Continuous Integration Tips & Tricks
summary
A set of concrete CI changes that actually speed feedback: a claimed reduction from 1h20 to 13 minutes by tuning infrastructure and pipeline shape; flip Jenkins to Performance optimized, use spot instances and set one executor per worker; shallow clone and disable tags to cut checkout time; leave workspaces for post‑fail inspection; linting and tiny bash unit checks; parallel Docker builds, pre‑pull images, Docker BuildKit secrets/SSH, and isolate parallel tests with docker‑compose -p; VNC for live UI debug and an eye toward Dagger for future builds.
