CEL Policies

This hands-on lab teaches you how to use CEL (Common Expression Language) in Kyverno policies for modern validation approaches.

You'll learn to:

• Understand CEL syntax and expressions
• Create validation policies using CEL instead of patterns
• Use CEL variables and functions for complex logic
• Leverage CEL's type-safe expressions for reliable policies
• Migrate existing pattern-based policies to CEL

CEL provides a more expressive and performant way to write validation logic in Kyverno policies.
