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:

# {baseDir}/k8s/deployment.yaml
