Jenkins running tomcat8 sudo: no tty present and no askpass program specified with NOPASSWD

Question

Trying to execute a sudo command from my Jenkins executor, I get the title error.

On the host machine(executor) I have configured the sudoers file to contain this line: jenkins ALL=(ALL) NOPASSWD: ALL at the very end.

The command which I am trying to run is sudo service tomcat8 restart.

Checking the available answers I got all I need or am I missing something?

There might be an issue with your sudo setup. Did you use visudo? Does the same setup work for other users? Can you give it a try manually? — C-Otto, Aug 16 '17 at 08:25
Running the same command directly from the machine as the Jenkins user work without prompting for any pwd... — Jacob, Aug 16 '17 at 08:29

There might be a workaround: As Barmar pointed out in a comment to the post "Use sudo without password INSIDE a script", it is possible to allow a dedicated script be executed by a sudoer. Assume you have a line

 jenkins ALL=(ALL) NOPASSWD:/path/to/restart.sh

this means that Jenkins can do sudo /path/to/restart.sh without a password.

If you now put your command service tomcat8 restart in restart.sh, a sudo /path/to/restart.sh should do the job.

Try turning off requiretty for the jenkins user. I would recommend using command aliases in your sudoers file as well.

Cmnd_Alias RESTART_TOMCAT = /sbin/service tomcat8 *, /etc/init.d/tomcat8 *

Defaults:jenkins !requiretty

jenkins  ALL=(root) NOPASSWD: RESTART_TOMCAT

Jenkins running tomcat8 sudo: no tty present and no askpass program specified with NOPASSWD
