How can I install NVIDIA in non-interactive by SaltStack - nvidia

Question

I'm new with SaltStack.
I need to install NVIDIA on minion server running CentOS 7 with SaltStack only.
In the gpu/init.sls file:
install_nvidia:
cmd.script:
- source: salt://gpu/files/NVIDIA-Linux-x86_64-375.20.run
- user: root
- group: root
- shell: /bin/bash
- args: -a
I run:
sudo salt minion_name state.apply gpu
I get the error:
...
stderr:
Error opening terminal: unknown.
...
...
Summary for minion_name
------------
Succeeded: 0 (changed=1)
Failed: 1
How can I get more verbose information about the reason it failed?
I believe it wait to user input but I don't know what
Also how can I install NVIDIA on CentOS 7 with non interactive way?
Thanks.

You can get more verbose information about why a Salt state has failed by running it locally using salt-call -l debug.
salt-call -l debug state.apply gpu
In your case, you have to be aware that installing the NVIDIA driver on Linux will require you to run the installer without a graphical session present. The simplest way to do this will be to check if you're currently in a graphical session (with systemd) and then drop do multi-user.target if so:
enter-multiuser:
cmd.run:
- name: systemctl isolate multi-user.target
- onlyif: systemctl status graphical.target
Then, you can install the NVIDIA driver silently using something like
gpu-prerequisites:
pkg.installed:
- pkgs:
- kernel-devel
download-installer:
file.managed:
- name: /tmp/NVIDIA-Linux-x86_64-375.20.run
- source: salt://gpu/files/NVIDIA-Linux-x86_64-375.20.run
install-driver:
cmd.run:
- name: /tmp/NVIDIA-Linux-x86_64-375.20.run -a -s -Z -X
- require:
- file: download-installer
- pkg: gpu-prequisites
start-graphical:
cmd.run:
- name: systemctl start graphical.target
- unless: systemctl status graphical.target
- watch:
- cmd: install-driver
