ansible-role-nvidia-driver

An Ansible role to install the NVIDIA driver from the NVIDIA CUDA repositories.

Requirements

In the process of installing the NVIDIA driver, this role will reboot the nodes where it runs. Because of this, we strongly recommend that you run ansible-playbook from a separate node than the GPU nodes where you are installing the driver.

If you attempt to run Ansible on the same node where you are installing the driver, this role will either:

Refuse to proceed with an error like Running reboot with local connection would reboot the control node (if running with the local connection)
Reboot the node you're running on, interrupting the playbook execution! (if running the an ssh connection against localhost)

Installing

This role can be installed using Ansible Galaxy:

$ ansible-galaxy install nvidia.nvidia_driver
