### Deploying AMD GPU device plugin
|
||||
|
||||
The [official AMD GPU device plugin](https://github.com/RadeonOpenCompute/k8s-device-plugin)
|
||||
has the following requirements:
|
||||
|
||||
- Kubernetes nodes have to be pre-installed with AMD GPU Linux driver.
|
||||
|
||||
To deploy the AMD device plugin once your cluster is running and the above
|
||||
requirements are satisfied:
|
||||
```
|
||||
# For Kubernetes v1.9
|
||||
kubectl create -f https://raw.githubusercontent.com/RadeonOpenCompute/k8s-device-plugin/r1.9/k8s-ds-amdgpu-dp.yaml
|
||||
|
||||
# For Kubernetes v1.10
|
||||
kubectl create -f https://raw.githubusercontent.com/RadeonOpenCompute/k8s-device-plugin/r1.10/k8s-ds-amdgpu-dp.yaml
|
||||
```
|
||||
Report issues with this device plugin to [RadeonOpenCompute/k8s-device-plugin](https://github.com/RadeonOpenCompute/k8s-device-plugin).
