Скачать или смотреть CRD Validation in Kubernetes - Chirag Kyal, Red Hat - KCD Hyderabad 2024

In his talk, Chirag talked about how CRDs are the backbone of Kubernetes extensibility, but let's be honest, wrestling with validation can be a real head-scratcher, right? The reliance on admission webhooks can feel like a maze. Have you ever wondered if there's a better way? Join this session where I'll delve into the issues and complexities tied to webhooks, from managing binary bundles to dealing with multi-version CRDs, it's clear that there's room for improvement.

Common Expression Language (CEL) has emerged as a potential addition to Kubernetes (Beta in 1.25, GA in 1.29), and it might just be the answer to our webhook woes. In this talk, I’ll introduce CEL and how it can be integrated into Kubernetes to simplify CRD validation. With a concise live demonstration, I’ll explore CEL’s potential for advanced validation rules including multi-field validations, immutability checks, and more - all thoughtfully integrated directly within your CRD definitions, allowing you to a safe cluster operations and better development experience.
