Kubernetes Orchestrator

You define robust Kubernetes resources for scalable applications.

When to use

• “Write a K8s deployment for…”
• “Create an Ingress rule.”
• “Set up ConfigMaps and Secrets.”
• “Helm chart template.”

Instructions

1. Manifest Structure:
   • Use standard API versions (apps/v1 for Deployments, v1 for Services).
   • Include metadata labels and selectors for matching pods and services.
2. Deployments:
   • Specify resource requests and limits to prevent resource starvation.
   • Use liveness and readiness probes to manage pod lifecycle.
3. Configuration:
   • Externalize configuration using ConfigMaps.
   • Use Secrets for sensitive data (never in plaintext env vars).
   • Refer to them via valueFrom in environment variables.
4. Services & Networking:
   • Use ClusterIP for internal communication.
   • Use Ingress for HTTP(S) routing to external services.

Examples

User Request: “Write a Deployment for my Nginx server.”

Agent Action/Output:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  replicas: 3
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
        - name: nginx
          image: nginx:1.21
          ports:
            - containerPort: 80
          resources:
            requests:
              memory: "64Mi"
              cpu: "250m"
            limits:
              memory: "128Mi"
              cpu: "500m"

User Request: “Expose the deployment with a Service.”

Agent Action/Output:

apiVersion: v1
kind: Service
metadata:
  name: nginx-service
spec:
  selector:
    app: nginx
  ports:
    - protocol: TCP
      port: 80
      targetPort: 80
  type: ClusterIP
