2 posts · Aug 2018 – Apr 2019

What this trail covers

Shopify has evolved its approach to managing and debugging Kubernetes Ingress controllers, specifically ingress-nginx. This post details the development and contribution of a kubectl plugin that simplifies upgrades by identifying breaking changes, provides a more detailed listing of ingress configurations, and streamlines common debugging tasks by automating pod selection and providing convenient wrappers for kubectl commands. This has significantly reduced the time and effort required for upgrades and debugging.

All Shopify trails
  1. A New Kubectl Plugin for Kubernetes Ingress Controller ingress-nginx - ShopifyContributed a kubectl plugin to the ingress-nginx project that simplifies upgrades by identifying breaking changes, provides a more detailed listing of ingress configurations, and streamlines common debugging tasks by automating pod selection and providing convenient wrappers for kubectl commands.
  2. Iterating Towards a More Scalable Ingress - ShopifyContributed dynamic configuration to ingress-nginx, enabling in-memory endpoint updates via a Lua-based HTTP endpoint. This eliminates NGINX reloads during deployments, reducing latency and improving performance, particularly during application updates.
