Oracle Cloud

Run a persistent OpenClaw Gateway on Oracle Cloud’s Always Free ARM tier (up to 4 OCPU, 24 GB RAM, 200 GB storage) at no cost.

Prerequisites

安装配置

1. Log into Oracle Cloud Console.
2. Navigate to Compute > Instances > Create Instance.
3. Configure:
* Name: openclaw
* Image: Ubuntu 24.04 (aarch64)
* Shape: VM.Standard.A1.Flex (Ampere ARM)
* OCPUs: 2 (or up to 4)
* Memory: 12 GB (or up to 24 GB)
* Boot volume: 50 GB (up to 200 GB free)
* SSH key: Add your public key
4. Click Create and note the public IP address.

<Tip>
  If instance creation fails with "Out of capacity", try a different availability domain or retry later. Free tier capacity is limited.
</Tip>

“`bash theme={“theme”:{“light”:”min-light”,”dark”:”min-dark”}}
ssh ubuntu@YOUR_PUBLIC_IP

sudo apt update && sudo apt upgrade -y
sudo apt install -y build-essential
```

`build-essential` is required for ARM compilation of some dependencies.

bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
sudo hostnamectl set-hostname openclaw
sudo passwd ubuntu
sudo loginctl enable-linger ubuntu

Enabling linger keeps user services running after logout.

bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
curl -fsSL https://tailscale.com/install.sh | sh
sudo tailscale up --ssh --hostname=openclaw

From now on, connect via Tailscale: `ssh ubuntu@openclaw`.

bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
curl -fsSL https://openclaw.ai/install.sh | bash
source ~/.bashrc

When prompted "How do you want to hatch your bot?", select **Do this later**.

Use token auth with Tailscale Serve for secure remote access.

```bash  theme={"theme":{"light":"min-light","dark":"min-dark"}}
openclaw config set gateway.bind loopback
openclaw config set gateway.auth.mode token
openclaw doctor --generate-gateway-token
openclaw config set gateway.tailscale.mode serve
openclaw config set gateway.trustedProxies '["127.0.0.1"]'

systemctl --user restart openclaw-gateway
```

Block all traffic except Tailscale at the network edge:

1. Go to **Networking > Virtual Cloud Networks** in the OCI Console.
2. Click your VCN, then **Security Lists > Default Security List**.
3. **Remove** all ingress rules except `0.0.0.0/0 UDP 41641` (Tailscale).
4. Keep default egress rules (allow all outbound).

This blocks SSH on port 22, HTTP, HTTPS, and everything else at the network edge. You can only connect via Tailscale from this point on.

bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
openclaw --version
systemctl --user status openclaw-gateway
tailscale serve status
curl http://localhost:18789

Access the Control UI from any device on your tailnet:

```
https://openclaw.<tailnet-name>.ts.net/
```

Replace `<tailnet-name>` with your tailnet name (visible in `tailscale status`).

Fallback: SSH tunnel

If Tailscale Serve is not working, use an SSH tunnel from your local machine:

bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
ssh -L 18789:127.0.0.1:18789 ubuntu@openclaw

Then open http://localhost:18789.

故障排查

Instance creation fails (“Out of capacity”) — Free tier ARM instances are popular. Try a different availability domain or retry during off-peak hours.

Tailscale will not connect — Run sudo tailscale up --ssh --hostname=openclaw --reset to re-authenticate.

Gateway will not start — Run openclaw doctor --non-interactive and check logs with journalctl --user -u openclaw-gateway -n 50.

ARM binary issues — Most npm packages work on ARM64. For native binaries, look for linux-arm64 or aarch64 releases. Verify architecture with uname -m.
