How to solve "sudo: no tty present and no askpass program specified" when trying to run a shell from Jenkins

gistfile1.txt

Running shell scripts that have contain sudo commands in them from jenkins might not run as expected. To fix this, follow along
Simple steps:
1. On ubuntu based systems, run " $ sudo visudo "
2. this will open /etc/sudoers file.
3. If your jenkins user is already in that file, then modify to look like this:

jenkins ALL=(ALL) NOPASSWD: ALL
4. save the file by doing Ctrl+O  (dont save in tmp file. save in /etc/sudoers, confirm overwrite)
5. Exit by doing Ctrl+X
6. Relaunch your jenkins job 
7. you shouldnt see that error message again :)

Thanks so much!

In response to the question asked here:

On linux you can bypass sudo prompt using:

echo <password> | sudo -S whoami

Pass the formatted command to subprocess and you are good to go:

import subprocess as sp

cmd = "whoami"
password= "<password>"

stdout, stderr = sp.Popen("echo {} | sudo -S {}".format(password, cmd), shell=True, stdout=sp.PIPE, stderr=sp.PIPE).communicate()

print(stdout.decode())

if stderr:
    print("error occured:")
    print(stderr.decode())

It should print root as command is executed by sudo user.

thanks....
