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

Role variables

Variable Default value Description
nvidia_driver_package_state "present" Package state for NVIDIA driver packages
nvidia_driver_package_version "" Package version to install. Note that this should match the actual version of the deb or RPM package to be installed.
nvidia_driver_persistence_mode_on yes Whether to enable persistence mode (boolean)
nvidia_driver_skip_reboot no Whether to skip rebooting the node during the install
nvidia_driver_module_file "/etc/modprobe.d/nvidia.conf" Filename to use for NVIDIA driver parameters
nvidia_driver_module_params "" Parameters to pass to the NVIDIA driver
nvidia_driver_branch "515" Default driver branch to install

nvidia_driver_rhel_cuda_repo_gpgkey "https://developer.download.nvidia.com/compute/cuda/repos/{{ _rhel_repo_dir }}/7fa2af80.pub" GPG key for the CUDA repo

Ubuntu specific variables

For Ubuntu installs, you have the choice of installing from the Canonical repositories and the NVIDIA CUDA repositories.

By default, the Canonical repositories will be used, and the driver installed will be the headless server driver.
