Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/rohitg00/awesome-claude-code-toolkit --skill kubernetes-operations
  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads kubernetes-operations automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

Always set resource requests and limits. Use topology spread constraints for high availability.

Troubleshooting Commands

# Pod diagnostics
kubectl describe pod <pod-name> -n <namespace>
kubectl logs <pod-name> -c <container> --previous
kubectl exec -it <pod-name> -- /bin/sh

# Resource usage
kubectl top pods -n <namespace> --sort-by=memory
kubectl top nodes

# Network debugging
kubectl run debug --image=nicolaka/netshoot --rm -it -- bash
nslookup <service-name>.<namespace>.svc.cluster.local

# Events sorted by time
kubectl get events -n <namespace> --sort-by='.lastTimestamp'

# Find pods not running
kubectl get pods -A --field-selector=status.phase!=Running

Anti-Patterns

  • Running containers as root without securityContext.runAsNonRoot: true
  • Missing resource requests/limits (causes scheduling issues and noisy neighbors)
  • Using latest tag instead of pinned image versions
  • Not setting PodDisruptionBudget for critical workloads
  • Storing secrets in ConfigMaps instead of Secrets (or external secret managers)
  • Ignoring pod anti-affinity for replicated deployments

Checklist

  • All containers have resource requests and limits
  • Liveness and readiness probes configured
  • Images use specific version tags, not latest
  • Secrets stored in Kubernetes Secrets or external vault
  • PodDisruptionBudget set for production workloads
  • NetworkPolicies restrict traffic between namespaces
  • Topology spread constraints or anti-affinity for HA
  • Helm values split per environment (staging, production)

Prepare azd-based Azure projects for deployment: generates azure.yaml, infrastructure (Bicep/Terraform), and Dockerfiles for the Azure Developer CLI (azd) workflow. USE ONLY when the user explicitly wants to use azd as the deployment tool, or the project already has an azure.yaml file. DO NOT USE FOR: non-azd deployments, Python App Service code-only deploys (use python-appservice-deploy), or cross-cloud migration (use azure-cloud-migrate). WHEN: prepare app for azd, create azure.yaml, set up azd infrastructure, modernize app for Azure with azd, deploy with azd, function app, timer trigger, service bus trigger, event-driven function, managed identity, generate Bicep, generate Terraform, create and deploy to Azure.

azure-deploy

microsoft/azure-skills

Execute Azure deployments for ALREADY-PREPARED applications that have existing .azure/deployment-plan.md and infrastructure files. DO NOT use this skill when the user asks to CREATE a new application — use azure-prepare instead. This skill runs azd up, azd deploy, terraform apply, and az deployment commands with built-in error recovery. Requires .azure/deployment-plan.md from azure-prepare and validated status from azure-validate. WHEN: "run azd up", "run azd deploy", "execute deployment", "push to production", "push to cloud", "go live", "ship it", "bicep deploy", "terraform apply", "publish to Azure", "launch on Azure". DO NOT USE WHEN: "create and deploy", "build and deploy", "create a new app", "set up infrastructure", "create and deploy to Azure using Terraform" — use azure-prepare for these.

Pre-deployment validation for Azure readiness. Run deep checks on configuration, infrastructure (Bicep or Terraform), RBAC role assignments, managed identity permissions, and prerequisites before deploying.
