DRY development: A cheatsheet on reusability throughout GitLab

Over two decades ago, "The Pragmatic Programmer" introduced the DRY principle, emphasizing the importance of minimizing duplication in systems by ensuring each piece of knowledge has a single representation. In modern development environments, especially within DevOps, balancing new feature development with maintaining existing code is crucial, and reducing duplicate knowledge across projects is an ongoing challenge. This tutorial highlights mechanisms in GitLab that utilize the DRY principle to reduce code duplication and standardize knowledge, such as using YAML anchors, extending blocks of CI workflows, and leveraging downstream pipelines to break out microservices. These techniques improve readability and ownership of code by transforming a single .gitlab-ci.yml file into multiple files. Additional GitLab features like CI/CD variables, description templates for consistent code reviews, and project templates for initializing new projects further support best practices. Emphasizing the creation of a "Pipeline Center of Excellence" project can help organizations adopt consistent CI/CD workflows by utilizing well-defined templates and abstracted constructs, ensuring development teams can easily adopt best practices without reinventing the wheel.
