Execute a remote command after sudo - su anotheruser in Rundeck

sudo rundeck

I'm new with Rundeck and completely amazed with it and I'm trying to execute a job and my scenario is detailed bellow:

  • Rundeck is configured with ssh password less authentication between node Server (rundeck server) and node Target (remote Solaris host) for user "master".

  • In node Target I want to execute a script /app/acme/stopApp.sh with user appmanager.

  • Normally when I need to run the script above I manually proceed with:

ssh master@server

sudo su - appmanager

or simply 

ssh -t master@server
sudo su - appmanager

works without password and finally run (as appmanager)

/app/acme/stopApp.sh

But I don't know how can I reproduce these steps using Rundeck. I read in some previous messages that for each job line rundeck uses a new ssh connection, so the workflow bellow always fails for me with the messages:

sudo: no tty present and no askpass program specified Remote command failed with exit status 1

Could someone please help me with this issue?

Without this functionality I wouldn't be able to introduce a little DevOps in my department. :-D

I read the user guide and admin guide but I couldn't find an easy example, neither in this forum, to follow.

I will appreciate your help.

Rundeck version is 1.4

sudo su - appmanager

Tries to open a login shell, and therefore wants a real terminal. Remove the "-" to avoid this behavior. In the end, your command is going to look like

sudo su -c /app/acme/stopApp.sh appmanager
