k8s-gen

Kubernetes Manifest Generator

Stop writing YAML by hand. This tool converts your docker-compose files or plain descriptions into production ready Kubernetes manifests. Deployments, Services, ConfigMaps, the whole thing.

One command. Zero config. Just works.

Quick Start

npx ai-k8s "nginx with 3 replicas, exposed on port 80"

What It Does

• Converts docker-compose.yml to Kubernetes manifests automatically
• Generates Deployments, Services, ConfigMaps, and Secrets
• Creates proper resource limits and health checks
• Outputs clean, production ready YAML you can kubectl apply
• Handles multi-service architectures with proper networking

Usage Examples

# Generate from a description
npx ai-k8s "postgres database with persistent volume"

# Convert docker-compose to K8s
npx ai-k8s --compose docker-compose.yml

# Full app stack
npx ai-k8s "node app with redis cache and postgres db, 3 replicas each"

Best Practices

• Start simple - Generate one service first, validate it works, then add complexity
• Review resource limits - The AI sets reasonable defaults, but adjust for your workload
• Use namespaces - Add --namespace flag to keep your deployments organized
• Version your manifests - Commit generated YAML to git, treat it as code

When to Use This

• You know Docker but K8s YAML feels overwhelming
• Migrating docker-compose setups to Kubernetes
• Prototyping new deployments quickly without YAML boilerplate
• Learning K8s concepts through generated examples

Requirements

No install needed. Just run with npx. Node.js 18+ recommended.

npx ai-k8s --help

How It Works

The tool analyzes your docker-compose file or description, understands the services and their relationships, then generates idiomatic Kubernetes manifests. It maps Docker concepts to K8s equivalents like volumes to PersistentVolumeClaims and ports to Services.
