Renew NVIDIA GRID License for ACK vGPU Nodes - Container Service for Kubernetes

ACK clusters that include vGPU-accelerated nodes require both an NVIDIA GRID license and a running GRID license server. This topic describes how to renew the NVIDIA driver license on a vGPU-accelerated node.

Prerequisites

Before you begin, ensure that you have:

An NVIDIA driver license. To purchase one, see the NVIDIA Enterprise Registration portal
A running GRID license server. For setup instructions, see the NVIDIA official website
A vGPU-accelerated Elastic Compute Service (ECS) instance

Supported cluster types: dedicated clusters, managed clusters, and professional clusters.

Renew the NVIDIA driver license

After the GRID license server is running, complete the following steps on each vGPU-accelerated node.

Log on to the vGPU-accelerated node.
- For Linux instances: Connect to a Linux instance by using password authentication
- For Windows instances: Connect to a Windows instance by using password authentication

Open /etc/nvidia/gridd.conf and set the following parameters:

ServerAddress=<your license server address>
ServerPort=<license server port>

Parameter	Description
`ServerAddress`	The address of your GRID license server
`ServerPort`	The port on which the license server listens

Restart the NVIDIA driver:

systemctl daemon-reload
systemctl restart nvidia-gridd

Verify that the license is active:
```
nvidia-smi
```
If nvidia-smi runs successfully, the NVIDIA driver license of the vGPU-accelerated node is renewed.
