### Method 2: Kustomize

Install using Kubernetes manifests:

```bash
kubectl apply -k 'https://github.com/kagenti/mcp-gateway/config/install?ref=main'
```

This provides the same components as Helm but with less configuration flexibility.

### Method 3: Standalone Installation (Advanced)

For non-Kubernetes deployments or advanced use cases, see [Standalone Installation Guide](./binary-install.md).

- Check that Gateway API CRDs are installed: `kubectl get crd gateways.gateway.networking.k8s.io`
- Ensure Istio is installed: `kubectl get pods -n istio-system`

### Kustomize Installation Fails

**Symptom**: `kubectl apply -k` fails with validation errors

```bash
# Verify Gateway API CRDs exist
kubectl get crd gateways.gateway.networking.k8s.io httproutes.gateway.networking.k8s.io

# Check for resource conflicts
kubectl get mcpserver -A
kubectl get deployment -n mcp-system
```

**Solutions**:
- Install Gateway API CRDs first: `kubectl apply -f https://github.com/kubernetes-sigs/gateway-api/releases/download/v1.2.1/standard-install.yaml`
- Delete existing resources if upgrading: `kubectl delete -k 'https://github.com/kagenti/mcp-gateway/config/install?ref=main'`

### Pods Not Starting

**Symptom**: MCP Gateway pods stuck in `Pending`, `CrashLoopBackOff`, or `ImagePullBackOff`
