+# intel-gpu-plugin helm chart
+
+This is a helm chart that will deploy [intel-gpu-plugin](https://github.com/intel/intel-device-plugins-for-kubernetes/blob/master/cmd/gpu_plugin) as a DaemonSet.
+
+The GPU plugin facilitates offloading the processing of computation intensive workloads to GPU hardware.
+
+## TL;DR
+
+```shell
+helm repo add k8s-at-home https://k8s-at-home.com/charts/
+helm install k8s-at-home/intel-gpu-plugin
+```
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```shell
+helm install my-release k8s-at-home/intel-gpu-plugin
+```
+
+## Uninstalling the Chart
+
+To uninstall/delete the `my-release` deployment:
+
+```shell
+helm delete my-release --purge
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Configuration
+
+The following tables lists the configurable parameters of the Sentry chart and their default values.
+Read through the [values.yaml](https://github.com/k8s-at-home/charts/blob/master/charts/intel-gpu-plugin/values.yaml) file. It has several commented out suggested values.
+
+| Parameter                                   | Description                                                                                  | Default                                               |
+| ------------------------------------------- | -------------------------------------------------------------------------------------------- | ----------------------------------------------------- |
+| `image.repository`                          | Image repository                                                                             | `intel/intel-gpu-plugin` |
+| `image.tag`                                 | Image tag. Possible values listed [here](https://hub.docker.com/r/intel/intel-gpu-plugin/tags).     | `0.18.1`                         |
+| `image.pullPolicy`                          | Image pull policy                                                                            | `IfNotPresent`                                        |
+| `strategyType`                              | Specifies the strategy used to replace old Pods by new ones                                  | `Recreate`                                            |
+| `podAnnotations`                            | Key-value pairs to add as pod annotations                                                    | `{}`                                                  |
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```shell
+helm install my-release \
+  --set image.pullPolicy="Always" \
+    k8s-at-home/intel-gpu-plugin
+```
+
+Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
+
+```shell
+helm install my-release -f values.yaml k8s-at-home/intel-gpu-plugin
+```
+
+### Node Feature Discovery
+
+If your cluster runs [Node Feature Discovery](https://github.com/k8s-at-home/charts/blob/master/charts/node-feature-discovery), you can deploy the device plugin only on nodes with Intel GPU by specifying the desired `nodeSelector` or `affinity` in your values. For example (make sure to update to your exact feature label):
+
+```yaml
+affinity:
+  nodeAffinity:
+    requiredDuringSchedulingIgnoredDuringExecution:
+      nodeSelectorTerms:
+        - matchExpressions:
+            - key: feature.node.kubernetes.io/pci-0300_8086.present
+              operator: In
+              values:
+                - "true"
+```
