How to run Jenkins jobs on multiple slaves with a single job configuration

Question

I have three different environments each containing a Jenkins Slave,

STAGE1 - slave1
STAGE2 - slave2
STAGE3 - slave3

I don't want to create three different build jobs for them.

I want to pass the slaves (slave1, slave2 and slave3) as parameters, so that if I choose slave1the job gets executed on STAGE1, and if I choose slave2 the job gets executed on STAGE2 and so on.

How to achieve that using a single Jenkins job?

I know there is multi configuration job but I am not clear on how to configure it.

It would be really helpful if I get some information on it.

Answer 1

Below is an approach which you can try.

It can be achieved using

Node and Label Parameter Plugin

It lets you create node and label parameter in the job configuration.

Node parameter contains all the nodes present in your Jenkins including master, you can select the nodes you want.

When you run the job with parameters you can select the desired node and the job will get executed in that particular node.

Answer 2

use multijob plugin

Follow these steps to use the multijob plugin: 

• When creating new Jenkins jobs you will have an option to create MultiJob project.
•  In the build section, this job can define phases that contain one or more jobs.
•  All jobs that belong to one phase will be executed in parallel (if there are enough executors on the node)
•  All jobs in phase 2 will be executed only after the jobs in phase 1 are completed etc.

Hi, 

if i'm understood you would like to choose the slave from external parameters... 

in this case it's pretty simple 

first you should put "label" on your slaves as you mentioned "slave1" "slave2" 

then check the option "This project is parameterized" in the selected job

select string parameter and insert the code bellow in pipeline 

node (params.slave) {
    stage('test'){
        sh 'terraform --version'
    }
}

done :)

Use mulijob in the following way:

• When creating new Jenkins jobs you will have an option to create MultiJob project.
•  In the build section, this job can define phases that contain one or more jobs.
•  All jobs that belong to one phase will be executed in parallel (if there are enough executors on the node)
•  All jobs in phase 2 will be executed only after the jobs in phase 1 are completed etc.
