Deploy OpenClaw Gateway to a Kubernetes cluster with Kustomize	You want to run OpenClaw on a Kubernetes cluster You want to test OpenClaw in a Kubernetes environment	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

# 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.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

./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

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.
