Self‑Hosting OpenClaw on UBOS
To self‑host OpenClaw on UBOS, install the UBOS platform, pull the OpenClaw source, configure the environment, and deploy using UBOS’s one‑click workflow, then secure and tune the service for production.
1. Introduction
OpenClaw is a powerful, open‑source web‑crawler and data‑extraction engine that many SaaS founders use to build market‑intelligence tools. When paired with UBOS, you get a fully managed, container‑native platform that abstracts away server maintenance, scaling, and CI/CD pipelines. This UBOS hosting guide is a step‑by‑step tutorial designed for developers and startup founders who want to self‑host OpenClaw quickly, securely, and cost‑effectively.
By the end of this guide you will have a production‑ready OpenClaw instance running on UBOS, with best‑practice security settings, performance tweaks, and a roadmap for future enhancements.
2. Prerequisites
System requirements
- Ubuntu 22.04 LTS (or any Debian‑based distro supported by UBOS)
- 4 CPU cores, 8 GB RAM (minimum for development); 8 CPU / 16 GB RAM recommended for production
- 50 GB SSD storage (OpenClaw’s index can grow quickly)
- Docker Engine 20.10+ and Docker Compose 2.x
- Outbound internet access for pulling images and dependencies
Required tools
- Git – version control
- VS Code or your preferred IDE
- cURL – API testing
- SSH client (OpenSSH) for remote server access
3. Installing UBOS
UBOS provides a single‑line installer that configures Docker, networking, and a secure runtime environment. Follow these steps:
- Log in to your server as a user with
sudoprivileges. - Run the official installer script:
curl -fsSL https://install.ubos.tech | sudo bash - After installation, verify the UBOS CLI:
ubos versionYou should see the current version and a confirmation that the daemon is running.
- Optionally, explore the UBOS platform overview to understand the dashboard and API endpoints.
4. Setting up OpenClaw
Downloading the source
OpenClaw’s source code is hosted on GitHub. Clone it into your UBOS workspace:
git clone https://github.com/openclaw/openclaw.git ~/openclawNavigate to the directory and checkout the latest stable tag:
cd ~/openclaw
git checkout $(git describe --tags `git rev-list --tags --max-count=1`)Configuring the environment
Create a .env file at the root of the project. UBOS reads this file automatically when building the container.
# .env
DB_HOST=postgres
DB_PORT=5432
DB_NAME=openclaw
DB_USER=claw_user
DB_PASSWORD=StrongP@ssw0rd!
REDIS_HOST=redis
REDIS_PORT=6379
# Optional: API key for external services
EXTERNAL_API_KEY=your_api_key_hereFor production, store secrets in UBOS’s encrypted vault instead of plain text. Use the CLI:
ubos secret set DB_PASSWORD --value "StrongP@ssw0rd!"5. Deploying OpenClaw on UBOS
UBOS leverages a declarative ubos.yml manifest. Below is a minimal example tailored for OpenClaw.
# ubos.yml
services:
openclaw:
image: openclaw/openclaw:latest
env_file: .env
ports:
- "8080:8080"
depends_on:
- postgres
- redis
restart: always
postgres:
image: postgres:15-alpine
environment:
POSTGRES_DB: openclaw
POSTGRES_USER: claw_user
POSTGRES_PASSWORD: ${DB_PASSWORD}
volumes:
- pgdata:/var/lib/postgresql/data
redis:
image: redis:7-alpine
volumes:
- redisdata:/data
volumes:
pgdata:
redisdata:Deploy with a single command:
ubos up -f ubos.ymlUBOS will pull the images, create the containers, and expose OpenClaw on http://your-server-ip:8080. Verify the deployment:
curl http://localhost:8080/healthYou should receive a JSON payload with "status":"ok".
6. Post‑deployment configuration
Security settings
- HTTPS termination: Use UBOS’s built‑in partner program to obtain a free Let’s Encrypt certificate. Add the following to
ubos.yml:tls: enabled: true domains: - yourdomain.com - Firewall rules: Restrict inbound traffic to ports 80/443 and the internal API port (8080) only from trusted IPs.
- Database hardening: Disable remote connections for PostgreSQL and enforce role‑based access control.
- Secret rotation: Schedule a cron job with UBOS to rotate
DB_PASSWORDevery 90 days.
Performance tuning
| Tuning Area | Recommended Setting | Why It Matters |
|---|---|---|
| CPU limits (Docker) | 2 cores per OpenClaw container | Prevents noisy neighbor effect on shared hosts |
| Memory reservation | 4 GB | Ensures stable crawling of large sites |
| Redis persistence | AOF + RDB snapshot every 5 min | Balances durability with speed |
| PostgreSQL connection pool | max_connections=200 | Accommodates concurrent crawlers |
After applying these settings, restart the services:
ubos restart openclaw postgres redis7. Common issues and troubleshooting
Even with a smooth deployment, you may encounter hiccups. Below is a quick‑reference table of typical problems and fixes.
| Symptom | Root Cause | Resolution |
|---|---|---|
| Health endpoint returns 500 | Missing DB credentials | Verify .env values and secret vault entries. |
| Crawls stall after 10 min | Redis memory limit reached | Increase maxmemory in Redis config or add a second node. |
| Docker container restarts repeatedly | Out‑of‑memory (OOM) kill | Allocate more RAM or lower concurrency in OpenClaw settings. |
| SSL certificate not applied | Domain DNS not pointing to server IP | Update DNS A record, then run ubos tls renew. |
If you encounter an obscure error, consult the OpenClaw GitHub issues page or open a new ticket with logs from ubos logs openclaw.
Conclusion and next steps
Self‑hosting OpenClaw on UBOS transforms a complex, multi‑service stack into a single, manageable deployment. By following this guide you have:
- Installed the UBOS platform on a clean Ubuntu server.
- Cloned and configured the OpenClaw source with secure environment variables.
- Deployed a production‑grade container stack using a declarative
ubos.ymlfile. - Applied security hardening, HTTPS, and performance tuning.
- Resolved common pitfalls and linked to further UBOS resources.
From here you can expand your setup:
- Integrate ChatGPT and Telegram integration to get AI‑driven crawl summaries directly in Slack or Teams.
- Leverage the Chroma DB integration for vector‑search over extracted content.
- Build a custom dashboard with the Web app editor on UBOS to visualize crawl metrics.
