OpenClaw on Vultr (Docker + Firewall)

Introduction and quick answer

This guide shows how to run OpenClaw on Vultr using a VPS running Ubuntu 24.04 with Docker and a basic firewall. If you follow the steps below you will have a containerized OpenClaw instance, a minimal UFW firewall, and routines to update and secure the service. The guide assumes beginner familiarity with SSH and the command line.

Prerequisites

• A Vultr VPS running Ubuntu 24.04 (root or sudo user).
• SSH access to the server and a local terminal.
• Docker and Docker Compose (we install these below).
• Basic knowledge of editing files with a terminal editor (nano, vim).
• Check server requirements for OpenClaw resource guidance before launching.

Prepare the Vultr VPS

Use SSH to connect to your Vultr instance. Replace user and ip with your values.

ssh user@ip

Update packages and set the timezone if needed.

sudo apt update && sudo apt upgrade -y
sudo timedatectl set-timezone UTC

Install Docker, Docker Compose plugin, and Node.js

The commands below install Docker from the Ubuntu repositories (suitable for beginners) and a current Node.js LTS from NodeSource.

sudo apt install -y docker.io docker-compose-plugin
sudo systemctl enable --now docker
# Add your user to the docker group to run docker without sudo
sudo usermod -aG docker $USER
# Install Node.js LTS (NodeSource)
curl -fsSL https://deb.nodesource.com/setup_lts.x | sudo -E bash -
sudo apt install -y nodejs

Log out and log back in (or use newgrp docker) so group membership takes effect.

Deploy OpenClaw with Docker

Create a directory for OpenClaw and a minimal Docker Compose file. Below is an example compose snippet — adapt volumes, ports, and environment variables per your OpenClaw configuration.

mkdir -p ~/openclaw && cd ~/openclaw
cat > docker-compose.yml <<'EOF'
version: '3.8'
services:
  openclaw:
    image: openclaw/openclaw:latest
    restart: unless-stopped
    ports:
      - "3000:3000"
    environment:
      - NODE_ENV=production
    volumes:
      - ./data:/app/data
EOF

sudo docker compose up -d

Verify the container is running:

docker ps --filter name=openclaw

Firewall setup (UFW) — basic and safe

Use UFW to allow SSH and the application port (example uses 3000). Adjust ports for your OpenClaw settings.

sudo apt install -y ufw
sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw allow OpenSSH
sudo ufw allow 3000/tcp
sudo ufw enable
sudo ufw status verbose

For stricter control consider allowing SSH from your IP only and enabling rate limiting:

sudo ufw allow from x.x.x.x to any port 22 proto tcp
sudo ufw limit OpenSSH

Resource tiers and sizing guidance

When hosting OpenClaw on a VPS consider these resource tiers as baseline guidance:

• Small (development/testing): 1 vCPU, 1–2 GB RAM — suitable for experimenting or light workloads.
• Medium (small production): 2 vCPU, 4 GB RAM — recommended for light production with a few concurrent tasks.
• Large (steady production): 2–4 vCPU, 8+ GB RAM — for heavier automation workloads or multiple concurrent jobs.

Choose storage type (SSD recommended) and ensure networking bandwidth meets your workflow. See best hosting guidance for provider and plan considerations.

Update and maintenance

Keep the system, Docker images, and Node.js dependencies up to date. Example routine commands:

# Update system packages
sudo apt update && sudo apt upgrade -y
# Pull the latest OpenClaw image and recreate containers
cd ~/openclaw
sudo docker compose pull
sudo docker compose up -d
# Clean up unused images
docker image prune -f

Schedule regular updates using cron or an orchestration tool. Regular backups of ./data are recommended before updates.

Security recommendations

Key security steps for running OpenClaw on Vultr:

• Follow the VPS hardening steps in secure VPS documentation: disable root SSH login, use key-based auth, and install unattended-upgrades if appropriate.
• Use UFW (shown above) or a cloud firewall in Vultr's control panel to restrict access to required ports only.
• Run containers with least privilege: avoid mounting sensitive host paths and limit capabilities when possible.
• Keep secrets out of compose files; use environment managers or a secrets store for production.

Screenshots checklist (what to capture)

• Vultr instance list showing the Ubuntu 24.04 server.
• SSH session showing successful login and docker ps output.
• UFW status output demonstrating open ports.
• OpenClaw web UI (or API response) confirming the service is reachable.

Troubleshooting

• Container fails to start: run docker logs openclaw to inspect errors and check environment variables.
• Port not reachable: confirm UFW rules with sudo ufw status and ensure Vultr's control panel firewall allows the port.
• Permissions issues accessing volumes: ensure correct ownership on the host folder, for example sudo chown -R 1000:1000 ./data (adjust UID as required by the container).
• Node.js errors: check application logs and verify Node.js LTS is installed; reinstall if necessary.

When to scale or change tiers

If you observe increased CPU waits, memory pressure, or degraded response times under load, move up a resource tier. Monitor container metrics (CPU, memory, I/O) and choose the next tier to reduce contention. For distributed or high-availability needs consider multiple instances or managed services.

Closing recommendation

For a beginner-focused, provider-specific setup, use a small-to-medium Vultr instance to start and validate your OpenClaw workflows, then scale according to observed load. Follow the update and security sections regularly and keep configuration and data backed up. When you’re ready to begin provisioning, consider to Launch a Vultr VPS and use the steps above to deploy OpenClaw safely.
