How to run a script as root in Jenkins?
@Igor Chubin's answer is 100% correct, but never open sudoer file with a normal editor. always use visudo
just type
sudo visudothis will take you to /etc/sudoers and upon saving it will make sure that there is no error in formatting.
if you make an error in sudoer file, you will lose sudo access, so always use visudo
I do realise I'm late to the party on this question, but for reference sake I thought I'd throw my 2c in here: I use the SSH plugin for Jenkins to accomplish this (simply configure a localhost target). In this way, I can contain the script directly within Jenkins (like a normal "Execute shell" step), instead of using sudo to invoke an external script.
