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

Question

I spend several days setting up the file /etc/sudoers to be able to give permissions to root to the user jenkins. I have Jenkins installed on my server

Answer 1

This is just a response to elaborate on the steps to take to fix the issue.

First thing, figure out which user Jenkins GUI is using to execute the bash shell script.

select the project > Configure > enter whoami in the executable shell > save and Build Now. View result in build history > click console output

User may be tomcat or jenkins or whatever.

SSH into Jenkins server

1. sudo su
2. visudo
3. tomcat ALL=(ALL) NOPASSWD: ALL #if user displayed is tomcat

Answer 2

This is quite possible that you are adding a wrong user to the sudoers file. This happened to me as well and the solution to add an entry in sudoers file wasn't working for me. You will need to know the actual user that your jenkins is using to execute commands. For this purpose you can add a build step (Execute shell) within your jenkins with the following command:

whoami

Then try running the jenkins job again and in the console output, you will see the user that jenkins is using to execute commands. You will then need to add this user to your sudoers file. For example if the user was 'tomcat', you will add the following line to the end of your sudoers file:

tomcat ALL=(ALL) NOPASSWD: ALL

I've tested the solution described by @Jayan in the comments of the question. You must include the new line at the end of the file:

# 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.
