Kubernetes Deployment Configuration

Configure Kubernetes deployment: $ARGUMENTS

Current Environment Analysis

• Application type: @package.json or @Dockerfile (detect containerization readiness)
• Existing K8s config: !find . -name "*.yaml" -o -name "*.yml" | grep -E "(k8s|kubernetes|deployment|service)" | head -3
• Cluster access: !kubectl cluster-info 2>/dev/null | head -2 || echo "No cluster access"
• Container registry: @docker-compose.yml or check for registry configuration
• Resource requirements: Analysis needed based on application type

Task

Implement production-ready Kubernetes deployment:

1. Kubernetes Architecture Planning

   • Analyze application architecture and deployment requirements
   • Define resource requirements (CPU, memory, storage, network)
   • Plan namespace organization and multi-tenancy strategy
   • Assess high availability and disaster recovery requirements
   • Define scaling strategies and performance requirements

2. Cluster Setup and Configuration

   • Set up Kubernetes cluster (managed or self-hosted)
   • Configure cluster networking and CNI plugin
   • Set up cluster storage classes and persistent volumes
   • Configure cluster security policies and RBAC
   • Set up cluster monitoring and logging infrastructure

3. Application Containerization

   • Ensure application is properly containerized
   • Optimize container images for Kubernetes deployment
   • Configure multi-stage builds and security scanning
   • Set up container registry and image management
   • Configure image pull policies and secrets

4. Kubernetes Manifest Creation

   • Create Deployment manifests with proper resource limits
   • Set up Service manifests for internal and external communication
   • Configure ConfigMaps and Secrets for configuration management
   • Create PersistentVolumeClaims for data storage
   • Set up NetworkPolicies for security and isolation

5. Load Balancing and Ingress

   • Configure Ingress controllers and routing rules
   • Set up SSL/TLS termination and certificate management
   • Configure load balancing strategies and session affinity
   • Set up external DNS and domain management
   • Configure traffic management and canary deployments

6. Auto-scaling Configuration

   • Set up Horizontal Pod Autoscaler (HPA) based on metrics
   • Configure Vertical Pod Autoscaler (VPA) for resource optimization
   • Set up Cluster Autoscaler for node scaling
   • Configure custom metrics and scaling policies
   • Set up resource quotas and limits

7. Health Checks and Monitoring

   • Configure liveness and readiness probes
   • Set up startup probes for slow-starting applications
   • Configure health check endpoints and monitoring
   • Set up application metrics collection
   • Configure alerting and notification systems

8. Security and Compliance

   • Configure Pod Security Standards and policies
   • Set up network segmentation and security policies
   • Configure service accounts and RBAC permissions
   • Set up secret management and rotation
   • Configure security scanning and compliance monitoring

9. CI/CD Integration

   • Set up automated Kubernetes deployment pipelines
   • Configure GitOps workflows with ArgoCD or Flux
   • Set up automated testing in Kubernetes environments
   • Configure blue-green and canary deployment strategies
   • Set up rollback and disaster recovery procedures

10. Operations and Maintenance

    • Set up cluster maintenance and update procedures
    • Configure backup and disaster recovery strategies
    • Set up cost optimization and resource management
    • Create operational runbooks and troubleshooting guides
    • Train team on Kubernetes operations and best practices
    • Set up cluster lifecycle management and governance
