When & Why to Use This Skill

The Kubernetes Helper skill streamlines the deployment and management of cloud-native applications by automating the generation of production-ready Kubernetes manifests and Helm charts. It ensures infrastructure consistency and reliability by integrating industry best practices, such as resource limits, health checks, and secure secret management, directly into the generated YAML configurations.

Use Cases

  • Rapidly generating boilerplate YAML manifests for Deployments, Services, and Ingress to accelerate new microservice onboarding.
  • Implementing Kubernetes best practices by automatically adding liveness probes, readiness probes, and resource constraints to container configurations.
  • Simplifying complex environment management by converting static manifests into reusable and scalable Helm charts.
  • Providing a quick-reference toolkit of essential kubectl commands for troubleshooting, scaling, and monitoring cluster resources in real-time.

            cpu: "200m"
        livenessProbe:
          httpGet:
            path: /health
            port: 8080
          initialDelaySeconds: 30
          periodSeconds: 10
        readinessProbe:
          httpGet:
            path: /ready
            port: 8080
          initialDelaySeconds: 5
          periodSeconds: 5

Service

apiVersion: v1

    server {
      listen 80;
      server_name example.com;
    }
  database.yml: |
    production:
      adapter: postgresql
      database: myapp

Secret

apiVersion: v1
kind: Secret
metadata:

type: Opaque
stringData:
  database-url: postgresql://user:pass@host:5432/db
  api-key: sk_live_abc123

Ingress

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: myapp-ingress
  annotations:
    cert-manager.io/cluster-issuer: letsencrypt
spec:
  tls:
  - hosts:
    - example.com
    secretName: myapp-tls
  rules:
  - host: example.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: myapp-service
            port:
              number: 80

よく使うコマンド

# Podの確認
kubectl get pods

# ログ確認
kubectl logs <pod-name>

# Podに入る
