Kubernetes Manifest Generator

Step-by-step guidance for creating production-ready Kubernetes manifests including Deployments, Services, ConfigMaps, Secrets, and PersistentVolumeClaims.

Purpose

This skill provides comprehensive guidance for generating well-structured, secure, and production-ready Kubernetes manifests following cloud-native best practices and Kubernetes conventions.

When to Use This Skill

Use this skill when you need to:

  • Create new Kubernetes Deployment manifests
  • Define Service resources for network connectivity
  • Generate ConfigMap and Secret resources for configuration management
  • Create PersistentVolumeClaim manifests for stateful workloads
  • Follow Kubernetes best practices and naming conventions
  • Implement resource limits, health checks, and security contexts
  • Design manifests for multi-environment deployments

Detailed patterns and worked examples

Detailed pattern documentation lives in references/details.md. Read that file when the navigation tier above is insufficient.

Best Practices Summary

  1. Always set resource requests and limits - Prevents resource starvation
  2. Implement health checks - Ensures Kubernetes can manage your application
  3. Use specific image tags - Avoid unpredictable deployments
  4. Apply security contexts - Run as non-root, drop capabilities
  5. Use ConfigMaps and Secrets - Separate config from code
  6. Label everything - Enables filtering and organization
  7. Follow naming conventions - Use standard Kubernetes labels
  8. Validate before applying - Use dry-run and validation tools
  9. Version your manifests - Keep in Git with version control
  10. Document with annotations - Add context for other developers

Troubleshooting

Pods not starting:

  • Check image pull errors: kubectl describe pod <pod-name>
  • Verify resource availability: kubectl get nodes
  • Check events: kubectl get events --sort-by='.lastTimestamp'

Service not accessible:

  • Verify selector matches pod labels: kubectl get endpoints <service-name>
  • Check service type and port configuration
  • Test from within cluster: kubectl run debug --rm -it --image=busybox -- sh

ConfigMap/Secret not loading:

  • Verify names match in Deployment
  • Check namespace
  • Ensure resources exist: kubectl get configmap,secret

Next Steps

After creating manifests:

  1. Store in Git repository
  2. Set up CI/CD pipeline for deployment
  3. Consider using Helm or Kustomize for templating
  4. Implement GitOps with ArgoCD or Flux
  5. Add monitoring and observability

What it does

Generates production-ready Kubernetes manifests for Deployments, Services, ConfigMaps, Secrets, and PersistentVolumeClaims with built-in best practices like resource limits, health checks, and security contexts. Use this when you need to author K8s YAML that follows cloud-native conventions and is ready for multi-environment deployment.

Frequently asked

What Kubernetes resource types does this skill cover?
The skill covers Deployments, Services, ConfigMaps, Secrets, and PersistentVolumeClaims. It provides patterns for each resource type and how to combine them in production configurations.
Does this skill generate Helm charts or Kustomize templates?
No. This skill produces standard Kubernetes YAML manifests. The skill documentation references Helm and Kustomize as next steps for templating, but does not generate them itself.
What security practices does this skill enforce?
The skill emphasizes security contexts (non-root users, dropped capabilities), resource limits to prevent starvation, health checks for availability, and separation of sensitive data via Secrets rather than embedding in manifests.
Can I use this skill for multi-environment deployments?
Yes. The skill is designed to help you create manifests that work across multiple environments and includes guidance on naming conventions, labeling, and configuration management patterns that support multi-environment setups.
Does this skill include validation or dry-run testing?
The skill mentions validation and dry-run as best practices to perform before applying manifests, but does not automate these checks itself. It recommends using standard Kubernetes tools like kubectl validate.
