How to set INSTALL_K3S_EXEC?

[FlappiTomic]

Hello,

I'd like to set INSTALL_K3S_EXEC to customize k3s, specifically INSTALL_K3S_EXEC="--tls-san x.x.x.x" to let others connecting to the k3s cluster created by Rancher Desktop.
I tried putting into override.yaml at ~/Library/Application Support/rancher-desktop/lima/_config/override.yaml but did not work.
Here is my override.yaml:

env:
  INSTALL_K3S_EXEC: --tls-san x.x.x.x

I also tried with:

provision:
  - mode: system
    script: |
      #!/bin/sh
      echo "INSTALL_K3S_EXEC=\"--tls-san x.x.x.x\"" > /etc/environment

Did not work out either.

I wonder what is the proper way to set this? I read in the repo that there is a K3S_EXEC but I think it is for k3s post installation, not for the install itself. INSTALL_K3S_EXEC is what suggested by official k3s documentation.

After spending a whole day looking for answers, this is the correct syntax that works:

env:
  K3S_EXEC: --tls-san x.x.x.x

I suggest making some document changes indicating above is the correct way to add k3s customization in the provisioning script. Current document is not helpful at all at https://docs.rancherdesktop.io/how-to-guides/provisioning-scripts which is not indicating k3s customization although a line says scripts can be used to provide certain command line parameters to K3s.

Also I suggest to align with official k3s environment variable, see https://docs.k3s.io/installation/configuration, they all use INSTALL_K3S_EXEC , it is rather confusing for rancher desktop to use K3S_EXEC.

Above doc enhancement will greatly help others who encounter this same issue. Thanks.

Thank you for the suggestion! I've filed a docs bug to see if we can improve the documentation.
