基于 SOC 职业分类
Configure Kubernetes autoscaling with HPA, VPA, and KEDA. Use for horizontal/vertical pod autoscaling, event-driven scaling, and capacity management.
Kubernetes backup and restore with Velero. Use when creating backups, restoring applications, managing disaster recovery, or migrating workloads between clusters.
Browser automation for Kubernetes dashboards and web UIs. Use when interacting with Kubernetes Dashboard, Grafana, ArgoCD UI, or other web interfaces. Requires MCP_BROWSER_ENABLED=true.
Cluster API lifecycle management for provisioning, scaling, and upgrading Kubernetes clusters. Use when managing cluster infrastructure or multi-cluster operations.
Kubernetes certificate management with cert-manager. Use when managing TLS certificates, configuring issuers, or troubleshooting certificate issues.
Cilium and Hubble network observability for Kubernetes. Use when managing network policies, observing traffic flows, or troubleshooting connectivity with eBPF-based networking.

Cost analysis and optimization using kubectl-mcp-server's cost tools.
Use this skill when:
| Priority | Rule | Impact | Tools |
|---|---|---|---|
| 1 | Find and delete unused PVCs | CRITICAL | find_orphaned_pvcs |
| 2 | Right-size overprovisioned pods | HIGH | get_resource_recommendations |
| 3 | Identify idle LoadBalancers | HIGH | get_services |
| 4 | Scale down non-prod off-hours | MEDIUM | scale_deployment |
| 5 | Consolidate small namespaces | LOW | Analysis |
| Task | Tool | Example |
|---|---|---|
| Namespace cost | get_namespace_cost | get_namespace_cost(namespace) |
| Cluster cost | get_cluster_cost | get_cluster_cost() |
| Unused PVCs | find_orphaned_pvcs | find_orphaned_pvcs(namespace) |
| Right-sizing | get_resource_recommendations | get_resource_recommendations(namespace) |

| Current State | Recommendation |
|---|---|
| CPU usage < 10% of request | Reduce request by 50% |
| CPU usage > 80% of request | Increase request by 25% |
| Memory < 50% of request | Reduce request |
| Memory near limit | Increase limit, monitor OOM |
