This feature thread tracks the development and enhancement of tools and strategies for managing and debugging Kubernetes Ingress controllers, specifically ingress-nginx. Initial efforts focused on improving the quality of the debugging experience for ingress-nginx, which is critical for Shopify's infrastructure. This post introduces a new kubectl plugin that simplifies upgrades by identifying breaking changes, provides a more detailed listing of ingress configurations, and streamlines common debugging tasks. It also details the contribution of dynamic configuration to ingress-nginx, allowing for in-memory endpoint updates and eliminating the need for NGINX reloads during application deployments, significantly improving request latencies, especially during deploys.
