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:

• 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

• 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

• 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

• 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
