I wanted a script running as a non-root user to be able to restart a systemd service on my Ubuntu machine without needing a password.
I figured out how to do that by adding the following line to the sudoers file, which can be edited as root using the visudo command:
# dogsheep user can restart datasette service
dogsheep ALL = (root) NOPASSWD: /usr/bin/systemctl restart datasette
Having added this line, my dogsheep user account could now run the following:
$ sudo /usr/bin/systemctl restart datasette
But if it tries to run the command with any other arguments it gets prompted for a password:
$ sudo /usr/bin/systemctl restart datasette2
[sudo] password for dogsheep:
