<p>Using <a href="https://kubectl.docs.kubernetes.io/pages/app_management/apply.html#usage" rel="noreferrer"><code>kubectl apply -k</code></a>, you can overlay <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/sig-architecture/api-conventions.md#resources" rel="noreferrer">Resource</a> configs (that you have already defined). Can you create resources as well?</p>

<p>In my specific case I want to create a <a href="https://kubernetes.io/docs/concepts/storage/volumes/#local" rel="noreferrer">local Volume</a> for the development environment. I do not have this Resource in the base folder though. </p>

<p>My folder structure is like this:</p>

<blockquote>
<pre><code>~/someApp
├── base
│   ├── deployment.yaml
│   ├── kustomization.yaml
│   └── service.yaml
└── overlays
    ├── development
    │   ├── cpu_count.yaml
    │   ├── kustomization.yaml
    │   ├── replica_count.yaml
    │   └── volume.yaml &lt;--- *Is this possible*?
    └── production
        ├── cpu_count.yaml
        ├── kustomization.yaml
        └── replica_count.yaml
</code></pre>
</blockquote>

<p>In your <code>overlays/development/kustomization.yaml</code> you can add:</p>

<pre><code>resources:
  - volume.yaml
</code></pre>
