I want to use a python script as input to create stages in jenkins pipeline


{'job-name': 'Test1', 'action': 'a', 'targetname': 'x'}
{'job-name': 'Test2', 'action': 'b', 'targetname': 'y'} 
{'job-name': 'Test3', 'action': 'c', 'targetname': 'z'}

The output of the above python script is a dictionary.

How to run this python script in Jenkins pipeline in a stage and how to store the output and use the output to define further stages


stage(Test1) {

stage(Test2) {

stage(Test3) {


Extract only 'value' of a particular 'key' from the output of python script to define stages in Jenkins pipeline.

How to execute it in Jenkins groovy as declarative pipeline ?

This was already asked and answered over on StackOverflow.

TL;DR: you must use Scripted Pipeline; Declarative does not support dynamic stages. Here is a copy-paste of the top answer:

Use the scripted syntax that allows more flexibility than the declarative syntax, even though the declarative is more documented and recommended.

For example stages can be created in a loop:

def tests = params.Tests.split(',')
for (int i = 0; i < tests.length; i++) {
    stage("Test ${tests[i]}") {
        sh '....'
  • is this file complete or would you need to wrap this in a stages block? Commented Oct 27, 2022 at 20:23
  • It would need to be wrapped in a script { } block.
