version: "1.0.0" name: aks-known-issues license: MIT metadata: author: Microsoft version: "1.2.1" description: "Lookup documented AKS fixes only when the prompt includes an exact catalog signature and all of its qualifiers: VMCannotFitEphemeralOSDisk; NodePoolMcVersionIncompatible; 'NodeImageVersion is not accepted'; AKS SkuNotAvailable with size, location, and zone; ZonalAllocationFailed with insufficient zone capacity; OverconstrainedAllocationRequest with listed constraints; nested AKS vmssCSE/CSE VMExtensionError_OutboundConnFail, VMExtensionError_K8SAPIServerConnFail, or VMExtensionError_K8SAPIServerDNSLookupFail; or AllocationFailed with the full cataloged internal-error or insufficient-regional-capacity message. Never use for quota errors, code-only or bare wrappers, generic symptoms, incomplete signatures, or failures outside AKS; use aks-troubleshooting or azure-diagnostics."

AKS Known Issues

Quick Reference

Use the catalog.

When to Use This Skill

Named catalog signatures only. Generic AKS → aks-troubleshooting; non-AKS → no AKS skill.

If every qualifier for a catalog row is not present, do not use this skill. This catalog has no quota-error rows; route AKS quota incidents to aks-troubleshooting.

MCP Tools

None required. Use advertised read-only Azure tools or CLI queries.

Workflow

1. Capture exact code, nested message, operation, and AKS resource.
2. Require every qualifier; codes are not substrings.
3. Give cause, fix, citation, and read-only verification.
4. State what ran; require explicit approval before every mutation.
