As you mentioned you can see the script in template, I would recommend you to check in the console and check if your script is visible, if yes check the serial console to check why your script is not running. It might due to typo or due to missing the confirmation/consent.

To reproduce your issue I am following the documentation now set my main.tf as below:

  metadata_startup_script = "${file("file-name-with-full-path")}"

In that file i set my startup script as below:

#! /bin/bash
………...
sudo apt update
wait 60
sudo apt install apache2 -y
wait 60
sudo systemctl start apache2
wait 60
sudo systemctl status apache2

After creating the vm i can see the apache is running in my instance.

$ sudo systemctl status apache2

I t is related to my text editor I used VSC so I usethis way because VSC which can not read,Even if you have a single CRLF in the file, the above setting will be ignored and the whole file will be converted to CRLF. You first need to convert all CRLF into LF before you can open it in Visual Studio Code.
