Setting up Jenkins job in Rundeck 3.4.9 community version - jenkins

Question

I want to setup a Jenkins job which should be triggered by Rundeck. I have already installed Rundeck plugin and tested the connection between Rundeck and Jenkins which is working as expected.
Now, my requirement is that the same Jenkins job should be triggered by Rundeck. I am using Rundeck 3.4.9 community version.
How can I setup a Jenkins job in Rundeck and what configurations I need to do on both Rundeck and Jenkins end?

Answer 1

You can design a Rundeck job that call the Jenkins job using this endpoint via CURL.
I tested successfully with this endpoint:
http://user:JENKINS_USER_TOKEN#localhost:8080/job/TestJob/build
You can use the http workflow step to send post requests using that URL format.

Here is a job definition example:
- defaultTab: nodes
description: ''
executionEnabled: true
id: 1fa2923a-5b1d-4ea2-97d1-4cc2a3726f07
loglevel: INFO
name: ExampleJENKINS
nodeFilterEditable: false
plugins:
ExecutionLifecycle: null
scheduleEnabled: true
sequence:
commands:
- exec: echo "starting..."
- fileExtension: .sh
interpreterArgsQuoted: false
script: curl -vvv -X POST http://admin:11bd72f1f22653cf7158c7961f60476a1d#localhost:8080/job/MyJenkinsJob/build
scriptInterpreter: /bin/bash
keepgoing: false
strategy: node-first

Another way is to use the HTTP Step plugin with a basic authentication configured.
