### Description{% #description %}

StatefulSets should not define a storage request under `spec.volumeClaimTemplates[*].spec.resources.requests.storage`. This rule flags any StatefulSet that includes this field.

## Compliant Code Examples{% #compliant-code-examples %}

```yaml
#this code is a correct code for which the query should not find any result
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: web2
spec:
  serviceName: "nginx"
  replicas: 2
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: k8s.gcr.io/nginx-slim:0.8
        ports:
        - containerPort: 80
          name: web
        volumeMounts:
        - name: www
          mountPath: /usr/share/nginx/html
  volumeClaimTemplates:
  - metadata:
      name: www
    spec:
      accessModes: [ "ReadWriteOnce" ]
```

## Non-Compliant Code Examples{% #non-compliant-code-examples %}
