k8s-generator

Kubernetes Generator

Generate complete Kubernetes manifests by analyzing your application. Creates Deployments, Services, ConfigMaps, Secrets, Ingress, and HPA with production best practices.

What This Skill Does

• Auto-generates K8s manifests from project analysis
• Creates proper resource limits and requests
• Implements health checks (liveness/readiness probes)
• Generates ConfigMaps and Secrets management
• Includes Horizontal Pod Autoscaler (HPA)
• Follows 12-factor app principles

Instructions

Phase 1: Application Analysis

Analyze the application to determine requirements:

# Detect application type
Use Glob/Grep to find:
- Dockerfile → Container config
- .env → Environment variables
- Port bindings
- Volume requirements

Phase 2: Generate Core Manifests

Deployment:

apiVersion: apps/v1
kind: Deployment

          limits:
            memory: "256Mi"
            cpu: "200m"
        livenessProbe:
          httpGet:
            path: /health
            port: 3000
          initialDelaySeconds: 30
          periodSeconds: 10
        readinessProbe:
          httpGet:
            path: /ready
            port: 3000
          initialDelaySeconds: 5
          periodSeconds: 5
        envFrom:
        - configMapRef:
            name: myapp-config
        - secretRef:
            name: myapp-secrets

Service:

apiVersion: v1
kind: Service
metadata:

spec:
  selector:
    app: myapp
  ports:
  - protocol: TCP
    port: 80
    targetPort: 3000
  type: ClusterIP

ConfigMap:

apiVersion: v1
kind: ConfigMap
