How to run sudo command with no password?
I found that the most straight forward thing to do, in order to easily replicate this behavior across multiple servers, was the following:
sudo visudo
Change this line:
Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL
to this line:
Members of the admin group may gain root privileges
%admin ALL=(ALL) NOPASSWD:ALL
And move it under this line:
Allow members of group sudo to execute any command
%sudo ALL=(ALL:ALL) ALL
you should now have this:
This file MUST be edited with the 'visudo' command as root.
Please consider adding local content in /etc/sudoers.d/ instead of
directly modifying this file.
See the man page for details on how to write a sudoers file.

root ALL=(ALL:ALL) ALL
Allow members of group sudo to execute any command
%sudo ALL=(ALL:ALL) ALL
Members of the admin group may gain root privileges
%admin ALL=(ALL) NOPASSWD:ALL
See sudoers(5) for more information on "#include" directives:
#includedir /etc/sudoers.d
then for every user that needs sudo access WITH a password:
sudo adduser <\user> sudo
and for every user that needs sudo access WITH NO password:
sudo adduser <\user> admin
and finally, run this:
sudo service sudo restart
And that's it!
