Unable to switch to a sudo user using ssh pipeline

Issue Type:	Task
Assignee:	Naresh Rayapati
Components:	ssh-steps-plugin
Created:	2019-03-26 23:58
Environment:	Production
Priority:	Major
Reporter:	Anurag GADDAMANUGU

My task is to perform certain operations on Linux server as a sudo user.

Current Situation: Using the ssh pipeline plugin I am able to login into the remote server and run the command using sshCommand.

Issue: To perform other operations I need to switch to a sudo user with a password. I am unable to find if this is possible with this plugin.

Please refer to the below code and let us know you suggestions to the issue

def remote = [:]
remote.name = '<server name>'
remote.host = '<server host name>'
remote.user = '<userId>'
remote.password = '<password>'
remote.allowAnyHosts = true
remote.agent = true
node{
stage('Remote SSH')

{ sshCommand remote: remote, command: "ls lrt" Able to Execute the pipeline until here sshCommand remote: remote, command: "sudo su <sudo Username>",sudo: true — Not sure if this is the right usage }

}

Re: Unable to switch to a sudo user using ssh pipeline

Given the password for the user configured for remote is same as the sudo Username, the example in the description works, which is very rare.

Why don't do try configuring the actual sudo user and password for the remote to execute these sudo commands?

def remote = [:]
 remote.name = '<server name>'
 remote.host = '<server host name>'
 remote.user = '<userId>'
 remote.password = '<password>'
 remote.allowAnyHosts = true
 remote.agent = true
 node {
  stage('Remote SSH'

) {
     sshCommand remote: remote, command: "ls lrt"   // This works.
     sshCommand remote: remote, command: "sudo ls -lrt", sudo: true // This should work too given userId as sudo access and configured as non passwordless sudo access (requires password for sudo commands)
   }
 }

Re: Unable to switch to a sudo user using ssh pipeline

Hello Naresh,

I am currently using SSH-steps plugin to run few commands. I am able to run most commands that do not require sudo, however when I run commands that require sudo, the pipeline hangs. I get error "org.hidetake.groovy.ssh.session.BadExitStatusException: Command returned exit status 1: sudo -S ......" The account i am connecting do not have passwordless sudo access. Do we need to have passwordless access?

Thanks,
Tharun
