Policy as Code - Past, Present and Future for Novice

Learn about Policy as Code (PaC) in Kubernetes through this 26-minute conference talk that traces its evolution from past implementations to future possibilities. Explore how Kubernetes admission control mechanisms have transformed from webhook-based systems to the integration of Common Expression Language (CEL) starting in version 1.23. Discover the progression of Validating Admission Policy, which reached General Availability in v1.30, and examine Mutating Admission Policy currently in Alpha in v1.32. Understand how Policy as Code enhances Kubernetes security by leveraging the platform's declarative YAML nature to reduce human error and improve usability. Gain insights into practical demonstrations of admission control functionality and learn how security policies can be implemented directly within Kubernetes as code, making the concept accessible for those new to Kubernetes while providing valuable context for the future direction of policy management in cloud native environments.
