"Acing" Infrastructure Testing with Chef
summary
Team moves local testing to the IBM cloud using the kitchen OpenStack plugin and a gem that converts kitchen configs to cloud-friendly ones, cutting pre-converge idle time from ~7.5 minutes to under 30 seconds. Optimizations include reducing boot from ~59s to ~8s (grub, DHCP, systemd tuning), switching file transfer to tar-over-ssh and kitchen-sink (prepare down to ~3.4s), packaging binaries with fpm cookery, and running yum makecache via cloud-init in the background.
