2. SUCCESSFULLY IMPLEMENTED AT
3. I WILL SHOW YOU ‣Parent-child pipeline ‣Dynamic child pipeline ‣Use cases ‣Live demo
4. WHAT IS PARENT-CHILD PIPELINE?
5. WHAT IS PARENT-CHILD PIPELINE? Similarly to multi-project pipelines, a pipeline can trigger a set of concurrently running child pipelines, but within the same project
9. WHY PARENT-CHILD PIPELINE?
11. WHY PARENT-CHILD PIPELINE? ‣Too big .gitlab-ci.yml fi le ‣Ineffective blocking stages ‣Imports complexity + collisions ‣Pipeline UX
12. WHAT IS DYNAMIC-CHILD PIPELINE? Instead of running a child pipeline from a static YAML fi le, you can de fi ne a job that runs your own script to generate a YAML fi le, which is then used to trigger a child pipeline.
14. WHY DYNAMIC-CHILD PIPELINE?
15. USE CASE(S): MONOREPO
