About:
CUE is an open-source configuration language that deeply understands and unifies data constraints, templates, and policies. It allows you to define schemas, validate data, and generate configuration for various systems like Kubernetes or Terraform. This tool excels at managing complexity in configuration across different environments.
Key Features:
  • Strongly typed fields with constraints
  • Schema definition and data validation
  • Configuration templating and inheritance
  • Code generation for JSON, YAML, and other formats
Use Cases:
  • Defining and validating Kubernetes manifests
  • Generating Terraform configuration from high-level schemas
  • Managing complex application configuration across environments
Alternatives:
  • JSON Schema – CUE is a full language with templating, while JSON Schema is purely a validation vocabulary.
  • HCL – CUE offers stronger typing and constraint solving, whereas HCL is primarily designed for Terraform's specific needs.
