Article 05: Mastering GDK: How to Shave 50% Off Your Local GitLab Development & Test Cycles

• Target Publication: DEV.to
• Strategic Category: Open Source Contributor Tooling
• The Hook: The GitLab Development Kit (GDK) is a beast with dozens of microservices. How do maintainers and top contributors run it fast on modern developer laptops without turning their machine into a heater?
• Key Concepts Covered:
  • Slimming GDK: disabling unused services (Elasticsearch, OpenBao, ClickHouse, AI Gateway) when working on core Rails.
  • Speeding up assets: tuning Vite hot-module reloading and skipping pre-compilations.
  • Running fast unit tests: using Spring, local RSpec filtering, and bypassing monolithic seed data.
  • Avoiding common RuboCop and Danger errors locally before pushing.
• Why It Gets Approved (200 Pts): Invaluable for the GitLab Contributor community, lowering the barrier to entry for prospective contributors.

Article 06: Zero-Downtime Database Migrations: Inside GitLab's Batched Background Migrations (BBM)
