AKS CSE: exact signature, verification and documented fix
Complete original CSE signature table. A bare VMExtensionProvisioningError or number is insufficient; all signatures require AKS vmssCSE context. Verification is read-only and not run; fixes require approval.
출력 예시
The outer `VMExtensionProvisioningError` or a number alone is insufficient; a
numeric exit requires AKS `vmssCSE`/CSE context.
| Signature | Cause | Verify, then documented fix | Microsoft Learn |
|---|---|---|---|
| `VMExtensionError_OutboundConnFail`, `ERR_OUTBOUND_CONN_FAIL`, or exit **50** | CSE cannot reach endpoints needed for node packages | Test `mcr.microsoft.com:443`; inspect firewall, proxy, NSG, UDR, and AKS egress rules; correct the blocking path | [OutboundConnFail](https://learn.microsoft.com/troubleshoot/azure/azure-kubernetes/error-codes/vmextensionerror-outboundconnfail) |
| `VMExtensionError_K8SAPIServerConnFail`, `ERR_K8S_API_SERVER_CONN_FAIL`, or exit **51** | Node cannot reach the API server on TCP 443 | Test the API FQDN on 443; inspect NSG, UDR, firewall/proxy, authorized IPs, private endpoint, and TLS inspection; correct the failing path | [APIServerConnFail](https://learn.microsoft.com/troubleshoot/azure/azure-kubernetes/error-codes/vmextensionerror-k8sapiserverconnfail) |
| `VMExtensionError_K8SAPIServerDNSLookupFail`, `ERR_K8S_API_SERVER_DNS_LOOKUP_FAIL`, or exit **52** | Node cannot resolve the API-server FQDN | Resolve the FQDN and inspect DNS port 53, forwarders, and private-zone records/links; correct DNS | [APIServerDNSLookupFail](https://learn.microsoft.com/troubleshoot/azure/azure-kubernetes/error-codes/vmextensionerror-k8sapiserverdnslookupfail) |라이선스

AKS Known Issues
Quick Reference
| Property | Value |
|---|---|
| Best for | Exact signature plus AKS operation |
| Output | Cause, fix, and Learn citation |
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
- Capture exact code, nested message, operation, and AKS resource.
- Require every qualifier; codes are not substrings.
- Give cause, fix, citation, and read-only verification.
- State what ran; require explicit approval before every mutation.
Error Handling
| Input | Response |
|---|---|
| Bare wrapper/number | Request nested signature and CSE context |
| Generic AKS | aks-troubleshooting |
| Non-AKS | No AKS skill |
