Peter Steinberger f7d7148cf0 docs: rewrite published docs grounded in current source (#100142)
Source-grounded rewrite of 529 published docs pages with per-unit information-loss verification: 1,713 factual corrections cited to src/**, generated surfaces regenerated, frontmatter titles preserved for i18n, release notes pages untouched. All docs gates green.

summary: "Deploy OpenClaw Gateway to a Kubernetes cluster with Kustomize"
read_when:
- You want to run OpenClaw on a Kubernetes cluster
- You want to test OpenClaw in a Kubernetes environment
title: "Kubernetes"
---
A minimal starting point for running OpenClaw on Kubernetes, not a production-ready deployment. It covers the core resources and is meant to be adapted to your environment.
## Why not Helm
OpenClaw is a single container with some config files. The interesting customization is in agent content (Markdown files, skills, config overrides), not infrastructure templating. Kustomize handles overlays without the overhead of a Helm chart. Layer a Helm chart on top of these manifests if your deployment grows more complex.
## What you need
- A running Kubernetes cluster (AKS, EKS, GKE, k3s, kind, OpenShift, etc.)
- `kubectl` connected to your cluster
- An API key for at least one model provider
## Quick start
```bash
# Replace with your provider: ANTHROPIC, GEMINI, OPENAI, or OPENROUTER
export <PROVIDER>_API_KEY="..."
./scripts/k8s/deploy.sh
kubectl port-forward svc/openclaw 18789:18789 -n openclaw
open http://localhost:18789
```
`deploy.sh` creates token auth by default. Retrieve the generated gateway token for the Control UI:
```bash
kubectl get secret openclaw-secrets -n openclaw -o jsonpath='{.data.OPENCLAW_GATEWAY_TOKEN}' | base64 -d
```
For local debugging, `./scripts/k8s/deploy.sh --show-token` prints the token after deploy.
## Local testing with Kind
If you do not have a cluster, create one locally with [Kind](https://kind.sigs.k8s.io/):
```bash
./scripts/k8s/create-kind.sh # auto-detects docker or podman
./scripts/k8s/create-kind.sh --delete # tear down
```
Then deploy as usual with `./scripts/k8s/deploy.sh`.
## Step by step
### 1) Deploy
**Option A: API key in environment (one step)**
```bash
# Replace with your provider: ANTHROPIC, GEMINI, OPENAI, or OPENROUTER
export <PROVIDER>_API_KEY="..."
./scripts/k8s/deploy.sh
```
The script creates a Kubernetes Secret with the API key and an auto-generated gateway token, then deploys. If the Secret already exists, it preserves the current gateway token and any provider keys not being changed.
**Option B: create the secret separately**
```bash
export <PROVIDER>_API_KEY="..."
./scripts/k8s/deploy.sh --create-secret
./scripts/k8s/deploy.sh
```
Add `--show-token` to either command to print the token to stdout for local testing.
### 2) Access the gateway
```bash
kubectl port-forward svc/openclaw 18789:18789 -n openclaw
open http://localhost:18789
```
## What gets deployed
```text
Namespace: openclaw (configurable via OPENCLAW_NAMESPACE)
├── Deployment/openclaw # Single pod, init container + gateway
├── Service/openclaw # ClusterIP on port 18789
├── PersistentVolumeClaim # 10Gi for agent state and config
├── ConfigMap/openclaw-config # openclaw.json + AGENTS.md
└── Secret/openclaw-secrets # Gateway token + API keys
```
## Customization
### Agent instructions
Edit the `AGENTS.md` in `scripts/k8s/manifests/configmap.yaml` and redeploy:
```bash
./scripts/k8s/deploy.sh
```
### Gateway config
Edit `openclaw.json` in `scripts/k8s/manifests/configmap.yaml`. See [Gateway configuration](/gateway/configuration) for the full reference.
### Add providers
Re-run with additional keys exported:
```bash
export ANTHROPIC_API_KEY="..."
export OPENAI_API_KEY="..."
./scripts/k8s/deploy.sh --create-secret
./scripts/k8s/deploy.sh
```
Existing provider keys stay in the Secret unless you overwrite them.
Or patch the Secret directly:
```bash
kubectl patch secret openclaw-secrets -n openclaw \
-p '{"stringData":{"<PROVIDER>_API_KEY":"..."}}'
kubectl rollout restart deployment/openclaw -n openclaw
```
### Custom namespace
```bash
OPENCLAW_NAMESPACE=my-namespace ./scripts/k8s/deploy.sh
```
### Custom image
Edit the `image` field in `scripts/k8s/manifests/deployment.yaml`:
```yaml
image: ghcr.io/openclaw/openclaw:slim # primary; official Docker Hub mirror: openclaw/openclaw
```
### Expose beyond port-forward
The default manifests bind the gateway to loopback inside the pod. That works with `kubectl port-forward`, but not with a Kubernetes `Service` or Ingress path that needs to reach the pod IP directly.
To expose the gateway through an Ingress or load balancer:
- Change the gateway bind in `scripts/k8s/manifests/configmap.yaml` from `loopback` to a non-loopback bind that matches your deployment model.
- Keep gateway auth enabled and use a proper TLS-terminated entrypoint.
- Configure the Control UI for remote access using the supported web security model (for example HTTPS/Tailscale Serve and explicit allowed origins when needed).
## Re-deploy
```bash
./scripts/k8s/deploy.sh
```
This applies all manifests and restarts the pod to pick up any config or secret changes.
## Teardown
```bash
./scripts/k8s/deploy.sh --delete
```
This deletes the namespace and all resources in it, including the PVC.
## Architecture notes
- The gateway binds to loopback inside the pod by default, so the included setup is for `kubectl port-forward`.
- No cluster-scoped resources; everything lives in a single namespace.
- Security hardening: `readOnlyRootFilesystem`, `drop: ALL` capabilities, non-root user (UID 1000).
- The default config keeps the Control UI on the safer local-access path: loopback bind plus `kubectl port-forward` to `http://127.0.0.1:18789`.
- If you move beyond localhost access, use the supported remote model: HTTPS/Tailscale plus the appropriate gateway bind and Control UI origin settings.
- Secrets are generated in a temp directory and applied directly to the cluster; no secret material is written to the repo checkout.
