How to trigger a Jenkins pipeline A in another Jenkins pipeline B

Question

I’ve created two Jenkins pipeline, let’s say pipelineA and pipelineB. I want to invoke pipelineA in pipelineB. How can this be done?

Answer 1

You can run the following code, its an example of running pipelineA in pipeline.

Make sure you’ve created a ‘pipelineA’ before running this code.

pipeline {
agent
    {
        node {
                label 'master'
                customWorkspace "${env.JobPath}"
              }
    }
    stages 
    {
        stage('Start') {
            steps {
                echo 'Hello'
            }
        }
        stage ('Invoke_pipelineA') {
            steps {
                build job: 'pipelineA', parameters: [
                string(name: 'param1', value: "value1")
                ]
            }
        }
        stage('End') {
            steps {
                echo 'Bye'
            }
        }
    }
}

Comments

I think the question was to trigger a pipeline from another jenkins.

I think what @Tyrion meant is that he has two pipelines on same Jenkins and would like to invoke pipeline in pipelineB

---

Can we call the downstream job in other Jenkins environments ?

You can definitely use the downstream approach. But the thing with downstream is that you can invoke PipelineB only after PipelineA is executed.

What if I want to execute PipelineB somewhere in between the execution of PipelineA?

Answer 2

If you are talking about executing another pipeline job, the "build job" step can accomplish this:

build job: '<Project name>', propagate: true, wait: true

propagate: Propagate errors

wait: Wait for completion

If you have paramters on the job, you can add them like this:

build job: '<Project name>', parameters: [[$class: 'StringParameterValue', name: 'param1', value: 'test_param']]

Hi,

You can follow the below steps to trigger a Jenkins pipeline in another Jenkins pipeline.

Select a job that triggers a remote one and then go to Job Configuration > Build section > Add Build Step > Trigger builds on remote/local projects option. This configuration allows you to trigger another exciting job on a different CM (remote). The downstream job name part will autocomplete.
