5 ways GitLab pipeline logic solves engineering problems

This post introduces five advanced CI/CD pipeline patterns in GitLab: parent-child pipelines and DAG execution for monorepos, multi-project pipelines for microservices, and dynamic child pipelines for multi-tenant/matrix deployments. It details configuration examples for each pattern, emphasizing how they solve engineering problems related to pipeline runtime, cross-repo visibility, and configuration drift. It also touches on merge request pipelines, merged results pipelines, and workflow rules for MR-first delivery.
