k8s-gen – OpenClaw Skill

---

name: k8s-gen description: Generate Kubernetes manifests from docker-compose or plain English. Use when deploying apps to K8s.

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.

ai-k8s

Got a docker-compose file and need to move to Kubernetes? Don't spend hours translating YAML by hand. Just feed it in and get proper K8s manifests back.

Install

npm install -g ai-k8s

Usage

# From a docker-compose file
npx ai-k8s docker-compose.yml --namespace production

# From a description
npx ai-k8s "3 replicas of a node app with redis and postgres"

# Save output
npx ai-k8s docker-compose.yml -o k8s-manifests.yml

Setup

export OPENAI_API_KEY=your-key-here

Options

• -n, --namespace <ns> - Target namespace (defaults to "default")
• -o, --output <file> - Write to a file
