Kubernetes Deployment Manifest Generator

Generate a complete set of Kubernetes manifests for deploying an application to production with the following specifications:

Application Details

• Application Name: [e.g., myapp, api-server, web-frontend]
• Namespace: [production / staging / default]
• Container Image: [e.g., myorg/myapp:1.0.0]
• Container Port: [e.g., 3000, 8080]
• Replicas: [Initial number, e.g., 3]

Resource Requirements

• Memory Request: [e.g., 256Mi]
• Memory Limit: [e.g., 512Mi]
• CPU Request: [e.g., 100m]
• CPU Limit: [e.g., 500m]

Environment Variables

List all environment variables needed:

• [VAR_NAME_1]: [value / from-secret / from-configmap]
• [VAR_NAME_2]: [value / from-secret / from-configmap]
• [VAR_NAME_3]: [value / from-secret / from-configmap]

Health Checks

• Liveness Probe: [HTTP path, e.g., /health]
• Readiness Probe: [HTTP path, e.g., /ready]
• Initial Delay: [seconds, e.g., 30]
• Period: [seconds, e.g., 10]

Service Configuration

• Service Type: [ClusterIP / LoadBalancer / NodePort]
• Service Port: [External port, e.g., 80]
• Target Port: [Container port, e.g., 3000]

Ingress Configuration

• Domain: [e.g., myapp.example.com]
• Path: [e.g., /, /api]
• TLS/SSL: [Yes / No]
• Certificate Issuer: [e.g., letsencrypt-prod]
• Ingress Class: [e.g., nginx]
• Additional Annotations: [List any custom annotations]

ConfigMap Data

List configuration files/data to include:

• [config-file-1.conf]: [Description of what it contains]
• [config-file-2.json]: [Description of what it contains]

Secrets

List secrets needed (DO NOT include actual values):

• [secret-key-1]: [Description, e.g., database connection string]
• [secret-key-2]: [Description, e.g., API key]
• [secret-key-3]: [Description, e.g., JWT secret]

Autoscaling (HPA)

• Min Replicas: [e.g., 3]
• Max Replicas: [e.g., 10]
• CPU Target: [Utilization %, e.g., 70]
• Memory Target: [Utilization %, e.g., 80]

Additional Requirements

• Include proper labels and selectors
• Add resource requests and limits
• Configure liveness and readiness probes
• Set up horizontal pod autoscaling
• Include security context if needed
• Add annotations for monitoring/logging

Deliverables

Generate the following Kubernetes manifest files:

1. deployment.yaml - Deployment with container specs, env vars, probes, resources
2. service.yaml - Service exposing the application
3. ingress.yaml - Ingress with TLS and routing rules
4. configmap.yaml - ConfigMap with configuration data
5. secret.yaml - Secret template (with placeholder values)
6. hpa.yaml - HorizontalPodAutoscaler for autoscaling

All manifests should be production-ready and follow Kubernetes best practices. Include comments explaining key configurations.
