+# Volume Support for Knative services
+
+By default Serving supports the mounting the [volume types](https://kubernetes.io/docs/concepts/storage/volumes): `emptyDir`, `secret`, `configMap` and `projected`. [PersistentVolumes](https://kubernetes.io/docs/concepts/storage/persistent-volumes/) are supported but require a [feature flag](../configuration/feature-flags.md) to be enabled.
+
+!!! warning
+    Mounting large volumes may add considerable overhead to the application's start up time.
+
+
+Here is an example of using a persistent volume claim with a Knative Service:
+
+```yaml
+apiVersion: serving.knative.dev/v1
+kind: Service
+...
+spec:
+  template:
+    spec:
+      containers:
+          ...
+          volumeMounts:
+            - mountPath: /data
+              name: mydata
+              readOnly: false
+      volumes:
+        - name: mydata
+          persistentVolumeClaim:
+            claimName: knative-pv-claim
+            readOnly: false
+---
+apiVersion: v1
+kind: PersistentVolumeClaim
+metadata:
+  name: knative-pv-claim
+spec:
+  accessModes:
+    - ReadWriteOnce
+  resources:
+    requests:
+      storage: 1Gi
