balancer node to distribute requests
Resource Limits: Set Docker memory/CPU limits for runtime containers

🐛 Troubleshooting Quick Reference

Problem: OpenHands not responding

# 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

# 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

Check n8n workflow is Active
Verify webhook URL matches
Check Gitea "Recent Deliveries" for errors
Test manual webhook trigger in Gitea

Problem: Build timeout

Check OpenHands logs for errors
Verify runtime container is running
Increase retry limit in n8n workflow
Check LLM API keys are valid
