How to Deploy OpenClaw on GCP - Compute Engine Docker Guide

GCP Compute Engine is a good home for OpenClaw when you want cloud flexibility but still prefer a plain Linux VM you understand. The official docs present this as a Docker-based production VPS guide with durable host state, Docker Compose, and a local-first access model through SSH port forwarding.

What the official docs support

The documented flow covers gcloud project creation, enabling the Compute Engine API, creating a Debian 12 VM, installing Docker, cloning the OpenClaw repository, mounting host directories into the container, and publishing the gateway loopback-only so you reach it from your laptop through an SSH tunnel.

This path is best when you want Google Cloud primitives but not a highly abstract platform. You get predictable files, a normal VM lifecycle, and enough control to decide machine size, network exposure, and update rhythm yourself. The docs also give realistic cost and sizing notes instead of pretending the tiniest free-tier box is always enough.

What you need first

• A GCP account with billing enabled
• gcloud CLI or comfort with the Cloud Console
• A Compute Engine VM, usually Debian 12
• Docker, Docker Compose, and model credentials

Recommended setup flow

The design goal is host persistence plus a containerized runtime. That split keeps upgrades cleaner and makes recovery much easier.

1. Create the GCP project, enable billing, and turn on the Compute Engine API. The docs show both CLI and Cloud Console paths, but either way those API and billing steps have to happen before the VM exists.
2. Create the VM with a realistic machine type. The docs compare e2-medium, e2-small, and e2-micro, and they openly note that e2-micro often fails local Docker builds with exit 137 because 1 GB is usually too thin for this workflow.
3. SSH into the instance, install Docker, and verify docker plus docker compose are available. Then clone the OpenClaw repository so you can build the image locally and keep any required binaries inside it.
4. Create the persistent host directories under ~/.openclaw and ~/.openclaw/workspace, then add the .env file and docker-compose.yml using the documented volume mounts and loopback-only port mapping to 127.0.0.1:${OPENCLAW_GATEWAY_PORT}:18789.
5. Generate a keyring password, build and launch the stack, then reach the dashboard through gcloud compute ssh plus standard SSH port forwarding. The docs strongly prefer that tunnel-first model unless you are ready to manage firewalling and public exposure yourself.

gcloud compute instances create openclaw-gateway \
  --zone=us-central1-a \
  --machine-type=e2-small \
  --boot-disk-size=20GB \
  --image-family=debian-12 \
  --image-project=debian-cloud

Access, safety, and operational notes

The gateway can be exposed publicly, but the docs clearly favor SSH port forwarding as the default access model. That keeps the web UI private, keeps TLS decisions separate, and reduces how much internet-facing surface area you have to harden on day one.

The most practical insight in the GCP guide is the machine sizing honesty. e2-micro may be free-tier eligible, but the docs do not promise it is a good Docker build box. Starting at e2-small is usually the better operator move if you value your own time.

How to verify it is working

After launch, confirm the dashboard loads through the SSH tunnel, then restart the container once and verify that the bind-mounted config and workspace are still intact. That one restart proves whether you actually followed the persistence model or accidentally built a throwaway container.

Common gotchas

• e2-micro is often too small for reliable local Docker builds
• Persistent data belongs in host-mounted ~/.openclaw paths, not only inside the container
• The docs recommend SSH tunnel access instead of public port exposure by default

If you want the operator version with tighter rollout checklists, safer defaults, and more production patterns, The OpenClaw Playbook is the easiest shortcut.
