| Deploy OpenClaw Gateway to a Kubernetes cluster with Kustomize |
|
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.)
kubectlconnected to your cluster- An API key for at least one model provider
Quick start
# 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:
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:
./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)
# 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
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
kubectl port-forward svc/openclaw 18789:18789 -n openclaw
open http://localhost:18789
What gets deployed
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:
./scripts/k8s/deploy.sh
Gateway config
Edit openclaw.json in scripts/k8s/manifests/configmap.yaml. See Gateway configuration for the full reference.
Add providers
Re-run with additional keys exported:
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:
kubectl patch secret openclaw-secrets -n openclaw \
-p '{"stringData":{"<PROVIDER>_API_KEY":"..."}}'
kubectl rollout restart deployment/openclaw -n openclaw
Custom namespace
OPENCLAW_NAMESPACE=my-namespace ./scripts/k8s/deploy.sh
Custom image
Edit the image field in scripts/k8s/manifests/deployment.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.yamlfromloopbackto 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
./scripts/k8s/deploy.sh
This applies all manifests and restarts the pod to pick up any config or secret changes.
Teardown
./scripts/k8s/deploy.sh --delete
For the default openclaw namespace, this deletes the namespace and everything in it, including the PVC.
For a custom namespace, --delete removes only OpenClaw resources and preserves the namespace and unrelated workloads:
OPENCLAW_NAMESPACE=my-namespace ./scripts/k8s/deploy.sh --delete
Use --delete-resources to request this scoped teardown explicitly in any namespace. Both scoped modes delete the OpenClaw Deployment, Service, PVC, ConfigMap, and generated Secret. Deleting the PVC removes OpenClaw's claim and access to its persisted data; whether the backing volume and data are deleted depends on the PersistentVolume or StorageClass reclaim policy (Delete or Retain).
To delete a custom namespace and every workload in it, explicitly opt in:
OPENCLAW_NAMESPACE=my-namespace ./scripts/k8s/deploy.sh --delete-namespace
This also deletes unrelated workloads and 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: ALLcapabilities, non-root user (UID 1000). - The default config keeps the Control UI on the safer local-access path: loopback bind plus
kubectl port-forwardtohttp://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.
