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.

Cmnd alias specification

User privilege specification

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!
