Kubernetes Storage
Manage Kubernetes storage using kubectl-mcp-server's storage tools.
When to Apply
Use this skill when:
- User mentions: "PVC", "PV", "storage class", "volume", "disk", "storage"
- Operations: provisioning storage, mounting volumes, expanding storage
- Keywords: "persist", "data", "backup storage", "volume claim"
Priority Rules
| Priority | Rule | Impact | Tools |
|---|---|---|---|
| 1 | Verify storage class exists before PVC | CRITICAL | getstorageclasses |
| 2 | Check PVC status before pod deployment | HIGH | describe_pvc |
| 3 | Review access modes for multi-pod access | MEDIUM | get_pvcs |
| 4 | Monitor PV reclaim policy | LOW | getpersistentvolumes |
Quick Reference
| Task | Tool | Example |

| PVC details | describe_pvc |
describe_pvc(name, namespace) |
| Storage classes | getstorageclasses |

| List PVs | getpersistentvolumes |
getpersistentvolumes() |
