K3sup script fail requiring a password. #19

I am testing the install script but using unraid as the hypervisor rather than proxmox. AFAIK this should make a difference, it just changes the creation of the base vms.

The issue I'm seeing is:

sudo: a terminal is required to read the password; either use the -S option to read from standard input or configure an askpass helper
sudo: a password is required

This is returned when the install part of the script runs (ie # Step 1: Bootstrap First k3s Node). Looking at the issue here it appears that sudo is a requirement for K3sup. this would mean the script shouldn't work, but it obviously does. what am I missing?

Are you using certificate based authentication for SSH or standard passwords? You should use certificates for this script (AKA keys).

cloud-init on Proxmox sets ssh NOPASSWD in /etc/sudoers.d/. This is needed for the script to run without asking for the password. You also need to setup the certificate based authentication for SSH

on the Unraid VM create a new file in /etc/sudoers.d/ (90-cloud-init-users)
add YOURUSERNAME ALL=(ALL) NOPASSWD:ALL
set permissions chmod 0444 90-cloud-init-users

WARNING doing this will disable the sudo password for the user.

That makes sense. I'm not running on proxmox so didn't use the cloud-init process. Will try this
