Before telling me about /etc/sudoers file here it is:
#
# 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.
#
Defaults env_reset
Defaults mail_badpass
Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"
# Host alias specification
# User alias specification
# Cmnd alias specification
# User privilege specification
root ALL=(ALL:ALL) ALL
jenkins ALL=(ALL) NOPASSWD: ALL
# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL
# Allow members of group sudo to execute any command
%sudo ALL=(ALL:ALL) ALL
# See sudoers(5) for more information on "#include" directives:
#includedir /etc/sudoers.d
In the beginning I was trying to run a sudo command remotely. I edited the sudoers file with visudo to let jenkins user the ability to run sudo commands with no password asked.
once i realized that I have another problem I even tried to run (when I logged on as jenkins user) the following : ssh localhost "sudo w" even that doesn't work.
getting this error : sudo: no tty present and no askpass program specified
any ideas?
thanks!
EDIT:
I'm trying to run bash sudo commands from jenkins master machine on slave machine in post step job (done it alredy with other slave).
When I run the job it failed with error : sudo: no tty present and no askpass program specified. from my debugging, it seems that the problem not relating to the master, because I tried to send sudo command over ssh within the slave machine and got the same error.
My expectation is to make it work. the way it already worked on a different salve machine. (which i also test the same logic within the other salve machine by sending sudo command over ssh pointing localhost --- worked just fine
it seems like there is no tty for sudo command over ssh... I'm not an expert of TTY or SSH. Maybe I'm missing something...
SOLVED! I think it is a BUG...
I moved the this line to the end of the /etc/sudoers and it works!
jenkins ALL=(ALL) NOPASSWD: ALL
so the file looks like this:
#
# 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.

ssh
? That's not a bug, if so.
