# Creating Kubernetes Deployments

> Deploy use when generating Kubernetes deployment manifests and services. Trigger with phrases like "create kubernetes deployment", "generate k8s manifest", "deploy app to kubernetes", or "create service and ingress". Produces production-ready YAML with health checks, auto-scaling, resource limits, ingress configuration, and TLS termination.

# Creating Kubernetes Deployments

## Overview

This skill provides automated assistance for the described functionality.

## Prerequisites

Before using this skill, ensure:
- Kubernetes cluster is accessible and kubectl is configured
- Container image is built and pushed to registry
- Understanding of application resource requirements
- Namespace exists or will be created
- Ingress controller is installed (if using ingress)
- TLS certificates are available (if using HTTPS)

## Instructions

1. **Gather Requirements**: Application name, image, replicas, ports, environment
2. **Create Deployment**: Generate YAML with container spec and resource limits
3. **Add Health Checks**: Configure liveness and readiness probes
4. **Define Service**: Create ClusterIP, NodePort, or LoadBalancer service
5. **Configure Ingress**: Set up routing rules and TLS termination
6. **Add ConfigMaps/Secrets**: Externalize configuration and sensitive data
7. **Enable Auto-scaling**: Create HorizontalPodAutoscaler if needed
8. **Apply Manifests**: Use kubectl apply to deploy resources

## Output

**Deployment Manifest:**
```yaml
# {baseDir}/k8s/deployment.yaml

## Error Handling
