This is an example of child pipeline generation on Gitlab

main.py

import os
from PipelineWriter import PipelineWriter


def get_libs():
    libs_path = "lib/java"
    libs = os.listdir(libs_path)
    return libs

def generator():
    with open('child-pipeline-gitlab-ci.yml', 'w+') as f:
        f.write(PipelineWriter.parent_jobs_template())
        for lib in get_libs():
            f.write(PipelineWriter.child_pipeline_job_template(lib))

if __name__ == "__main__":
    generator()
