Bash script sudo password

[satbobo]

Hi everybody,
I want to create I script to update a small cluster of computers to install software and perform several tasks.
Sometimes it happens that I need to call commands with admin rights but of course in that case I need to prompt the password.
Since I'd like to automate the all process I am wondering if there is a way to input the sudo password from a file or if there exist other workarounds.
Thanks in advance

The traditional way is to use public-private key authentication:
