Go Kure

Kure: Type-Safe Kubernetes Resource Generation

Kure is a powerful Go library for programmatically building Kubernetes resources, designed specifically for GitOps workflows. Say goodbye to complex templating engines and hello to strongly-typed, composable resource generation.

Why Kure?

Building Kubernetes manifests for GitOps can be challenging:

• YAML templating is error-prone and hard to maintain
• Helm charts add complexity with their templating language
• Raw manifests lead to duplication and inconsistency

Kure solves these problems by providing:

• Type-safe builders that catch errors at compile time
• Composable patterns for reusable resource generation
• Native Go code instead of template syntax
• GitOps-ready output for Flux and ArgoCD

Features

• Comprehensive Resource Support

  • Core Kubernetes resources (Deployments, Services, ConfigMaps, etc.)
  • FluxCD resources (Kustomizations, HelmReleases, Sources)
  • cert-manager integration
  • External Secrets Operator
  • MetalLB configuration

• Hierarchical Organization

  • Cluster → Node → Bundle → Application structure
  • Logical grouping of related resources
  • Clean directory layout generation

• Advanced Capabilities

  • JSONPath-based patching system
  • Multi-environment support
  • OCI registry integration
  • Validation and error handling

Quick Start

import "github.com/go-kure/kure/pkg/fluxcd"

// Create a Flux Kustomization
ks := fluxcd.CreateKustomization("my-app", "default", 
    kustv1.KustomizationSpec{
        Path: "./manifests",
        SourceRef: kustv1.CrossNamespaceSourceReference{
            Kind: "GitRepository",
            Name: "my-repo",
        },
    })
