Anandesh Sharma 61ef76edb5 docs(gateway): document Docker bridge networking and loopback bind caveat (#28001)
* docs(gateway): document Docker bridge networking and loopback bind caveat

The default loopback bind makes the gateway unreachable with Docker
bridge networking because port-forwarded traffic arrives on eth0, not
lo. Add a note in both the Dockerfile and the configuration reference
explaining the workarounds (--network host or bind: lan).

Fixes #27950

summary: "Optional Docker-based setup and onboarding for OpenClaw"
read_when:
- You want a containerized gateway instead of local installs
- You are validating the Docker flow
title: "Docker"
---
# Docker (optional)
Docker is **optional**. Use it only if you want a containerized gateway or to validate the Docker flow.
## Is Docker right for me?
- **Yes**: you want an isolated, throwaway gateway environment or to run OpenClaw on a host without local installs.
- **No**: youre running on your own machine and just want the fastest dev loop. Use the normal install flow instead.
- **Sandboxing note**: agent sandboxing uses Docker too, but it does **not** require the full gateway to run in Docker. See [Sandboxing](/gateway/sandboxing).
This guide covers:
- Containerized Gateway (full OpenClaw in Docker)
- Per-session Agent Sandbox (host gateway + Docker-isolated agent tools)
Sandboxing details: [Sandboxing](/gateway/sandboxing)
## Requirements
- Docker Desktop (or Docker Engine) + Docker Compose v2
- At least 2 GB RAM for image build (`pnpm install` may be OOM-killed on 1 GB hosts with exit 137)
- Enough disk for images + logs
## Containerized Gateway (Docker Compose)
### Quick start (recommended)
<Note>
Docker defaults here assume bind modes (`lan`/`loopback`), not host aliases. Use bind
mode values in `gateway.bind` (for example `lan` or `loopback`), not host aliases like
`0.0.0.0` or `localhost`.
</Note>
From repo root:
```bash
./docker-setup.sh
```
This script:
- builds the gateway image locally (or pulls a remote image if `OPENCLAW_IMAGE` is set)
- runs the onboarding wizard
- prints optional provider setup hints
- starts the gateway via Docker Compose
- generates a gateway token and writes it to `.env`
Optional env vars:
- `OPENCLAW_IMAGE` — use a remote image instead of building locally (e.g. `ghcr.io/openclaw/openclaw:latest`)
- `OPENCLAW_DOCKER_APT_PACKAGES` — install extra apt packages during build
- `OPENCLAW_EXTRA_MOUNTS` — add extra host bind mounts
- `OPENCLAW_HOME_VOLUME` — persist `/home/node` in a named volume
After it finishes:
- Open `http://127.0.0.1:18789/` in your browser.
- Paste the token into the Control UI (Settings → token).
- Need the URL again? Run `docker compose run --rm openclaw-cli dashboard --no-open`.
### Automation/CI (non-interactive, no TTY noise)
For scripts and CI, disable Compose pseudo-TTY allocation with `-T`:
```bash
docker compose run -T --rm openclaw-cli gateway probe
docker compose run -T --rm openclaw-cli devices list --json
```
If your automation exports no Claude session vars, leaving them unset now resolves to
empty values by default in `docker-compose.yml` to avoid repeated "variable is not set"
warnings.
### Shared-network security note (CLI + gateway)
`openclaw-cli` uses `network_mode: "service:openclaw-gateway"` so CLI commands can
reliably reach the gateway over `127.0.0.1` in Docker.
Treat this as a shared trust boundary: loopback binding is not isolation between these two
containers. If you need stronger separation, run commands from a separate container/host
network path instead of the bundled `openclaw-cli` service.
To reduce impact if the CLI process is compromised, the compose config drops
`NET_RAW`/`NET_ADMIN` and enables `no-new-privileges` on `openclaw-cli`.
It writes config/workspace on the host:
- `~/.openclaw/`
- `~/.openclaw/workspace`
Running on a VPS? See [Hetzner (Docker VPS)](/install/hetzner).
### Use a remote image (skip local build)
Official pre-built images are published at:
- [GitHub Container Registry package](https://github.com/openclaw/openclaw/pkgs/container/openclaw)
Use image name `ghcr.io/openclaw/openclaw` (not similarly named Docker Hub
images).
Common tags:
- `main` — latest build from `main`
- `<version>` — release tag builds (for example `2026.2.26`)
- `latest` — latest stable release tag
### Base image metadata
The main Docker image currently uses:
- `node:22-bookworm`
The docker image now publishes OCI base-image annotations (sha256 is an example):
- `org.opencontainers.image.base.name=docker.io/library/node:22-bookworm`
- `org.opencontainers.image.base.digest=sha256:cd7bcd2e7a1e6f72052feb023c7f6b722205d3fcab7bbcbd2d1bfdab10b1e935`
- `org.opencontainers.image.source=https://github.com/openclaw/openclaw`
- `org.opencontainers.image.url=https://openclaw.ai`
- `org.opencontainers.image.documentation=https://docs.openclaw.ai/install/docker`
- `org.opencontainers.image.licenses=MIT`
- `org.opencontainers.image.title=OpenClaw`
- `org.opencontainers.image.description=OpenClaw gateway and CLI runtime container image`
- `org.opencontainers.image.revision=<git-sha>`
- `org.opencontainers.image.version=<tag-or-main>`
- `org.opencontainers.image.created=<rfc3339 timestamp>`
Reference: [OCI image annotations](https://github.com/opencontainers/image-spec/blob/main/annotations.md)
Release context: this repository's tagged history already uses Bookworm in
`v2026.2.22` and earlier 2026 tags (for example `v2026.2.21`, `v2026.2.9`).
By default the setup script builds the image from source. To pull a pre-built
image instead, set `OPENCLAW_IMAGE` before running the script:
```bash
export OPENCLAW_IMAGE="ghcr.io/openclaw/openclaw:latest"
./docker-setup.sh
```
The script detects that `OPENCLAW_IMAGE` is not the default `openclaw:local` and
runs `docker pull` instead of `docker build`. Everything else (onboarding,
gateway start, token generation) works the same way.
`docker-setup.sh` still runs from the repository root because it uses the local
`docker-compose.yml` and helper files. `OPENCLAW_IMAGE` skips local image build
time; it does not replace the compose/setup workflow.
### Shell Helpers (optional)
For easier day-to-day Docker management, install `ClawDock`:
```bash
mkdir -p ~/.clawdock && curl -sL https://raw.githubusercontent.com/openclaw/openclaw/main/scripts/shell-helpers/clawdock-helpers.sh -o ~/.clawdock/clawdock-helpers.sh
```
**Add to your shell config (zsh):**
```bash
echo 'source ~/.clawdock/clawdock-helpers.sh' >> ~/.zshrc && source ~/.zshrc
```
Then use `clawdock-start`, `clawdock-stop`, `clawdock-dashboard`, etc. Run `clawdock-help` for all commands.
See [`ClawDock` Helper README](https://github.com/openclaw/openclaw/blob/main/scripts/shell-helpers/README.md) for details.
### Manual flow (compose)
```bash
docker build -t openclaw:local -f Dockerfile .
docker compose run --rm openclaw-cli onboard
docker compose up -d openclaw-gateway
```
Note: run `docker compose ...` from the repo root. If you enabled
`OPENCLAW_EXTRA_MOUNTS` or `OPENCLAW_HOME_VOLUME`, the setup script writes
`docker-compose.extra.yml`; include it when running Compose elsewhere:
```bash
docker compose -f docker-compose.yml -f docker-compose.extra.yml <command>
```
### Control UI token + pairing (Docker)
If you see “unauthorized” or “disconnected (1008): pairing required”, fetch a
fresh dashboard link and approve the browser device:
```bash
docker compose run --rm openclaw-cli dashboard --no-open
docker compose run --rm openclaw-cli devices list
docker compose run --rm openclaw-cli devices approve <requestId>
```
More detail: [Dashboard](/web/dashboard), [Devices](/cli/devices).
### Extra mounts (optional)
If you want to mount additional host directories into the containers, set
`OPENCLAW_EXTRA_MOUNTS` before running `docker-setup.sh`. This accepts a
comma-separated list of Docker bind mounts and applies them to both
`openclaw-gateway` and `openclaw-cli` by generating `docker-compose.extra.yml`.
Example:
```bash
export OPENCLAW_EXTRA_MOUNTS="$HOME/.codex:/home/node/.codex:ro,$HOME/github:/home/node/github:rw"
./docker-setup.sh
```
Notes:
- Paths must be shared with Docker Desktop on macOS/Windows.
- Each entry must be `source:target[:options]` with no spaces, tabs, or newlines.
- If you edit `OPENCLAW_EXTRA_MOUNTS`, rerun `docker-setup.sh` to regenerate the
extra compose file.
- `docker-compose.extra.yml` is generated. Dont hand-edit it.
### Persist the entire container home (optional)
If you want `/home/node` to persist across container recreation, set a named
volume via `OPENCLAW_HOME_VOLUME`. This creates a Docker volume and mounts it at
`/home/node`, while keeping the standard config/workspace bind mounts. Use a
named volume here (not a bind path); for bind mounts, use
`OPENCLAW_EXTRA_MOUNTS`.
Example:
```bash
export OPENCLAW_HOME_VOLUME="openclaw_home"
./docker-setup.sh
```
You can combine this with extra mounts:
```bash
export OPENCLAW_HOME_VOLUME="openclaw_home"
export OPENCLAW_EXTRA_MOUNTS="$HOME/.codex:/home/node/.codex:ro,$HOME/github:/home/node/github:rw"
./docker-setup.sh
```
Notes:
- Named volumes must match `^[A-Za-z0-9][A-Za-z0-9_.-]*$`.
- If you change `OPENCLAW_HOME_VOLUME`, rerun `docker-setup.sh` to regenerate the
extra compose file.
- The named volume persists until removed with `docker volume rm <name>`.
### Install extra apt packages (optional)
If you need system packages inside the image (for example, build tools or media
libraries), set `OPENCLAW_DOCKER_APT_PACKAGES` before running `docker-setup.sh`.
This installs the packages during the image build, so they persist even if the
container is deleted.
Example:
```bash
export OPENCLAW_DOCKER_APT_PACKAGES="ffmpeg build-essential"
./docker-setup.sh
```
Notes:
- This accepts a space-separated list of apt package names.
- If you change `OPENCLAW_DOCKER_APT_PACKAGES`, rerun `docker-setup.sh` to rebuild
the image.
### Power-user / full-featured container (opt-in)
The default Docker image is **security-first** and runs as the non-root `node`
user. This keeps the attack surface small, but it means:
- no system package installs at runtime
- no Homebrew by default
- no bundled Chromium/Playwright browsers
If you want a more full-featured container, use these opt-in knobs:
1. **Persist `/home/node`** so browser downloads and tool caches survive:
```bash
export OPENCLAW_HOME_VOLUME="openclaw_home"
./docker-setup.sh
```
2. **Bake system deps into the image** (repeatable + persistent):
```bash
export OPENCLAW_DOCKER_APT_PACKAGES="git curl jq"
./docker-setup.sh
```
3. **Install Playwright browsers without `npx`** (avoids npm override conflicts):
```bash
docker compose run --rm openclaw-cli \
node /app/node_modules/playwright-core/cli.js install chromium
```
If you need Playwright to install system deps, rebuild the image with
`OPENCLAW_DOCKER_APT_PACKAGES` instead of using `--with-deps` at runtime.
4. **Persist Playwright browser downloads**:
- Set `PLAYWRIGHT_BROWSERS_PATH=/home/node/.cache/ms-playwright` in
`docker-compose.yml`.
- Ensure `/home/node` persists via `OPENCLAW_HOME_VOLUME`, or mount
`/home/node/.cache/ms-playwright` via `OPENCLAW_EXTRA_MOUNTS`.
### Permissions + EACCES
The image runs as `node` (uid 1000). If you see permission errors on
`/home/node/.openclaw`, make sure your host bind mounts are owned by uid 1000.
Example (Linux host):
```bash
sudo chown -R 1000:1000 /path/to/openclaw-config /path/to/openclaw-workspace
```
If you choose to run as root for convenience, you accept the security tradeoff.
### Faster rebuilds (recommended)
To speed up rebuilds, order your Dockerfile so dependency layers are cached.
This avoids re-running `pnpm install` unless lockfiles change:
```dockerfile
FROM node:22-bookworm
# Install Bun (required for build scripts)
RUN curl -fsSL https://bun.sh/install | bash
ENV PATH="/root/.bun/bin:${PATH}"
RUN corepack enable
WORKDIR /app
# Cache dependencies unless package metadata changes
COPY package.json pnpm-lock.yaml pnpm-workspace.yaml .npmrc ./
COPY ui/package.json ./ui/package.json
COPY scripts ./scripts
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"]
```
### Channel setup (optional)
Use the CLI container to configure channels, then restart the gateway if needed.
WhatsApp (QR):
```bash
docker compose run --rm openclaw-cli channels login
```
Telegram (bot token):
```bash
docker compose run --rm openclaw-cli channels add --channel telegram --token "<token>"
```
Discord (bot token):
```bash
docker compose run --rm openclaw-cli channels add --channel discord --token "<token>"
```
Docs: [WhatsApp](/channels/whatsapp), [Telegram](/channels/telegram), [Discord](/channels/discord)
### OpenAI Codex OAuth (headless Docker)
If you pick OpenAI Codex OAuth in the wizard, it opens a browser URL and tries
to capture a callback on `http://127.0.0.1:1455/auth/callback`. In Docker or
headless setups that callback can show a browser error. Copy the full redirect
URL you land on and paste it back into the wizard to finish auth.
### Health check
```bash
docker compose exec openclaw-gateway node dist/index.js health --token "$OPENCLAW_GATEWAY_TOKEN"
```
### E2E smoke test (Docker)
```bash
scripts/e2e/onboard-docker.sh
```
### QR import smoke test (Docker)
```bash
pnpm test:docker:qr
```
### LAN vs loopback (Docker Compose)
`docker-setup.sh` defaults `OPENCLAW_GATEWAY_BIND=lan` so host access to
`http://127.0.0.1:18789` works with Docker port publishing.
- `lan` (default): host browser + host CLI can reach the published gateway port.
- `loopback`: only processes inside the container network namespace can reach
the gateway directly; host-published port access may fail.
The setup script also pins `gateway.mode=local` after onboarding so Docker CLI
commands default to local loopback targeting.
Legacy config note: use bind mode values in `gateway.bind` (`lan` / `loopback` /
`custom` / `tailnet` / `auto`), not host aliases (`0.0.0.0`, `127.0.0.1`,
`localhost`, `::`, `::1`).
If you see `Gateway target: ws://172.x.x.x:18789` or repeated `pairing required`
errors from Docker CLI commands, run:
```bash
docker compose run --rm openclaw-cli config set gateway.mode local
docker compose run --rm openclaw-cli config set gateway.bind lan
docker compose run --rm openclaw-cli devices list --url ws://127.0.0.1:18789
```
### Notes
- Gateway bind defaults to `lan` for container use (`OPENCLAW_GATEWAY_BIND`).
- Dockerfile CMD uses `--allow-unconfigured`; mounted config with `gateway.mode` not `local` will still start. Override CMD to enforce the guard.
- The gateway container is the source of truth for sessions (`~/.openclaw/agents/<agentId>/sessions/`).
## Agent Sandbox (host gateway + Docker tools)
Deep dive: [Sandboxing](/gateway/sandboxing)
### What it does
When `agents.defaults.sandbox` is enabled, **non-main sessions** run tools inside a Docker
container. The gateway stays on your host, but the tool execution is isolated:
- scope: `"agent"` by default (one container + workspace per agent)
- scope: `"session"` for per-session isolation
- per-scope workspace folder mounted at `/workspace`
- optional agent workspace access (`agents.defaults.sandbox.workspaceAccess`)
- allow/deny tool policy (deny wins)
- inbound media is copied into the active sandbox workspace (`media/inbound/*`) so tools can read it (with `workspaceAccess: "rw"`, this lands in the agent workspace)
Warning: `scope: "shared"` disables cross-session isolation. All sessions share
one container and one workspace.
### Per-agent sandbox profiles (multi-agent)
If you use multi-agent routing, each agent can override sandbox + tool settings:
`agents.list[].sandbox` and `agents.list[].tools` (plus `agents.list[].tools.sandbox.tools`). This lets you run
mixed access levels in one gateway:
- Full access (personal agent)
- Read-only tools + read-only workspace (family/work agent)
- No filesystem/shell tools (public agent)
See [Multi-Agent Sandbox & Tools](/tools/multi-agent-sandbox-tools) for examples,
precedence, and troubleshooting.
### Default behavior
- Image: `openclaw-sandbox:bookworm-slim`
- One container per agent
- Agent workspace access: `workspaceAccess: "none"` (default) uses `~/.openclaw/sandboxes`
- `"ro"` keeps the sandbox workspace at `/workspace` and mounts the agent workspace read-only at `/agent` (disables `write`/`edit`/`apply_patch`)
- `"rw"` mounts the agent workspace read/write at `/workspace`
- Auto-prune: idle > 24h OR age > 7d
- Network: `none` by default (explicitly opt-in if you need egress)
- `host` is blocked.
- `container:<id>` is blocked by default (namespace-join risk).
- Default allow: `exec`, `process`, `read`, `write`, `edit`, `sessions_list`, `sessions_history`, `sessions_send`, `sessions_spawn`, `session_status`
- Default deny: `browser`, `canvas`, `nodes`, `cron`, `discord`, `gateway`
### Enable sandboxing
If you plan to install packages in `setupCommand`, note:
- Default `docker.network` is `"none"` (no egress).
- `docker.network: "host"` is blocked.
- `docker.network: "container:<id>"` is blocked by default.
- Break-glass override: `agents.defaults.sandbox.docker.dangerouslyAllowContainerNamespaceJoin: true`.
- `readOnlyRoot: true` blocks package installs.
- `user` must be root for `apt-get` (omit `user` or set `user: "0:0"`).
OpenClaw auto-recreates containers when `setupCommand` (or docker config) changes
unless the container was **recently used** (within ~5 minutes). Hot containers
log a warning with the exact `openclaw sandbox recreate ...` command.
```json5
{
agents: {
defaults: {
sandbox: {
mode: "non-main", // off | non-main | all
scope: "agent", // session | agent | shared (agent is default)
workspaceAccess: "none", // none | ro | rw
workspaceRoot: "~/.openclaw/sandboxes",
docker: {
image: "openclaw-sandbox:bookworm-slim",
workdir: "/workspace",
readOnlyRoot: true,
tmpfs: ["/tmp", "/var/tmp", "/run"],
network: "none",
user: "1000:1000",
capDrop: ["ALL"],
env: { LANG: "C.UTF-8" },
setupCommand: "apt-get update && apt-get install -y git curl jq",
pidsLimit: 256,
memory: "1g",
memorySwap: "2g",
cpus: 1,
ulimits: {
nofile: { soft: 1024, hard: 2048 },
nproc: 256,
},
seccompProfile: "/path/to/seccomp.json",
apparmorProfile: "openclaw-sandbox",
dns: ["1.1.1.1", "8.8.8.8"],
extraHosts: ["internal.service:10.0.0.5"],
},
prune: {
idleHours: 24, // 0 disables idle pruning
maxAgeDays: 7, // 0 disables max-age pruning
},
},
},
},
tools: {
sandbox: {
tools: {
allow: [
"exec",
"process",
"read",
"write",
"edit",
"sessions_list",
"sessions_history",
"sessions_send",
"sessions_spawn",
"session_status",
],
deny: ["browser", "canvas", "nodes", "cron", "discord", "gateway"],
},
},
},
}
```
Hardening knobs live under `agents.defaults.sandbox.docker`:
`network`, `user`, `pidsLimit`, `memory`, `memorySwap`, `cpus`, `ulimits`,
`seccompProfile`, `apparmorProfile`, `dns`, `extraHosts`,
`dangerouslyAllowContainerNamespaceJoin` (break-glass only).
Multi-agent: override `agents.defaults.sandbox.{docker,browser,prune}.*` per agent via `agents.list[].sandbox.{docker,browser,prune}.*`
(ignored when `agents.defaults.sandbox.scope` / `agents.list[].sandbox.scope` is `"shared"`).
### Build the default sandbox image
```bash
scripts/sandbox-setup.sh
```
This builds `openclaw-sandbox:bookworm-slim` using `Dockerfile.sandbox`.
### Sandbox common image (optional)
If you want a sandbox image with common build tooling (Node, Go, Rust, etc.), build the common image:
```bash
scripts/sandbox-common-setup.sh
```
This builds `openclaw-sandbox-common:bookworm-slim`. To use it:
```json5
{
agents: {
defaults: {
sandbox: { docker: { image: "openclaw-sandbox-common:bookworm-slim" } },
},
},
}
```
### Sandbox browser image
To run the browser tool inside the sandbox, build the browser image:
```bash
scripts/sandbox-browser-setup.sh
```
This builds `openclaw-sandbox-browser:bookworm-slim` using
`Dockerfile.sandbox-browser`. The container runs Chromium with CDP enabled and
an optional noVNC observer (headful via Xvfb).
Notes:
- Headful (Xvfb) reduces bot blocking vs headless.
- Headless can still be used by setting `agents.defaults.sandbox.browser.headless=true`.
- No full desktop environment (GNOME) is needed; Xvfb provides the display.
- Browser containers default to a dedicated Docker network (`openclaw-sandbox-browser`) instead of global `bridge`.
- Optional `agents.defaults.sandbox.browser.cdpSourceRange` restricts container-edge CDP ingress by CIDR (for example `172.21.0.1/32`).
- noVNC observer access is password-protected by default; OpenClaw provides a short-lived observer token URL that serves a local bootstrap page and keeps the password in URL fragment (instead of URL query).
Use config:
```json5
{
agents: {
defaults: {
sandbox: {
browser: { enabled: true },
},
},
},
}
```
Custom browser image:
```json5
{
agents: {
defaults: {
sandbox: { browser: { image: "my-openclaw-browser" } },
},
},
}
```
When enabled, the agent receives:
- a sandbox browser control URL (for the `browser` tool)
- a noVNC URL (if enabled and headless=false)
Remember: if you use an allowlist for tools, add `browser` (and remove it from
deny) or the tool remains blocked.
Prune rules (`agents.defaults.sandbox.prune`) apply to browser containers too.
### Custom sandbox image
Build your own image and point config to it:
```bash
docker build -t my-openclaw-sbx -f Dockerfile.sandbox .
```
```json5
{
agents: {
defaults: {
sandbox: { docker: { image: "my-openclaw-sbx" } },
},
},
}
```
### Tool policy (allow/deny)
- `deny` wins over `allow`.
- If `allow` is empty: all tools (except deny) are available.
- If `allow` is non-empty: only tools in `allow` are available (minus deny).
### Pruning strategy
Two knobs:
- `prune.idleHours`: remove containers not used in X hours (0 = disable)
- `prune.maxAgeDays`: remove containers older than X days (0 = disable)
Example:
- Keep busy sessions but cap lifetime:
`idleHours: 24`, `maxAgeDays: 7`
- Never prune:
`idleHours: 0`, `maxAgeDays: 0`
### Security notes
- Hard wall only applies to **tools** (exec/read/write/edit/apply_patch).
- Host-only tools like browser/camera/canvas are blocked by default.
- Allowing `browser` in sandbox **breaks isolation** (browser runs on host).
## Troubleshooting
- Image missing: build with [`scripts/sandbox-setup.sh`](https://github.com/openclaw/openclaw/blob/main/scripts/sandbox-setup.sh) or set `agents.defaults.sandbox.docker.image`.
- Container not running: it will auto-create per session on demand.
- Permission errors in sandbox: set `docker.user` to a UID:GID that matches your
mounted workspace ownership (or chown the workspace folder).
- Custom tools not found: OpenClaw runs commands with `sh -lc` (login shell), which
sources `/etc/profile` and may reset PATH. Set `docker.env.PATH` to prepend your
custom tool paths (e.g., `/custom/bin:/usr/local/share/npm-global/bin`), or add
a script under `/etc/profile.d/` in your Dockerfile.
