Docker VM Runtime

Shared runtime steps for VM-based Docker installs such as GCP, Hetzner, and similar VPS providers.

​
Bake required binaries into the image

Installing binaries inside a running container is a trap. Anything installed at runtime will be lost on restart. All external binaries required by skills must be installed at image build time. The examples below show three common binaries only:
  • gog for Gmail access
  • goplaces for Google Places
  • wacli for WhatsApp
These are examples, not a complete list. You may install as many binaries as needed using the same pattern. If you add new skills later that depend on additional binaries, you must:
  1. Update the Dockerfile
  2. Rebuild the image
  3. Restart the containers
Example Dockerfile 
FROM node:24-bookworm

RUN apt-get update && apt-get install -y socat && rm -rf /var/lib/apt/lists/*

# Example binary 1: Gmail CLI
RUN curl -L https://github.com/steipete/gog/releases/latest/download/gog_Linux_x86_64.tar.gz \
  | tar -xz -C /usr/local/bin && chmod +x /usr/local/bin/gog

# Example binary 2: Google Places CLI
RUN curl -L https://github.com/steipete/goplaces/releases/latest/download/goplaces_Linux_x86_64.tar.gz \
  | tar -xz -C /usr/local/bin && chmod +x /usr/local/bin/goplaces

# Example binary 3: WhatsApp CLI
RUN curl -L https://github.com/steipete/wacli/releases/latest/download/wacli_Linux_x86_64.tar.gz \
  | tar -xz -C /usr/local/bin && chmod +x /usr/local/bin/wacli

# Add more binaries below using the same pattern

WORKDIR /app
COPY package.json pnpm-lock.yaml pnpm-workspace.yaml .npmrc ./
COPY ui/package.json ./ui/package.json
COPY scripts ./scripts

RUN corepack enable
RUN pnpm install --frozen-lockfile

COPY . .
RUN pnpm build
RUN pnpm ui:install
RUN pnpm ui:build

ENV NODE_ENV=production

CMD ["node","dist/index.js"]

​
Build and launch

docker compose build
docker compose up -d openclaw-gateway
If build fails with Killed or exit code 137 during pnpm install --frozen-lockfile, the VM is out of memory. Use a larger machine class before retrying. Verify binaries: 
docker compose exec openclaw-gateway which gog
docker compose exec openclaw-gateway which goplaces
docker compose exec openclaw-gateway which wacli
Expected output: 
/usr/local/bin/gog
/usr/local/bin/goplaces
/usr/local/bin/wacli
Verify Gateway: 
docker compose logs -f openclaw-gateway
Expected output: 
[gateway] listening on ws://0.0.0.0:18789

What persists where

龙虾AI runs in Docker, but Docker is not the source of truth. All long-lived state must survive restarts, rebuilds, and reboots.
