CI Config Refactor Kit

How It Works

CI configs grow into "configuration codebases." This recipe adds structure: modules,

naming conventions, and validation checks to make changes safer.

Triggers

• CI config is large and hard to reason about
• People are afraid to touch pipeline YAML
• Small CI changes cause surprising side effects

Steps

1. Inventory jobs and group by intent: build, test, deploy, security, release.
2. Extract repeated logic into scripts (versioned) or reusable CI templates.
3. Add comments documenting *why* each job exists and what it gates.
4. Add a CI "lint" stage for the pipeline config itself.
5. Introduce change control for CI files (ownership + required reviewers).

Expected Outcome

• CI becomes readable and maintainable.
• Pipeline changes become auditable and less risky.

Example Inputs

• "Our gitlab-ci.yml is 600 lines and growing."
• "Developers accidentally trigger expensive pipelines."
• "We need a consistent pattern for includes/extends."

Tips

• Prefer clarity over cleverness; CI is a shared operational surface.
