• flux2

  96 6,599 8.9 Go

  Open and extensible continuous delivery solution for Kubernetes. Powered by GitOps Toolkit.

  

  FluxCD - FluxCD is another popular GitOps tool that allows developers to use a Git repository as the sole source of configuration. Flux automatically ensures that the state of the Kubernetes cluster is synchronized with the configuration in the Git repository. It supports automatic updates, meaning Flux can monitor Docker image repositories for new images and push updates to the cluster.

• cdk8s

  49 4,388 9.7 JavaScript

  Define Kubernetes native apps and abstractions using object-oriented programming

  

  CDK8s - CDK8s is used to define Kubernetes resources and applications. CDK8s uses the high-level abstraction concept called constructs to represent various Kubernetes resources such as deployments, services, and configurations. Developers can write code in programming languages like TypeScript, Python, and Java, and CDK8s will translate this code into standard Kubernetes YAML manifests that can be directly applied to a Kubernetes cluster.

• gcl

  1 58 10.0 Python

  Generic Configuration Language (A reusable configuration language for Python) (by rix0rrr)

  GCL: A declarative configuration programming language implemented in Python provides the necessary language capabilities to support template abstraction. However, the compiler itself is written in Python, and the language itself is interpreted and executed. For large template instances (such as Kubernetes models), the performance is poor.

• hcl

  43 5,308 7.7 Go

  HCL is the HashiCorp configuration language.

  

  HCL: A Go implementation structured configuration language. The native syntax of HCL is inspired by libucl and nginx configurations. It is used to create a structured configuration language that is friendly to humans and machines, mainly for DevOps tools, server configurations, and resource configurations as a Terraform language.

• jsonnet

  49 7,017 7.7 Jsonnet

  Jsonnet - The data templating language

  

  Jsonnet: A data template language implemented in C++, suitable for application and tool developers, can generate configuration data and organize, simplify and manage large configurations without side effects.

• OPA (Open Policy Agent)

  97 9,748 9.7 Go

  Open Policy Agent (OPA) is an open source, general-purpose policy engine.

  

  OPA: While OPA is an open-source, general-purpose policy engine capable of enforcing unified and context-aware policies throughout the stack, it can also accept and output data in formats such as JSON, effectively functioning as a tool for generating or modifying configurations. Although it does not provide out-of-the-box schema definition support, it allows the integration of JsonSchema definitions.

• starlark

  25 2,502 3.8 Starlark

  Starlark Language

  

  Starlark: Starlark is a language for describing build transformations, inspired by Python, but with features that make it suitable for embedding in software like Bazel. It can be used for configuration generation due to its capability for deterministic evaluation and expressing complex build transformations.

• cue

  117 5,158 9.9 Go

  The home of the CUE language! Validate and define text-based and dynamic configuration

  

  CUE: The core problem CUE solves is "type checking", which is mainly used in configuration constraint verification scenarios and simple cloud native configuration scenarios.

• dhall-lang

  118 4,232 5.0 Dhall

  Maintainable configuration files

  

  Dhall: Dhall is a programmable configuration language that combines features like JSON, functions, types, and import capabilities. Its style leans towards functional programming, so if you're familiar with functional-style languages such as Haskell, you might find Dhall to be quite intuitive.

• kcl

  42 1,717 9.7 Rust

  KCL Programming Language (CNCF Sandbox Project). https://kcl-lang.io

  

  KCL: A declarative configuration and policy programming language implemented by Rust, which improves the writing of a large number of complex configurations through mature programming language technology and practice, and is committed to building better modularity, scalability and stability around configuration, simpler logic writing, fast automation and good ecological extensionally.
