+Kube play supports CDI (Container Device Interface) device selectors to share
+host devices (e.g. GPUs) with containers. The configuration format follows
+Kubernetes extended resource management:
+```
+apiVersion: v1
+kind: Pod
+spec:
+  containers:
+  - name: container
+    resources:
+      limits:
+        nvidia.com/gpu=all: 1
+```
+
+To enable sharing host devices, analogous to using the `--device` flag Podman
+kube supports a custom CDI selector: `podman.io/device=<host device path>`.

 Kubernetes ConfigMap can be referred as a source of environment variables or volumes in Pods or Deployments.
