Run shell scripts as root though Jenkins

I have a EC2 instance running. How can I run commands with sudo through Jenkins? When I try sudo touch /home/ec2-user/foo.bar, I get the following error: sudo: no tty present and no askpass program specified.

What am I doing wrong?

Solution 1:

By default sudo cannot be used without a TTY. In order to do so:

• Disable 'requiretty' in sudoers (using visudo)
  • This should amount to commenting out 'Defaults requiretty' (using visudo)

• Ensure that your user is able to login without entering a password:
  • Set 'NOPASSWD' in sudoers
  • Create the user if the user does not exist

• Set visiblepw - this will allow sudo to work, even if the password entered is displayed
  • (required in some cases when echo cannot be disabled).
