# 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

* Oracle Cloud account ([signup](https://www.oracle.com/cloud/free/)) -- see [community signup guide](https://gist.github.com/rssnyder/51e3cfedd730e7dd5f4a816143b25dbd) if you hit issues
* Tailscale account (free at [tailscale.com](https://tailscale.com))
* An SSH key pair
* About 30 minutes

## Setup

<Steps>
  <Step title="Create an OCI instance">
    1. Log into [Oracle Cloud Console](https://cloud.oracle.com/).
    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>
  </Step>

  <Step title="Connect and update the system">
    ```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.
  </Step>

  <Step title="Configure user and hostname">
    ```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.
  </Step>

  <Step title="Install Tailscale">
    ```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`.
  </Step>

  <Step title="Install 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**.
  </Step>

  <Step title="Configure the gateway">
    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.service
    ```

    `gateway.trustedProxies=["127.0.0.1"]` here is only for the local Tailscale Serve proxy's forwarded-IP/local-client handling. It is **not** `gateway.auth.mode: "trusted-proxy"`. Diff viewer routes keep fail-closed behavior in this setup: raw `127.0.0.1` viewer requests without forwarded proxy headers can return `Diff not found`. Use `mode=file` / `mode=both` for attachments, or intentionally enable remote viewers and set `plugins.entries.diffs.config.viewerBaseUrl` (or pass a proxy `baseUrl`) if you need shareable viewer links.
  </Step>

  <Step title="Lock down VCN security">
    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.
  </Step>

  <Step title="Verify">
    ```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
    openclaw --version
    systemctl --user status openclaw-gateway.service
    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`).
  </Step>
</Steps>

## Verify the security posture

With the VCN locked down (only UDP 41641 open) and the Gateway bound to loopback, public traffic is blocked at the network edge and admin access is tailnet-only. That removes the need for several traditional VPS hardening steps:

| Traditional step   | Needed?     | Why                                                                       |
| ------------------ | ----------- | ------------------------------------------------------------------------- |
| UFW firewall       | No          | The VCN blocks traffic before it reaches the instance.                    |
| fail2ban           | No          | Port 22 is blocked at the VCN; no brute-force surface.                    |
| sshd hardening     | No          | Tailscale SSH does not use sshd.                                          |
| Disable root login | No          | Tailscale authenticates by tailnet identity, not system users.            |
| SSH key-only auth  | No          | Same — tailnet identity replaces system SSH keys.                         |
| IPv6 hardening     | Usually not | Depends on VCN/subnet settings; verify what is actually assigned/exposed. |

Still recommended:

* `chmod 700 ~/.openclaw` to restrict credential file permissions.
* `openclaw security audit` for an OpenClaw-specific posture check.
* Regular `sudo apt update && sudo apt upgrade` for OS patches.
* Review devices in the [Tailscale admin console](https://login.tailscale.com/admin) periodically.

Quick verification commands:

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
# Confirm no public ports are listening
sudo ss -tlnp | grep -v '127.0.0.1\|::1'

# Verify Tailscale SSH is active
tailscale status | grep -q 'offers: ssh' && echo "Tailscale SSH active"

# Optional: disable sshd entirely once Tailscale SSH is confirmed working
sudo systemctl disable --now ssh
```

## ARM notes

The Always Free tier is ARM (`aarch64`). Most OpenClaw features work fine; a small number of native binaries need ARM builds:

* Node.js, Telegram, WhatsApp (Baileys): pure JavaScript, no issues.
* Most npm packages with native code: pre-built `linux-arm64` artifacts available.
* Optional CLI helpers (e.g. Go/Rust binaries shipped by skills): check for an `aarch64` / `linux-arm64` release before installing.

Verify the architecture with `uname -m` (should print `aarch64`). For binaries without an ARM build, install from source or skip them.

## Persistence and backups

OpenClaw state lives under:

* `~/.openclaw/` — `openclaw.json`, per-agent `auth-profiles.json`, channel/provider state, and session data.
* `~/.openclaw/workspace/` — the agent workspace (SOUL.md, memory, artifacts).

These survive reboots. To take a portable snapshot:

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
openclaw backup create
```

## 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`.

## Troubleshooting

**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.service -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`.
