Pull request overview
Updates the Azure region used by three API Server Benchmark pipelines to run in uksouth instead of eastus2, aligning the pipeline stage name and the regions parameter passed into the shared competitive test job template.
Changes:
- Renamed the Azure stage from
azure_eastus2toazure_uksouthin three API server benchmark pipelines. - Updated the Azure
regionslist value fromeastus2touksouthin those pipelines.

The Dsv3 VM family (Standard_D2s_v3, Standard_D8s_v3, Standard_D16s_v3) is restricted with NotAvailableForSubscription in eastus2 for our subscription, causing pipelines 10, 9, and 38 to fail at Terraform apply. Switch to the equivalent Dv3 family (Standard_D2_v3, Standard_D8_v3, Standard_D16_v3) which is confirmed available. The only difference is Dv3 lacks premium SSD support, which is not needed for these benchmark workloads. Affected scenarios: - apiserver-vn100pod3k - apiserver-vn10pod100 - apiserver-cm100 - apiserver-vn100pod10k
The Dsv3 VM family is restricted with NotAvailableForSubscription in eastus2. Instead of changing VM SKUs (which breaks runkperf's hardcoded node affinity selectors), move the Azure stages to uksouth where Dsv3 SKUs are available. Changes: - Revert Dv3 SKUs back to original Dsv3 in all 4 tfvars files - Update all Azure stages in 4 pipeline YAMLs from eastus2 to uksouth Affected pipelines: - 100 Nodes 3k Pods (pipeline 10) - 10 Nodes 100 Pods (pipeline 9) - API Server List Configmaps (pipeline 38) - 100 Nodes 10k Pods
The ControlPlaneUnderlay in the ADO variable groups (API-Server-Lower-Max-Inflight, API-Server-Higher-CPU-Cores) is tied to eastus2. Moving this pipeline to uksouth causes a region mismatch error.
