KCL is an open-source configuration and policy language hosted by the Cloud Native Computing Foundation (CNCF) as a Sandbox Project. Built on a foundation of constraints and functional programming principles, KCL enhances the process of writing complex configurations, particularly in cloud-native environments. By leveraging advanced programming language techniques, KCL promotes improved modularity, scalability, and stability in configuration management. It simplifies logic writing, offers easy-to-use automation APIs, and seamlessly integrates with existing systems.
