I love to solve complex CI/CD problems and challenges.

I offer consultations on various topics. If you would like to get a helping hand, let's have chat, maybe I can help you.

Goal is to demonstrate through the demos, how to get from "classic approach" to parent-child pipelines, with dynamic child pipelines.

As a bonus, there is simple script, that can build up "dependency tree" for packages. It is used to trigger pipelines only for those packages that are affected and their dependencies.

"Classic approach" - monorepo without parent-child pipelines, everything run in the same pipeline.

• Code
• Pipeline

Simple implementation of parent-child pipelines.

• Code diff
• Pipeline

Example of failed pipeline to demonstrate the UI and behaviour.

• Code diff
• Pipeline

Introduction of depend strategy to make parent pipeline fail if one of children fail.

• Code diff
• Pipeline

Introduction to dynamic child pipelines with exactly the same behaviour - dynamically generating pipelines for all packages. This is 2 level parent-child pipelines.

• Code diff
• Pipeline

Introduction to merge request pipelines (without dynamic child pipelines yet) - trigger pipeline only package that has been directly changed.

• Code diff
• Pipeline

Merge request pipelines with dynamic child pipelines combined together.

• Code diff
• Pipeline

The "Ultimate demo" - merge request pipeline with dynamic child, run pipelines for package that has been directly changed + all dependent packages, to make sure nothing have been broken up.

• Code diff
• Pipeline - package A changed (has no dependencies on it)
• Pipeline - Package C changed (pkg A depends on C)
