Not able to run ansible-playbook using becomeUser - jenkins

Question

I'm trying to run ansible-playbook from Jenkinsfile with become and becomeUser parameters but it seems Jenkins is taking its own userid "jenkins" to connect to remote host
Jenkinsfile
stage("Deployment"){
steps{
ansiColor('xterm') {
ansiblePlaybook(
playbook: 'myPlaybook.yaml',
inventory: 'myHosts.ini',
colorized: true,
become: true,
becomeUser: 'userID',
extras: '-vvv'
)
}
}
}
I also appended become and becomeUser in playbook as well
---
- name: Deploy stack from a compose file
hosts: myNodes
become: yes
become_user: userID
tasks:
- name: deploying my application
docker_stack:
state: present
Jenkins build log

fatal: [x.x.x.x]: UNREACHABLE! => {
"changed": false,
"msg": "Failed to connect to the host via ssh: jenkins#x.x.x.x: Permission denied (publickey,password).",
"unreachable": true
}
Even jenkins run with become and becomeUser command
[xx-yy] $ ansible-playbook myplaybook.yaml -i myHosts.ini -b --become-user userID -vvv
Please advise to resolve this, Thanks.

Answer 1

Found the alternate solution. Observed the logs line by line:
ESTABLISH SSH CONNECTION FOR USER: None
<x.x.x.x> ESTABLISH SSH CONNECTION FOR USER: None
<x.x.x.x> SSH: EXEC ssh -C -o ControlMaster=auto -o ControlPersist=60s -o 'IdentityFile="/var/lib/jenkins/.ssh/id_rsa"' -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey -o PasswordAuthentication=no -o ConnectTimeout=10 -o ControlPath=/var/lib/jenkins/.ansible/cp/5493f46899 x.x.x.x '/bin/sh -c '"'"'echo ~ && sleep 0'"'"''
<x.x.x.x> (255, '', 'jenkins#x.x.x.x: Permission denied (publickey,password).\r\n')
Hence added ansible_user while doing ssh to remote user in inventory file:
[myNode]
x.x.x.x ansible_user=myuserId

The below link could be helpful for you in understanding about become and become_user.
Medium Blog Link here .
And this is the snippet worth sharing,
# as bruce
$ ansible all -m ping -u bruce
# as bruce, sudoing to root
$ ansible all -m ping -u bruce --sudo
# as bruce, sudoing to batman
$ ansible all -m ping -u bruce --sudo --sudo-user batman
# With latest version of ansible `sudo` is deprecated so use become
# as bruce, sudoing to root
$ ansible all -m ping -u bruce -b
# as bruce, sudoing to batman
$ ansible all -m ping -u bruce -b --become-user batman
