CI/CD Anti-Patterns and Migration Strategies#

CI/CD pipelines accumulate technical debt faster than application code. Nobody refactors a Jenkinsfile. Nobody reviews pipeline YAML with the same rigor as production code. Over time, pipelines become slow, fragile, inconsistent, and actively hostile to developer productivity. Recognizing the anti-patterns is the first step. Migrating to better tooling is often the second.

Anti-Pattern: Snowflake Pipelines#

Every repository has a unique pipeline that someone wrote three years ago and nobody fully understands. Repository A uses Makefile targets, B uses bash scripts, C calls Python, and D has inline shell commands across 40 pipeline steps. There is no shared structure, no reusable components, and no way to make organization-wide changes.
